研究了氯丁橡胶(CR)/三元乙丙橡胶(EPDM)共混胶的两相交联密度与其储能模量之间的关系并建立了拟合模型,考察了共混胶中各组分的交联密度、储能模量及应力松弛性能三者之间的关系。结果表明,该模型的适用温度范围为35~80 ℃,两相交联密度与储能模量呈线性相关。当m(CR)/m(EPDM)为70/30时,CR/EPDM共混胶的储能模量模型预测值与实测值接近,证明模型具有较高的可靠性。CR相对共混胶总储能模量的影响程度较大。共混胶的应力松弛性能与各组分的交联密度及储能模量均呈线性关系。
- Abstract:
-
The relationship between crosslinking density and storage modulus of chloroprene rubber (CR) / ethylene-propylene-diene rubber (EPDM) blend was studied and the fitting model was established. The relationship between the crosslinking density, storage modulus and stress relaxation properties of each component in the blended rubber was also investigated. The results showed that the applicable temperature range of the model was 35-80 ℃ and the crosslinking density of the two phases were linearly related to the storage modulus. When m(CR)/m(EPDM) was 70/30, the predicted value of the storage modulus model of CR/EPDM blend was close to the measured value, which proved that the model had high reliability. The effect of CR phase on the total storage modulus of CR/EPDM blend was greater. The stress relaxation property of the blend had a linear relationship with the crosslinking density and storage modulus of each component.
