Embodiment 1
[0045] The present embodiment provides a kind of preparation method of modified polyvinyl chloride plastic, it comprises the following steps:
[0046] (1) Weighing raw materials: Weigh 60g of polyvinyl chloride resin powder, 27g of plasticizer, 5.7g of hydrogenated nitrile rubber, 4.3g of stabilizer (paraffin-calcium stearate), flame retardant (polyethylene wax and polytetrafluoroethylene Vinyl fluoride) 1.3g, lubricant (Sb 2 o 3 , Mg(OH) 2 )1.7g;
[0047] (2) Ingredients mixing: Add polyvinyl chloride resin powder into the mixer, start the mixer to preheat, then add plasticizer and stabilizer, continue to heat up, mix, heat up to 85-90°C, and put in hydrogenated nitrile For rubber, stabilizer, flame retardant, lubricant, heat up to 100-135°C, set the speed of the mixer to 1300r / min, and carry out high-speed mixing to obtain the mixture;
[0048] (3) Extrusion molding: Put the mixed material described in step (2) into the hopper of the twin-screw extruder, inject it by the...
