Futrous resins such as tetrafluoroethylene resin and tetrafluoroethylene-hexafluoropropylene copolymer have excellent heat resistance and chemical resistance, and also have properties such as non-adhesion. There is. Applications that take advantage of the characteristics of fluoroplastics include kitchen appliances such as rice cookers, thermal jars, and frying pans, and mechanical parts such as rollers for copying machines.These are made by coating metals such as aluminum and stainless steel with fluoroplastics. has been done. In particular, kitchen utensils made of aluminum coated with a fluorine-based resin have rapidly become popular in recent years, and in addition to the aforementioned jars and frying pans, fluorine-based resin-coated items are also used in hot plates, electric pots, and the like. Among these fluorocarbon resins, the one with the most excellent properties is tetrafluoroethylene resin (PTFE). When coating a metal with a fluorine-based resin, a coating method different from that of normal painting is used because the resin does not easily adhere to the metal. In the case of aluminum, there are two main methods: chemical bonding and mechanical bonding.
The former method is called a primer method, and is a method in which a primer layer having adhesive properties to both aluminum and fluorine resin is provided between the aluminum and fluorine resin, and the fluorine resin and aluminum are bonded through this layer. The latter is called the etching method, and is a method in which fine octopus-shaped irregularities are created on the aluminum surface, and the fluorine-based resin penetrates into these ridges and recesses, creating an anchoring effect that mechanically bonds the aluminum and the fluorine-containing resin. . In this way, the method of coating with a fluorine-based resin requires a complicated construction method that is not found in coating with other resins. In the case of the primer method, a so-called two-coat, two-bake coating method is required, in which a primer is usually applied and baked at a high temperature, and then a fluorocarbon resin is applied and baked. The problem was that the material was limited to aluminum. The present inventors have solved these problems and made it easier and cheaper to use metal aluminum than conventional ones.
In order to develop a method of coating a fluorine-based resin that can be applied to base materials such as stainless steel and has high adhesion between the base material and the resin, various studies have been conducted, and as a result, the present invention has been completed. In other words, the feature of the present invention is that at least one epoxy group or amino group and a silicon-bonded functional group (represented by Si-OR, R is a hydrogen atom, an alkyl group, an acyl group, or an Si-X, After pre-coating an organosilicon compound having (X is a halogen atom) on a metal base material, a fluorocarbon resin dispersion containing an inorganic filler such as a pigment in an amount of 1% by weight or more based on the resin is coated thereon. , then heating and
It is to perform burning. The organosilicon compound used in the present invention is a type of compound called a silane coupling agent. This silane coupling agent generally has vinyl groups,
It is an organosilicon compound consisting of organic functional groups such as amino groups or epoxy groups, and functional groups such as halogen, alkoxy groups, and acetoxy groups. Typical examples of these are vinyltriethoxysilane CH 2 =CHSi(OC 2 H 5 ) 3 or γ-aminopropyltriethoxysilane NH 2 (CH 2 ) 3 Si

[Formula] etc. As can be seen from these chemical structures, the silane coupling agent is a reactive organosilicon compound that has affinity for both the organic phase and the inorganic phase in one molecule. Conventionally, the method of adhering futsuo-based resin and metal using this silane coupling agent was disclosed in Japanese Patent Publication No.
50-2036 or JP-A-52-50328. All of these are tetrafluoroethylene-
A film made of a material other than tetrafluoroethylene resin, such as hexafluoropropylene copolymer (FEP), ethylene-tetrafluoroethylene copolymer, or vinyl fluoride resin, is further attached via aminosilane. Therefore, a technique for bonding tetrafluoroethylene resin using such a silane coupling agent was completely unknown. The present inventors investigated various methods of adhering tetrafluoroethylene resin to base materials such as metals using this silane coupling agent, and found that a silane coupling agent having an epoxy group or an amino group can be used as a base material. It has been revealed that the adhesion of the fluorocarbon resin to the substrate can be greatly enhanced by applying it in advance and then further coating it with a fluorocarbon resin dispersion containing pigments and the like. In this case, the preferred method for applying the silane coupling agent is to dissolve the coupling agent in a solvent such as water or alcohol, apply it by spraying, and then dry it. These epoxy silanes include

(OCH 3 ) N-β-(aminoethyl)- shown in 3
Examples include γ-aminopropyltrimethoxysilane. In the case of the present invention, when an inorganic filler such as a pigment is present in the fluorine resin dispersion, there is an effect of enhancing adhesive strength, and the content of the filler needs to be 1% by weight or more based on the resin. . Furthermore, among these fillers, TiO 2 (titanium dioxide) and Fe 2 O 3 , which are used as white pigments, are used as white pigments.
It has become clear that (Red Garla) has a particularly large effect. As described above, the present invention provides a method for coating a fluorine resin that is easier and cheaper than conventional methods, can be applied to a wide range of base materials, and has high adhesiveness between the base material and the fluorine resin. It can be widely applied to various kitchen appliances or machine parts that take advantage of the non-adhesive properties of the coated surface.

Ethanol solutions of (CH 2 ) 3 Si(OCH 3 ) 3 ) were prepared. (Concentration: 10% by weight) This was applied to each aluminum plate roughened by sandblasting, and dried at 100°C for 10 minutes. Table 1 on this side
Apply various tetrafluoroethylene dispersions shown in
After drying at 100°C for 10 minutes, sintering was performed by heating at 380°C for 20 minutes. The adhesive strength between the aluminum and resin of the resulting coating was measured by 180° peel strength. For comparison, a similar type of aluminum plate was coated without the addition of a silane coupling agent, and the adhesive strength was measured. These results are shown in Table 1.
