Example Embodiment
[0031] Example 1
[0032] A heat-resistant PVC shoe material, in parts by weight, comprising the following components:
[0033] 10 parts of PVC resin, 5 parts of light calcium carbonate,
[0034] 6 parts of nano titanium oxide, 1 part of MBS,
[0035] 2 parts of SMA, 3 parts of plasticizer,
[0036] 2 parts of stabilizer.
[0037] The preparation method includes the following steps:
[0038] (1) Add 10 parts of PVC resin, 5 parts of light calcium carbonate, and 6 parts of nano-titanium oxide into the mixer, and mix for 10 minutes at 100°C; add 1 part of MBS, 2 parts of SMA, and 3 parts of plasticizer , 2 parts stabilizer, continue mixing for 5 minutes;
[0039] (2) The mixed material is extruded and pelletized by a single-screw extruder. The process conditions are 120°C of the machine body temperature, 150°C of the die temperature, and a single-screw speed of 20r / min. The heat-resistant PVC shoe material is obtained by injection molding at 170°C.
