Abstract

The invention discloses heat-resistant crack-resistant organic glass and a preparation method thereof; the heat-resistant crack-resistant organic glass comprises, by weight, methyl methacrylate, polycyclic norbornene methacrylate, butanediol diacrylate, epoxidized soybean oil acrylate, an impact modifier, 1-dodecanethiol, polyacrylamide, rubber particles, poly(butyl acrylate), nylon terpolymer, rare earth, azobisisobutyronitrile, dicumyl peroxide, diisobutyl phthalate, and ethyl 4-hydroxybenzoate. The heat-resistant crack-resistant organic glass and the preparation method thereof are provided herein; the organic glass has high glass transition temperature, good heat resistance and good mechanical properties, rarely cracks and has good economic benefit.

Description

technical field [0001] The invention relates to the technical field of glass, in particular to a heat-resistant and crack-resistant organic glass and a preparation method thereof. Background technique [0002] Polymethyl methacrylate, commonly known as plexiglass, has excellent optical properties, weather resistance and chemical corrosion resistance, good electrical insulation and biocompatibility, easy to process and shape, high mechanical strength silicate inorganic glass, widely used in aviation , navigation, architecture and everyday life. The current plexiglass still has brittle texture, poor mechanical properties, poor heat resistance, and is prone to cracking during production and use, and these all seriously affect the use of plexiglass. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a heat-resistant and crack-resistant organic glass and its preparation method. The organic gl...
