Uniform heat-conducting non-stick pan coating and preparation method thereof

Abstract

The invention relates to the technical field of non-stick pan coatings, in particular to a uniform heat-conducting non-stick pan coating and a preparation method thereof. The coating is prepared from the following raw materials in parts by mass: 49 to 55 parts of silicon carbide, 30 to 50 parts of aluminum oxide ceramic powder, 100 to 130 parts of aluminum nitride, 20 to 30 parts of modified nano silicon nitride, 150 to 180 parts of saturated polyester resin, 100 to 130 parts of organic silicon resin and 1 to 3 parts of hydrogenated castor oil. The non-stick pan coating disclosed by the invention is good in heat resistance, excellent in wear resistance and impact resistance, extremely stable in performance, capable of keeping excellent performance even if being used for a long time in an extreme environment, and outstanding in practical value.

Description

technical field [0001] The invention relates to the technical field of non-stick pan coatings, in particular to a non-stick pan coating with uniform heat conduction and a preparation method thereof. Background technique [0002] The advent of "non-stick pans" has brought great convenience to people's lives. People no longer have to worry about accidentally burning meat when cooking, and fish fillets sticking to the wall of the pan when frying fish. Most of the current non-stick pans are coated with a layer of polytetrafluoroethylene on the inner surface of the pan body. This popular kitchen utensil is made of the excellent chemical properties, easy-to-clean performance and non-toxic performance of polytetrafluoroethylene. . However, as an organic polymer material, polytetrafluoroethylene (PTFE) has thermal conductivity and wear resistance under long-term high temperature and external force, which can easily shorten the service life of non-stick pan coatings, seriously threa...

AI Technical Summary

Problems solved by technology

However, as an organic polymer material, PTFE’s thermal conductivity and wear resistance can easily shorten the service life of the non-stick pan coating under long-term high temperature and external force, which seriously threatens food safety and people’s health.

[0003] Ceramic materials are commonly used in the coating of non-stick pans, but the main direction is to enhance the strength of the coating. Ceramic materials with high thermal conductivity oxides, nitrides, carbides, and borides are used in limited quantities in non-stick pans. further research

For example, the patent number is CN202010690462.6, a method for preparing a high-temperature and wear-resistant non-stick coating, which includes sandblasting and roughening the non-stick substrate, taking MOFs, additives and solvents, stirring and mixing evenly, adding fluorine Resin emulsion and fluorine-containing silane coupling agent, continue to stir, spray granulation to obtain a powder with a particle size of 1-10 μm to obtain a coating, but there are fewer types used, and the improvement of the performance of the coating in complex situations is limited. In the long-term Can cause the decline of coating thermal conductivity in use; Another example is a kind of non-stick coating of CN201610267894. Mica powder, amino resin, dispersant and solvent are mixed, ground, dispersed, and filtered to obtain a coating; however, the filler components used in the coating have not been effectively modified on the surface, which has limited impact on the structural strength and thermal conductivity of the coating material
