Abstract

The invention discloses anti-cracking organic glass, prepared from, by weight, 100-150 parts of methyl methacrylate, 11-14 parts of diethylene glycol dimethacrylate, 3-5 parts of tributyl citrate, 13-17 parts of rubber particles, 3-5 parts of modified montmorillonite, 0.3-0.5 part of azodiisobutyronitrile, 3-5 parts of an anti-impact modifier, and 2-4 parts of dodecyl mercaptan. The invention also discloses a preparation method of the organic anti-cracking glass. The anti-cracking organic glass has high toughness and good cracking resistance.

Description

technical field [0001] The invention relates to the technical field of organic glass, in particular to a crack-resistant organic glass and a preparation method thereof. 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 smooth surface, bright colors, small specific gravity, high strength, corrosion resistance, moisture resistance, light resistance, good insulation performance, and good sound insulation; The texture is crisper. In order to meet people's demand for plexiglass, it is necessary to provide a new plexiglass. Contents of the invention [0003] Base...
