Embodiment 1

[0039] The method for synthesizing GMA acrylic resin in this embodiment comprises the following steps:

[0040] (1) Add the first solvent toluene, monomer and composite initiator into the pre-mixing tank, mix them uniformly initially, and obtain the reaction raw materials; wherein the monomer adopts methyl methacrylate, styrene, ethyl acrylate, butyl acrylate four The first monomer is compounded at 2:2:1:1, and the composite initiator is compounded with azobisisobutyronitrile and benzoyl peroxide at a ratio of 3:2. The amount of the first solvent toluene is the monomer and compound 25% of the total amount of initiators; among them, composite initiators accounted for 3%, 4% and 5% of the total mass of monomers, making three groups;

[0041] (2) Microchannel reactor is put into constant temperature reaction tank, and microchannel reactor is connected with two feed pumps; Wherein the temperature of constant temperature reaction tank is set to 105 ℃;

[0042] (3) By a feed pump, ...
