Embodiment 1
[0032] (1) Preparation of AM mixture:
[0033] Synthesis of acrylate monomer emulsion: add 6g sodium lauryl sulfate, 3g potassium persulfate, 100g deionized water into the reaction kettle, stir and pass nitrogen, add 225.6g methyl methacrylate, 56.4 g butyl acrylate with Na 2 SO 4 The pH value of the emulsion is adjusted by the solution to 8, and the temperature is kept at 50° C. for 2 hours, and the temperature is lowered to obtain an acrylate monomer emulsion;
[0034]Preparation of AM mixture: Add 200 g of deionized water, 12 g of sodium lauryl sulfate, 12 g of potassium persulfate and 818 g of acrylate monomer emulsion prepared in the previous step into a stainless steel autoclave, containing 282 g of acrylate monomer, Use 5% to 10% NaOH solution to adjust the pH value of the mixed reaction solution in the range of 9 to 11, then add 18g of crosslinking agent DCP and silane coupling agent KH-560, fill with nitrogen, vacuumize and exhaust oxygen, repeat 3 times, then add ...
