Embodiment 1
[0041] The proportioning in parts by mass of the long-chain unsaturated fatty acid modified acrylate emulsion of the present embodiment is as follows:
[0042] Butyl acrylate 40; methyl methacrylate 40; oleic acid 0.8; potassium persulfate 0.4; sodium lauryl sulfate 0.6; nonylphenol polyoxyethylene ether 1.8; sodium bicarbonate 0.4; water 120.
[0043] The preparation method is as follows:
[0044] a Proportionally weigh 1 / 5 of the butyl acrylate and methyl methacrylate, 1 / 2 of the water, 1 / 3 of the potassium persulfate, sodium lauryl sulfate and nonyl Base phenol polyoxyethylene ether, all sodium bicarbonate, and emulsify the appeal mixed material to obtain a pre-emulsion;
[0045] b Stir the above-mentioned pre-emulsion at 83°C for 0.5h to obtain a light blue emulsion;
[0046] c Weigh the remaining 4 / 5 of butyl acrylate and methyl methacrylate, the remaining 1 / 2 of water, the remaining 2 / 3 of potassium persulfate, sodium lauryl sulfate and nonylphenol polyoxyethylene Ether...
