Abstract

The methyl acrylate was modified with hexafluorobutyl methacrylate (G02) and vinyl triethoxy silane (A-151) as modified monomers, Methyl Methacrylate (MMA) as hard monomer and Butyl Acrylate (BA) as soft monomer. Pre-emulsification, seed emulsion and semi-continuous synthesis process were adopted to the effects of the preparation process, the ratio of G02 and A-151 modified monomers, the amount of soft monomer and hard monomer on product performances. The structure of the modified acrylate was characterized by infrared spectroscopy (FTIR). The thermal stability of the product was determined by the Thermo Gravimetric Differential Thermal Analyzer (TG-DTA). It was showed that the water absorption of the paint film prepared by using the optimized formula was 5.1%, the adhesion of the surface layer of the tinplate was grade 1, the tensile strength of the latex film layer was 2.13 MPa and the elongation of the high elastic resin was 736%. The organic fluorine-silicon and monomers were successfully grafted onto the acrylic polymer, the low fluorine high performance fluorine/silicon co-modified elastomeric acrylate was successfully prepared. Compared with other silicone and fluorine modified acrylate, the product has better thermal stability and tensile strength, improved cost-effectiveness of this type of exterior coating.
