Abstract

The invention relates to a nanometer SiO2 hybrid polyester modified organosilicon non-stick paint. The non-stick paint is prepared mainly by mixing the following components by weight: 50 to 70 parts of a nanometer SiO2 hybrid polyester modified organosilicon resin, 3 to 10 parts of an epoxy resin, 3 to 10 parts of a melamine resin, 3 to 10 parts of a filling material, 20 to 30 parts of an organic solvent, 1 to 5 parts of a non-stick auxiliary agent, 0.3 to 1 part of a polymeric dispersant and 1 to 3 parts of an adhesion promoter. A coating prepared through coating of the non-stick paint has the characteristics of good non-stick performance, good temperature tolerance, excellent chemical resistance, corrosion resistance, high hardness and the like, is especially applicable to non-stick coatings for ferrous baking equipment and a cake mould and accords with relevant FDA and LFGB standards for food contact materials. According to the invention, the technical defect of a high sintering temperature (normally, higher than 380 DEG C) of a conventional fluoro paint is overcome; and the non-stick paint provided by the invention only needs a sintering temperature of about 280 DEG C, so a phosphating film on the surface of a ferrous substrate is protected, resistance to chemical corrosion is improved, and energy saving and environmental protection are realized.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a non-stick coating of nano-SiO2 hybridized polyester modified organic silicon and a coating method thereof. Background technique [0002] Polyester modified silicone is a kind of polymer material. From the perspective of molecular structure, it contains silicone with excellent weather resistance, heat resistance, gloss retention, low temperature flexibility, low surface free energy and stain resistance. At the same time, it contains polyester segments with good physical and mechanical properties and chemical corrosion resistance; at the same time, this kind of material overcomes the defects of silicone resin and polyester, and improves the performance of the material. The nano-SiO2 hybrid polyester-modified silicone resin, due to the nano-SiO2 hybridization, makes it a nano-interpenetrating network, which makes it better than polyester-modified silicone in terms of wear resista...
