Embodiment 1
[0037] Embodiment 1 A preparation method of bowl-shaped polymer microspheres, comprising the following steps:
[0038] (1) Add the initiator azobisisobutyronitrile into the methacrylate mixed monomer mixture, and dissolve it by ultrasonic cleaning for 1 min to obtain the methacrylate mixed monomer-initiator mixed liquid; then, under sufficient stirring conditions The methacrylate mixed monomer-initiator mixture was added to the alcohol aqueous solution at a temperature of 70 °C, and kept stirring at 70 °C for 3 h to obtain a methacrylate polymer solution.
[0039] Wherein: the methacrylate mixed monomer mixture includes three monomers: 1.0 g methacrylic acid, 3.0 g methyl methacrylate, and 2.0 g butyl methacrylate.
[0040] The addition amount of initiator is 0.5% of the mass of methacrylate mixed monomer mixture;
[0041] The volume ratio of the methacrylate mixed monomer-initiator mixture to the alcohol aqueous solution is 1 mL:7 mL.
