Abstract

The invention belongs to the technical field of glass surface treatment, in particular to a self-cleaning glass hydrophobic agent. The self-cleaning glass hydrophobic agent includes A component and B component. In parts by weight, the A component is prepared from the following raw materials: 100 parts of dimethylcyclosiloxane, containing 20 parts of phenylsiloxane ~50 parts, 5~10 parts of silane coupling agent, 0.1~10 parts of basic catalyst, 5~40 parts of surfactant, 10~90 parts of solvent; the B component is prepared from the following raw materials: organic fluoride 80 parts, 4-15 parts of silane coupling agent, 10-30 parts of dimethyl cyclosiloxane, 10-20 parts of phenylsiloxane, 0.1-10 parts of basic catalyst, 5-40 parts of surfactant parts, 10-90 parts of solvent, and 1-20 parts of nano-titanium oxide. After being used on automobile glass, water droplets can form water droplets on the glass surface, and its contact angle can be as high as 125°, which can automatically roll off without leaving traces, thus solving the problem of unclear vision.

Description

technical field [0001] The invention belongs to the technical field of glass surface treatment, in particular to a self-cleaning glass hydrophobic agent. Background technique [0002] The surface of ordinary glass is a hydrophilic surface. When water droplets spread on the glass, the light transmission of the glass will deteriorate. The blurring of car windshields, side windshields, and front and rear view mirrors is an important cause of traffic accidents. In the case of rain or high humidity, attached droplets will form on the surface of the car glass and affect the line of sight. Contents of the invention [0003] In order to solve the above problems, the present invention provides a self-cleaning glass hydrophobic agent, water droplets can form water droplets on the glass surface, and its contact angle can be as high as 125°, which can automatically roll off without leaving traces, thereby solving the problem of unclear vision question. [0004] The present invention...
