Problems solved by technology

[0005] The purpose of the present invention is to overcome the problems in the prior art when polycarbonate is directly used as the window glass, which has poor wear resistance, weather resistance and water repellency, is easy to scratch, has poor sealing performance, and cannot be waterproof and anti-fog, which will affect the line of sight. Therefore, it is necessary to apply a coating on the surface of polycarbonate glass, but it is difficult for the coating in the prior art to significantly improve the wear resistance, weather resistance and water repellency of polycarbonate glass at the same time, and the coating is in polycarbonate glass. The adhesion on the carbonate glass is poor, which affects the use performance. A light-weight wear-resistant automobile side window glass and its preparation method are provided. The surface coating is coated on the polycarbonate base layer and the PC / ABS black edge layer. , the coating has strong adhesion to the resin layer, and can significantly improve the wear resistance, weather resistance and water repellency of the window glass, realize the lightweight of the car and improve the performance of the window glass at the same time

Abstract

The invention relates to the technical field of automobile window glass, and discloses a light-weight and wear-resistant automobile side window glass and a preparation method thereof. Edge layer, polycarbonate base layer and PC / ABS black edge layer are coated with surface coating, the coating composition of surface coating includes solvent, surface grafted polydimethylsiloxane nano-SiO 2 and polycarbonate-polydimethylsiloxane copolymer. The preparation method is as follows: using a two-color injection mold to inject the polycarbonate base layer first, and then injecting the PC / ABS black edge layer in the same mold; baking the polycarbonate base layer and the PC / ABS black edge layer to remove internal stress, And scrub the surface with alcohol solvent; shower and dry to get the surface coating. The invention coats the modified coating on the surface of the polycarbonate base layer and the PC / ABS black border layer, which greatly improves the wear resistance, weather resistance and water repellency of the side window glass.

Description

technical field [0001] The invention relates to the technical field of automobile window glass, in particular to a light-weight wear-resistant automobile side window glass and a preparation method thereof. Background technique [0002] With the continuous progress of society, people's living standards are also constantly improving, the demand for cars has also increased a lot than before, and the number of cars is also increasing. As countries implement policies that force automakers to reduce vehicle fuel consumption, vehicle lightweight has become an important breakthrough for major auto companies. According to statistics, every 1% reduction in vehicle weight can reduce fuel consumption by 0.6%-1.0%, and energy consumption is closely related to exhaust emissions. Therefore, the lightweight of automobiles is of great significance to energy saving and environmental protection. "Lightweight" has become an important national strategy, and more and more research institutions ...
