Embodiment 1
[0042] Step 1: Preparation of Adhesive
[0043] Preparation of core-shell emulsion: the core layer emulsifier fatty alcohol polyoxyethylene ether (AEO-9), deionized water and methyl methacrylate (MMA), ethyl acrylate (EA) and n-butyl acrylate (BA) Add it into a 500mL four-neck flask, ultrasonicate at 55°C for 15min, then raise the temperature to 58°C, stir at 580r / min for 45min to disperse evenly, and obtain the core layer pre-emulsion; the shell layer emulsifier (AEO- 9), deionized water, methyl methacrylate (MMA), ethyl acrylate (EA) and n-butyl acrylate (BA) were added to a 500mL four-necked flask, ultrasonicated at 55°C for 15min, and then heated to 58°C , stirred at 580r / min for 45min to disperse evenly to obtain a shell pre-emulsion.
[0044] Add 0.4 g of ammonium persulfate (APS) to 10 mL of water to configure the initiator solution, separate 5 mL into the syringe pump, and add the core layer pre-emulsion to the dropping funnel (reserve about 1 / 4 in the original flask). ...
