| 中文摘要: |
| 采用正交设计法研究硫黄/过氧化物并用硫化体系中不同助交联剂对天然橡胶(NR)性能的影响。结果表明：甲基丙烯酸锌(ZDMA)、N,N′-间苯基双马来酰亚胺(HVA-2)和三烯丙基异三聚氰酸酯(TAIC)用量对拉断伸长率有高度显著影响；ZDMA、HVA-2和TAIC用量对撕裂强度和伸张疲劳性能有显著影响；1, 4-丁二醇二丙烯酸酯(BDDA)对拉断伸长率、撕裂强度和伸张疲劳性能有一定影响；ZDMA对NR的热氧老化性能有显著影响,其他因子对热氧老化性能有一定影响；在正交实验的设计范围内,天然橡胶综合性能较好的配方为：ZDMA 2,HVA-2 1.5,TAIC 0.5,BDDA 0.5。 |

| The effect of different coagent on the property of the natural rubber based on the sulfur and peroxide curing system was investigated by Orthogonal Design Method. The results showed that zinc methylacrylate(ZDMA)、Triallyl isocyanurate (TAIC) and N, N′-m-Phenylene Bismaleimide(HVA-2) had highly significant effect on the tensile strength of NR composites. The addition level of ZDMA、HVA-2 and TAIC had significant effect on the tear strength and fatigue property. 1,4-butylenediacrylate (BDDA) had influence on the tensile strength tear strength and fatigue property. ZDMA had significant effect on the aging resistance, and the other factor had some extent influence of NR composites. The optimized curing system was as follows: ZDMA/2,HVA-2/1.5,TAIC/0.5,BDDA/0.5 |
