Embodiment 1
[0029] A kind of novel PVC / CPVC sole composite material, by weight, comprises the following components:
[0030] 30 parts of PVC, 10 parts of CPVC, nano-CaCO 3 5 copies,
[0031] nano-SiO 2 2 parts, anti-aging agent 1 part, HALS 1 part,
[0032] HT-510 2 parts.
[0033] Its preparation method comprises the following steps:
[0034] (1) Add 30 parts of PVC, 10 parts of CPVC, 1 part of anti-aging agent, 1 part of HALS, and 2 parts of HT-510 into a high-speed mixer, and stir for 20 minutes to obtain a mixture;
[0035] (2) Transfer the mixture obtained in step (1) to the rubber mixing machine at 22 o'clock, continue to add 5 parts of nano-calcium carbonate, 2 parts of nano-silicon oxide, banbury 3 times at 140 ° C, and the roll distance is 0.5 mm, After the banburying is completed, enlarge the roller distance to produce the sheet, and cut it into a 30×50mm sheet to obtain a new type of PVC / CPVC shoe sole composite material.
Embodiment 2
[0037] A novel PVC / CPVC shoe sole composite material, in parts by weight, comprises the following components:
[0038] 60 parts of PVC, 15 parts of CPVC, nano CaCO 3 10 copies,
[0039] nano-SiO 2 8 parts, anti-aging agent 2 parts, HALS 3 parts,
[0040] 5 servings of HT-510.
[0041] Its preparation method comprises the following steps:
[0042] (1) Add 60 parts of PVC, 15 parts of CPVC, 2 parts of anti-aging agent, 3 parts of HALS, and 5 parts of HT-510 into a high-speed mixer, and stir for 30 minutes to obtain a mixture;
[0043] (2) Transfer the mixture obtained in step (1) to the rubber mixing machine at 22 o'clock, continue to add 10 parts of nano-calcium carbonate, 8 parts of nano-silicon oxide, banbury 5 times at 150 ° C, and the roll distance is 0.5 mm, After the banburying is completed, enlarge the roller distance to produce the sheet, and cut it into a 30×50mm sheet to obtain a new type of PVC / CPVC shoe sole composite material.
Embodiment 3
[0045] A novel PVC / CPVC shoe sole composite material, in parts by weight, comprises the following components:
[0046] 35 parts of PVC, 11 parts of CPVC, nano CaCO 3 6 servings,
[0047] nano-SiO 2 3 parts, anti-aging agent 1 part, HALS 2 parts,
[0048] 3 servings of HT-510.
[0049] Its preparation method comprises the following steps:
[0050] (1) Add 35 parts of PVC, 11 parts of CPVC, 1 part of anti-aging agent, 2 parts of HALS, and 3 parts of HT-510 into a high-speed mixer, and stir for 22 minutes to obtain a mixture;
[0051](2) Transfer the mixture obtained in step (1) to the rubber mixing machine at 22 o'clock, continue to add 6 parts of nano-calcium carbonate, 3 parts of nano-silicon oxide, banbury 4 times at 144 ° C, and the roll distance is 0.5 mm, After the banburying is completed, enlarge the roller distance to produce the sheet, and cut it into a 30×50mm sheet to obtain a new type of PVC / CPVC shoe sole composite material.
