摘　　要：采用高速离心的方法,改变天然橡胶(NR)中非胶物质的含量,分析非胶物质对硫化胶的力学性能和热老化性能的影响。结果表明:在本实验范围内,随着NR中非胶物质含量的增加,其力学性能和热老化性能增加。In the experiment we will discuss below,we altered the quantity of non-rubber substances after their being extracted from NR latex by ultracentrifugation,then we analyzed the effects of non-rubber substances on the mechanical and anti-aging performance of vulcanized NR.The result showed that,in a certain range,the mechanical and anti-aging performance improved with increasing amount of non-rubber substances.

关 键 词：非胶物质 力学性能 硫化
