中文摘要: |
试验研究环保促进剂MTT(3-甲基-2-噻唑硫酮)替代促进剂ETU(亚乙基硫脲)的效果。结果表明,按标准检验配方进行对比,MTT-80和MTT的性能均优于ETU。按实用试验配方进行对比,对于W型氯丁橡胶(CR)SN232和M-40,与含ETU胶料相比,含MTT-80胶料的焦烧安全性好,硫化曲线平坦,耐热老化性能优异,耐臭氧性能相当,拉伸性能稍逊,但也有较好水平,以MTT-80替代ETU具有实用生产价值;而对于WRT型CR(S-40V),含MTT-80与ETU的胶料性能差距较大,还需进一步探讨。 |
英文摘要: |
In this study,environmentally-friendly accelerator MTT(3-methyl-2-thiazolyl-thione)was applied in CR compound and compared with accelerator ETU(ethylene thiourea).The results showed that,using standard formula,the performance of MTT-80 and MTT were better than ETU.With practical formula,it was found that in W-type CR(SN 232 and M-40)compound,compared with the ETU compound,the MTT-80 compound had better scorch safety,flat vulcanization curve,better heat aging properties,equivalent ozone resistance,slightly inferior tensile properties which,however,were still at a good level,and thus MTT80 could be used to replace ETU in practical production.For WRT-type CR(SV-40),there was a big difference between compound properties of MTT-80 and ETU compounds,and further study was needed. |
