Embodiment 1
[0033] Preparation of water-based reactive acrylate microgel emulsion:
[0034] (i) Preparation of pre-emulsified monomer mixture: add 0.25g N, N-methylenebisacrylamide, 32g butyl acrylate, 7.0g hydroxyethyl acrylate, 0.75g OP-10, 0.5g Acrylic acid and 20ml of deionized water were stirred at high speed for 10 minutes to fully pre-emulsify.
[0035] (ii) Preparation of initiator: Add 0.25 g of ammonium persulfate and 14.75 ml of deionized water mixture into a beaker.
[0036] (iii) Preparation of the reaction bottom liquid: In a three-necked flask equipped with a stirrer, a condenser, and a constant temperature water bath, add 2.0 g of self-made amphoteric surfactant, 1.0 g of Aerosol-OT, 0.75 g of OP-10, and 0.25 g of bicarbonate Sodium, 60ml deionized water. Stir mechanically and slowly raise the temperature to 87°C.
[0037] (iv) Preparation of water-based reactive acrylic microgel: move the pre-emulsified mixed monomers into the dropping funnel and slowly drop them into ...
