摘要

研究了废聚乙烯与高密度聚乙烯和低密度聚乙烯共混物在电子束辐照前后的动态力学性能。报道了辐射剂量对共混物的损耗模量、贮存模量和阻尼系数的影响。已观察到暴露于辐射后松弛温度升高。在暴露于辐射时也观察到峰展宽。随着辐照的增加，共混物的储存模量和损耗模量增大，而tan δ的储存模量减小。

Dynamic Mechanical Analysis of Electron Beam Irradiated Waste Polyethylene and its Blends with Virgin High Density and Low Density Polyethylene

Dynamic mechanical properties of blends of waste polyethylene and virgin high density as well as low density polyethylene have been investigated before and after exposure to electron beam irradiation. Effect of radiation dose on the loss modulus, storage modulus, and damping factor of the blends has been reported. An increase in relaxation temperatures on exposure to radiation has been observed. Peak broadening has also been observed on exposure to radiation. The storage modulus and loss modulus of the blends increase, while that of tan δ decreases on irradiation.

期刊介绍： The Journal of Elastomers and Plastics is a high quality peer-reviewed journal which publishes original research on the development and marketing of elastomers and plastics and the area in between where the characteristics of both extremes are apparent. The journal covers: advances in chemistry, processing, properties and applications; new information on thermoplastic elastomers, reinforced elastomers, natural rubbers, blends and alloys, and fillers and additives.
