[0029] Example 1:
[0030] Add 16 parts of methyl methacrylate, 16 parts of butyl acrylate, and 13 parts of 2-trifluoromethyl methacrylate to a drying reactor equipped with a stirring device, a thermometer and a condenser, and then add 32 parts of N, N- Dimethylformamide, 10 parts of α-pinene, 14 parts of D-limonene, 0.7 parts of tert-amyl peroxybenzoate, under the protection of nitrogen, continue to stir at 150rpm, reflux and condense and heat to 90℃, wait 1h Then cool to 55°C, adjust the pH to alkaline with sodium bicarbonate; add 135 parts of water, and perform ultrasonic dispersion for 15 minutes to emulsify; continue to add 24 parts of stearyl acrylate, 1 part of rhamnolipid, 1.5 Part of sucrose fatty acid ester, after reacting at 55°C for 1h, slowly add 18 parts of potassium persulfate 2% aqueous solution and quickly increase the temperature to 85~95°C, after dropping for 2~3h, the reaction is over, cool to room temperature to get acrylic acid Ester polymer emulsion;
