摘　　要：研究增塑剂种类及用量对氢化丁腈橡胶(HNBR)性能的影响。结果表明:采用增塑剂TP-95的HNBR胶料的t_(10)和t_(90)较短,相应硫化胶具有较好的耐低温性能;采用增塑剂DOS的HNBR硫化胶具有较大的硬度和拉伸强度以及良好的耐油性能;随着增塑剂用量的增大,HNBR胶料的门尼粘度明显下降,硫化胶的耐低温性能改善;当采用20份增塑剂DOS时,HNBR硫化胶具有较好的物理性能和耐油性能,同时具有较好的耐低温性能。The effects of plasticizer types and dosage on the properties of hydrogenated nitrile rubber(HNBR)were studied.The results showed that the t_(10) and t_(90) of HNBR compound using plasticizer TP-95 were shorter,and the corresponding vulcanizates had good low-temperature resistance.The vulcanizates using plasticizer DOS had high hardness,high tensile strength and good oil resistance.With the increase of plasticizer dosage,the Mooney viscosities of HNBR compounds decreased significantly,and the low temperature resistance was improved.When the dosage of plasticizer DOS was 20 phr,the HNBR vulcanizate had good physical properties and oil resistance,as well as good low temperature resistance.
