Method of manufacturing a fluorocarbon-based coating film

Abstract

A method of contacting a substrate having a surface containing hydroxyl groups with a non-aqueous solution containing a material having a chrolosilyl group; washing if desired; coating the substrate with a non-aqueous solvent containing a compound having a fluorocarbon group and a chlorosilane group or a solvent containing a compound containing a fluorocarbon group and an alkoxysilane; and baking the substrate if necessary in order to form a fluorocarbon-based polymer coating film chemically bonded to the substrate surface. The hydroxyl groups on the substrate surface and chlorosilyl groups are reacted to form a thin film having a large number of silanol groups (—SiOH) capable of connecting the polymer coating film to the substrate to form a heat-, weather-, and wear-resistant film on various surfaces.

Description

This application is a continuation of
where n represents 0 or an integer; R represents an
where n represents 0 or an integer; R represents an alkyl
where n represents 0 or an integer; R represents an alkyl alkylene group or a hydrocarbon substituted group containing C═C, C≡C, a silicon atom or an oxygen atom; m represents 0 or 1; Y represents a hydrogen atom, an alkyl group, an alkoxy group, a fluorine-containing alkoxy group and a fluorine-containing alkyl group, OA′ represents an alkoxy group, and q represents 0, 1 or 2.

To harden the fluorocarbon-based polymer coating film to be formed, a cross-linking agent can be added.

More specifically, in the case where a non-aqueous solvent containing a compound having a fluorocarbon group and a chlorosilane group is used, a cross-linking which may be used is represented by a formula; SiX_SCl_4-s, where X represents a hydrogen group or a substituted group, such as an alkyl group; and s represents 0, 1 or 2. In the case of using a solvent containing a compound having a fluorocarbon group and an alkoxysilane group, a cross-linking agent which may be used is represented by a formula: SiY_t(OA″)_4-t, where Y represents a substituted group, such as an alkyl group; A″ represents a hydrogen atom or an alkyl group; and t represents 0, 1 and 2. In either case, it is possible to adjust the three-dimensional cross-linking degree in the fluorocarbon-based polymer coating film that is formed, thus controlling the hardness of the fluorocarbon-based coating film.

Furthermore, it is possible to coat in ways similar to the prior art fluorocarbon-based coating film by dispersing fine particles of the fluorocarbon-based polymer in a non-aqueous solvent containing a compound having a fluorocarbon group and a chlorosilane group or in a solvent containing a compound having a fluorocarbon group and an alkoxysilane group. In this case, fluorocarbon chains, siloxane bonds and molecular chains of the fluorocarbon-based polymer entangle on a molecular level with each other. Thus, a fluorocarbon-based polymer coating film may be formed, that has very high adhesion compared to the prior art coating film.

As has been described in the foregoing, the method of manufacturing a fluorocarbon-based coating film according to the invention comprises the steps contacting a substrate having a surface containing hydroxyl groups with a non-aqueous solution containing a material containing a chlorosilyl group; coating the substrate with a non-aqueous solution containing a compound containing a fluorocarbon group and a chlorosilane group or a solution containing a compound containing a fluorocarbon group and an alkoxysilane group; and baking the substrate after the contacting and coating steps. Thus, a fluorocarbon-based coating film excellent in the hydrophobic and oil-repellent properties can be formed on the surface of a hydrophilic substrate with the properties being strongly chemically bonded to the substrate, high density, no pinholes, uniform thickness and very thin layer. It is thus possible to provide a fluorocarbon-based coating film having high durability and high performance.

Now, examples will be described with reference to FIGS. 1 to 4.

EXAMPLE 1

A hydrophilic substrate 1, i.e., a glass substrate, was prepared as shown in FIG. 1(a).

The substrate 1 was coated with what was obtained by dissolving 1% wt of Cl—(SiCl₂O)₂—SiCl₃ as the material having a chlorosilyl group in chloroform solvent.

