Abstract

The invention provides high-temperature-resistant and high-thermal-conductivity non-stick coating. The high-temperature-resistant and high-thermal-conductivity non-stick coating is prepared from raw materials including, by weight, 100-120 parts of aluminium sesquioxide / red phosphorus modified fluorine resin, 50-70 parts of polyphenylene sulfide, 50-70 parts of graphene, 30-50 parts of carbon fibers, 40-70 parts of polylactic acid, 20-30 parts of thermal conduction inorganic fillers, 10-20 parts of coupling agents and 20-30 parts of auxiliaries. The auxiliaries comprise leveling agents, defoaming agents, film-forming agents, antioxidants, preservatives and ceramic powder. The high-temperature-resistant and high-thermal-conductivity non-stick coating has the advantages that the raw materialsfor the prepared high-temperature-resistant and high-thermal-conductivity non-stick coating can come from wide sources, a method for manufacturing the high-temperature-resistant and high-thermal-conductivity non-stick coating is simple and controllable, coatings prepared from the high-temperature-resistant and high-thermal-conductivity non-stick coating can be used at the high temperatures of 400-500 DEG C for a long term without influence on the performance, and accordingly the high-temperature-resistant and high-thermal-conductivity non-stick coating has a broad application prospect.

Description

technical field [0001] The invention relates to the technical field of polymer coatings, in particular to a non-stick coating with high temperature resistance and high thermal conductivity. 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. Stainle...
