摘　　要：以EVA树脂为主体树脂制备钢质管道防腐用热熔胶,选用聚合松香为增粘剂,聚异丁烯为增韧剂,研究了不同VA含量、不同熔体指数的EVA树脂、聚合松香及聚异丁烯对热熔胶环球软化点、脆化温度和剥离强度等性能的影响。In this paper,hot-melting adhesive （HMA） was prepared by EVA/ polymerized rosin/ PIB composite for corrosion protection of steel pipeline,which EVA resin,polymerized rosin and PIB were selected as main resin,tackifier and toughening agent separately. The effect of EVA with different content of VA and different melt index polymerized rosin and PIB on properties of HMA such as R＆B softening point,brittleness temperature and peel strength were studied.
