Embodiment 1
[0032] The formula for preparing masking paper adhesive is as follows:
[0033] 300 parts of butyl acrylate,
[0034] 100 parts of isooctyl acrylate,
[0035] 2 parts acrylic,
[0036] 2 parts of hydroxyethyl acrylate,
[0037] 40 parts of styrene-acrylic emulsion,
[0038] 6 parts of sodium benzenesulfonate,
[0039] 450 parts of water,
[0040] 4 parts ammonium persulfate,
[0041] 0.2 parts of sodium bicarbonate.
[0042] The specific preparation method is as follows:
[0043] a. Add 85% sodium benzenesulfonate in the formula to the pre-emulsification kettle, mix with 45% water and stir evenly, and add all butyl acrylate, isooctyl acrylate, acrylic acid and hydroxyethyl acrylate in the formula Esters, stir evenly to make a pre-emulsion;
[0044] b. Add all the sodium bicarbonate, 55% water and all the remaining sodium benzenesulfonate in the formula to the reaction kettle; heat up to 85°C, add 70% ammonium persulfate, and all the styrene-acrylic emulsion;
