Abstract

The invention discloses a processing technology of polymethyl methacrylate. The technology comprises the following steps: (1) feeding methyl methacrylate, a comonomer, a crosslinking agent, rubber particles, an inorganic filler, mixed salt and additives into a reaction kettle; (2) heating and pressurizing the reaction kettle; stirring to react for 4-5h; and then moving out a semi-finished productfor later use; and (3) processing the semi-finished product by pouring, die releasing, stretching, cutting and polishing to obtain the finished polymethyl methacrylate. According to the technology, atraditional processing technology of the polymethyl methacrylate is optimized and improved, so that the properties such as temperature resistance, impact resistance, corrosion resistance and crackingresistance of the polymethyl methacrylate are effectively improved; the polymethyl methacrylate is high in comprehensive quality, and high in popularization and application value.
