Abstract

The invention belongs to the technical field of hydrophobic treatment on surface of glass, and particularly relates to a high-transparency glass hydrophobic agent and a preparation method thereof. Thehigh-transparency glass hydrophobic agent is prepared from the following raw materials in parts by weight: 100 parts of dimethylcyclosiloxane, 20-50 parts of phenylsiloxane, 5-10 parts of a silane coupling agent, 0.1-1 part of an alkaline catalyst, 5-100 parts of a nonionic surfactant and 10-90 parts of a solvent. A transparent hydrophobic film can be formed on the surface of glass, when water issprayed on the surface of the glass, water drops are formed, a contact angle reaches up to 110 degrees, the dropping speed of the water drops is greatly increased, and the water drops can automatically roll off without marks, so that the problem of unclear line of sight is solved.

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...
