Definition of architectural coatings , composition , classification , function and history of the development was elaborated in detail . Systematic exploration of acrylic emulsion polymerization process , the reaction conditions , monomer ratio , initiator and emulsifier emulsion performance . The experimental results show that , using the redox initiator system, the reaction temperature than the thermal decomposition temperature of the initiator system reaction greatly reduced . For the same film-forming temperature requirements emulsion , acrylic emulsion hardness monomer ratio : BA ; of MMA = 4:5 ; styrene-acrylic emulsion , BA: St = 5:4 . This article focuses on the report of silicones and organic fluorine modified acrylic emulsion , aims to develop a high-performance environmentally friendly exterior paint work . Acrylic latex paint for its environment-friendly , with better color retention , weather resistance and high adhesion , welcomed and respected by the majority of users and can dry at room temperature . Thermoplastic acrylic resin itself limited , linear molecules lack of cross-linking point , it is difficult to form a crosslinked film of the three-dimensional mesh , its poor temperature resistance , high temperature return YS , low temperature and lack of flexibility , the coating becomes brittle and easy to fall off . For the above reasons , this paper investigates the silicone and organic fluorine chemical modification of acrylic emulsion . The kind of an organic silicon and an organic fluorine monomer , the influence of the modified method, modified monomer added in an amount such factors emulsion performance . And infrared spectroscopy , thermogravimetric and X-ray photoelectron spectroscopy to characterize the emulsion structure and performance . Study found that the modified acrylic emulsion , acrylic latex and silicone acrylic emulsion latex membrane water resistance , adhesion and surface properties than . The article also includes a latex paint production process methods , emulsion , pigments, additives and process on the performance of latex paint , and developed a performance organic silicon , organic fluorine modified acrylic latex paint , all the performance has been tested are to meet or exceed current national the standard ( GB/9755-2001 ) .
