摘要
研究恒粘剂OPRHAZ对天然橡胶(NR)性能的影响,并与塑解剂A86进行对比。结果表明,恒粘剂OPRHAZ通过与NR的化学反应来降低NR的门尼粘度,不减小NR相对分子质量,降低NR凝胶含量,提高NR胶料物理性能。恒粘剂OPRHAZ在稳定NR停放过程中的门尼粘度、提高NR胶料的物理性能方面比传统塑解剂A86具有优势。
The effects of viscosity stabilizer OPRHAZ on the properties of NR were studied and compared with peptizer A86. The experimental testing results showed that the Mooney viscosity of NR was reduced by OPRHAZ via chemical reaction between NR and OPRHAZ, which had no effect on the molecular weight of NR and reduced the gel content, and thus the physical properties of NR were improved. OPRHAZ was better than A86 in stabilizing the Mooney viscosity of NR during storage and improving the physical properties of NR vulcanizates.
