The core-shell acrylate emulsion was prepared with methyl methacrylate (MMA), styrene (St) and butyl acrylate (BA) as the main monomers and silane coupling agent as the modified monomers. The structure was designed and the influence of crosslinked monomer on the properties of emulsion was investigated in the study. The results showed that the stability and film formation of the emulsion were better when the amount of styrene is 15%(based on the total mass of all monomers, the same below), the theoretical glass temperature of the core layer and the shell layer were -10 ℃ and 30 ℃, and the amount of the core layer cross-linked monomer vinyltriethoxysilane (A-151) and the shell layer cross-linked monomer gamma-methacryloxy propyl trimethoxysilane (A-174) is 3% and 2%, respectively. Compared with the homogeneous particle structure without crosslinked monomer, the maximum thermal adhesion temperature of the core-shell structure polymer is increased by 90 ℃, the water absorption rate is reduced by 10.8%, and the thermal decomposition temperature (mass loss of 5%) is increased by 38 ℃, alleviating the high-temperature adhesion problem of ink coatings and improving the water and heat resistance of the coating film.
