中文摘要:
      研究了活化剂Struktol A-73在天然橡胶及天然橡胶与丁苯橡胶并用胶中的应用特性,结果表明:胶料中加入Struktol A-73可改善胶料的抗硫化返原性和热稳定性;提高胶料的硫化效率;改进胶料的动态性能;降低胶料的生热和压缩永久变形;与噻唑类硫化促进体系并用,无亚硝胺污染环境的危险;对钢丝粘合性能造成的影响,在胶料老化之后即可降至最小;混炼工艺性能良好。它是一种特别有效的硫化活化剂,一般用量2~5份,适用于轮胎、减振块等厚壁模压制品,以改进制品的最终使用性能。
英文摘要:
      A study on application of Struktol A-73 in NR and NR/SBR blend is made.The results show that the addition of struktol A-73 to the compound has the following advantages:improved overcure-reversion resistance and thermal stability,increasead efficiency of vulcanization,improved dynamic performance,lower heat build-up and compression set,freefrom the potential pollution of nitrosamine,minimal adverse effect on the adhesion with steel cord after aging.Struktol A-73 offers development chemists a new possibility to improve the performance of tyre and thick sectioned industrial mouldings.
