摘　　要：添加自制爽滑母料制备了流延聚丙烯(CPP)热封膜,并研究了薄膜电晕面和非电晕面摩擦因数的变化。结果表明:厚度相同的薄膜在高温加热24 h与常温放置30天的电晕面摩擦因数基本相同,可使用薄膜高温所测的摩擦因数模拟常温放置时的摩擦因数变化;与添加某进口爽滑母料生产的CPP热封膜相比,添加自制爽滑母料生产的CPP热封膜的摩擦因数在放置过程中随着时间的延长而降低,效果优于添加进口爽滑母料生产的薄膜,且各项性能指标均能满足国家标准要求。The cast polypropylene(CPP)heat sealing film was prepared by adding the self-madeslipping masterbatch.The changes in friction factor of corona surface and non-corona surface of the filmwere investigated.Results show that the friction factor of corona surface of the films which are heating at hightemperature for24hours are equal to that of the film in same thickness laying at room temperature for30days,which means the friction factor measured at high temperature can be used to simulate the variation of the factor atroom temperature;the friction factor of CPP film made of homemade masterbatch decreases with time comparedwith that of imported material,and the properties of the film meet the requirements of national standard.
