Abstract

The invention belongs to the technical field of glass surface hydrophobic treatment, and in particular relates to a highly transparent glass hydrophobic agent and a preparation method thereof. A water-repellent agent for high light-transmitting glass, prepared from the following raw materials in parts by weight: 100 parts of dimethylcyclosiloxane, 20-50 parts of phenylsiloxane, 5-10 parts of silane coupling agent 0.1-1 part of basic catalyst, 5-100 parts of non-ionic surfactant, 10-90 parts of solvent, can form a layer of transparent hydrophobic film on the glass surface, water droplets form water droplets on the glass surface, and the contact angle is as high as 110°, which greatly speeds up the falling speed of water droplets, and can realize automatic rolling without leaving traces, thus solving the problem of unclear vision.

Description

technical field [0001] The invention belongs to the technical field of glass surface hydrophobic treatment, and in particular relates to a highly transparent glass hydrophobic agent and a preparation method thereof. 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. [0003] There are glass hydrophobic agents for daily car maintenance on the market, but they are generally short-acting hydrophobic agents with weak sand and dust resistance, and the glass surface needs to be cleaned to achieve a good hydrophobic effect. The use conditions are relatively harsh. The scope is limited. Contents of the...
