摘要
研究充环烷油的高乙烯基聚丁二烯橡胶的流变性能、物理性能及动态力学性能。结果表明:充油后生胶的门尼粘度明显下降,剪切粘度随剪切速率的增大而减小;胶料的t10和t90变化不大,交联密度减小;硫化胶的主要物理性能下降,压缩生热和永久变形降低,抗湿滑性能和耐老化性能提高;随着频率的增大,硫化胶的剪切储能模量(G′)、剪切损耗模量(G″)和损耗因子(tanδ)增大,随着应变的增大,G′减小,G″和tanδ先增大后减小,玻璃化温度升高。
The rheological properties, physical properties and dynamic properties of high vinyl polybutadiene rubber extended with naphthenic oil were investigated. The results showed that, the Mooney viscosity of the rubber extended with naphthenic oil decreased significantly,and the shear vis- cosity decreased with the increase of shear rate. The tl0 and tg0 of the compound changed little,and the crosslink density decreased. The main physical properties of the vulcanizate decreased, the compression heat build-up and permanent set decreased, the wet skid resistance and aging resistance were im- proved. As the frequency increased,the shear storage modulus（G＇）,shear loss modulus（G＂） and loss factor（tanδ） of the vulcanizate increased. As the strain increased, the G＇ decreased,G＂ and tanδ in- creased at first and then decreased, and the glass transition temperature increased.
