Embodiment 1
[0033] A coffee grounds shoe material, comprising the following raw materials in parts by weight:
[0034]
[0035] The isocyanate is preferably diphenylmethane diisocyanate.
[0036] Each part of the modified SBS includes the following raw materials in parts by weight:
[0037]
[0038] The modified SBS is prepared by the following method:
[0039] S1. According to parts by weight, add tin tetrachloride and calcium carbonate into the reaction device, heat to 70°C, and stir at a speed of 300r / min for 10min, obtain mixture A after cooling, and set aside;
[0040] S2. According to weight parts, add SBS and carbon black to the mixture A obtained in step S1, heat to 40°C, continue to stir for 8min, then heat the mixed system to 160°C and send it to a granulator for extrusion and granulation to obtain the improved sex SBS.
[0041] Each part of the surfactant is a mixture of sodium dodecylbenzenesulfonate, fatty acid glyceride and sodium hydroxysulfonate in a weight ratio ...
