摘要

摘要: 通过分析结合胶离解温度曲线,研究填料与橡胶之间的作用力。采用溶剂法分别制得6种不同填料的结合胶,探索结合胶的最佳解离时间,分析结合胶微观形貌结构、热胀离解温度及硫化后的宏观性能。结果表明,白炭黑在常温下体现出优异的补强性能,但在高温下的键能较弱;高结构炭黑在低温至高温下都表现出优良的补强性和成键稳定性,且硫化胶具有最优的定伸应力和拉伸强度;普通炭黑在低温和高温下的各项性能都处于中等,但在超高温下,其补强性能表现最为优异。

Abstract: White silica powder, low-structure and high-structure carbon blacks were used as fillers for rubber and were incorporated into them by dry or solvent-aided mixing methods. The bonding strength between filler and rubber was investigated by AFM, mechanical tests and a bonding test using solvent extraction with xylene. Results indicate that the silica has an excellent reinforcing performance at normal temperature, but the bond energy is weakened at high temperatures. High-structure carbon blacks exhibit excellent reinforcement and bonding stability at low to high temperatures, and vulcanized rubbers have the highest tensile strength and can withstand the highest tensile stress, and are considered the best fillers. Low-structure carbon blacks show an intermediate reinforcing performance between the silica and the high-structure carbon blacks, but their reinforcement is best at ultra high temperatures.
