Problems solved by technology

[0004] Because the non-stick coating applied on this kind of pot body will finally get another kind of concave-convex non-stick coating that is different from ordinary smooth coatings, this special-effect coating looks more textured and makes people feel more comfortable. Refreshing, it is also sought after by many people today when people have diversified aesthetic requirements for products, but this kind of shot blasting process for the pot body is more complicated and consumes a lot of resources, so the cost is also higher

Abstract

The invention provides a non-stick coating used on the surface of a cooking utensil. The non-stick layer comprises a bottom coating body, a middle coating body and a surface coating body. The bottom coating body is cured first after construction to obtain a coating body with the effect similar to the shot blasting effect, then middle paint and surface paint are sprayed on the bottom coating body in a wet mode, and finally the coating with a special effect similar to the shot blasting effect is obtained. The coating is high in hardness, excellent in abrasion resistance and good in non-stick performance.

Description

technical field [0001] The invention relates to the technical field of non-stick coatings, in particular to a non-stick coating with a shot-blasting effect used on cookware and a preparation method thereof. Background technique [0002] Since the birth of non-stick cookware, it has quickly gained people's love for its advantages of environmental protection, health and beauty. Ethylene (PTFE), its friction coefficient is extremely small, and its critical surface tension is 18.5×10 -3 N / m, so it is not easy to be wetted by liquid, that is, it has very good non-stickiness. [0003] After decades of application and development of non-stick cookware, this kind of non-stick coating with polytetrafluoroethylene as the main component has become more and more mature. However, due to the low strength and poor friction resistance of PTFE itself, the fluorine coating produced by it There are also disadvantages of low hardness and wear resistance, which also reduces the non-stick prope...
