增粘树脂对TPI/NR并用胶性能的影响

研究增粘树脂品种和用量对反式1，4-聚异戊二烯(TPI）/NR（并用比为15/85）并用胶性能的影响。结果表明，采用2～4份C₅石油树脂的TPI/NR并用胶在保持较好的物理性能和耐热空气老化性能的基础上，混炼胶粘合强度提高，硫化胶生热降低，是一种较为理想的全钢子午线轮胎胎肩垫胶配合。;The influence of the type and addition level of tackifying resins on the properties of TPI/NR blend with blending ratio of 15/85 was investigated.The results showed that，by using 2～4 phr CC₅ petroleum resin，the adhesion strength of TPI/NR blend improved，the heat build-up decreased，and the physical properties and thermal aging property were better，the TPI/NR blend with this formulation could be an ideal compound of TBR tire shoulder pad
