Problems solved by technology

[0002] As we all know, traditional cookware coatings such as silicone coatings and fluorocarbon coatings have poor high temperature resistance and can only work normally below 260°C. When the heating temperature exceeds their tolerance, the coating itself will not only smoke, but even release Toxic or carcinogenic substances, easy to pollute the environment and endanger people's health

Abstract

The invention discloses a high temperature-resistant ceramics coating for non-stick cookware, and a preparation method of the coating. The coating is prepared by mixing A composition and B composition with the weight ratio of 2.0-2.2:1.0-1.2, wherein the A composition consists of silicon oxide colloidal sol, aluminum oxide colloidal sol, zirconium oxide colloidal sol, mica powder, iron oxide black, high-temperature aluminium oxide, isopropanol, deionized water, carboxymethyl acetic acid, cellulose butyrate and fluoro silicone oil, and the B composition consists of methyltriethoxysilane, dimethoxydimethylsilane, triethoxyphenylsilane, isopropanol and ethanol; the preparation method comprises the steps of: and mixing the A composition and B composition with the weight ratio of 2.0-2.2:1.0-1.2, hermetically stirring and curing under 35 DEG C 150-200rpm state for at least three hours, thus obtaining the coating. For the high temperature-resistant ceramics coating, the high temperature-resistant stability of -Si-O0 bond is mainly utilized, so that the excellent high temperature-resistant performance of the coating is guaranteed.

Description

Technical field [0001] The invention relates to a coating for non-stick cooking utensils, in particular to a high-temperature resistant ceramic coating for non-stick cooking utensils and a preparation method thereof. Background technique [0002] As we all know, traditional cookware coatings such as silicone coatings and fluorocarbon coatings have poor high temperature resistance and can only work normally below 260°C. When the heating temperature exceeds their capacity, the coating itself will not only emit smoke, but also release Toxic or carcinogenic substances are easy to pollute the environment and endanger people's health. Summary of the invention [0003] In order to solve the above technical problems, the present invention provides a high temperature resistant ceramic coating for non-stick cookware and a preparation method thereof. The coating mainly utilizes the high temperature resistance stability of the -Si-O- bond, as well as polysiloxane and Inorganic components suc...
