A kind of preparation method of water-absorbing anti-fog glass

Abstract

The invention relates to a water-absorbing anti-fog glass manufacturing method. The method includes the steps that step 1, after tetraethoxysilane, organic solvent and distilled water are mixed, a basic catalyst is added into the mixture at constant speed under the ultrasonication for reaction, and a nano-silica sol is obtained after a period of ultrasonication; step 2, a surfactant is added into the nano-silica sol obtained in the first step, and the mixture of the surfactant and the nano-silica sol is stirred to be uniform to obtain a nano-silica solvent mixed solution; step 3, resin containing water absorption groups and resin capable of cross-linking and solidifying are added into the nano-silica solvent mixed solution obtained in the second step and the mixture is stirred to be uniform, a curing agent and a flatting agent are added into the mixture and the mixture is stirred to be uniform, and a water-absorbing anti-fog solution is obtained; step 4, the surface of automobile glass is pretreated, degreased and polished physically, washed with tap water and distilled water respectively and dried; step 5, the clean and dry glass surface is plated with a membrane of the water-absorbing anti-fog solution obtained in the third step, and automobile glass with the anti-fog function is obtained.

Description

technical field [0001] The invention belongs to the technical field of automobile glass, in particular to the application field of anti-fog technology of automobile glass, in particular to a preparation method of water-absorbing anti-fog glass. Background technique [0002] In winter or summer rainy days, there is a large temperature difference between the inside and outside of the car. When the temperature of the inner surface of the glass reaches the dew point temperature, water vapor will condense on the glass surface, forming densely packed small water droplets. Due to the existence of these tiny water droplets, light will be refracted and reflected when passing through the glass, which will significantly reduce the light transmittance of the glass, seriously affect the clarity of the driver's sight, and easily lead to traffic accidents. According to professional statistical comparison, the impact of the driver's sight will increase the traffic accident rate by 5 times. ...
