[0019] Example 2: Add 10 parts of zinc oxide, 0.1 part of titanate coupling agent, and 90 parts of hexanol to a reactor equipped with a thermometer, agitator and reflux condenser, heat up to 65°C, rotate at 300 rpm, and stir for 2 Hour, discharge, obtain pre-treated zinc oxide; pre-mix 5 parts of pre-treated zinc oxide, 0.1 part of sorbitan trioleate, 1 part of sodium lauryl sulfonate, and 80 parts of deionized water Ultrasonic dispersion for 2min, power 250w, quickly transfer the mixture into a reactor with a stirrer and reflux condenser, heat up to 55℃, rotate at 200rpm, and then add 0.15 part of potassium persulfate and butyl methacrylate 2 Part and 0.9 part of methyl methacrylate are mixed and slowly added dropwise to the reaction kettle, continue to heat up to 70°C, rotate speed 200rpm, react for 3 hours, cool and discharge, naturally precipitate overnight, remove the lower layer of precipitation and repeatedly wash with water and filter with suction After drying, it is repea...
Example Embodiment
[0020] Example 3: Add 10 parts of zinc sulfide, 0.1 part of aluminate coupling agent, and 90 parts of hexanol to a reactor equipped with a thermometer, agitator and reflux condenser, heat up to 65°C, rotate at 300 rpm, and stir for 2 Discharge the pre-treated zinc sulfide after hours, discharging, and obtain pre-treated zinc sulfide; pre-mix 5 parts of pre-treated zinc sulfide, 1.1 parts of ethylene glycol fatty acid grease, and 80 parts of deionized water, and then ultrasonically disperse for 2 minutes. Put it into a reactor with a stirrer and a reflux condenser, heat up to 55°C, rotate at 200 rpm, then add 0.15 part of ammonium persulfate, 2 parts of methyl methacrylate and 0.9 part of styrene, and then slowly add dropwise to the reaction. In the kettle, continue to heat up to 70°C, rotate at 200rpm, react for 3 hours, cool and discharge, naturally precipitate overnight, remove the lower layer of precipitation and repeatedly wash with water, suction and filter, dry, and then rep...
