Problems solved by technology

[0002] Alkali resistance and wear resistance are one of the important indicators of non-stick pans. The non-stick pan coatings used in the past are mainly polyamide-imide coatings. This kind of coating is expensive, and the alkali resistance, hardness and wear resistance are not high enough.

Embodiment Construction

[0014] The coating is made from the following raw materials in proportion by weight:

[0015] A: Binder: Polyethersulfone superfine powder (PES) Solid content: 5%

[0016] B: Anti-sticking agent: polytetrafluoroethylene resin, solid content: 10%

[0017] C: Filler: color paste, solid content: 11%

[0018] D: ultrapure water content: 58%

[0019] E: Solvent: ketone alcohol ether mixed solvent Content: 16%

[0020] The polyethersulfone water-soluble coating includes the following production process: put polyethersulfone ultrafine powder (PES), color paste, ultrapure water, and solvent into the container in proportion, and disperse it at a high speed (800-960 rpm) After dispersing by machine for 30 minutes, filter through 200-400 mesh, then add polytetrafluoroethylene resin in proportion, and stir at low speed (60-100 rpm) for 20 minutes to obtain polyethersulfone water-soluble coating.

[0021] The alkali resistance of the polyethersulfone water-soluble coating is obviously ...

Abstract

The invention relates to the formulation and the preparation process of polyether sulfone (PES) solution coating. The PES solution coating contains PES ultra-fine particles, polyfluortetraethylene resin, color paste, ultrapure water and solvent. The preparation process of the PES solution coating comprises the steps of putting the PES ultra-fine particles, the color paste, the ultrapure water and the solvent into a container according to a certain proportion, dispersing the PES ultra-fine particles, the color paste, the ultrapure water and the solvent with a high-speed dispersing machine, adding the polyfluortetraethylene resin into the filtered mixture of the PES ultra-fine particles, the color paste, the ultrapure water and the solvent, and stirring the polyfluortetraethylene resin and the filtered mixture for about 20 minutes. The PES solution coating is cheap, has high alkali resistance and abrasion resistance, can be independently coated into a finished product, and can be used as double-layer fluororesin nonstick coating.

Description

technical field [0001] The invention relates to a formula and a production process of a polyethersulfone water-soluble paint. Background technique [0002] Alkali resistance and wear resistance are one of the important indicators of non-stick pans. The non-stick pan coatings used in the past are mainly polyamide-imide coatings. This coating is expensive, and its alkali resistance, hardness and abrasion resistance are not high enough. Contents of the invention [0003] The purpose of the present invention is to provide a non-stick pan coating with alkali resistance, high hardness and wear resistance, and low cost and price. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] The paint is made of the following raw materials in weight ratio: [0006] A: Binder: Polyethersulfone superfine powder (PES) Solid content: 3-20% [0007] B: Anti-sticking agent: polytetrafluoroethylene resin, solid content: 5-30% [0008] ...
