Abstract

The invention belongs to the technical field of surface treatment of glass and particularly relates to a self-cleaning glass water repellent agent. The self-cleaning glass water repellent agent comprises a component A and a component B, wherein the component A is prepared from the following raw materials in parts by weight: 100 parts of dimethylcyclosiloxane, 20-50 parts of phenyl siloxane, 5-10 parts of a silane coupling agent, 0.1-10 parts of a basic catalyst, 5-40 parts of a surfactant and 10-90 parts of a solvent; the component B is prepared from the following raw materials in parts by weight: 80 parts of organic fluorine, 4-15 parts of a silane coupling agent, 10-30 parts of dimethylcyclosiloxane, 10-20 parts of phenyl siloxane, 0.1-10 parts of a basic catalyst, 5-40 parts of a surfactant, 10-90 parts of a solvent and 1-20 parts of nano-titanium oxide. After the water repellent agent is used on glass of an automobile, water drops can form water beads on the surface of the glass, the contact angle of each of the water beads can be as high as 125 degrees, and the water beads can automatically fall off without leaving a trace, so that the problem of unclear sight is solved.

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...
