Study on synthesis of core-shell type of styrene-acrylate emulsion with silicon

The core-shell type of styrene-acrylate emulsion with silicon was synthesized with methyl and KH-560 as the shell monomers. The influence of proportion of soft-hard monomers,the contents of emulsifier,initiator and cross linker KH-560 on the performance for emulsion or film were studied by la-(FT-IR)and transmission electron microscope(TEM). The research results showed the stability of styser particle size analyzer,differential scanning calorimetry(DSC),Fourier transform infrared spectroscopy reneacrylate emulsion with silicon was better,the average particle size was small,and distribution of particle size was narrow,the moderate crosslinked emulsion or film could improve water resistance and hardness when the mass ratio between BA and St and MMA was 1.5∶0.5∶1.0,the mass fraction of initiator,KH-560 was 0.5%,3.0% and 16% respectively.
