Embodiment 1

[0029] The preparation method of the antibacterial and wear-resistant composite non-stick coating of the present embodiment comprises the following steps:

[0030] Step S1: Put the metal pot body into the sand blasting machine, use silicon carbide ceramics as shot blasting, and perform sand blasting roughening treatment to form an uneven convex structure on the inner surface of the pot body, then degrease and clean it spare;

[0031] Step S2: In parts by weight, weigh 5 parts of nano-zinc powder, 10 parts of nano-alumina powder, 3 parts of ethanol and 0.5 part of polyethylene glycol, ball mill in a high-speed ball mill for 12 hours, sieve with a 300-mesh screen, and take Mix 20 parts of undersize with 1.5 parts of vinyltriethoxysilane and 35 parts of deionized water, then add 16 parts of zinc metal-organic framework and 1.5 parts of vinyltriethoxysilane in sequence, and continue to stir for 30 minutes. Coating on the internal surface of the metal pot in step S1, sending it in...

Abstract

The invention discloses a preparation method of an antibacterial and wear-resistant composite non-stick pan coating, which comprises the following steps: S1: performing sandblasting and roughening treatment on the metal pan body, and then degreasing and cleaning for standby; S2: applying nano-zinc powder , Nano-alumina powder and dispersing aid are evenly ball-milled, then evenly mixed with silane coupling agent and deionized water, then sequentially add zinc metal organic framework and silane coupling agent, continue to stir, and evenly coat on the inner surface of the metal pot , after high-temperature calcination, the non-stick pan bottom layer is obtained; S3: Weigh a certain amount of silane-modified nano-silica sol; then add additives and suspending agents, stir and mix evenly, and then apply it on the bottom layer, and then perform UV curing and drying successively. Get a composite ceramic nonstick coating. The non-stick pan ceramic coating prepared by the invention solves the problems of poor antibacterial performance, easy cracking, poor wear resistance and short service life of the existing non-stick pan coating, and meets the long-term safe and healthy use requirements of the non-stick pan coating .

Description

technical field [0001] The invention relates to the technical field of non-stick pan coatings, in particular to an antibacterial and wear-resistant composite non-stick pan coating and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people pay more attention to food safety and healthy diet. Non-stick pans are gradually replacing traditional iron pans due to their excellent properties such as easy cleaning, no food sticking to the pan body, and the ability to minimize oil fume. According to the different non-stick pan coating materials, it can be divided into organic coating and inorganic coating. Regardless of organic coating or inorganic coating, if the non-stick pan is used for a long time or after micro-cracks appear after improper use, bacteria will easily grow on the surface of the pan, which will seriously affect food safety and human health. [0003] There are many reasons for the microcracks of the coati...
