چکیده انگلیسی
Multiple-crosslinkable polyacrylate emulsion (MCPE) with high content of crosslinkable monomers was successfully synthesized via core-shell emulsion polymerization. Specially, cross-linkable monomers MAA and NMA were designed as the core layer monomers, vinyl triethoxysilane (A151) and epoxy resin (BC2060) were designed as the shell layer monomers, and aziridine (XR-100) was added as crosslinker. The hard core can be benefit for rapid drying of the film at room temperature, the soft shell can exhibit good film-forming ability. Epoxy resin was grafted on the chain of polyacrylate, which can endow excellent adhesion performance. The stability of MCPE was excellent and the core-shell structures of MCPE particles were maintained after stored for 15days at 50â¯Â°C, because those different crosslinkable monomers were introduced into different layers of the emulsion particles. The crosslinking density, tensile strength and glass transition temperature (Tg) of MCPE films were obviously higher than those of pure polyacrylate emulsion films due to the modification of several cross-linkable monomers. The MCPE ink film on PVC film has rapid surface drying performance, excellent adhesion and alcohol scrubbing resistance after multiple cross-linking at room temperature. All these advantages of this emulsion may contribute to its wide applications in the field of PVC film packaging and decoration.
