摘要
研究了活化剂ＳｔｒｕｋｔｏｌＡ－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ＳｔｒｕｋｔｏｌＡ－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。
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 vulcanizaimproved dynamic performance, lower heat build-up and compression set, freefrom thepotential 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.
