Cold-resistant shoe outsole composition and preparation method thereof

The invention discloses a cold-resistant shoe outsole composition, which is prepared from the following ingredients in parts by weight: 70 to 100 parts of EVA particles, 20 to 40 parts of diisocyanate, 8 to 12 parts of POE copolymers, 7 to 15 parts of natural latex, 6 to 8 parts of cosolvents and 13 to 17 parts of polyhydric alcohols. The composition has the beneficial effects that the EVA particles can ensure that the shoe outsole has enough resilience, the diisocyanate and the polyhydric alcohols react to form a cross-linked polymer, the POE copolymer is inserted into the cross-linked polymer in a penetrating manner, and then the EVA particles are wrapped, so that the composition has enough strength and cold resistance. 本发明公开了一种耐寒鞋大底组合物，按重量份数计，包括如下组分：EVA颗粒70-100份、二异氰酸酯20-40份、POE共聚物8-12份、天然乳胶7-15份、助溶剂6-8份和多元醇13-17份。本发明的有益效果是：本发明EVA颗粒可保证鞋大底具有足够的回弹性，二异氰酸酯和多元醇反应后形成交联聚合物，POE共聚物穿插在交联聚合物中，再将EVA颗粒包裹，使得组合物具有足够的强度和耐寒性。
