摘　　要：加成型液体硅橡胶(ALSR)是硅氢加成反应在硅橡胶固化交联领域中的一个重要应用。因为是加成交联,ALSR在固化过程中不产生副产物,收缩率极小,能深层固化且对接触的材料无腐蚀,所以加工成型时无气泡、砂眼,尺寸稳定,具有优良的耐热冲击性能,在诸多领域有着重要应用价值。本文首先简述了ALSR的基本组成与固化机理,然后以性能为切入点综述了近年来ALSR在机械、导热、粘结和阻燃等性能方面的研究进展,以及在电子电气、医疗、3D打印、光学和汽车领域的应用,最后提出高性能、多功能、复合化和先进加工是未来ALSR的发展方向。Addition liquid silicone rubber(ALSR)is an important application of hydrosilylation addition reaction in the field of silicone rubber curing and crosslinking.As it is crosslinked by addition,ALSR does not produce by-products during the curing process,has very small shrinkage,can be deeply solidified,and has no corrosion to the materials in contact.Therefore,there are no bubbles and sand holes during processing and molding,with stable size,excellent heat shock resistance,and has important application value in many fields.This article first outlines the basic composition and curing mechanism of ALSR,and then reviews the research progress in mechanical,thermal,adhesive,and flame retardant properties of ALSR in recent years,as well as its applications in the fields of electronic and electrical,medical,3D printing,optical,and automotive.Finally,it proposes that high-performance,multifunctional,composite,and advanced processing are the future development directions of ALSR.
