Anti-fouling wear-resisting transparent fluorine-silicone polymer material and preparation method thereof

Abstract

The invention relates to an anti-fouling wear-resisting transparent fluorine-silicone polymer material and a preparation method thereof. The fluorine-silicone polymer material contains perfluoroalkyl and silicon-oxygen alkyl. The preparation method comprises the steps of adding an unsaturated monomer containing fluorine, an unsaturated siloxane monomer, a reaction solvent, an initiator, auxiliaries and bactericide into a high pressure reactor; and under the protection of nitrogen, heating and warming, controlling the pressure of the reactor, adjusting stirring, carrying out constant-temperature stirring reaction for 8-16 hours, and then fast cooling to room temperature. The fluorine-silicone polymer material can be coated on the surface of substrates such as glass, metal, plastic and the like in modes of spray coating, roll coating, wiping and the like to achieve the effectively waterproof, oil-proof, anti-fouling and wear-resisting effects.

Description

[0003] In recent years, the preparation of hydrophobic, oleophobic, antifoulin...

AI Technical Summary

Problems solved by technology

[0006] At present, the production of fluorosilicon materials has spread all over the country, but the friction resistance of domestically produced fluorosilicon products is relatively low. After a certain degree of wear, the waterproof and oil-proof performance is seriously reduced; The contact angle of the hydrophobic coating to water will decrease with the prolongation of outdoor use time, and the hydrophobicity will decrease

This is mainly caused by the adsorption and accumulation of dust and organic pollutants in the air on the solid surface; most of the existing antifouling fluorosilicon polymer materials are produced by indirect methods, because there are many intermediate products, the synthesis route is complicated, and the products are not easy to purify. And the purpose is single, the enterprise device is a closed chain, so there are more prominent pollution and equipment corrosion problems, the cost is relatively high, and the product performance is low

With the rapid development of the market and the tightening of environmental protection policies, the existing anti-fouling fluorosilicon polymer materials can no longer adapt to the development of fluorosilicon polymer materials.
