(1) in the high-speed mixer of 200L, press table 1 formulation ratio, with 65 parts of 5 parts of 15 parts of nano-calcium carbonates (particle diameter is 30~65 nanometers), talcum powder (east, Liaoning occasion 1250 orders) and water-ground limestones (particle diameter is 6~10 microns), stir with 400r/min speed, be docile and obedient preface then and add 10 parts of 3 parts of silane coupling agents, 6 parts of macromole compatilizer PP-g-MA and homo-polypropylene (melt flow rate (MFR) is 10g/10min), after finishing, stir with 1000r/min speed again and obtained mixture in 1 minute.Said mixture is joined in the feeding hopper of twin screw extruder, with length-to-diameter ratio be 40: 1, screw diameter be extrude in the twin screw extruder of 75mm, pelletizing, the engine speed of twin screw extruder is 250 rev/mins, 30 rev/mins of rate of feeding, the temperature of each section of forcing machine is followed successively by 150 ℃, 195 ℃, 195 ℃, 195 ℃, 195 ℃, 190 ℃, 190 ℃, 185 ℃, 180 ℃, 180 ℃, and final drying promptly obtains the pre-dispersed masterbatch HCT-4 of mineral filler.
(2) with 60 parts of atactic copolymerized polypropenes (MFR=0.6g/10min), 15 parts of environmental protection fire retarding agents (50 parts of TDE, 30 parts of PBDE and 20 parts of Sb
2O
3), the 10 parts of above-mentioned weight part meter of anti-impact modifier POE-g-MA proportion ingredients, in high speed mixer, mixed 2 minutes with 1000r/min speed.
(3) with the pre-dispersed masterbatch HCT-4 of 25 parts of mineral fillers and step (2) the gained mixing of materials of step (1), add 1 part of 3 parts of composite antibiosis masterbatch EMB-1 (20 parts of poly-(4-vinylpridine quaternary ammonium salt-acrylamide) antiseptic-germicide+20 part nano silicon load silver ion antiseptic-germicide+60 parts of acrylic resins) of above-mentioned weight part meter proportioning and 0.3 part of antioxidant 1010, Poly Propylene Wax again, in high speed mixer, mixed 1 minute with 500r/min speed.
(4) be that 40: 1, screw diameter are that the twin screw extruder of 75mm melt extrudes granulation, drying and vacuum-packed with the material that mixes through length-to-diameter ratio, obtain multifunctional modified random Co-polypropylene tubing PP Pipe Compound PPM-8.The performance index of PPM-8 are as shown in table 3.
The technical feature contrast of the multifunctional modified random Co-polypropylene tubing PP Pipe Compound of the various embodiments described above and Korea S star R200P dawn special material for tube sees Table 2, table 3.
