(2) preparation of oil phase：First GMA and hydroxyethyl methacrylate are heated into 85-90 DEG C of insulation
Mixing 5-10min, adds divinylbenzene, pore-foaming agent and initiator, is sufficiently mixed after microwave frequency 2450MHz, power
Microwave treatment 3-5min under 700W, stands and continue after 15-30min microwave treatment 3-5min, obtains final product oil mixture；
(3) suspension polymerization：Vanillyl alcohol butyl ether is added in aqueous phase solution, reflux state isothermal holding 10- is heated to
15min, adds oil mixture, continues isothermal holding 3-5h at reflux, then add while hot HPMA and
Cumarin, insulation mixing 15-20min, gained mixture is cooled under ice salt bath with the speed of 10-15 DEG C/min, is treated
Insulation after temperature is down to 0-5 DEG C stands 1-2h, filters, and gained filter cake is washed 3 times with 60-65 DEG C of 2-3wt% sodium chloride solutions,
And 3-5h is dried at 100-105 DEG C, finally with the screen filtration in 0.5mm apertures, obtain final product transparent spherical resin；
(4) functionalization：Polyglycerol polyricinoleate is added in ethanol, reflux state insulation mixing 10-15min is heated to,
Then 45-50 DEG C is naturally cooled to, resulting solution is uniformly sprayed on transparent spherical resin surface, to be stood and add silicon after 15-30min
Sour magnalium and microcrystalline cellulose, are sufficiently mixed, microwave treatment 3-5min under microwave frequency 2450MHz, power 700W, process
Proceed to rapidly after end and 2-3h is stood in 0-5 DEG C of environment, again microwave treatment 2-3min, finally by gained particle in 75-80 DEG C
Under be dried 2-3h, obtain final product target resin.
