Abstract

The invention relates to an anti-adhesion paint and a product coated by the anti-adhesion paint. The purpose of the anti-adhesion paint is to solve the problems of relatively bad leveling performance and bad post-film-formation flatness of poly-(ether-ether-ketone). According to the invention, polyether sulphone is added into the poly-(ether-ether-ketone) paint and the proportions of the ingredients are adjusted, so that an anti-adhesion paint of good leveling performance, excellent high-temperature resistance, excellent corrosion resistance and excellent weather resistance is obtained. The anti-adhesion paint disclosed by the invention comprises the following ingredients in parts by weight: 1-20 parts of poly-(ether-ether-ketone), 20-50 parts of polyether sulphone, 1-40 parts of anti-adhesion agent, 1-30 parts of pigment, 20-50 parts of water and 1-40 parts of organic solvent. The anti-adhesion paint disclosed by the invention can be used for products with anti-adhesion requirements and especially for outdoor products or kitchenware products with relatively high weather-resisting and scratch-resisting requirements.

Description

technical field [0001] The invention relates to an anti-blocking coating. More specifically, the present invention relates to an anti-blocking coating that combines the respective advantages of polyethersulfone and polyether ether ketone, and articles coated with the coating. Background technique [0002] Heat-resistant anti-adhesion coatings were first used on cooking utensils such as pots. With the increasing diversification of people's needs, how to improve the thermal fluidity of anti-blocking coatings, thereby improving the corrosion resistance (including salt corrosion resistance, acid and alkali corrosion resistance, etc.), wear resistance, and weather resistance of the formed coating It is a long-term goal of technical personnel to use the coating for more purposes. [0003] In the field of high temperature and corrosion resistant materials, polyetheretherketone (PEEK) is one of the most widely used materials. Polyether ether ketone is a new type of semi-crystalli...
