Abstract

The invention provides an antibacterial ceramic coating layer for a non-stick pan and a preparation method thereof, and the non-stick pan. The antibacterial ceramic coating layer adopts the following raw materials: modified alumina, silicon nitride, silicon dioxide and / or titanium dioxide, titanium nitride, zirconium boride, chromium oxide, a modified zinc oxide antibacterial agent and magnesium dihydrogen phosphate. Compared with the prior art, the modified alumina is adopted, on one hand, the toughness of the coating layer is enhanced, on the other hand, the expansion coefficient of a ceramic film is improved and is closer to a metal substrate expansion coefficient, and a chipping phenomenon is improved to a certain extent. Secondly, the modified zinc oxide antibacterial agent has synergistic effect with zinc oxide, silicon dioxide and titanium dioxide, so that the coating layer has relatively high antibacterial properties; thirdly, chromium oxide, titanium nitride, zirconium boride and other components can increase the hardness and wear resistance of the coating layer through a dispersion strengthening mechanism. Therefore, the prepared coating layer has the advantages of high-temperature resistance, wear resistance, bacteria resistance, and excellent non-stick performance and adhesion power.

Description

technical field [0001] The invention relates to the technical field of chemical coatings, in particular to an antibacterial ceramic coating for a non-stick pan, a preparation method and a non-stick pan. Background technique [0002] At present, the wok pans made of aluminum and aluminum alloys on the market are often unevenly heated during use, resulting in excessive local temperature, oily smoke, uneven heat conduction, burnt and sticky pans, and excessive force It will scratch the passivation layer on the surface of the aluminum material, reduce the service life of the pot, and it will not be cleaned with little force. Therefore, it is necessary to use coating technology on the inner surface of the wok to achieve the purpose of non-stick. One of the commonly used coatings is fluorine-containing organic coating represented by Teflon. This coating has poor high temperature stability, short life, and high temperature decomposition products are harmful to the human body. So a...
