将天然橡胶与反式-1,4-聚异戊二烯并用,通过调控配方中炭黑N 330的用量制备出具有硬度梯度的一系列橡胶试样,研究了共混硫化胶的物理机械性能和动态力学性能。结果表明,炭黑填充量为20份(质量)试样的综合物理机械性能较为优异;通过动态力学分析推测共混胶中反式-1,4-聚异戊二烯的熔融温度为47 ℃左右;电液伺服材料试验机的测试表明试样的固有频率随炭黑用量的增加及振幅和静态压缩载荷的减小而增大,动静刚度比均随炭黑用量和静态压缩载荷的增加而增大。

A series of rubber samples with hardness gradient were prepared by blending natural rubber with trans-1,4-polyisoprene and adjusting the amount of carbon black N 330. The physical and mechanical properties and dynamic mechanical properties of the blended vulcanizates were studied. The results showed that the comprehensive physical and mechanical properties of the blend with a carbon black amount of 20 phr (by mass) were relatively excellent. The melting temperature of trans-1,4-polyisoprene in the blend was estimated to be around 47 ℃ through dynamic mechanical analysis. The test results of the electro-hydraulic servo material tester showed that the natural frequency of the blend increased with the increase of carbon black amount and decrease of vibration amplitude and static compression load, and the ratio of dynamic and static stiffness increased with the increase of carbon black amount and static compression load.
