The invention discloses a UV light-cured texture paint for similar 3D printing, its preparation and use, comprising the following raw materials in parts by weight: 20-40 parts of yellow-resistant modified epoxy acrylate, 20-40 parts of urethane acrylate, amino acid 20-30 parts of graphene grafted epoxy acrylate, 1-5 parts of auxiliary agent, 2-10 parts of photoinitiator, 0-20 parts of pigment and filler, 20-40 parts of UV light curing active diluent; The preparation method of the alkene-grafted epoxy acrylate is: 1) preparing aminographene; 2) dispersing the aminographene in a tetrahydrofuran solvent, then adding the epoxy acrylate, stirring evenly, adding a catalyst, and warming up to 50- 60 ℃, add 2-6 parts of ethylenediamine dropwise and keep stirring, after the ring-opening grafting reaction for 3-6 h, the temperature is raised to 85-100 ℃, and stirring is continued for 1-2 h. The invention utilizes UV light-curing texture paint combined with one coating and UV flat-panel printing to perform surface texture treatment, and adjusts the depth of the surface texture by controlling the degree of surface curing, without using a UV-3D printing process. |
