Antibacterial corrosion-resistant ceramic coating of non-stick pan and preparation method of coating

Abstract

The invention relates to an antibacterial corrosion-resistant ceramic coating of a non-stick pan and a preparation method of the coating, and belongs to the technical field of ceramic machining. The antibacterial corrosion-resistant ceramic coating comprises the components in parts by weight as follows: 35-40 parts of silicon oxide sol, 5-9 parts of aluminum oxide sol, 1-3 parts of zirconium oxide sol, 5-8 parts of a water soluble polyester modified epoxy resin, 1-3 parts of black iron oxide, 5-8 parts of spherical ceramic micro powder, 8-12 parts of absolute ethyl alcohol, 1-3 parts of silver nitrate, 1-3 parts of aluminum nitrate, 1-3 parts of and fluoride silicone oil and 10-15 parts of deionized water. The preparation method comprises the steps as follows: the materials are mixed according toin the ratio, stirred for 4-6 h in a sealing manner at a temperature of 35-42 DEG C and a rotating speed of 300-350 rpm (revolutions per minute), and then calcinated at a high temperature of 300-350 DEG C; and composite ceramic material powder is composited. The coating of the non-stick pan has good mechanical property, is high in strength, high-temperature-resistant, abrasion-resistant and scratch-resistant, and has an antibacterial function; and the preparation technology is simple, and the coating is non-toxic and harmless to the environment.

Description

technical field [0001] The invention relates to a ceramic coating, in particular to a non-stick pan antibacterial and wear-resistant ceramic coating and a preparation method thereof, belonging to the technical field of ceramic production and processing. Background technique [0002] With the development of world culture, in addition to some traditional iron pans and other cooking utensils, non-stick pans have also begun to enter Chinese families. The reason why non-stick pans are not sticky is because of the layer of "Teflon" coating on the bottom of the pan. This substance is the general term for fluorine-containing resins, including polytetrafluoroethylene, polyperfluoroethylene propylene and various fluorine-containing copolymers. Because these compounds have the advantages of high temperature resistance, low temperature resistance, self-lubrication, and chemical stability, they are widely used. Used in non-stick cookware, waterproof and breathable materials (such as wat...

201210127882.9 discloses a high-temperature-resistant ceramic coating for non-stick cookware and its preparation method. The main components of the coating are silica sol, alumina sol, zirconia sol, methyltriethoxysilane, dimethyldimethylsilane Oxysilane, etc., this patent utilizes the high temperature resistance stability of the -Si-O- bond to ensure the excellent performance of the high temperature resistance of the coating, but its preparation uses isopropanol, which has certain damage to the environment. At the same time, the coating's The wear resistance is poor, and it has no antibacterial effect, and the function is single, which cannot meet the needs of the market
