preparation example Construction
[0033]In the specific embodiment of the present application, there is provided a method for preparing a new type of photosensitive resin material for SLA3D printers, including the following mass fraction: prepolymer: 50-70, active diluent 30-50, cationic initiator 1-5, free Base initiator 1-5, catalyst 1-3, modifier 1-10.
[0034]The epoxyacrylate is added to the 2000 ml of the four-port glass flask equipped with a reflow condenser, a stirrer, and a controlled device, and a solvent is added thereto, and a high temperature modifier, a catalyst, and a temperature remaining. At 60 ° C to 90 ° C, the reaction time was stirred for 3-7 hours, the reactant acid value was measured during the reaction. When it tended to be stabilized, the yellow viscous liquid, the discharilized distillation was obtained, and the modified prepolymer was obtained. Active diluent, cationic initiator, free radical initiator, mixed stirring 20-50 min, stopping the reaction to obtain a novel photosensitive resin.
