Super-strength non-stick coating and construction method thereof

Abstract

The invention belongs to the technical field of the chemical industry coating, and particularly relates to a super-strength non-stick coating and a construction method thereof. The super-strength non-stick coating is successively provided with a bottom coating and a middle coating from top to bottom. The bottom coating comprises the following raw materials in parts by matching: 8-30 parts of a bonder, 0.5-5 parts of high-temperature resisting pigment, 5-25 parts of high-temperature resisting filler, 0.5-2.5 parts of an assistant, and the balance of water; and the middle coating comprises the following raw materials in parts by matching: 8-25 parts of fluororesin, 8-20 parts of the bonder, 0.5-10 parts of the high-temperature resisting pigment, 0.5-2.5 parts of the assistant, and the balance of the water. The disclosed super-strength non-stick coating and the construction method thereof can be applied to non-stick cookers. The super-strength non-stick coating has an excellent non-stickproperty, and is easy to clean. In addition, because the coating has super-strength, abrasion resistance and scratch resistance are greatly superior to a common non-stick coating.

Description

Technical field [0001] The invention relates to a super-strength non-stick coating and a construction method thereof. It belongs to the technical field of chemical coatings, and is a chemical coating for coating liquid or other fluids on the surface. Background technique [0002] Non-stick coatings are more and more widely used on non-stick cookware due to their unique advantages of non-stickiness, no oily smoke, and easy cleaning. At present, some daily utensils are coated with coatings, such as pots and pans, for the purpose of preventing sticking. Non-stick cooking utensils with metal substrates (including woks and inner pots of small kitchen appliances such as rice cookers and electric pressure cookers) are in direct contact with the non-stick coating, because the non-stick coating is not completely dense or after long-term use , The non-stick coating will have some micropores, especially the micropores of the water-based fluoropolymer coating. Therefore, during the use of...

AI Technical Summary

Problems solved by technology

Die-cast aluminum substrates with high silicon content or substrates coated with aluminum are more prone to galvanic corrosion, which seriously affects the quality of aluminum-based non-stick pans

[0003] Non-stick coatings and cooking utensils are introduced to China from Europe, America and other countries, and their products may not be acclimatized in the Chinese market. For example, Chinese cooking habits are very different from those of the European Union. Shoveling, stir-frying and frying, Europe and the United States tend to fry more, so the traditional non-stick cookware used in China will soon have coating discoloration, scratches and paint peeling and lose its function and cannot be used
