| The work aims to prepare the multi-component copolymer acrylate emulsion, and apply it in the paper-plastic composite film. Emulsion copolymerization was carried out to optimize the synthetic process and prepare the acrylate emulsion adhesive. In the optimal process conditions for the preparation of adhesive, the mass ratio of SDS and emulsifier OP-10 was 1∶3, the total mass fraction was 4.5%; the mass fraction of ammonium persulfate (initiator) was 0.6%; the mass fraction of acrylic acid was 5%; the mass ratio of BA and VAC was 13∶6 and the mass fraction of zinc acetate was 0.2%. The pre-emulsified seed dropping method was selected. The pre-emulsification time was 30 min, the temperature was 50 ℃, and the stirring speed was 440 r/min. The stirring speed of dropping and holding time was 400 r/min, the holding time was 1 h, the monomer dropping time was 3 h, the dropping temperature was 80 ℃ and the holding temperature was 83 ℃. At the end of the reaction, the hydroquinone was added and the mass fraction was 0.3%. The synthesized adhesive has good bonding performances. |
