Motivated by the globally increasing concern over environmental protection, the interest of a large part of the scientific community focuses on the development of green surfactants aiming to replace traditional toxic surfactants based alternatives. The purpose of the present study was to prepare acrylate copolymer latex modified with fluorine and silicone monomer, which is emulsified with the green surfactants of sodium rosinate and APG.
A series of acrylic copolymer latexes containing fluorine-silicon have been prepared by semi-continuous seed emulsion polymerization of mixed monomers of methyl methacrylate (MMA), butyl acrylate(BA), hexafluorobutylmethacrylate (HFMA) and vinyltriethoxysilane (VTES) and emulsified by green mixed surfactants of sodium rosinate and alkyl polyglycoside (APG).
The optimum recipe of preparing the emulsion is as follows: the amount of emulsifiers is 6% and the mass ratio of sodium rosinate to APG is 1:3. The amount of initiator is 0.4% and the amounts of the silicon monomer and fluorine monomer were 5% and 7%, respectively. In comparison with the acrylate latex prepared without fluorine monomer and silicon monomer, the thermal stability and the water resistance of the film of the resultant latex were clearly improved.
The acrylic copolymer latexes containing fluorine-silicon emulsified with green surfactants can be used in the coatings, adhesives, finishing agengts and so on.
