[0017] First, collect the dolomite clay and place it in a ball mill, mill it at 250r / min for 3h, then pass through a 120-mesh sieve to collect the ball milled powder. According to the mass ratio of 1:10, stir and mix the ball milled powder and deionized water at 200W. Vibrate ultrasonically for 10 minutes to collect the dolomite clay dispersion; then, in parts by weight, weigh 10 parts styrene, 15 parts divinylbenzene, 25 parts polylactic acid monomer, 2 parts acrylonitrile and 10 parts prepared above. Dolomite clay dispersion liquid, stir and mix and heat to 60℃, magnetically stir for 2h; after the stirring is completed, heat and raise the temperature to the boiling of the solution, then keep it for 45min, let stand and cool to 20℃, filter and collect the filter cake, respectively Washed with absolute ethanol and deionized water for 3 times, dried at 65°C for 6 hours to prepare clay modified microspheres; then, in parts by weight, weigh 10 parts of the above-prepared clay modif...
