Embodiment Construction
[0018] A wear-resistant and toughened PVC pipe modified by adding a rare earth coupling agent to activate vermiculite, characterized in that the PVC pipe includes PVC resin, filler, stabilizer and plasticizer; the filler is a rare earth coupling agent Activated vermiculite, the stabilizer is a calcium-zinc composite heat stabilizer, and the plasticizer is chlorinated polyethylene.
[0019] Relative to 100 parts by weight of the PVC resin, the filler is 8-10 parts, the stabilizer is 4-6 parts, and the plasticizer is 15-20 parts.
[0020] The preparation method of described rare earth coupling agent activated vermiculite is:
[0021] (1) Dry the vermiculite in an oven at 110°C for 2-3 hours, cool to room temperature and grind it through a 200-300 mesh sieve to obtain vermiculite powder;
[0022] (2) Put the vermiculite powder in a high-speed kneader, control the speed at 600r / min and stir for 20-30min, wait until the temperature rises to 100-110°C, keep the temperature constant...
