Embodiment 1-12

[0033] According to test material, the photocurable resin of different components is set, and the component composition of each embodiment 1-12 is as shown in table 2.

[0034] The content (mass percentage %) of various compositions in the embodiment 1-12 of table 2

[0035]

[0036]

[0037] The preparation method of the photocurable resin of embodiment 1-12 is as follows:

[0038] (1) Purchasing raw materials, storing and producing them at a temperature of 25°C, humidity below 40%, and dark conditions.

[0039] (2) Check whether the dispersing emulsifier is clean, whether the pipes and valves are in place

[0040] (3) Heat the raw materials in an oven at 60° C. for 30 minutes to reduce the viscosity for later use.

[0041] (4) Add cationic photocuring agent and free radical photocuring agent in proportion to the dispersion emulsifier, set the temperature at 60°C, 50 rpm, and stir for 2 hours.

[0042] (5) Add the free radical photoinitiator and cationic photoinitiat...

Abstract

The invention provides light-cured resin. The light-cured resin comprises the following components in percentage by mass: 40-60% of a cationic light curing agent, 5-15% of a free radical light curing agent, 2-6% of a cationic light initiator, 1-4% of a free radical light initiator, 3-10% of organic silicon modified resin and 6-15% of bisphenol fluorene acrylate. The light-cured resin is high in transparency.

Description

technical field [0001] The invention relates to a photocurable resin and a preparation method thereof, belonging to the technical field of photocurable resin materials. Background technique [0002] Photocurable materials are obtained by photopolymerization. Photopolymerization refers to the addition reaction of photocurable monomers or copolymers under ultraviolet or visible light technology. The free-flowing liquid undergoes chemical reaction by accepting ultraviolet radiation energy A phase transition process that polymerizes and reacts to a non-sticky solid. 3D printing light-curing material is the photopolymerization reaction of photosensitive resin under the irradiation of the laser of the light-curing 3D printing rapid prototyping equipment. [0003] Light-curing 3D printing has high requirements on material properties. It needs to ensure that the printing material flows evenly at a certain temperature, the curing time should be as fast as possible, and it also requi...
