Embodiment 1
[0035] 1. Preparation of zinc ion crosslinked core-shell acrylic ionomer emulsion
[0036] (1) Preparation of styrene-acrylic copolymer core emulsion: Add 30 parts of distilled water, 5 parts of compound emulsifier (1 part of OP-10, 4 parts of sodium lauryl sulfate) and 1 part of potassium persulfate into a three-necked flask , stirred at 80°C for 20 min; then 1 part of initiator solution, 5 parts of methacrylic acid, and 15 parts of styrene were added dropwise to the reaction system within 1.5 h, and the polymerization reaction was carried out under stirring for 1 h to obtain the styrene-acrylic copolymer core Lotion;
[0037] (2) Preparation of core-shell acrylic ionomer emulsion: A solution of 20 parts of methacrylic acid, 10 parts of methyl methacrylate, 5 parts of butyl acrylate and 3 parts of potassium persulfate was added dropwise to the above core within 1.5 h. in the emulsion, and then polymerized for 1 h to obtain a core-shell acrylic ionomer emulsion;
