摘要
研究了不同配比的增黏剂、黏度调节剂、增塑剂和填充剂等对无规聚丙烯(APP)热熔胶性能的影响;以甲基丙烯酸甲酯(MMA)、丙烯酸丁酯(BA)和苯乙烯(St)等对APP进行熔融接枝改性,得到改性APP接枝物(即APP-g-St-MMA-BA);通过可视化优化法优选出制备APP热熔胶和APP-g-St-MMA-BA的最佳配方。结果表明:制备APP热熔胶的最佳配方为m(APP4型)∶m(APP5型)∶m(氢化C9树脂)∶m(轻质CaCO3)∶m(合成蜡)∶m(邻苯二甲酸二丁酯)=42.9∶57.1∶55∶14.0∶11.0∶3;制备APP-g-St-MMA-BA的最佳配方为m(APP5型)∶m(过氧化二异丙苯)∶m(MMA)∶m(BA)∶m(St)=20∶0.24∶2.16∶1.00∶1.24;APP-g-St-MMA-BA的耐热性能明显优于APP。
The influences of different ratio of tackifier,viscosity regulator,plasticizer and filler were investigated on performance of atactic polypropylene(APP) hot melt adhesive. With methyl methaerylate (MMA),butyl acrylate (BA) and styrene (St) as melting graft modifier of APP, so a modified APP grafted product (namely APP-g- St-MMA-BA) was obtained. The optimal formula of APP hot melt adhesive and APP-g-St-MMA-BA were preferred by visualized optimization method. The results showed that the optimal formula of APP hot melt adhesive was obtained when mass ratio of m (APP4 type ) :m (APP5 type) :m (hydrogenated C9 resin ) :m (light CaC O3) :m (synthetic wax):m(DBP) was 42.9:57.1:55:14.0:11.0:3 ,the optimal formula of APP-g-St-MMA-BA was obtained when mass ratio of m (APP5 type) :m (DCP) :m (MMA) :m (BA) :m (St) =20:0.24:2.16:1.00:1.24. The heat resistance of APP-g-St-MMA-BA was obviously better than of APP.
