AI Technical Summary

Technical Problem

Acrylic glass has poor heat resistance, which limits its application range. Although adding methacrylic acid to existing technologies can improve heat resistance, its water absorption and reactivity result in limited effectiveness.

Method used

Adding 5wt% to 15wt% of difunctional or trifunctional polyol acrylate as a crosslinking agent to methyl methacrylate, a basic component of plexiglass, combines methacrylic acid and isobornyl methacrylate to form a crosslinked structure that restricts the movement of polymer molecular chain segments and increases the glass transition temperature.

Benefits of technology

It effectively increases the glass transition temperature of plexiglass to above 145°C, maintaining the stability and transparency of the material, making it suitable for use in high-temperature environments.

Abstract

The present application relates to a kind of organic glass and its application.The component of the organic glass includes 30%~90% methyl methacrylate, 5%~15% polyol acrylate by mass percentage, wherein polyol acrylate is di-functional polyol acrylate or / and tri-functional polyol acrylate.By adding di-functional polyol acrylate or / and tri-functional polyol acrylate in organic glass, the glass transition temperature of organic glass can be effectively improved, and the glass transition temperature of organic glass can be as high as 145℃.In combination with methyl methacrylate and isobornyl methacrylate, which are known components that can improve the heat resistance of organic glass, the glass transition temperature of organic glass can be >140℃ under the condition of good transparency, polymerization and bending forming ability, so it is more suitable for practical use.
