摘    要:采用半连续乳液聚合法,将八硝苯基笼型倍半硅氧烷(ONPS)掺入(甲基)丙烯酸酯乳液中,对其进行改性。透射电镜照片、粒径分布分析、DSC、拉伸强度的测量结果表明:ONPS的加入量低于3%时,明显提高了丙烯酸酯树脂的Tg,同时乳液涂膜的拉伸强度大幅上升,而断裂伸长率略有下降。

关 键 词:八硝苯基笼型倍半硅氧烷  丙烯酸酯乳液  分散  力学性能  热性能

Abstract:The octa(nitrophenyl)silsesquioxane(ONPS)-modified acrylate emulsion is synthesized by a semi-continuous polymerization in this paper.Analysis by TEM and the particle size distribution show that the ONPS particles are homogeneously dispersed in the emulsion at a nanometer scale.Differential scanning calorimetry test shows that the addition of ONPS increases T_g of acrylate emulsion significantly,as well as the tensile strength of films,but decreases rupture elongation slightly.
Keywords:octa(nitrophenyl)silsesquioxane  acrylate emulsion  dispersion  mechanical properties  thermal properties
