Abstract

The invention belongs to the surface modification field of vehicle glass, and provides hydrophobic solution, a manufacturing method for hydrophobic glass for a vehicle and the hydrophobic glass for the vehicle. The hydrophobic solution consists of silane, silicate ester, alcohol, acid catalyst and stabilizing agent, wherein the number of carbon atoms of the silane is 10 to 18. The manufacturing method comprises the following steps of: coating the hydrophobic solution as claim 1 on the surface of a piece of glass to form a hydrophobic film layer, performing physical and chemical reaction on the glass, and thermally treating the glass to obtain the hydrophobic glass. The hydrophobic glass for the vehicle comprises the glass, the hydrophobic film layer formed by the hydrophobic solution is coated on the outer surface of the glass, and the contact angle of the hydrophobic film layer is more than 90 degrees. The silicate ester and the long-chain silane produce hydrolysis reaction under thecondition of acid catalysis, and the generated hydrolysis product and a SiOH group on the surface of the fresh glass produce condensation polymerization reaction to form a firm silicon-oxygen chemical bond combination so as to improve the adhesion of the hydrophobic film layer and the glass.

Description

technical field [0001] The invention belongs to the field of surface modification of vehicle glass, in particular to a hydrophobic solution, hydrophobic glass for vehicles and a manufacturing method thereof. Background technique [0002] When the vehicle is driving at high speed in rainy days, rainwater will adhere to the surface of the windshield or rearview mirror glass of the car, which will seriously affect the driver's sight. Even if the wiper is used, there will be many dead spots. And just can't do anything about the front door glass and the second door glass wiper on the side. According to experts, when we need to make some very important decisions while driving, our eyes provide about 90% of the information reference. 65% of the drivers feel the difficulty of driving in the rain during the day, and 82% of the people feel the difficulty of driving in the rainy day at night. On rainy days, muddy and slippery road surfaces and very low visibility lead to a high incid...
