Abstract

The invention relates to the field of antibacterial non-stick pans, and discloses an antibacterial non-stick material, a preparation method thereof and an antibacterial non-stick pan. The method comprises the steps that (1) alumina powder is used for conducting thermal spraying on the surface of a base material to form an alumina layer; (2) non-stick coating a is sprayed on the alumina layer to form a priming coat; and (3) antibacterial coating is sprayed on the priming coat to form an antibacterial finishing coat, and an antibacterial non-stick aluminum material is obtained, wherein the antibacterial coating is composition containing an antibacterial material and non-stick coating b, and the antibacterial material is selected from antibacterial agents containing at least one of silver, zinc, copper and zinc oxide; taking the weight of the antibacterial coating as the standard, the antibacterial material in the antibacterial coating comprises, by weight, 0.8-10% of Ag, Zn or Cu; and the base material is a metal base material, a ceramic base material or a carbon base material. The antibacterial non-stick material has the characteristics of high hardness, high adhesion, abrasion resistance, corrosion resistance and high antibacterial rate and can meet the needs of preparation of the antibacterial non-stick pan.

Description

technical field [0001] The invention relates to the field of antibacterial non-stick cookware, in particular to an antibacterial non-stick material, a preparation method thereof, and an antibacterial non-stick cookware. Background technique [0002] In today's society, with the continuous improvement of people's living standards, it is difficult for kitchenware products, especially non-stick coatings with a single function in pots, to meet consumers' requirements for diversified product functions. [0003] However, in the prior art, problems such as insufficient adhesion between the non-stick coating and the substrate, poor wear resistance, and short service life have been perplexing consumers and manufacturers. Especially after the rice cooker has a reservation function, during the reservation period, the food will provide a favorable environment for the growth of bacteria under the action of moisture. [0004] Therefore, it is necessary to overcome the problems of the pot...
