Synthesis and Properties of Silicone Modified Acrylate Emulsion

Xia Zhen Zhang, Pei Wang, Lian Liu, Jian Xiong

Abstract

Silicone modified acrylate emulsion was successfully synthesized by pre-emulsion polymerization with the monomers of butyl acrylate(BA), methyl methacrylate(MMA), acrylic acid(AA), vinyl triethoxy silane(DB-151) using APS as initiator. The influence of reaction temperature, emulsifier system and silicone concentration on emulsion properties was discussed. The results showed that the overall performances of obtained emulsion became better with the condition: the reaction temperature 75°C, 6%~8% of silicone concentration, and 3% complex emulsifier system consist of the non-ionic /anionic/amphoteric emulsifier. The study also proved that silicone modified acrylic emulsion can improve water resistance and hardness of the resin.
