Problems solved by technology

However, at present, most of the protective glass products in my country are composed of 4 layers and above functional materials, and their thickness is generally above 5mm. The process of product installation and maintenance is complicated and the cost is high, which greatly limits the use of protective glass in automobiles. Therefore, it has become an inevitable trend in the development of the protective glass industry to develop practical, light and thin protective slope glass with anti-smashing, high light transmittance, easy installation and maintenance.

Abstract

The invention relates to the technical field of research and development and manufacturing of functional glasses, and discloses a composite protection glass with excellent impact resistance. Accordingto the present invention, the selected back plate material has significant characteristics of good mechanical property, light weight and high optical transparency, the transmittance is up to 93-94%,the relative density is low, is 1.12-1.15, and is only 1 / 2 of the relative density of the inorganic glass, the mechanical strength and the toughness are more than 10 times higher than the mechanical strength and the toughness of the inorganic glass, the outstanding weather resistance and the outstanding aging resistance are provided, the impact resistance, the optical performance, the use performance and the like are comprehensively improved, the impact resistance is 15-20 times the impact resistance of the organic glass, and the prepared composite protection glass has significant advantages in the light weight and the safety of the key part of vehicles, building and other industries, and can meet the high-performance requirements of people on the safety protection glass.

Description

technical field [0001] The invention belongs to the technical field of R&D and manufacture of functional glass, and in particular relates to a composite protective glass with excellent impact resistance. Background technique [0002] Protective slope glass refers to a transparent material that has excellent optical properties like ordinary glass, but also has very high impact resistance and safety performance, also known as safety glass. Because of its ability to protect against various attacks, protective glass has played an important role in the protection of national dignitaries, military and police protection, and the safety of aerospace and financial activities. In recent years, with the development of the national economy and the continuous improvement of people's own security awareness, civilian protective glass has gradually penetrated into all aspects of social life, and its demand is growing rapidly, especially in the fields of automobiles and construction. In som...
