摘　　要：采用原位聚合制备了纳米SiO2/聚丙烯酸酯复合乳液,研究了SiO2的用量对成膜时间、光泽度、吸水倍率、机械及耐酸碱性能和热性能的影响。结果表明添加纳米SiO2后,可以显著降低聚合物乳液的成膜时间,提高胶膜的附着力和硬度、胶膜的抗冲击强度、膜弹性和耐热分解性能。The nosilica/acrylic compound latex prepared by in-situ polymerizarion method,and the effect of the film forming time,gloss,water absorption rate,mechanical,acid-resistant,alkail-resistant and thermal properties of the latex film were studied.The results showed that the film forming time of the latex film reduced apparently,that the adhesion force and the hardness increased and that the impact strength,elastic,heat decomposition properties of the latex film also were improved.
