| 摘 要： | 将低相对分子质量反式-1，4-聚异戊二烯蜡（LMTPIW）代替芳烃油用于天然橡胶（NR）和反式-1，4-聚异戊二烯（TPI）并用胶中．研究其对并用胶性能的影响。结果表明，用LMTPIW代替芳烃油用于NR／TPI并用胶中，操作方便，可改善混炼胶的加工性能，混炼胶的焦烧时间延长；提高了硫化胶的拉断伸长率、撕裂强度、屈挠性能；改善了炭黑的分散性；热空气老化性能略有下降。LMTPIW用量在10～15份时，与加入5份芳烃油后的增塑效果相当．屈挠性能可提高2～4倍，胶料的综合性能最佳。

| Abstract: | The effects of low molecular weight trans-1,4-polyisoprene wax(LMTPIW) on the properties of NR/TPI compounds and vulcanizates were studied,and compared with that of aromatic oil.The results showed that the processibility of NR/TPI blends was improved by using LMTPIW instead of aromatic oil.The scorching time was extended.The elongation at break ,and tear strength of NR/TPI vulcanzates were improved.At the same time the dispersion of carbon black in the NR/TPI compounds containing LMTPIW was also improved. Compared with aromatic oil,LMTPIW could impart good flex fatigue for NR/TPI vulcanizates,but depressed hot air aging properites of NR/TPI vulcanizates lightly at the same time.When the amount of LMTPIW was 10~15phr,the flex crack was improved 2~4 folds. |
