本文研究了试验温度和速度对加炭黑氯丁胶与黄铜粘接性能的影响。结果表明:当不加硫磺氯丁胶样品与黄铜粘接时,在所有试验温度和速度下都出现界面破坏,且界面破坏能 Gi 随着试验温度的降低而增加,随着试验速度的增加而增加。当含有0.5份以上硫磺的氯丁胶样品与黄铜粘接时,在-10℃以上的所有试验温度和速度下都出现橡胶层的内聚力破坏,且内聚力破坏能 G_c 随着试验温度和硫含量的增加而减少。在较低硫含量的样品或较低试验温度时,G_c 随着剥离速度的增加而减小。这一现象可能是由于橡胶的应变诱导结晶所致。
The effect of test temperature and speed on the adhesion of carbon black neoprene with brass was studied in this paper. The results show that when the sample is not bonded with brass, the interface failure occurs at all the test temperatures and velocities, and the interface damage Gi increases with the decrease of the test temperature. With the increase of test speed Increase. When a sample of neoprene containing more than 0.5 part of sulfur is bonded to brass, the cohesive failure of the rubber layer occurs at all the test temperatures and speeds of -10 ° C. or higher, and the cohesive failure energy G_c decreases with the test temperature and the sulfur content Increase and decrease. G_c decreases with increasing peel speed for lower sulfur content samples or lower test temperatures. This phenomenon may be due to strain induced crystallization of rubber.
