Embodiment 1

[0028] The preparation method of the wear-resistant ceramic coating non-stick pan of the present embodiment, it comprises the following steps:

[0029] 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;

[0030] Step S2: In parts by weight, weigh 45 parts of boron-modified silica sol and 30 parts of silane-modified nano-titanium sol; Bentonite, stir and mix evenly to obtain a coating slurry; the boron-modified silica sol is boride-modified acidic silica sol, and its pH is 3.5; the silane-modified nano-titanium sol is nano-scale titanium oxide dispersed with oxalic acid The sol is used as a raw material, and then the vinyl chloride silane is hydrolyzed and co-condensed with the titanium oxide sol to obtain it; the pH of the silane-modified nano-titanium sol is 3.7, a...

Embodiment 2

[0039] The preparation method of the wear-resistant ceramic coating non-stick pan of the present embodiment, it comprises the following steps:

[0040] Step S1: Put the metal pot body into the sand blasting machine, use stainless steel beads as shot blasting, and perform sandblasting roughening treatment to form an uneven raised structure on the inner surface of the pot body, then perform degreasing treatment, and clean it for later use ;

[0041] Step S2: In parts by weight, weigh 55 parts of boron-modified silica sol and 40 parts of silane-modified nano-titanium sol; and add 12 parts of long-chain olefin-substituted cage polysilsesquioxane and 3 parts of organobentonite , stir and mix evenly to obtain a coating slurry; the boron-modified silica sol is boride-modified acidic silica sol, and its pH is 4; the silane-modified nano-titanium sol is nano-scale oxidation Titanium sol is used as a raw material, and then obtained after co-condensation with the titanium oxide sol afte...

Embodiment 3

[0050] The preparation method of the wear-resistant ceramic coating non-stick pan of the present embodiment, it comprises the following steps:

[0051] 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;

[0052] Step S2: In parts by weight, weigh 65 parts of boron-modified silica sol and 50 parts of silane-modified nano-titanium sol; Bentonite and 1.5 parts of organobentonite are stirred and mixed evenly to obtain a coating slurry; the boron-modified silica sol is boride-modified acidic silica sol, and its pH is 4.5; the silane-modified nano-titanium sol is prepared with formic acid The nano-scale titanium oxide sol dispersed with acetic acid is used as raw material, and then obtained after co-condensation with the titanium oxide sol after hydrolysis of vinyl chlori...

Abstract

The invention discloses a preparation method of a non-stick pan with a wear-resistant ceramic coating, which comprises the following steps: step S1: performing sandblasting and roughening treatment on the metal pan body to form an uneven convex structure on the inner surface of the pan, and then performing Degreasing treatment and cleaning for later use; step S2: by weight, respectively weigh 45-65 parts of boron-modified silica sol and 30-50 parts of silane-modified nano-titanium sol; and add 10-15 parts of additives and 1.5 ~4.5 parts of suspending agent, stir and mix evenly to obtain coating slurry; step S3: coat the coating slurry obtained in step S2 on the inner surface of the pot in step S1, first use UV curing, and then quickly dry to obtain The wear-resistant ceramic coating is non-stick. The non-stick pan ceramic coating prepared by the invention not only has the characteristics of high-temperature boiling resistance and anti-sticking, but also has the advantages of anti-cracking, antibacterial and wear-resistant, and meets the long-term safe use requirements of the non-stick pan coating.

Description

technical field [0001] The invention relates to the technical field of non-stick pan coating, in particular to a method for preparing a non-stick pan with wear-resistant ceramic coating. 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, non-stick pans, and the ability to minimize oily fume. According to the different non-stick pan coating materials, it can be divided into organic coatings and inorganic coatings. Organic non-stick coatings are mainly polyfluororesin non-stick coatings, relying on their strong hydrophobicity and low friction coefficient to achieve non-stick food. However, the organic polytetrafluoroethylene coating has poor bonding force and strength with the non-stick pan metal substrate, which is easy to fall off and damage, and will soften during cook...
