环氧化天然橡胶对白炭黑/天然橡胶硫化胶物理性能和减震性能的影响

研究不同环氧度环氧化天然橡胶（ENR）对白炭黑/天然橡胶（NR）硫化胶物理性能、减震性能及压缩疲劳生热性能的影响。结果表明：ENR可以提高白炭黑/NR硫化胶的物理性能和实用温度范围内的阻尼性能，降低硫化胶的压缩疲劳生热，其中环氧度为40％的ENR效果最优。;The effect of ENR with different epoxidization degrees on the physical property， damping property and compression fatigue properties of silica/NR vulcanizates was investigated.The results showed that，ENR could improve the physical property and damping property in application temperature range，and decrease the compression fatigue temperature rise of silica/NR vulcanizates.It was found that when the epoxidization degree of ENR was 40%，the effect was the best
