全SR农业轮胎胎面胶的研制

Development of all SR agricultural tire tread compound

从既降低成本又能满足农业轮胎胎面胶的各项性能要求出发 ,同时根据SR的性能及工艺特点 ,设计配方并进行优化 ,确定了S SBR/BR并用 (并用比 6 0 / 40 ) ,增大硫黄和软化增粘剂的用量 ,N2 2 0和N330并用 ( 6 3份 )作为补强填充剂 ,对苯二胺类防老剂作为主要防老剂的胶料配方 ,同时适当调整了加工工艺。试验结果表明 ,该配方不仅满足了农业轮胎胎面胶的性能要求 ,而且与现生产农业轮胎胎面胶相比 ,胶料成本降低36 3元·t-1。
