【Abstract】 The compatibility between the selective resin vulcanization reagent and the Butyl rubber(IIR) was studied through the DSC methods, the results show the compatible relationship between the two. The damping mechanics properties of the IIR/the resin vulcanization reagents compound materials system was studied by Dynamic Mechanical(DMA) methods, The results show that the efficient temperature region and the temperature point of the max Loss Tangent(tanδmax) increase with increasing amount of the resin vulcanization reagents, while the Store Modulus(E’) and the Loss Modulus(E") decrease, the wasting factorial(tanδ) acts the decreasing trends in the first parts, reach the peak value in sucession and decrease at the latter parts, this results different from the reference’, the damping action mechanism of the resin vulcanization reagents on the compound material system was analyzed and discussed at the same time.更多还原
