Embodiment 1

[0046] Adopt the following production process to prepare the anti-blocking coating of the present invention that is used for monolayer: polyethersulfone (PES) micropowder (purchased from Caihong High-tech Materials (Laiyang) Co., Ltd.), polyphenylene sulfide (PPS) resin of following weight portion (purchased from DAINIPPON Ink and chemicals, Inc, Tokyo, Japan), titanium dioxide (Shanghai Jiangfu White Pigment Products Co., Ltd., Japan R930#), deionized water, ketone alcohol ether amine mixed solvent (in volume ratio, N -Methylpyrrolidone: ethylene glycol: ether: dimethylacetamide (1:1:1:1) is put into the container according to the above ratio, and after dispersing with a high-speed disperser (800-960 rpm) for 30 minutes, Filter through a 200-400 mesh filter, then add polytetrafluoroethylene resin (Solvay (Shanghai) Co., Ltd., 538#) according to the following ratio, and stir at a low speed (60-100 rpm) for about 20 minutes to obtain this product. The anti-blocking coating descri...

Embodiment 2

[0049] Using the same method as in Preparation Example 1, the anti-blocking coating of the present invention used for coating the intermediate layer was prepared according to the following parts by weight. Wherein, the pigment is titanium blue pigment (HOLIDAY, UK, 5008#), the water is pure water, and the rest of the raw materials are the same as in Preparation Example 1.

[0050]

Embodiment 3

[0052] Using the same method as in Preparation Example 1, the anti-blocking coating of the present invention used for the surface layer of the coating was prepared according to the following parts by weight. Wherein, the pigment is titanium blue pigment (HOLIDAY, UK, 5008#), the water is pure water, and the rest of the raw materials are the same as in Preparation Example 1.

Abstract

The invention relates to an anti-adhesion paint which comprises polyether sulfone (PES), polyphenylene sulfide (PPS), anti-adhesion agent, pigment, water and solvent. Compared with the traditional waterborne PES paint, the coating formed by adopting the anti-adhesion paint has better performances such as corrosion resistance, wear resistance, hardness, adhesive force and non-viscosity. The paint can not only be singly coated to form the finished product, but also be used as any layer of the multilayer nonstick paint.

Description

technical field [0001] The invention relates to an anti-blocking coating. More specifically, the present invention relates to an anti-blocking coating for articles having anti-blocking requirements, especially cookware. Background technique [0002] The thermal fluidity of anti-blocking coatings, the corrosion resistance (including salt corrosion resistance, acid and alkali corrosion resistance) and wear resistance of the resulting coatings are important indicators of anti-blocking coatings. The anti-adhesion coatings used in the past are mainly polyimide (PI) and polyamide-imide (PAI) coatings. The coating formed by this coating has low hardness, poor wear resistance and poor corrosion resistance. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the inventors combined the respective characteristics of polyethersulfone (PES) and polyphenylene sulfide (PPS), and proposed a brand-new anti-blocking coating, which contains polyether...
