摘要
采用新型多功能硫化助剂WL207(简称WL207)替代传统硫化体系中的硫化剂和促进剂,研究其对天然橡胶(NR)/溶聚丁苯橡胶(SSBR)并用子午线轮胎胎面胶性能的影响。多官能团的结构特征使WL207兼具交联、促进和活化作用。结果表明:与普通硫黄硫化体系胶料相比,采用WL207的胶料的硫化速度和硫化程度相当,抗硫化返原性能较好;WL207与胶料的相容性好,易分散,不喷霜;硫化胶硬度低、耐磨性能好,可平衡抗湿滑性能与物理性能;使用WL207可实现NR/SSBR较好地相容及共硫化。
A new multi-functional vulcanizing agent WL207 was used to replace the vulcanizing agent and accelerator in the traditional vulcanization system,and its effect on the properties of the tread compound of radial tire[natural rubber(NR)/solution polymerized styrene butadiene rubber(SSBR)blend]was studied.The structural characteristics of the multi-functional groups endow WL207 with the functions of crosslinking,promoting and activating.The test results showed that,compared with the compounds with common sulfur vulcanization system,the vulcanizing rate and vulcanizing degree of the compound with WL207 were equivalent,and the reversion resistance was better.WL207 had good compatibility with rubber compounds,could be easily dispersed in rubber compounds,and no blooming occurred.The compounds vulcanized by WL207 had low hardness,good wear resistance,and good balance between the wet skid resistance and physical properties.In addition,the application of WL207 could also improve the compatibility of NR/SSBR and achieve good co-vulcanization effect.
