摘　　要：通过不同流变仪对国产电子保护膜低密度聚乙烯(LDPE)专用料的流变性能进行了研究,并与进口电子保护膜LDPE专用料进行了对比。结果表明:2种电子保护膜的流变曲线相近,均具有假塑性流动行为;国产电子保护膜加工时,对温度进行调节,效果比较明显;进口电子保护膜加工时,对剪切速率进行调整,效果比较明显;与进口电子保护膜料相比,国产电子保护膜料的相对分子质量分布略宽,表观黏度低。The rheological properties of domestic low density polyethylene(LDPE)special materials for electronic protective film were studied by different rheometers,and compared with imported LDPE special material for electronic protective film.The results show that the rheological curves of the two materials are similar and both have pseudoplastic flow behavior.When processing domestic electronic protective film,the effect is obvious by adjusting the temperature.When processing imported electronic protective film,the effect is obvious by adjusting the shear rate.Compared with the imported electronic protective film materials,the domestic film materials have wider relative molecular weight distribution and low apparent viscosity.