Also, hydrophilic —OH substitute groups were contained on the surface of the substrate 1. Thus, a hydrochloric acid removal reaction (dehydrochloric acid) was brought about on the surface to fix molecules to the surface of the substrate 1 via —SiO— bonds, for example as shown by the formula [1]; ##STR00001##

With subsequent evaporation of the chloroform solvent in an atmosphere containing moisture from water content, a siloxane polymer coating film 2 as shown in FIG. 1(b) was formed with hydrochloric acid removal reaction between the moisture and —Cl groups without being reacted with the substrate 1.

The siloxane polymer coating film 2 thus formed was bonded to the surface of the substrate 1 via chemical bonds of —SiO— and thus difficult to be separated.

The siloxane polymer coating film 2 had a large number of —SiOH bonds on the surface.

Accordingly, a solution containing 80% wt n-hexadecane, 12% wt carbon tetrachloride and 8% wt chloroform was prepared by dissolving into a concentration of 2.0% wt CF₃CH₂O(CH₂)₁₅SiCl₃ as a non-aqueous solvent containing a compound having a fluorocarbon group and a chlorosilane group, and it was coated on the surface of the substrate 1 having the surface thereof formed with the siloxane polymer coating film 2 having a large number of —SiOH bonds, as shown in FIG. 1(c). Then, by baking in an atmosphere containing water moisture at 200° C. for about 30 minutes, a hydrochloric acid removal reaction was brought about between the chlorosilyl groups of fluorine-containing chlorosilane-based surface active agent and exposed —OH groups of the siloxane polymer coating film 2 to form covalent bonds such as the following formula[2]; ##STR00002##

In this way, a fluorocarbon-based polymer coating film 3 having a thickness of about 10 to 20 μm was obtained.

This polymer film 3 was not separated at all in a checkerboard test.

Further, by adding 3% wt of SiCl₄ as a cross-linking agent to the non-aqueous solution containing a compound having a fluorocarbon group and a chlorosilane group, a fluorocarbon-based coating polymer film 3 was obtained, which had about two times of the hardness of a solvent without SiCl₄, caused by three-dimensional cross-linking through —Si(—O—)₃ bonds.

Further by carrying out similar coating by adding 20% wt of fine particles of polytetrafluoroethylene as fluorocarbon-based polymer to the non-aqueous solvent containing a compound having a fluorocarbon group and a chlorosilane group, a fluorocarbon-based coating film was obtained, which had very superior adhesion as compared to that in the prior art even though its hardness was comparable to that in the prior art.

EXAMPLE 2

A hydrophilic substrate 1 was prepared as same as in Example 1, as shown in FIG. 2(a).

The substrate 1 was dipped for about one hour in a solution obtained by dissolving 1% wt of Cl—(SiCl₂O)₂—SiCl₃ as a material having chlorosilyl groups in chloroform solvent as in Example 1. A hydrochloric acid removal reaction thus was brought about on the surface of the substrate 1 because of the presence of hydrophilic —OH groups on the surface to adsorb molecules as shown above formula[1].

By subsequently carrying out washing with a non-aqueous solvent, i.e., chloroform, and then with water, molecules of Cl—(SiCl₂O)₂—SiCl₃ which remained without being reacted with the substrate 1, were removed to leave a siloxane monomolecular film 4 on the surface of the substrate 1 as shown in FIG. 2(b) and given as the formulas [A] and/or [B] etc. ##STR00003##

The monomolecular film 4 thus obtained was perfectly bonded to the substrate 1 via chemical bonds of —SiO— and was not easy separated.

The monomolecular film thus formed has many —SiOH bonds on the surface.

