中文摘要: |
研究抗疲劳剂PAPI的性质及其在缺气保用轮胎支撑胶中的应用。抗疲劳剂PAPI含有多官能团马来酰亚胺化合物,其多苯环结构有助于炭黑的分散,并可通过Alder-Ene反应直接参与橡胶的硫化交联,重构交联网络。试验结果表明:将抗疲劳剂PAPI应用于支撑胶,混炼胶的门尼粘度降低,焦烧时间延长;硫化胶的拉伸强度和拉断伸长率提高,压缩疲劳温升降低,耐屈挠性能大幅提高;可提高缺气保用轮胎的安全性。 |
英文摘要: |
The quality of anti-fatigue additive PAPI and its application in support compound of run-flat tire were investigated.Anti-fatigue additive PAPI contained polyfunctional maleimide compound,and its structure of multiple benzene rings contributed to dispersion of carbon black.Through the Alder-Ene reaction,anti-fatigue additive PAPI could directly participate in the vulcanization cross-linking of rubber, reconstruct the cross-linked network.The results showed that,by using anti-fatigue additive PAPI in the support compound,the Mooney viscosity of the compound was reduced,and the scorch time was prolonged;the tensile strength and elongation at break of the vulcanizate were improved,the compression fatigue temperature rise was reduced,the flexing resistance was improved greatly,and the safety of run-flat tire was improved. |
