Problems solved by technology

Plexiglass is commonly known as acrylic, Zhongxuan acrylic, and acrylic. Plexiglass has a smooth surface, bright colors, small specific gravity, high strength, corrosion resistance, moisture resistance, light resistance, good insulation performance, and good sound insulation; but plexiglass is easy to use. Combustion, low flame retardancy, low toughness, easy to crack
Flame retardants are usually added to improve the flame retardancy of plexiglass, but flame retardants will affect the toughness of plexiglass, making the flame retardancy and toughness of plexiglass unbalanced

Abstract

The invention discloses flame-retardant toughening organic glass. The flame-retardant toughening organic glass is prepared from, by weight, 130-150 parts of methyl methacrylate,15-20 parts of modified flame retardant, 3-5 parts of modified vermiculite, 1-2 parts of modified carbon nanotubes, 13-15 parts of diacrylate sebacate, 3-5 parts of trioctyl acetylcitrate, 10-12 parts of impact-resistant modifier, 4-6 parts of carboxymethyl cellulose and 1-1.4 parts of azodiisobutyronitrile. The glass is good in fire resistance, high in toughness and good in impact resistance.

Description

technical field [0001] The invention relates to the technical field of organic glass, in particular to a flame-retardant and toughened organic glass. Background technique [0002] Plexiglass is a polymer compound polymerized from methyl methacrylate, abbreviated as polymethyl methacrylate, abbreviated as PMMA. Plexiglass is widely used in daily life, industry, construction, aerospace and other aspects. There are four types of plexiglass: colorless and transparent, colored and transparent, pearlescent, and embossed plexiglass. Plexiglass is commonly known as acrylic, Zhongxuan acrylic, and acrylic. Plexiglass has a smooth surface, bright colors, small specific gravity, high strength, corrosion resistance, moisture resistance, light resistance, good insulation performance, and good sound insulation; but plexiglass is easy to use. Combustion, low flame retardancy, low toughness, easy to crack. Flame retardants are usually added to improve the flame retardancy of plexiglass, ...
