Abstract

The invention discloses a preparation process of high-performance engineering plastic resistant to strong acid and alkali. The plastic is prepared from, by mass, 60-70 parts of unsaturated polyester resin, 8-10 parts of nano zirconia, 8-10 parts of glass fibers, 12-15 parts of titanium dioxide, 15-18 parts of pulverized fuel ash, 5-6 parts of zinc phosphate, 5-6 parts of mica powder, 2 parts of leveling agent, 1 part of methyl ethyl ketone peroxide, 1.2 parts of LCC compound accelerator and 0.3 part of benzoin. According to the preparation process of the high-performance engineering plastic resistant to strong acid and alkali, the rosin-modified unsaturated polyester resin is used as a main material and has good corrosion resistance, the processing performance of the finished product is good, and the plastic can be widely applied to chemical reagent storage containers. The high-performance engineering plastic resistant to strong acid and alkali prepared by the rosin-modified unsaturated polyester resin is low in curing temperature, and the energy consumption can be greatly reduced during production.
