摘要:
制备了4种3，4-结构摩尔分数不同的液体聚异戊二烯（LIR），考察了芳烃油及不同3，4-结构摩尔分数的LIR作为增塑剂对于天然橡胶（NR）的交联密度、物理机械性能、动态力学性能及微观结构的影响。结果表明，随着LIR中3，4-结构摩尔分数的增加，NR的交联密度增加。LIR不仅起到增塑的作用，还可与NR形成共交联网络。与芳烃油相比，以LIR作为增塑剂的NR硫化胶的定伸应力及拉伸强度更优。同时填充3，4-结构摩尔分数较高的LIR的NR硫化胶具有良好的抗湿滑性能以及较低的滚动阻力。LIR可以提高炭黑在NR基体中的分散性。
Abstract:
Four kinds of liquid polyisoprene (LIR) with different mole fraction of 3,4- unit were prepared, and the effects of aromatic oil and LIR with different mole fraction of 3,4- unit as plastici-zers on the cross-linking density, physical and mechanical properties, dynamic mechanical properties and microstructure of natural rubber (NR) were investigated. The results showed that the cross-linking density of NR increased with the increasing mole fraction of 3, 4-unit in LIR. LIR played the role of plasticization and formed a co-crosslinking network with NR. Compared with aromatic oil, NR vulcanizate with LIR as plasticizer had better tensile stress and tear strength. At the same time, LIR with high mole fraction of 3,4- unit had good wet sliding resistance and low rolling resistance. LIR could improve the dispersion of carbon black in NR matrix.
