Abstract

The invention relates to a high strength non-stick paint for frying pans. The paint is formed by mixing of polytetrafluoroethylene, silicon oxide sol, alumina sol, zirconia sol, titanium oxide sol and an admixture. The admixture is made of tungstic acid, silicic acid, zinc oxide, titanium oxide and silicon carbide. According to the invention, polytetrafluoroethylene is taken as the matrix, silicon oxide sol, alumina sol, zirconia sol and titanium oxide sol are adopted as the adjuvants, so that the admixture can combine with the matrix perfectly so as to form a high hardness coating; tungstic acid, silicic acid, zinc oxide, boron nitride, titanium nitride and silicon carbide are made into the admixture, thus not only improving the coating hardness and strength, but also improving the high temperature resistance of the coating.

Description

technical field [0001] The invention relates to a non-stick pan in the field of daily life, in particular to a high-strength non-stick coating for a frying pan. Background technique [0002] The advent of "non-stick pans" has brought great convenience to people's lives. People don't have to worry about accidentally burning meat when cooking, and fish fillets sticking to the wall of the pot when frying fish. This kind of non-stick pan has nothing to do with the appearance of ordinary pans, it just has an extra layer of anti-stick pan coating on the inner surface of the pan. In general, the coating used for non-stick pan coating usually consists of polymer resin and various fillers. The polymer resin is the key component of the coating, endowing the coating with the bonding force of the substrate, and bonding other components into a whole Adhesion, as well as the impact and gloss properties of the coating. [0003] Fluorine resin non-stick coatings (commonly known as Teflon ...
