preparation example Construction

[0028] The preparation of the coating composition only needs to uniformly mix the silicone resin, the fluorine-containing surfactant and the coupling agent in proportion.

[0029] The paint provided by the invention contains an organic solvent and the paint composition of the invention.

[0030] The organic solvent may be one or more of aliphatic hydrocarbon solvents, aromatic hydrocarbon solvents, alcohols and ester solvents. For example, it may be one or more of n-octane, n-heptane, toluene, xylene, n-butanol, isobutanol, ethyl acetate, and butyl acetate. The present invention preferably uses n-octane and / or n-heptane. When the organic solvent is a mixed solvent, the content of each organic solvent can be in any ratio. In the coating, the weight of the organic solvent is 4-10 times the weight of the coating composition.

[0031] The preparation method of the coating only needs to mix the coating composition and the organic solvent and stir evenly, and the mixing can be pe...

Embodiment 1

[0040] This example illustrates the coating composition of the present invention, coatings containing the composition, and coatings formed from the coating.

[0041] With 93 grams of silicone resin (SR2410 type of U.S. DOW CORNING company), 2 grams of fluorosurfactant (Zonyl 8857A type of U.S. DuPont Company), 5 grams of silane coupling agent (Z-6040 type of U.S. DOW CORNING company) Mix evenly to obtain a coating composition. In the composition, the content of the silicone resin is 93% by weight, the content of the fluorine-containing surfactant is 2% by weight, and the content of the silane coupling agent is 5% by weight. Add the coating composition into 600 g of mixed solvent (the weight ratio of n-octane and n-heptane is 1:1), and stir evenly to obtain the coating. Then the stainless steel base material (Dongguan Rongjia Stainless Steel Raw Material Company, 316 type) was soaked in the coating for 2 minutes and then taken out, left to stand for 0.5 hour in a clean environm...

Embodiment 2

[0043] This example illustrates the coating composition of the present invention, coatings containing the composition, and coatings formed from the coating.

[0044] With 96 grams of silicone resin (SR2410 type of U.S. DOW CORNING company), 1 gram of fluorosurfactant (Zonyl 8857A type of U.S. DuPont Company), 3 grams of silane coupling agent (Z-6040 type of U.S. DOW CORNING company) Mix evenly to obtain a coating composition. In the composition, the content of the silicone resin is 96% by weight, the content of the fluorine-containing surfactant is 1% by weight, and the content of the silane coupling agent is 3% by weight. Add the coating composition into 600 g of mixed solvent (the weight ratio of n-octane and n-heptane is 1:1), and stir evenly to obtain the coating. Then the stainless steel base material (Dongguan Rongjia Stainless Steel Raw Material Company, 316 type) was soaked in the coating for 2 minutes and then taken out, left to stand for 0.5 hour in a clean environme...

Abstract

The invention provides a painting combination which comprises silicon resin, fluorine-containing surfactant and coupling agent. Through the paint that is provided by the invention and painted on substrates to format a coating layer, the fingerprint blot resistance of the substrates can be improved greatly. For example, the fingerprint blot resistance of the material containing the coating layer of the invention is all above good.

Description

technical field [0001] The present invention relates to a coating composition. Background technique [0002] With the continuous improvement of the quality of life, in the field of electronic equipment such as mobile phones, notebook computers, mobile storage, and household appliances, consumers not only require excellent operating performance, but also have higher and higher requirements for product appearance. In addition to the general requirements for the surface of the commodity casing to have excellent properties such as wear resistance, corrosion resistance, and scratch resistance, it is further required that the surface of the commodity casing has excellent anti-fingerprint performance. The fingerprints mean that dust, water stains, grease and other stains easily contaminate the surface of the shell during the use of the product, leaving many traces that are not easy to clean after being touched by hands. Such fingerprints are difficult to remove even by wiping, and...
