目的としている。In the above-mentioned conventional coating method, a silicon oil layer is formed on the coating film, and when the silicon oil content decreases due to evaporation due to an increase in the outside air temperature or the like. The non-adhesiveness is suddenly reduced, and the release of silicone oil layer occurs.
This layer is liable to be lost due to a rise in temperature (100 ° C. or higher) or other causes, and if it is lost, the non-adhesive strength is sharply reduced, and in any case, there is a problem in durability. The present invention analyzes the relationship between the composition and durability of a conventional silicone oil-containing resin paint, and as a result of intensive research on a composition that does not cause separation of silicone oil,
It is an object of the present invention to complete the present invention by focusing on a composition in which silicone oil is evenly dispersed in a resin coating film layer, and to provide means for forming a non-adhesive film having excellent durability on a metal surface.

3Si [NHSiH2] nNHSiH3), a polymer of preceramic polymers, such as trade name "Sera set TM.
SN polysilazane polymer solution "is used. Polyurea resin is a heat-resistant thermosetting resin and has an effect of increasing the adhesive strength of a film layer. Silazane has an effect of dispersing and fixing silicon oil in the coating layer on average. The preceramic polymer forms a hard coating layer. This polyureasilazane preceramic polymer liquid is characterized in that the volume of the cured product at room temperature does not change. That is, the components do not evaporate and do not shrink due to heat, and the silicon oil is dispersed and sealed in the coating layer on average, so that the conventional evaporation and layer separation of the silicon oil due to the layering of the silicon oil occur. Prevention improves durability.

After 3 to 7μ, 6% by weight of silicone oil is added to 100 parts of CeraSet ™ SN polysilazane polymer solution
After mixing and stirring to form a non-adhesive coating material, a non-adhesive coating was prepared by mixing silicon oil in the range of 4 to 8% by weight with respect to 100 parts of the polyurea silazane preceramic polymer liquid on the metal rough surface. The coating material was applied to a thickness of about 10 to 15 μ and heated at 240 ° C. for 15 minutes to form a durable non-adhesive film. An attempt was made to attach a gum tape or a cellophane tape to this durable non-adhesive film, but it could not be attached. The processed metal plate is kept at 110 ° C for 10 minutes.
Return to room temperature by heating at 0 ° C, soak in water at 0 ° C for 10 minutes, return to room temperature, and repeat the heating and cooling 10 times to try to attach gum tape or cellophane tape, but the non-adhesion is slightly deteriorated Did not. No peeling of the upper layer of the durable non-adhesive film was observed. When a test was conducted by changing the mixing ratio of this silicone oil, a slight tackiness was observed at less than 4% by weight, so that 4% by weight or more was preferred, and even at more than 8% by weight, no significant difference was observed in the effect. It has been found that the mixing ratio of silicon oil to 100 parts of the polyureasilazane preceramic polymer liquid is sufficient if it is in the range of 4 to 8% by weight.
