SDT/S在天然胶配方中的应用研究

庞俊 李铁贵 张兴华

  摘要:研究了SDT/S对天然胶胶料配方各项性能的影响。结果表明:在配方中使用SDT/S,对天然胶胶料起硫化促进作用,为保持原水平的硫化特性,可以适当减少促进剂的用量;可有效提高胶料过硫化条件下的300%定伸应力、扯断强度、邵氏硬度、撕裂性能、磨耗性能,可有效提高正硫化或过硫化条件下的胶料与帘线间的附着力。

ABSTRACT The effect of the SDT/S on the properties of NR compound was investigated The results showed that SDT/S plays the advanced role in NR compound,in order to keep the vulcanizate properties level as before may decrease some accerlator;the physical properties of overcured vulcanizate,the adhesion strength of optimum cure or overcured valcanizate between rubber and cord were improved by adding 2 phr of SDT/S to NR compound.
Keywords:SDT/S;optimum cure;overcure;properties resistant
