Embodiment 1
[0020] (1) Take 55g of industrial divinylbenzene, 40g of methyl acrylate, 5g of GMA, and 1g of benzoyl peroxide and mix them evenly, add 55g of toluene and 55g of liquid paraffin, and mix the above-mentioned substances evenly at room temperature to obtain an oil phase.
[0021] (2) Add 55g of 0.2% polyvinyl alcohol and 137g of 0.5% gelatin to 547g of 2.5% sodium chloride aqueous solution as the water phase, and heat to 50°C in a water bath.
[0022] (3) Add the oil phase to the water phase, start the agitator, control the stirring speed, disperse the oil phase and control the particle size of the oil beads at 60 mesh, raise the temperature to 69°C at a constant speed for 1 hour and keep it for 2 hours to shape, and then use Heat at a constant speed of 1 hour to 78°C for 4 hours, then heat at a constant speed of 0.75 hours to 85°C for 2 hours, and finally heat at a constant speed of 0.5 hours to 91°C for 12 hours to complete the polymerization and obtain a crude resin product. ...
