[0029] A kind of preparation method of above-mentioned hydrolysis-resistant stable PC resin is characterized in that, comprises the following steps:
[0030] (1) Mix perfluorooctanoic acid potassium, high-sulfur pyrophyllite fine powder, and epoxy soybean oil in a high-speed mixer in proportion for 5-10 minutes;
[0031] (2) Weigh PC, polyether ether ketone, linear low density polyethylene, epoxy modified phenolic resin, calcium zinc stabilizer, antioxidant, lubricant according to the above formula, put into the mixer and stir for 1- 3 minutes to obtain mixed raw materials;
[0032] (3) Put the mixed raw material in step 2 and the mixing product in step 1 into a twin-screw extruder for reaction, and the material stays in the barrel for 1-2 minutes to obtain a reaction product. The twin-screw extruder The temperature of each zone is as follows: the temperature of the first zone is 240-250°C, the temperature of the second zone is 250-260°C, the temperature of the third zone is ...
