摘要:
以由3(甲基丙烯酰氧)丙基三甲氧基硅烷(MPS)表面修饰过的SiO2为无机粒子,聚己内酯二醇、甲基丙烯酸羟乙酯和异佛尔酮二异氰酸酯为聚氨酯(PU)前驱体,甲基丙烯酸甲酯、甲基丙烯酸和丙烯酸异辛酯为乙烯基共聚单体,通过一步细乳液聚合法制备接枝型聚丙烯酸酯(PAcr)/PU/SiO2纳米复合黏合剂。利用动态光散射、Zeta电位、傅里叶红外光谱、凝胶率、拉伸性能测试和差示扫描量热等表征方法系统研究了MPSSiO2用量对纳米复合黏合剂的颗粒特征、热性能和粘接性能的影响规律。结果表明:与PAcr/PU纳米复合黏合剂相比,MPSSiO2的引入使得PAcr/PU/SiO2纳米复合黏合剂粒子的尺寸增大,且粒子表面带较强的负电荷,储存稳定性好;表面乙烯基修饰的MPSSiO2能通过接枝反应参与黏合剂聚合物网络的形成,起到颗粒交联点的作用,使黏合剂聚合物的Tg相应地升高;在涂胶量为30 g/m2,烘焙温度1000 ℃时,添加07 wt%的SiO2使得胶膜的断裂强度提高87%,断裂伸长率提高200%,剥离强度提高51%,获得了更优的综合粘接性能。
