摘要
研究抗硫化返原剂KA9188对绿色载重轮胎硫化胶抗硫化返原性、生热性能、耐磨性能和撕裂强度的影响。结果表明:KA9188用量不小于1.2份时,可以体现出抗硫化返原效果;KA9188可以有效地提高硫化胶的撕裂强度;在半有效硫化体系中,KA9188替代部分硫黄且硫化胶定伸应力适当降低时,硫化胶的耐磨性能大幅提高;在有效硫化体系中,采用少量KA9188替代部分硫黄可以降低硫化胶的压缩生热,提高耐磨性能。
The influence of anti-reversion agent KA9188 on the anti-reversion property,heat build-up,wear resistance and tear strength of green truck tire were studied. The results showed that,when the addition level of KA9188 was 1. 2 phr or more,it provided good anti-reversion effect. KA9188 could effectively improve the tear strength of the vulcanizate. In semi effective vulcanization system,when KA9188 was applied to replace part of sulfur and the tensile modulus of the vulcanizate was reduced accordingly,the wear resistance of the vulcanizate was improved significantly. In effective vulcanization system,by using a small amount of KA9188 to replace part of sulfur,the compression heat build-up of the vulcanizate was decreased and the wear resistance was improved.
