Embodiment 1
[0012] formula:
[0013]
[0014] Manufacturing process:
[0015] (1), add 450 kg of distilled water, start stirring, and slowly add polyvinyl alcohol (15 kg for 1788 model, 25 kg for 0588 model) in order.
[0016] (2) Put in sodium acetate and water-based defoamer, start to heat the reactor to 90 degrees Celsius, when the temperature is stable and maintain this temperature for 30 minutes, then drop to 70 degrees Celsius, add sodium lauryl sulfate and OP-10 , allow it to be fully emulsified, drop into methanol after 10 minutes, and put into initiator ammonium persulfate 0.04% (weight ratio) simultaneously, after 10 minutes, slowly drop the mixed vinyl acetate, acrylic acid, and butyl acrylate into the reactor.
[0017] (3), setting time is 4 hours, adds 0.05% (weight ratio) ammonium persulfate once every 30 minutes simultaneously, till adding.
[0018] (4) At this time, the heating reaction kettle is in a sealed state, and the steam in the reaction kettle is discharged in...
