A kind of non-stick pan coating with graphene material and preparation method thereof

Abstract

The invention discloses a non-stick pan coating with graphene material. The non-stick pan coating is composed of a bottom layer and a surface layer; the bottom layer is composed of the following parts by weight of raw materials: 50-90 parts of polytetrafluoroethylene Ethylene / polysulfone blend, 0.5-2 parts modified graphene oxide, 1-5 parts thermochromic pigments, 0.8-1.2 parts modified silicon carbide whiskers, 1.5-3 parts additives and 15-35 parts deionized water; the surface layer is composed of the following raw materials in parts by weight: 35-75 parts of polytetrafluoroethylene resin, 1.5-5 parts of modified calcium carbonate whiskers, 3-8 parts of fatty alcohol polyoxyethylene ether ammonium sulfate, 5 parts of ~10 parts maleic anhydride and 35-60 parts deionized water. Through the reasonable compatibility of different raw material components of the bottom layer and the surface layer, the prepared non-stick pan coating has a better over-temperature prompting function, is more conducive to the control of the cooking temperature, and has excellent high temperature resistance and wear resistance. Extends the life of non-stick pans.

Description

technical field [0001] The invention relates to the technical field of non-stick pan coating, in particular to a non-stick pan coating with graphene material and a preparation method thereof. Background technique [0002] According to different functions, non-stick pans can be divided into cooking pans, frying pans, wok pans, and milk pans. According to the non-stick coating system on the inner surface, they can be divided into one-layer system, two-layer system and three-layer system pan. A one-layer system refers to a non-stick layer composed of a single paint; a two-layer system refers to a non-stick layer composed of two types of paint, the bottom layer and a top layer; Non-stick layer. [0003] The over-temperature reminder function of the existing non-stick pan coating has poor effect. When people are cooking, they often cannot clearly know the temperature of the food on the non-stick pan coating, and it is difficult to grasp the cooking heat and cooking time. Cookin...

Problems solved by technology

[0005] In view of the above deficiencies in the prior art, the technical problem to be solved in the present invention is to provide a non-stick pan with graphene material for the lack of its over-temperature prompt function and the problem of poor high temperature resistance and wear resistance. The pan coating and its preparation method improve the high temperature and wear resistance of the non-stick pan, and prevent the occurrence of problems such as coating cracks, shedding, and pits caused by high-temperature corrosion and oxidation during the use of the non-stick pan. At the same time, it has many advantages such as excellent over-temperature prompt function and long service life, which is more conducive to the control of cooking heat
