从相对分子质量、玻璃化转变温度和物理机械性能等方面研究了日本瑞翁公司生产的AR71与国产AR81和AR1000。结果表明,AR71的相对分子质量最高且分布最窄,AR1000的相对分子质量分布最宽。AR71和AR81的玻璃化转变温度接近,但都低于AR1000。AR71生胶门尼粘度最高,AR1000混炼胶门尼粘度最高。炭黑填充AR71的Payne效应最明显,但分散较差。采用皂-硫黄硫化体系时,AR71的硫化程度最高,硫化速度最快,AR81的硫化程度最低。AR71硫化胶的有效阻尼温域最宽,AR1000的最窄。
From the relative molecular mass, glass transition temperature and physical and mechanical properties and other aspects of the research and development of AR71 produced by Japan Zeon and domestic AR81 and AR1000. The results showed that the relative molecular mass of AR71 was the highest and its distribution was the narrowest, and AR1000 had the widest molecular weight distribution. The glass transition temperatures of AR71 and AR81 are close but lower than that of AR1000. AR71 raw rubber Mooney viscosity highest, AR1000 rubber mixing Mooney highest viscosity. The Payne effect of carbon black filled AR71 was most pronounced, but poorly dispersed. With the soap-sulfur cure system, the AR71 has the highest degree of cure, the cure rate is the fastest, and the AR81 is the least vulcanized. AR71 vulcanizates the most effective damping temperature range, AR1000 the narrowest.
