Effect of nano-zinc oxide on properties of NR compound

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.
