摘要
主要研究了丁苯橡胶(SBR)与聚乙烯-乙酸乙烯酯(EVA)树脂在溶液中的接枝反应,并添加增黏树脂,制备出了具有较好黏结强度的粘接剂,讨论了EVA的加入量、反应时间和增黏剂加入量在相同SBR质量和溶剂的条件下,对胶液性能的影响,以及配方的选择。通过性能测试,最后得出溶剂型EVA改性SBR胶黏剂的合理制备工艺和配方:SBR5g、EVA6 25g、松香8g,反应时间3h,反应温度80℃。
Grafting-copolymer reactions between SBR and EVA in solvent were studied.Adhesive with high adhesion strength was prepared with the addition of tackifier.The influences of EVA resin, reacting time and temperature on the properties of adhesive were discussed when the SBR content and solvent type were constant.The optimal formula of EVA modified SBR glue and hot-melt adhesive was as follows:SBR 5g,EVA 6.25 g,rosin 8.0 g,reaction time 3h and reaction temperature 80℃.
