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。
