Abstract

The invention discloses an automobile glass surface waterproof agent, which comprises silane, an acid catalyst and an organic solvent. The silane includes long chain silane and short chain silane in the weight ratio of 1:3-3:1; and the weight ratio of silane, organic solvent and acid catalyst is 1-40:100:0.5-10. The invention also discloses a preparation technology and a coating technology of the automobile glass surface waterproof agent. The waterproof agent uses the mixture of long chain silane and short chain silane; uneven level between the long and short chain molecules results in increase in the hydrophobicity. The waterproof agent of the invention forms hydrophobic effect in the automotive glass surface, can improve the transparency of automotive glass under rainy conditions, improve traffic safety. The waterproof agent of the invention has the advantages of simple coating process, long-lasting hydrophobic effect time, and no use of a fluoride repellent material.

Description

technical field [0001] The invention relates to a rainproof agent for the surface of automobile glass, a preparation process and a coating process thereof. Background technique [0002] When the car glass is driving in the rain, raindrops often adhere to its surface, which makes it difficult for drivers to observe and affects their safe driving. At present, the purpose of rain protection is mainly achieved through the following methods: 1) Install a rain shield on the upper end of the glass window, which has a certain effect, but it is inconvenient to use with an additional device; 2) Surface liquid coating or treatment technology, mainly Use hydrophobic or hydrophilic coating solution. This method is simple to use, but the disadvantage is that the service life is short, the surface hydrophobic effect is not ideal, and its hydrophobic performance needs to be increased; and the hydrophilic film is easy to degrade; 3) Directly install hydrophobic glass. Although there are cu...
