摘要
研究硫化和补强体系对氯丁橡胶/天然橡胶(并用比为70/30)并用胶性能的影响。结果表明:硫黄对胶料的硬度影响最大,氧化锌/氧化镁/硫黄/促进剂DM用量比为6/3/5/0.3、硫化时间为60 min时,胶料的拉伸强度最高;炭黑N550用量为40份和白炭黑用量为20份时,胶料的加工性能、物理性能、耐水性能和绝缘性能较好。
The effect of curing and reinforcing systems on the properties of CR/NR blends（blending ratio was 70/30） was studied.The results showed that,sulfur has the greatest impact on the hardness of the vulcanizate.When the blending ratio of zinc oxide/magnesium oxide/sulfur/accelerator DM was 6/3/5/0.3 and curing time was 60 min,the tensile strength of the vulcanizate was the highest.When the amount of carbon black N550 was 40 phr and that of silica was 20 phr,the processability,physical properties,water resistance and insulation performance of the vulcanizate were preferable.
