Abstract

The invention relates to the technical field of nonstick coatings, aims to solve the problems that a film breaks, food is scorched and the service life of the coating is greatly shortened due to heat gathering points easily caused by poorer heat distribution of non-stick pans taking a stainless steel pot and an iron pot as substrates and provides a nonstick coating with high heat conductivity and high wear resistance. The film formed by the coating has excellent mechanical strength, higher heat conductivity and also has the characteristics of low VOC emission, environmental protection and absence of toxicity.

Description

technical field [0001] The invention relates to the technical field of non-stick coatings, in particular to a non-stick coating with high thermal conductivity and high wear resistance. Background technique [0002] Due to its very low surface tension, non-stick coatings make it difficult for other substances to adhere to the surface. The non-stick pans made of it have brought great convenience to people's lives since they came out. Non-stick pans are divided into aluminum pans, stainless steel pans, and iron pans according to the base material. The characteristics of the aluminum pot are excellent heat distribution, the heat transfer effect is 16 times that of the stainless steel pot, and the pot body is lighter. However, the aluminum pan is not easy to clean, and the oil smoke is large when the oil is used for a long time. The characteristic of stainless steel pots is that the heat distribution is not good, and it is easy to generate hot spots and burn food. Stainless st...
