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 anti-flaming organic glass which comprises the following raw materials in parts by weight: 100-120 parts of methyl methacrylate, 5-10 parts of composite flame retardant, 10-12 parts of oxalic acid acrylate, 1-3 parts of trioctyl acetylcitrate, 13-17 parts of rubber particles, 2-4 parts of carboxymethylcellulose, 2-4 parts of modified carbon fibers and 0.5-1 part of lauroyl peroxide. The preparation process of the composite flame retardant comprises the following steps: uniformly mixing diethyl chlorophosphate with tetrahydrofuran; regulating the temperature; adding triethylamine and uniformly mixing; dropwise adding hydroxyethyl acrylate into the tetrahydrofuran solution and stirring under the heat preservation mode; increasing the temperature to the room temperature; stirring under the heat preservation mode and then purifying, thereby acquiring a material A; mixing the material A with expansible graphite and ammonium polyphosphate, thereby acquiring the composite flame retardant. The invention also discloses a preparation method for the anti-flaming organic glass. The anti-flaming organic glass is high in fire resistance and toughness.

Description

technical field [0001] The invention relates to the technical field of organic glass, in particular to a flame-retardant 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 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 retarda...
