Abstract

The invention discloses anti-aging and high-toughness organic glass. The anti-aging and high-toughness organic glass is prepared from, by weight, 120-150 parts of methyl methacrylate, 10-15 parts of diacrylate sebacate, 9-12 parts of polystyrene resin, 6-10 parts of modified nano silicon dioxide, 8-12 parts of sodium silicate, 4-6 parts of polyaryl amide, 2-4 parts of lead methyl methacrylate, 1-3parts of epoxy resin, 1-2 parts of lauroyl peroxide, 1.5-3 parts of plasticizer, 0.5-0.9 part of n-butyl alcohol, 0.3-0.7 part of di-tert-butyl peroxide, and 0.3-0.6 part of dicumyl peroxide. The invention discloses the preparation method of the anti-aging and high-toughness organic glass. The organic glass is excellent in anti-aging performance and high in toughness, and benefits of an enterprise are improved.

Description

technical field [0001] The invention relates to organic glass, in particular to an anti-aging high-toughness organic glass and a preparation method thereof. Background technique [0002] Plexiglass is a popular name, abbreviated as PMMA. The chemical name of this polymer transparent material is polymethyl methacrylate, which is a polymer compound formed by the polymerization of methyl methacrylate. It is an important thermoplastic that was developed earlier. 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 good transparency, chemical stability, mechanical properties and weather resistance, easy to dye, easy to process, and beautiful appearance. Current plexiglass also has the defects of poor aging resistance and toughness, and these defects have seriously affected the use of plexiglass. Contents of the inven...
