Problems solved by technology

[0003] At present, inorganic glass is mainly used for automotive glass. With the continuous improvement of vehicle lightweight and driving performance requirements, the performance requirements for automotive glass are also gradually increasing. Many aspects of inorganic glass cannot meet the current market demand. Polymer glass will Gradually replace traditional inorganic glass
[0004] Despite the above-mentioned excellent properties, the surface of polymer glass for automobiles is more prone to scratches and wear, aging and performance attenuation; and the processing and molding process of polymer glass for automobiles is complicated

Abstract

The invention provides an automobile high polymer glass and a preparation method of the automobile high polymer glass. The automobile high polymer glass comprises a high polymer glass matrix, an anti-aging layer arranged on at least one surface of the high polymer glass matrix, and a wear-resistant layer arranged on the anti-aging layer. The automobile high polymer glass has excellent anti-aging performance and wear-resistant performance. The preparation method of the automobile high polymer glass is simple and comprises the step of heating compression molding, thus meeting the requirement of a special curved surface of the automobile glass, and avoiding the problem that the high polymer glass is difficult to mold in the direct injection molding due to the poor fluidity.

Description

technical field [0001] The invention belongs to the technical field of automobile glass, and in particular relates to a polymer glass for automobiles and a preparation method thereof. Background technique [0002] Cars with different characteristics have various design requirements for the windows, such as opening holes in the windows, or designing sharp corners, smooth rounded corners or complex three-dimensional shapes on one side of the glass, etc., and these modeling requirements use traditional Inorganic laminated glass or tempered glass is not feasible, and these inorganic laminated glass and tempered glass are very expensive. But if polymer glass is used, the above-mentioned design scheme is easy to realize. Polymer glass has a high degree of transparency, and some polymer glasses have higher light transmittance than inorganic glass, which can meet the needs of light transmission first; at the same time, polymer glass is a long-chain polymer compound, and the molecul...
