研究液体邻苯二甲酸正辛正癸酯（810酯）/固体古马隆树脂并用比对氢化丁腈橡胶（HNBR）性能的影响。结果表明：810酯的增塑效果比古马隆树脂好；随着810酯/古马隆树脂并用比（总用量12份）减小，胶料的焦烧时间变化不大，硫化速度加快，硬度、拉断伸长率和粘合性能提高，拉伸强度略有下降，定伸应力和耐热老化性能先提高后降低；810酯/古马隆树脂并用比为8/4时，胶料的综合性能较好。

In this study, the influence of blending ratio of liquid n-octyl-n-decyl phthalate (ester 810) and Coumarone resin on the properties of HNBR was investigated. The experimental results showed that the ester 810 provided better plasticizing effect than Coumarone resin for HNBR. With a decrease of the ratio of ester 810/Coumarone resin, while the total amount was maintained at 12 phr, the scorch time of HNBR changed little, the curing speed increased, the hardness, elongation at break and adhesion properties of the vulcanizates also increased, the tensile strength decreased slightly, the tensile modulus and heat aging properties firstly increased and then decreased. The overall properties of HNBR were optimized when the ratio of ester 810 and Coumarone resin was 8/4.
