Problems solved by technology

After some hydrophilic polymers absorb water, not only the anti-fog performance is reduced, but also the film is cracked due to swelling and softening, so it must be chemically cross-linked

Embodiment 1

[0066] In 120g ethylene glycol monomethyl ether, add 18g omega-hydroxyl terminal dodecyl alcohol ethoxyl group (n=4) methacrylate, 6g methacrylate (2-hydroxyethyl) ester, 6g methacrylic acid and 0.15g of benzoyl peroxide, stir to dissolve completely, polymerize at 60C for 6 hours. After cooling, add 4.5g of tributoxymethyl melamine, 0.3g of p-toluenesulfonic acid and 0.6g of leveling agent, stir well and set aside.

[0067] Add 0.3g of p-toluenesulfonic acid to the above coating and mix well. The coating composition was sprayed onto the surface of the polycarbonate plate, pre-baked in an oven at 50°C for 0.5 hour, and then cured at 120°C for 1 hour to cure the coating.

Abstract

An antifog hydrophilic high-molecular paint is prepared from hydrophilic high-molecular material prepared from non-ionic surfactant, (methyl) acrylate, N-vinylpyrrolidone, (methyl) acrylic acid and/or (hydroxy contained (methyl) acrylate through polymerizing, solidifying agent and solidifying promoter. Its advantages are low cost, high adhesion and long service life.

Description

technical field [0001] The invention relates to a hydrophilic polymer anti-fog coating and a preparation method thereof. Background technique [0002] The accumulation of fog on the transparent substrate has attracted more and more people's attention. It may cause inconvenience to people's life, or affect the normal operation of vehicles, and then affect industrial production and economic activities. At present, the research on this kind of anti-fog materials is increasing. In the past, simple anti-fog mirrors usually installed an electric heater on the back of the mirror to drive away the foggy moisture. If the fog cannot be effectively controlled, it will have very adverse consequences. [0003] Zhang Chunxue and others reported that the coating composed of MMA, BMA, HEMA and a small amount of crosslinking agent, N, N-methylene dienamide polymerization has a good anti-fog effect. Li Xuefeng et al added a small amount of crosslinking agent (hexamethoxymethylmelamine, eth...
