[0022] Add 10 parts of nano-alumina whiskers with an average particle size of 30nm into ethanol and mix evenly, then add 5 parts of silane coupling agent and 1 part of titanate coupling agent, carry out ultrasonic vibration for 0.5h, filter and dry, at 130°C After being activated for 7 hours at low temperature, it was cooled to room temperature to obtain 10 parts of modified nano-alumina whiskers. Dry 100 parts of polyvinyl chloride material in a vacuum oven at 75 °C for 12 hours, then cool to 30 °C, add 5 parts of CaCO 3 Fill and stir well. Add 1 part dibasic lead stearate and 1 part dibutyltin dilaurate heat stabilizer, 5 parts dioctyl phthalate (DOP) and 5 parts di-n-butyl sebacate (DBS) plasticizer , Stir evenly, the stirring temperature is 65°C, and keep warm for 3h. Mix the modified nano-alumina whiskers with PVC, stir evenly, and keep the stirring temperature between 60°C. The final material whose temperature was lowered to 40° C. was put into a twin-screw extruder f...

[0024] Add 20 parts of nano-alumina whiskers with an average particle size of 35nm into ethanol and mix evenly, then add 4 parts of silane coupling agent, 1 part of titanate coupling agent and 1 part of aluminate coupling agent, and perform ultrasonic vibration for 0.6h , filtered and dried, activated at 140°C for 9h and then cooled to room temperature to obtain modified nano-alumina whiskers. Dry 100 parts of PVC in a vacuum oven at 80°C for 11 hours, then cool to 35°C, add 6 parts of CaCO 3 Fill and stir well. Add 1 part of dibasic lead stearate and 2 parts of calcium stearate heat stabilizer, 5 parts of dibutyl phthalate (DBP) and 6 parts of di-n-butyl sebacate (DBS) plasticizer, Stir evenly, the stirring temperature is 85°C, and keep warm for 4h. Mix 20 parts of nano-alumina whiskers with PVC after modification, stir evenly, and keep the stirring temperature between 70°C. The final material whose temperature was lowered to 45° C. was put into a twin-screw extruder for e...
