摘要
研究纳米氧化锌等量或减量替代间接法氧化锌对NR胶料性能的影响。结果表明 ,当纳米氧化锌等量或减量 3 0 %替代间接法氧化锌应用时 ,胶料的焦烧时间和正硫化时间延长 ,抗硫化返原性能提高 ,硫化胶的邵尔A型硬度、3 0 0 %定伸应力和拉伸强度增大 ;当纳米氧化锌减量 60 %～ 80 %使用时 ,胶料的抗硫化返原性能下降 。
The effect of nano-zine oxide on the properties of NR compound was investigated.The results showed that the scorch time and optimum cure time of NR compound extended and its anti-reversion improved,and Shore A hardness,tensile strength and modulus at 300% of vulcanizate increased by using nano-zinc oxide instead of indirect zinc oxide by equal weight or 30% reduced weight;and the anti-reversion of compound deteriorated,and the tensile strength and tear strength increased by using 60%～80% reduced nano-zinc oxide.
