Abstract

The present study describes the effect of thermo, thermo-oxidative, and ozone exposure on the retention of physical property of organoclay nanocomposites. Accelerated thermal aging is carried out at 130°C for 30 h. Accelerated thermo-oxidative aging is carried out at 105°C for 7 days. Samples are exposed to 50 pphm ozone atmosphere for 24 and 48 h. The result indicates that the retention of physical property is better in nanocomposites compared to carbon black-filled compounds under thermal and thermo-oxidative aging. Besides, ozone resistance is also relatively superior for nanocomposites. The superior barrier property of the nanocomposites is attributed to the better retention of the physical property after aging.
臭氧、热、热氧化老化对丁苯橡胶-有机粘土纳米复合材料物理性能的影响
本研究描述了热、热氧化和臭氧暴露对有机粘土纳米复合材料物理性质保持的影响。在130℃加速热老化30 h。在105℃加速热氧化老化7天。将样品在50 pphm的臭氧环境中暴露24和48 h,结果表明,在热老化和热氧化老化下,纳米复合材料的物理性能保持优于填充炭黑的复合材料。此外,纳米复合材料的耐臭氧性能也相对优越。纳米复合材料优异的阻隔性能是由于其在时效后的物理性能保持较好。
