【摘要】 本工作对镍系充油顺丁橡胶 DJ-9073(充油25份)和DJ-9075(充油 37.5份)的结构及其炭黑混炼胶的流变行为进行了探讨,并与未充油的镍系顺丁橡胶DJ-9000和日本产充油37.5份的镍系充油顺丁橡胶 BR-31进行了比较和讨论。结果表明,国产充油顺丁橡胶的辊筒加工行为优于DJ-9000和 BR-31。DJ-9075的综合流变性能好于 DJ-9073。在高切变速率下,四种胶料的流动性接近。更多还原

【Abstract】 The structure of oil-extended cis-1,4-polybutadiene rubbers DJ-9073 (with 25 parts of extend oil ) and DJ-9075 ( with 37.5 parts of extend oil ), both manufactured by Shengli Chemical Works of Yanshan Petro chemical Industry Corporation with nickel catalyst system, and the rheol-ogical behaviour of their carbon black compounds were studied with referenc to their un-extended counterpart DJ-9000 and oil-extended cis-1,4-polybu-tadicne rubber BR-31 ( with 37.5 parts of extend oil, and produced in Japan ) by nickel catalyst system. The results show that the rollability of DJ-9073 and DJ-9075 are superior to that of DJ-9000 and BR-31;and the rheological property of DJ-9075 is better than that of DJ-9073. But under higher shear rates, the flow curves of these four rubbers are essentially identical.更多还原
