Embodiment 1
[0025] A high-performance polyvinyl chloride alloy pipe made of the following raw materials by weight: 100 kg of PVC, 0.5 kg of organotin stabilizer, 10 kg of fluororubber, 2 kg of ABS, 2 kg of ACR, and 3 kg of nano-calcium carbonate , 0.4 kg of calcium stearate, 0.4 kg of paraffin wax, 0.1 kg of OPE wax, 0.01 kg of carbon black, and 0.4 kg of titanium dioxide.
[0026] Preparation Process:
[0027] a) Weigh each raw material according to the formula quantity, mix polyvinyl chloride resin, powdered fluororubber, stabilizer, nano-scale additives, processing aids, lubricants, and colorants at 100°C, and within 20 minutes;
[0028] b) put the above mixture into the cold mixer to cool to 25°C, and put it into the drying silo;
[0029] c) Extrude the mixture in the drying silo into pipes with conical twin-screws. The process parameters are selected as follows: body temperature: 150-200°C, confluence core temperature: 180-150°C, head temperature: 170-220°C; Host speed: 10-90 rpm,...