Further, a non-aqueous solution containing 80% wt n-hexadecane, 12% wt carbon tetrachloride and 8% wt chloroform was prepared by dissolving into a concentration of 2.0% wt a compound having fluorocarbon group and chlorosilane group such as CF₃(CF₂)₇(CH₂)₂SiCl₃ coated on the surface substrate 1 formed on the surface thereof with a monomolecular film 4 having many —SiOH bonds as shown in FIG. 2(c). A reaction was thus brought about between —SiCl bonds and —SiOH groups of the monomolecular layer 4. Then, by baking in an atmosphere containing water moisture at 200° C. for about 30 minutes, the bonds of formula[3] were formed: ##STR00004##

In this way, a polymer film 5 having a thickness of 10 to 20 μm was formed such that it was chemically bonded to the inner-layer, i.e., the siloxane polymer monomolecular film 4.

The coating film did not separate in a checkerboard test.

Furthermore, by adding 15% wt of SiCl₄ as a compound cross-linking agent to the non-aqueous solution containing a compound having a fluorocarbon group and a chlorosilane group, a fluorocarbon-based polymer coating film having a hardness increased by about 5 times could be obtained. Additionally, by carrying out similar coating using a non-aqueous solution containing a compound having a fluorocarbon group and a chlorosilane group, which was obtained by dispersing about 20% wt of fine particles of a fluorocarbon-based polymer, e.g., polytetrafluoroethylene, a fluorocarbon-based polymer coating film could be obtained that had very superior adhesion compared to that in the prior art although its hardness was comparable to that in the prior art.

While this example used CF₃CH₂O(CH₂)₁₅SiCl₃ and CF₃(CF₂)₇(CH₂)₂SiCl₃ as the fluorocarbon-based surface active agent, by adding the C═C or C≡C group to or assembling it in an alkyl alkylene chain portion, cross-linking can be obtained by irradiation with an electron beam of about 5M-rads after the formation of the coating film, and thus it is possible to increase the hardness of the coating film to about 10 times.

Further, as the fluorocarbon-based surface active agent, materials shown below may be used in addition to the above agents,

• • CF₃(CH₂)₂Si(CH₃)₂(CH₂)₁₅SiCl₃, F(CF₂)₄(CH₂)₂Si(CH₃)₂(CH₂)₉Si Cl₃ and CF₃COO(CH₂)₁₅SiCl₃.

EXAMPLE 3

As shown in Example 1, a hydrophilic substrate 11 was prepared as shown in FIG. 3(a).

This substrate 11 was then dipped in a solution obtained by dissolving 1% wt of a material having a chlorosilyl group in a non-aqueous solvent such as a chroloform solvent and then was raised from the solution.

By using Cl—(SiCl₂O)₂—SiCl₃ as a material having a plurality of chlorosilyl groups in a molecule, a hydrochloric acid removal reaction was brought about because of the presence of hydrophilic —OH groups on the surface of the substrate 11, thus fixing molecules to the substrate via —SiO— bonds as shown above formula [1].

By subsequently evaporating the chloroform solvent in an atmosphere containing of moisture, chlorine in —SiCl groups that remained without being reacted with the substrate 11 were then reacted with the water by a hydrochloric acid removal reaction to form a siloxane polymer coating film 12 as shown in FIG. 3(b).

As the siloxane polymer coating film 12 thus obtained was bonded to the surface of the substrate 11 via chemical bonds of —SiO—, it was difficult to be separated.

The siloxane polymer coating film 12 formed also had many —SiOH bonds on the surface.

Furthermore, a solution obtained by dissolving a concentration of several percent, for instance 10% wt, of a compound having a fluorocarbon group and a alkoxysilane group, for instance CF₃CH₂O(CH₂)₁₅Si(OCH₃)₃ in an alcohol solvent, for instance ethanol, was used for coating, followed by baking at 200° C. for about 30 minutes. By doing so, —OH groups exposed to the surface of the siloxane polymer coating film 12 were reacted with alkoxy groups in the fluorine-containg alkoxysilane-based surface active agent an alcohol removal reaction to form such as the formula [4]. ##STR00005##

In this way, a polymer film 13 having a thickness of 10 to 20 μm was obtained.

