【摘要】 研究了不同硫化体系和不同无机填料对丁腈橡胶Ｎ４１在１００℃高温下的压缩永久变形的影响。结果表明，ＤＴＤＭ有效硫化体系硫化胶的压缩永久变形最小；ＤＣＰ过氧化物硫化体系次之；ＣＺ有效硫化体系较差；硫黄硫化体系最差。无机填料填充的胶料中，以添加石英粉的胶料压缩永久变形最小，而且用量增加其变形值变化不大，此外是氧化铁红、超细碳酸钙、白炭黑２３３Ｎ和２５５Ｎ。更多还原

【Abstract】 The influence of different curing systems and inorganic fillers on the compression set of NBR N41 at 100℃ was studied. The results showed that DTDM EV system was the most effective in terms of the minimum compression set of the vulcanizate;DCP was more effective;CZ EV system was poor; and sulfur curing system was the most poor. Among the inorganic fillers,the quartz filler was the most favourable to the minimum compression set of the vulcanizate, and the compression set would change little with the increase of the quartz filler level;the other favourable inorganic filler were put in the order of iron oxide red,super-fine calcium carbonate and silica 233N and 255N.更多还原
