Abstract

A glass hydrophobic plating liquid consists of long-chain alkyl silane coupling agent, silicate alkyl ester, alcohol, inorganic acid catalyst and deionized water or distilled water. It can form a layer of hydrophobic membrane on vehicle glass and the temperature of its contacting angle can reach to 110íÒC. It is good for sight of driver.

Description

technical field [0001] The invention relates to a surface hydrophobic agent, more specifically, the invention relates to a glass hydrophobic coating solution. Background technique [0002] When driving in the rain, the water droplets attached to the windshield of the car glass often block the line of sight, even if the windshield has wipers, there will be many dead spots. Moreover, the glass on the rear windshield and car doors, especially the rearview mirror, not only has a lot of water droplets, but it is even more impossible to wipe it while driving. These are the key factors of unsafe driving in the rain. At present, there is no method that is simple and feasible and can perfectly solve the above problems. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art and provide a glass hydrophobic coating solution with strong hydrophobic effect. [0004] Each component and content (% by weight) of the glass ...
