Abstract

The invention discloses high-temperature-resistant and flame-retardant organic glass which comprises, by weight parts, 80-100 parts of methyl methacrylate, 10-15 parts of styrene, 15-20 parts of alpha-fluoromethyl acrylate, 20-25 parts of rubber particles, 10-15 parts of composite flame retardant, 1-2 parts of initiator and 2-3 parts of crosslinking agent. The high temperature resistance of the high-temperature-resistant and flame-retardant organic glass is improved by introducing fluorine element and styrene and adding modified silicone rubber, the flame retardancy of the high-temperature-resistant and flame-retardant organic glass is improved by adding a suitable flame retardant system, the impact resistance of the high-temperature-resistant and flame-retardant organic glass is improvedthrough the combined action of the modified silicone rubber, a silane coupling agent, modified nano magnesium hydroxide and a crosslinking agent, and the problem of reduced mechanical properties of the organic glass is solved.

Description

technical field [0001] The invention relates to the technical field of organic glass, in particular to a high-temperature-resistant and flame-retardant organic glass. Background technique [0002] Polymethyl methacrylate (PMMA), commonly known as "plexiglass", is a typical transparent polymer material. Due to the advantages of good transparency, chemical stability and weather resistance, easy dyeing, easy processing, beautiful appearance, light weight, and processing adaptability, it has been developed rapidly in recent years and widely used in aviation, construction, agriculture, and optical instruments. and other fields. However, polymethyl methacrylate is extremely flammable and has poor heat resistance, which limits the application of polymethyl methacrylate. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a high temperature resistant flame retardant organic glass, which has high temperat...
