Example Embodiment
[0050] Example 1:
[0051] (1), stir 12.2 parts of PP resin, 5 parts of grafted PP / POE, 0.2 part of titanate coupling agent, and stir for 1 minute in a high-speed mixer at a low speed;
[0052] (2), with 50 parts of heavy calcium carbonate, 30 parts of precipitated barium sulfate, 1 part of talcum powder, 1 part of compound lubricant, 0.2 part of sodium benzoate, 0.2 part of antioxidant, in the material after mixing with step (1) Stir on high speed for 15 minutes;
[0053] (3) adding 0.2 part of DCP to the mixed material of step (2) and stirring at low speed for 2 minutes;
[0054] (4) The material after the stirring in step (3) is put into the twin-screw melt extruder of (L / D, 40:1) for melt extrusion and granulation. 220℃, 3rd zone 200-220℃, 4th zone 200-210℃, 5th zone 190-230℃, 6th zone 190-230℃, 7th zone 180-230℃, 8th zone 180-230℃, 9th zone 180-230 ℃; eight zones open the vacuum port for vacuuming. The screw speed is 350-500 rpm.
