Problems solved by technology

[0003] There are many ways to manufacture plexiglass in the prior art, but the plexiglass prepared by the traditional method has low properties such as transparency, elasticity, and wear resistance. The glass transition temperature of general PMMA is about 105°C, and the heat distortion temperature is only 95°C, the actual use temperature is lower than 80°C, and its function will decline after a period of use, especially the plexiglass prepared by the prior art is relatively rough, not fine enough, and has poor heat resistance, which is prone to thermal deformation. Poor heat resistance will seriously affect the service life of plexiglass, so it is imperative to modify the heat resistance of plexiglass

Description

technical field [0001] The invention relates to the field of glassware manufacturing, in particular to a method for making a high-strength heat-resistant plexiglass fruit plate. Background technique [0002] Plexiglass (Polymethyl methacrylate) 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. [0003] There are many ways to manufacture plexiglass in the prior art, but the plexiglass prepared by the traditiona...
