Embodiment 1

[0049] Preparation and measurement of embodiment 1 coating and coating layer thereof

[0050] The polyethersulfone ultrafine powder, polyphenylene sulfide resin, titanium dioxide pigment, deionized water, N-methylpyrrolidone: ethylene glycol: ether: dimethylacetamide is 1:1:1:1 ketone alcohol The mixed solvent of ether and amine is put into the container according to the ratio in the following table 1, and after dispersing for 30 minutes at 900 rpm with a high-speed disperser, it is filtered through a 400-mesh filter, and then added according to the ratio in the following table 1. Tetrafluoroethylene resin was stirred at a low speed of 100 rpm for 20 minutes to obtain an anti-blocking coating.

[0051] The paint is coated on the stainless steel substrate to form a dry film with a thickness of 70 μm, which is measured by the small force Vickers hardness test in the standard GB / T 4340.1-2009 Vickers hardness test for metallic materials Part I: Test method. Apply the following f...

Embodiment 2

[0059] Embodiment 2 screens the ratio of polyethersulfone and polyphenylene sulfide

[0060] In order to clarify whether the ratio of the accessories with 25% content of polyethersulfone and 35% content of polyphenylene sulfide is synergistic, continue to conduct further tests around the content value satisfying the synergistic formula, and prepare and test the coating by the method of Example 1 , the specific results are shown in Table 2:

[0061] Table 2 Screening the synergistic ratio of coating hardness for optimal polyethersulfone and polyphenylene sulfide content

[0062]

[0063]

[0064] Through the ratio screening of polyethersulfone and polyphenylene sulfide, it is proved that the content range of polyethersulfone is 22%≤x≤27%, and the content range of polyphenylene sulfide is 33%≤y≤36%. When the thickness of the coating layer is 70 μm, the effect is increased. In the case of this hardness, the dry film can meet the requirements of wear resistance and toughnes...

Abstract

The invention relates to an anti-adhesion coating with anti-scraping anti-damage performance. The anti-adhesion coating is characterized by being prepared from a mixture containing polyether sulfone and polyphenylene sulfide, wherein the anti-adhesion coating coats the surface of a metal medium so as to form a dry film with the thickness of 60-80 mu m; the Vickers hardness Hv5 of the dry film under a force of 5kg is 400-450kg / mm<2>; the polyether sulfone accounts for x% of the total weight of the coating, the polyphenylene sulfide accounts for y% of the total weight of the coating, values of x and y meet the inequalities that x is not more than 22 and not less than 27, and y is not more than 33 and not less than 36. The anti-adhesion coating is capable of realizing full complementation in rigidity performances of polyether sulfone and polyphenylene sulfide; the ratio of polyether sulfone to polyphenylene sulfide is adjusted according to rigidity requirements so as to ensure that the ingredients for improving the rigidity of the coating are synergistic, and the final rigidity can ensure that the anti-adhesion coating is anti-scraping anti-damage in daily use and has tenacity.

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] When the anti-adhesion coating is used in a food heating container, in order to avoid external force damage to the coating during the food heating process, the coating needs to ensure a certain hardness, and at the same time, in order to ensure the fluidity, anti-adhesion performance and wear resistance of the coating during coating Therefore, it is necessary for the coating to ensure a certain hardness and strength, which is the coating requirement for the coating container. [0003] In current coatings, different technologies are adopted according to different requirements of coating properties. For example, an anti-corrosion film is described in Chinese Patent Application No. 200910204980.6, which includes: 1-35% by weight of...
