Title: Preparation of styrene-acrylate emulsion and latex particles impact on properties of emulsion
Abstract: A kind of styrene-acrylate emulsion with excellent performance was synthesized by styrene,butyl acrylate(as the main monomers)and acrylic acid(as the functional monomer)via mixed emulsifiers of SDS/OP-10 and ammonium persulfate served as the initiator.The pre-emulsification technology and semi-continuous seed emulsion polymerization process were introduced.The polymer emulsion was characterized by Fourier transform infrared(FT-IR)spectroscopy,differential scanning calorimetry(DSC),gel permeation chromatography(GPC)and nano-ZS90 etc.The effects of monomer ratio,composite emulsifier,polymerization temperature and the dosage of initiator on the emulsion film-forming properties,water resistance,stability and other conventional performance were systematically studied.The results showed that,the latex particle size was greatly influenced by composite emulsifier types and amount,but also related to the dosage of initiator.Monomer ratio was a key factor of the glass transition temperature.
