しかし、現在一般に使用されている無機質ケイカル板は
ノンアスベスト化の傾向にあり、その耐熱温度は２００
℃程度に低下しており、従来の３００〜５００℃という
高い温度での焼付は難しい。[Prior art] Conventionally used polysiloxanes with a high ladder structure have residual silanol groups in their skeletons, so they can be heated to accelerate hardening. JP-A No. 62-37378 and JP-A No. 62-122133 state that when alkyl silicate is used as a binder, if baked at 300 to 500°C, the coating film will have hard chemical resistance, weather resistance, and insulation resistance. 6 However, the inorganic silica boards currently in general use tend to be non-asbestos, and their heat resistance temperature is 200°C.
It is difficult to bake at the conventional high temperature of 300 to 500°C.
そのため２００℃以下で焼付でき、しかも高度な塗膜性
能をもつ塗料が必要となっている。Therefore, there is a need for paints that can be baked at temperatures below 200°C and have high film performance.

る。In addition, the coating film thickness is about 3 to 5 μm thick, and if the film is thicker than that, cracks will occur in the coating film, making it impossible to obtain a coating film that can be used for practical purposes. Thickness is 100~1
There is also a need for a paint that can yield about 50 micron cocoons.
従って、本発明の目的は１５０〜２００℃の焼付温度で

低温焼付型の無機質塗料を提供することにある。Therefore, the object of the present invention is to form a coating film with excellent water resistance, heat resistance, boiling resistance, abrasion resistance, chemical resistance, and weather resistance at a baking temperature of 150 to 200°C, and a coating thickness of 100 to 150μ. The object of the present invention is to provide a low-temperature baking type inorganic paint.

The present invention was completed based on the discovery that a chemical-resistant coating film can be obtained by baking at a low temperature of 150 to 200°C.

る。As a Si alkoxide partial hydrolyzate, the molar ratio with the OR group of Si alkoxide is less than 1.1, preferably 0.08 to 0.
6 was hydrolyzed with water, and the residual rate of OR groups was 3.
It is 0 to 70 mol%. When the Si alkoxide partial hydrolyzate has an OR group residual rate of 100 to 70 mol %, a dense film cannot be obtained, it becomes porous, and it is difficult to obtain hardness. Furthermore, if the Si alkoxide partial hydrolyzate has an OR group residual ratio of 0 to 30%, the film-forming property during coating is reduced, workability is poor, and the coating film cracks during curing.

部分加水分解物が得られる。As means for obtaining a partial hydrolyzate of Si alkoxide, there are known methods such as hydrolysis at room temperature, hydrolysis under reflux, and hydrolysis with the addition of a catalyst. For example, alcohols such as ethyl alcohol, isopropyl alcohol, and methyl alcohol, which are compatible with water, are added to a Si alkoxide solution. Furthermore, when acidic water containing hydrochloric acid, acetic acid, etc. is added to the solution in an amount (number of moles) less than the total number of moles of alkoxide groups of Si alcohol, a transparent partial hydrolyzate of Si alkoxide is obtained.

膜化した場合に亀裂が発生し易い。The amount of Si alkoxide hydrolyzate added is preferably 10 to 40% by weight in S + O2 minutes; if it is less than 10% by weight, the coating film strength will be weak and the effect of improving moisture resistance, chemical resistance, weather resistance, and strength will be small. , and if it exceeds 40% by weight, Si
The viscosity of the mixed liquid of the alkoxide partial hydrolyzate and the resin is low, and in the case of a porous substrate, the permeability is high, making it difficult to form a film. Furthermore, it is difficult to increase the thickness of a substrate that is difficult to permeate with water, and cracks are likely to occur when the thickness of the substrate is increased.

［発明の効果］
本発明の耐薬品性無機質塗料は２００℃以下の温度でも
焼付することができ、例えばノンアスベスト化の傾向に
あり耐熱性が低下しているケイカル板面に耐水性、耐熱
性、耐煮沸性、耐摩耗性、耐薬品性、耐候性に優れた塗
膜を形成することができる。[Effects of the Invention] The chemical-resistant inorganic paint of the present invention can be baked even at temperatures below 200°C, and provides water resistance and heat resistance to, for example, the surface of a silica board, which tends to be non-asbestos and has lower heat resistance. It is possible to form a coating film with excellent boiling resistance, abrasion resistance, chemical resistance, and weather resistance.