This polymer film 13 did not separate in a checkerboard test. Further, by adding 5% wt of Si(OCH₃)₄ as a cross-linking agent to the solvent containing a compound having a fluorocarbon group and an alkoxysilane group shown by the above formula [4], a three-dimensionally cross-linked fluorocarbon-based film via —SiCl(—O—)₃ bonds was obtained, which had about two times the hardness of the film obtained without addition of Si(OCH₃)₄.

Further, by carrying out similar coating using a solution containing a compound having a fluorocarbon group and an alkoxysilane group, to which 20% wt of fine particles of polytetrafluoroethylene were added as a fluorocarbon-based polymer, a polymer film was obtained, which had a very superior adhesion compared to that in the prior art although its hardness was comparable to that in the prior art.

EXAMPLE 4

As shown in Example 3, a hydrophilic substrate 11 as shown in FIG. 4(a) was dipped for about one hour in a non-aqueous solution prepared by dissolving 1% wt of Cl—(SiCl₂O)₂—SiCl₃ as a material containing a chlorosilyl group, for instance, in a chloroform solvent.

At this time, hydrochloric acid removal reaction occured on the surface of substrate 11 because of the presence of hydrophilic —OH groups on the surface. Thus, molecules were adsorbed as shown by the formula such as formula [1]. When the substrate was exposed to an atmosphere containing water, a siloxane monomolecular film 14 as shown in FIG. 4(b) was obtained on the substrate surface, and shown such as the formula [5] and/or formula [6] etc. ##STR00006##

The monomolecular layer 14 thus obtained did not separate as it was perfectly bonded to the substrate 1 via —SiO— chemical bonds.

The monomolecular layer 14 obtained also had many —SiOH bonds.

Further, a solution was prepared by dissolving a concentration of 2% wt CF₃(CF₂)₇(CH₂)₂Si(OC₂H₅)₃ as a compound having a fluorocarbon group and an alkoxysilane group in a methanol solvent, coated onto the surface of substrate 11 covered with a monomolecular film having many —SiOH bonds, and followed by baking at 200° C. for about 30 minutes.

This produced the compound shown in FIG. 4(d) and represented by formula[7]. ##STR00007##
In this way, a polymer film 15 having a thickness of 10 to 20 μm was obtained.

The polymer film 15 formed did not separate in a checkerboard test, because it was formed in a state chemically bonded to the siloxane monomolecular film 14.

Further, by adding 10% wt of Si(OC₃H₇)₄ as the cross-linking agent to the solution having a compound containing a fluorocarbon group and an alkoxysilane group, a fluorocarbon-based coating film having about four times the hardness of the film was obtained as compared to a film without the addition of the agent. Furthermore, by carrying out similar coating using a solution containing a compound having a fluorocarbon group and an alkoxysilane group, in which solution was dispersed 20% wt of fine particles of polytetrafluoroethylene, a fluorocarbon-based coating film was obtained, which had a very superior adhesion compared to that in the prior art although its hardness was comparable to that in the prior art.

Although in the above Examples 3 and 4, CF₃CH₂O(CH₂)₁₅Si(OCH₃)₃ and were CF₃(CF₂)₇(CH₂)₂Si(OC₂H₅)₃ were used as a reagent for forming a fluorocarbon-based film on the uppermost surface by adding or assembling the C═C or C≡C group to or in the alkyl chain portion, cross-linking can be caused by irradiation of an electron beam of about 5M-rads. After the formation of the coating film, a coating film with about 10 times of the hardness to be obtained.

Further, as the compound having a fluorocarbon group and a chlorosilyl group or a fluorocarbon group and an alkoxysilane group,

• • CF₃(CH₂)₂Si(CH₃)₂(CH₂)₁₅Si(OCH₃)₃,
  • F(CF₂)₄(CH₂)₂Si(CH₃)₂(CH₂)₉Si(OCH₃)₃ and
  • CF₃COO(CH₂)₁₅Si(OC₂H₅)₃ may be used, in addition to the compounds noted in the above Examples 1 to 4.

The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiment is to be considered in all respects as illustrative and not restrictive.
