Abstract

The invention relates to the technical field of organic materials and discloses an organic glass sheet material with excellent mechanical properties. When a prepared toughened composite material, serving as a modifying agent, is synthesized into a multipolymer with methyl methacrylate in a polymerization reaction, crosslinking modification is carried out to increase crosslinking points of a molecular chain and prevent cracks from being expanded, so that the mechanical properties are enhanced; compared with an existing methyl methacrylate polymer, the multipolymer has the advantages that the impact strength, tensile strength, Brinell hardness and static bending strength are much higher than those of the existing methyl methacrylate polymer; organic glass prepared by the invention has excellent mechanical properties, the light transmission performance is also improved and an applicable range is wider; the utilization function and service life of the organic glass are greatly improved, aspecific working environment is met and the damage rate is reduced; the practical significance of expanding an organic glass selling market can be realized and the organic glass sheet material is a technical scheme which is extremely worthy of being popularized and applied.

Description

technical field [0001] The invention belongs to the technical field of organic materials, and in particular relates to an organic glass plate with excellent mechanical properties. 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. Plexiglass is divided into four types: 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. Plexiglass is also called gelatin glass, acrylic and so on. [0003] The working environment of plexiglass is mostly exposed to the atmospher...
