中文摘要: |
研究炭黑对反式-1,4-聚异戊二烯(TPI)及其并用胶性能的影响。结果表明,填充炭黑后,TPI混炼胶的结晶度和物理性能下降;采用粒径较小的炭黑补强的TPI硫化胶、NR/TPI和SBR/TPI并用硫化胶的物理性能较好,但动态性能较差,采用粒径较大的炭黑补强的这3种胶料的动态性能较好,但物理性能较差;采用炭黑N330补强的NR/TPI和SBR/TPI并用胶综合性能较好,可用作高速低滚动阻力轮胎胎面胶。 |
英文摘要: |
The effect of carbon black on the properties of trans-1,4-polyisoprene (TPI) was investigated.The results showed that the crystallinity and physical properties of TPI mix decreased with addition of carbon black;the better physical properties,but the poorer dynamic properties of TPI,NR/TPI and SBR/TPI vulcanizates were obtained by using the carbon black with smaller particle size,in contrast,the better dynamic properties,but the poorer physical properties of above 3 vulcanizates were obtained by using the carbon black with larger particle size;and NR/TPI and SBR/TPI blends had better comprehensive properties,and could be used in the tread of high speed and low rolling resistance tire. |
