Embodiment 1
[0056] Table 1 Monomer formula of paper-plastic composite adhesive emulsion E1 (unit: g)
[0057]
[0058] Note: HA refers to the mixture of glycidyl methacrylate and acrylamide with a mass ratio of 1:1
[0059] resolve resolution:
[0060] Preparation of nuclear emulsion: first pre-emulsify 30 g of deionized water, 0.3 g of nonylphenol polyoxyethylene (10) ether ester disodium sulfosuccinate (MS21), and core layer monomer phase I to obtain pre-emulsion A; 0.4g of ammonium persulfate (APS) is prepared into an initiator solution D (APS solution D) with a concentration of 3% by weight; 0.15g of diacid block is prepared into an aqueous solution E with a concentration of 10 to 20% by weight. Add 15g of deionized water, 0.3g of buffering agent sodium bicarbonate, and 10% of the weight of APS aqueous solution D to the four-necked flask to prepare the base material, raise the temperature to 78°C, add 3% of the total weight of the pre-emulsion A of 3% by weight to react to form S...

[0066] Table 2 Monomer formula of paper-plastic composite adhesive emulsion E2 (unit: g)
[0067]
[0068] resolve resolution:
[0069] Preparation of nuclear emulsion: first pre-emulsify 32g deionized water, 0.25g ethoxylated alkyl ether ammonium sulfate (CO-436), and nuclear layer monomer phase I to obtain pre-emulsion A; take 2,2-azo 0.4 g of diisobutylamidine dihydrochloride ammonium (V50) was used to prepare an aqueous solution D with a concentration of 3% by weight; and 0.15 g of sodium bisulfite was prepared to prepare an aqueous solution E with a concentration of 10-20% by weight. Add 12g deionized water, 0.3g buffering agent sodium bicarbonate, and 10% of the total weight of APS aqueous solution D to the four-necked flask to prepare the base material, raise the temperature to 75°C, add 8% of the total weight of pre-emulsion A to react to form a seed emulsion; Raise the temperature to 78°C, start to add the remaining pre-emulsion A dropwise, and simultaneously add ...
