Embodiment 1
[0010] A preparation method for wear-resistant shoe soles, the method comprising the following steps: weighing the following raw materials according to the mass parts: 70-78 parts of EPDM rubber, 11-13 parts of carbon black, 5-7 parts of triethylaluminum, 10-12 parts of p-nitrophenol, 10-12 parts of polystyrene, 30-35 parts of natural 3L rubber, 5-8 parts of polyvinyl alcohol, 11 parts of talcum powder; When the temperature reaches 110-113°C, all raw materials have been mixed evenly, and the mixture is poured out; then the mixture after banburying is granulated by a granulator to obtain granules with a diameter of 2-3cm. cooling in a water tank, and then drying at room temperature; injection molding the dried pellets at a mold temperature of 190±3°C and a vulcanization time of 250±10 seconds to obtain shoe soles.
[0011] The main properties of the prepared sole are as follows: Tensile strength MPa: 24, % elongation at break: 580, % permanent deformation: 32, Shore hardness: ...
