Problems solved by technology

At present, in foreign markets, high-end antifouling agents produced by companies such as Dow Corning in the United States have been widely used in electronic touch screens and flat panel displays, but there are currently no satisfactory products in China. In addition, the production process of these foreign products is relatively complicated and the price is high. , so there is an urgent need in the market for an anti-fouling and easy-cleaning agent that is cheap, easy to produce and use, and has a good effect

Embodiment 1

[0016] Dissolve 50g of perfluorooctyl ethyl acrylate and 2g of γ-methacryloxypropylmethyldiethoxysilane in 150ml of 2-butanone, add 0.2g of AIBN, and keep the reaction at 80°C for 4 hours. The solvent of the product after the reaction is completed, and the random silicon-fluorine copolymer A is obtained. Then, add 5000g of FF31 solvent into the silicon-fluorine copolymer A, stir until uniform, and obtain the antifouling and easy-cleaning agent. The anti-fouling and easy-cleaning agent was sprayed on the surface of the glass slide, and after standing at ambient temperature for 8 hours, the water contact angle reached 121.3°, and the hexadecane contact angle reached 82.6°.

Embodiment 2

[0018] Dissolve 50g of perfluorohexyl ethyl acrylate and 1g of γ-methacryloxypropylmethyldiethoxysilane in 150ml of 2-butanone, add 0.3g of AIBN, and incubate at 75°C for 5 hours. The solvent of the finished product is recycled to obtain the random silicon-fluorine copolymer B. Then add 10000g of FF31 solvent to the silicon-fluorine copolymer B, and stir until uniform to obtain the antifouling and easy-cleaning agent. The anti-fouling and easy-cleaning agent was sprayed on the surface of the glass slide, and after standing at ambient temperature for 8 hours, the water contact angle reached 119.6°, and the hexadecane contact angle reached 83.2°.

Embodiment 3

[0020] Dissolve 50g of perfluorobutyl ethyl acrylate and 2g of γ-methacryloxypropylmethyldiethoxysilane in 150ml of 2-butanone, add 0.3g of AIBN, and keep the reaction at 80°C for 4 hours. After the reaction is completed, the solvent is recovered to obtain the random silicon-fluorine copolymer C. Then, add 50000g of FF31 solvent into the silicon-fluorine copolymer C, stir until uniform, and obtain the antifouling and easy-cleaning agent. The anti-fouling and easy-cleaning agent was sprayed on the surface of the glass slide, and after standing at ambient temperature for 8 hours, the water contact angle reached 117.4°, and the hexadecane contact angle reached 81.5°.

Abstract

The invention provides a silicon and fluorine-containing antifouling easy-cleaning agent which is only composed of a silicon-fluorine copolymer and an FF31 type perfluorocarbon cyclic ether mixture solvent, wherein the silicon-fluorine copolymer is prepared through conventional solution type free radical polymerization by taking gamma-methylacrylyloxypropylmethylethoxy silane and perfluor C4-C18 alkyl acrylate as copolymerization monomers; the raw materials are simple, easily available and low in price, and the production process is mature and reliable; moreover, a finished product of the antifouling easy-cleaning agent is simple to use and low in price; after firm forming and curing, the antifouling easy-cleaning agent has good water/oil resistance and is not contaminated easily; a film layer has high strength and is not easy to wipe; the antifouling easy-cleaning agent can be widely applied to the surface of a glass substrate, a ceramic substrate or a plastic substrate, and is particularly applicable to the surface of an electronic touch screen.

Description

technical field [0001] The invention relates to an anti-fouling and easy-cleaning agent, in particular to an anti-fouling and easy-cleaning agent containing silicon and fluorine, which is suitable for the surface of an electronic touch screen and belongs to the field of fine chemicals. Background technique [0002] The surfaces of various appliances that are often touched, such as screens of high-end electronic equipment, kitchen utensils, glass curtain walls, and various sanitary ware, are easily stained by fingerprints, skin oils, sweat stains, and cosmetics. be removed or require strong cleaning agents to be removed, especially surfaces coated with anti-reflective coatings are more sensitive to dirt and fingerprints. These stains will not only affect the appearance, but may also cause certain safety problems. In response to the various problems mentioned above, researchers have designed an anti-fouling and easy-cleaning agent, which can be used not only for electronic to...
