Problems solved by technology

[0005] Most of the existing non-stick pan products use a single Teflon (polytetrafluoroethylene) as the non-stick coating. The non-stick coating has poor scratch resistance and cannot be cooked with a shovel. The high temperature resistance also needs to be improved.

Abstract

The invention relates to the field of surface treatment of cookware, in particular to a method for preparing a wear-resistant non-stick pan coating. By weight, 100 parts of water, 20-40 parts of polytetrafluoroethylene, 24-40 parts of polyethersulfone resin, 6-12 parts of polyetheretherketone, 2-5 parts of polymethylvinylsiloxane and 0.003-0.1 part of an alane N,N-dimethylethylamine complex are heated to 450-550 DEG C and stirred for 5-10 h, then 1-3 parts of nano graphene oxide, 2-4 parts of carbon monofluoride, 2-4 parts of mica powder and 0.5-1 part of distearyloxyisopropoxyaluminate are added, stirring is carried out for 2-5 h, then 1.5-3.5 parts of a coating reinforcing agent is added, and a wear-resistant non-stick pan paint is obtained; then the obtained wear-resistant non-stick panpaint is applied to the inner surface of a pretreated metal pan, then the metal pan is placed in a constant-temperature drying oven, drying is carried out for 15-30 min at 250-350 DEG C, and the wear-resistant non-stick pan is obtained.

Description

technical field [0001] The invention relates to the field of surface treatment of cookware, in particular to a method for preparing a wear-resistant non-stick pan coating. Background technique [0002] The main effect of the non-stick pan is that it is not easy to stick to the bottom of the pan when using its cooking ingredients. Inconvenience caused by hard-to-clean burnt substances when cooking utensils. Therefore, the advent of non-stick pans has brought great convenience to people's lives, and people no longer have to worry about the problem of easy burning and sticking to the pan when cooking food. The non-stick performance of the non-stick pan has nothing to do with the shape of the pot. The non-stick performance mainly comes from the non-stick coating coated on the inner surface of the pot. [0003] CN108836099A discloses a non-stick pan, which relates to the technical field of small household appliances. The non-stick pan provided by the invention includes a pan b...
