摘　　要：研究天然橡胶(NR)胶料的耐低温性能。结果表明,NR胶料的耐低温性能可以通过橡胶并用、改变填充剂和增塑剂种类、调整硫黄用量等方式进行提高。玻璃化温度低且与NR相容性好的增塑剂可以改善胶料的耐低温性能;选用低结构度炭黑可以明显改善胶料的耐低温性能;加入树脂对胶料的耐低温性能不利;促进剂并用对胶料的耐低温性能基本无影响,但硫黄用量对胶料的耐低温性能影响很大。The low temperature resistance of natural rubber(NR)compound was studied.The results showed that the low temperature resistance of NR compound could be improved by rubber blending,optimization of the filler and plasticizer type,and adjustment on the sulfur amount.The plasticizer with low glass transition temperature and good compatibility with NR could improve the low temperature resistance of the compound.The low temperature resistance of the compound could be obviously improved by using low structural carbon black.The addition of resin was unfavorable to the low temperature resistance of the compound.The combination of accelerators had little effect on the low temperature resistance of the compound,but the sulfur addition level had a great effect on the low temperature resistance of the compound.
