Glue for TPR material sole and preparation method thereof

The invention discloses a glue for a TPR material sole. The glue is prepared from the following raw materials in parts by weight: 90-110 parts of ethylene-vinyl acetate interpolymer, 25-35 parts of butyl rubber, 20-30 parts of coumarone-indene resin, 5-8 parts of synthetic paraffin resin, 15-25 parts of talcum powder, 4-6 parts of calcium carbonate and 0.5-1.5 parts of 2,6-di-tert-butyl-p-cresol.The glue product provided by the invention has a high softening temperature and a low brittle temperature, can be used at most temperatures without losing viscosity, and has good adhesive bonding performance for various materials; and nitrile-butadiene rubber is added to improve the flexibility and elasticity of the glue solution, improve the adhesive bonding strength and shorten the curing time. 本发明公开了种TPR材料鞋底用胶水，由以下重量份的原料制成：乙烯-醋酸乙烯共聚体90-110份，丁基橡胶25-35份，香豆酮-茚树脂20-30份，合成石蜡树脂5-8份，滑石粉15-25份，碳酸钙4-6份，2,6-二叔丁基对甲酚0.5-1.5份。本发明提供的胶水产品软化温度高，脆化温度低，能够适应大多数温度使用而不失去粘黏性，且对各种材料均由较好的胶接性能，加入丁晴橡胶改善胶液的柔韧性和弹性，提高胶接强度，缩短固化时间。
