摘要
乙烯-醋酸乙烯共聚物(EVA)具有优异的柔韧性、耐腐性、加工性、绿色环保,广泛应用于薄膜、热熔胶、黏合剂、电线电缆等领域.然而,EVA存在粘度低、热性能和力学性能差等缺点,限制了其发展和应用.因此,制备性能优良的新型改性EVA材料成为近年来的研究热点.本综述回顾了近年来关于EVA不同改性方法的研究进展,对化学改性和物理改性两方面进行了重点介绍,分析了不同改性方法的优势和短板,最后对EVA改性方法及研究方向进行展望.
Abstract
Ethylene vinyl acetate copolymer(EVA)has excellent flexibility,corrosion resistance,processability,non-toxicity,and environmental friendliness.It is widely used in various fields such as films,hot melt adhesives,adhesives,wire,and cable.However,EVA has disadvantages such as low viscosity,and poor thermal and mechanical properties,which limit its development and applications.Therefore,the preparation of new modified EVA materials with excellent performance has become a research hotspot in recent years.This review summarizes the research progress on different modification methods of EVA,focuses on both chemical and physical modification,analyzes the advantages and disadvantages of different modification methods,and finally looks forward to EVA modification methods and research directions.
