Problems solved by technology

Polytetrafluoroethylene can withstand high temperatures of 400 degrees, but its chemical properties begin to become unstable when it exceeds 200 degrees. It will immediately catch fire and burn when it exceeds 400 degrees, releasing hydrogen fluoride gas. The solution of hydrogen fluoride dissolved in water is called hydrofluoric acid, which is not only strong Corrosion (a large amount of hydrofluoric acid is used in the glass etching process), and it is highly toxic

Abstract

The invention belongs to the technical field of coating and in particular relates to diamond ceramic coating as well as a preparation method and application thereof. The diamond ceramic coating is prepared from silica sol, inorganic iron oxide red, ceramic silicon micro-powder, silicon carbide, diamond powder, absolute ethyl alcohol, de-ionized water, trimethylsilane, acetic acid and silicone oil;the preparation method of the diamond ceramic coating comprises the following steps: (1) weighing the raw materials according to the ratio and mixing; (2) carrying out sealed stirring for 3 to 4h under the conditions of 35 to 40 DEG C and 400 to 450rpm, so as to obtain the diamond ceramic coating. The diamond ceramic coating is applied to a non-stick frying pan coating layer; the diamond ceramiccoating is prepared from a primer layer, an intermediate paint layer which covers the primer layer and a finish paint layer which covers the intermediate paint layer; the primer layer is prepared fromthe diamond ceramic coating. The coating and the coating layer, provided by the invention, have the advantages of good thermal conductivity, high temperature resistance, friction resistance, high rigidity, no toxicity and no harms, energy source saving and beautiful appearance and good economic benefits; the method for preparing the diamond ceramic coating is simple and is easy to operate.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a diamond ceramic coating and its preparation method and application. Background technique [0002] At present, there are two types of non-stick pans on the market, one is Teflon non-stick pan, and the other is ceramic-coated non-stick pan. The main raw material of Teflon non-stick pan coating is polytetrafluoroethylene. According to the national mandatory standards, polytetrafluoroethylene is used as the main raw material, together with certain additives to form polytetrafluoroethylene coating, coated on the surface of aluminum, iron plate and other metals, sintered at high temperature, as a non-acid food container Anti-sticking coatings, the use temperature is limited to below 250 ℃. Polytetrafluoroethylene can withstand high temperatures of 400 degrees, but its chemical properties begin to become unstable when it exceeds 200 degrees. It will immediately catch fir...
