The Study And Application Of Acrylate Copolymer Emulsion With Core-shell Structure

Acrylate copolymer emulsion adhesive and coating is one of the important application for emulsion polymerization. Based on the research status of Vinyl Acetate and Acrylate Copolymer Emulsion adhesive and Styrene-Butyl Acrylic emulsion coating; the emulsion copolymerization is performed according to molecule design theory. we optimize the synthesis technics and adjust the combination of monomer and get the Vinyl Acetate and Acrylate Copolymer Emulsion.we use it for coated fabric adhesive, and expect to solve the problem of Vinyl Acetate and Acrylate copolymer emulsion adhesive and develop the properties of copolymer emulsion adhesive.the measurements, such as TEM, FTIR, DSC and so on, are employed to characterize the struture of the product.we analyze and discuss some influencing factors, such as synthesis, protecting colloid, reaction times, initiator, emulsifier, copolymer monomer, polymerization technology such as stirring velocity, on the properties of acrylate copolymer emulsion adhesive.The main results include that: (1) We use the technics of seed emulsion polymerization combining and get low solid content Vinyl Acetate and Acrylate copolymer emulsion adhesive which is used in coated fabric .The costing of production has been reduced and the tensile strength has been increased. (2) Polymerization of Acetic/Acrylic micro soap-containing emulsion has been prepared with VAc,BA and MMA as monomers.The SVS reactive emulsifier, SDS andOP-10 emulsifier was used. The influence of ratio of soft monomer and hard monomer, kinds and levels of emulsifier, etc.
