Embodiment 1

[0022] Embodiment 1: This embodiment provides a method for preparing an anti-fog coating, including the following steps:

[0023] The surface of the transparent glass was ultrasonically cleaned with acetone and water, then physically polished, cleaned with water, and then dried for later use.

[0024] 2.5g of maleic anhydride grafted polyethylene, 5g of nano silica particle solution treated with silane coupling agent, and 0.5g of concentrated sulfuric acid are dissolved in 500mL of a mixed solution of acetone and tetrahydrofuran (volume ratio 1:2), Stir evenly to obtain a mixed solution. The mixed solution was spin-coated on the glass surface that had been processed in the previous step at a rotation speed of 2000 rpm. Then under vacuum conditions, heating at 95°C for 12 hours and then taking it out for later use.

Abstract

The present invention relates to an anti-fog coating and its manufacturing method and anti-fog glass, comprising the following steps: Step 1, firstly pretreat the surface of the transparent material, use an organic solvent A for degreasing treatment, then physically polish, and then sequentially separate Rinse with tap water and distilled water and dry; Step 2, the following units are parts by mass, with 5-10 parts of maleic anhydride grafted polyethylene, 10-40 parts of inorganic nanomaterials and 1-5 parts of catalyst processed by silane coupling agent Mixed in organic reagent B, coated on the surface of the transparent material treated in step 1, and then heat-treated the transparent material under vacuum conditions; step 3, the following units are parts by mass, the polymer containing hydrophilic functional groups 8-10 parts of the polymer and 2-6 parts of the surfactant are dissolved in water, stirred evenly, and then used to coat the surface of the transparent material treated in step 2, and heat-treated under vacuum conditions to obtain the surface of the transparent material. Effective anti-fog coating.

Description

Technical field [0001] The invention relates to the field of anti-fog technology, in particular to a polymer anti-fog coating, a manufacturing method thereof, and anti-fog glass. Background technique [0002] In our daily life, we often encounter the phenomenon that transparent materials condense and dew due to the temperature difference in the environment, forming dense droplets of water. 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, and bring serious consequences. For example, the fogging of the car windows will affect the driver's sight, and the fogging of the doctor's surgical mask will interfere with the operation. [0003] Currently widely used anti-fogging products with surfactants as the main component, the anti-fogging time of the coating is very short, generally within 10-15 days, and with the incre...
