In order to achieve the technical purpose, the technical scheme of the invention is as follows:
the DLP type 3D printing photocuring material with the gradual color change and the effect of imitating anodic oxidation comprises, by mass, 10-30 parts of high-strength aliphatic polyurethane acrylate, 10-30 parts of high-toughness aliphatic polyurethane acrylate, 3-10 parts of a monofunctional radical acrylate monomer, 3-10 parts of a difunctional radical acrylate monomer, 1-5 parts of a pigment, 1-10 parts of 2,4, 6-trimethylbenzoyl-diphenylphosphine oxide, 1-10 parts of interference color aluminum paste, 1-10 parts of chameleon interference type pearl powder, 1-10 parts of UV curable cellulose ester resin, 1-10 parts of non-floating resin coated aluminum paste, 1-10 parts of electroplated silver resin and 1-10 parts of an anti-settling auxiliary agent.
The preparation method of the material comprises the following steps: the raw material components are mixed according to the weight portion ratio, and then stirred for 30-45 minutes at 25-50 ℃ to obtain uniform liquid.
The interference color aluminum silver is a metal pigment taking flaky aluminum flakes as base materials.
Furthermore, the interference color aluminum paste takes the flaky aluminum flakes as a base material, a silicon dioxide layer is coated on the surface of the flaky aluminum flakes for silicon wrapping treatment, and metal particles are plated on the flaky aluminum flakes to form metal pigments. The metal particles are made of metals with different colors, including nickel, tin, zinc and copper.
The non-floating resin coated aluminum silver paste has the metal luster like silk, and is narrower in particle size distribution, whiter and stronger in metal feeling compared with common aluminum silver powder products.
The electrosilvering resin is a special multi-component thixotropic acrylic acid modified polymer, and a unique structure and multiple reaction groups are used, so that interference color aluminum silver paste and non-floating resin coated aluminum silver paste obtain a super-bright mirror effect, the super-silver powder is arranged in a metal sense, and is whitened and brightened by several times, and the whiteness of the silver powder and the metal sense of the pearl powder are effectively improved. Further, the electrosilvering resin is a hydroxyl and ethyl cellulose modified acrylate, its macromolecule has many branch structure, there is certain double bond density, and the cellulose in the resin is the macromolecular structure of structural symmetry, after DLP equipment photocuring, macromolecular structure makes the quick shrink solidification of cured layer, with the help of the quick shrink tension of this kind of structure, make interference color aluminium thick liquid and non-superficial type resin parcel type aluminium thick liquid flare-up, help interference color aluminium thick liquid and non-superficial type resin parcel type aluminium thick liquid directional arrangement, the pressurized tends to parallel arrangement, the brightening, obtain the mirror surface effect of a super glittering. And the hydrogen-oxygen bonding network of the resin and the reticular structure of the cellulose generate a special anchoring effect on the non-floating resin coated aluminum silver paste and the interference color aluminum silver paste on the sheet surface modified by the surface modification and the high-molecular complex, so that the movement and rolling of the aluminum silver paste in the material are restrained, the aluminum silver paste is kept in a uniformly dispersed, closely arranged and parallel arrangement state, and the metal feeling of the anodic oxidation is simulated.
The combination of interference color aluminum paste, non-floating resin coated aluminum paste and electro-silvering resin endows the 3D printing material molded workpiece with a high-texture anodic oxidation effect.
The chameleon interference type pearl powder is prepared by taking artificially synthesized transparent flaky silicon dioxide as a substrate, wrapping a metal oxide with a high reflection effect, and wrapping a layer of transparent color pigment capable of absorbing light with certain wavelength. Different color effects, multiple color effects and color flow are presented along with different angles of the observer. The optical phenomena of two different color senses of the application system containing the pigment when observed in the vertical (front) direction and in the side (side direction) direction are caused by the interference and absorption of the incident light by the pigment, and the silica plate crystal with the producible particle size and narrow thickness distribution is made into multilayer light by the transparent SiO2The metal oxide with high reflection effect is wrapped on the crystal plate, and the material shows very pure and bright magic color effect and color-changing property with angle. The color change effect is caused by light interference, and the color generated by light reflection is different due to different thicknesses of the curing layers. Incident light is reflected/refracted by the cured layer, part of the light (e.g., red) passes through the pigment, and the rest (green in this case) is reflected, and since the interference color contains two colors, the background color should be considered. In the case where the background color is white, the complementary color, which is a transmission element, is reflected by it and then the change effect is reduced in order in combination with the original reflected color. In the case where the background is black, the transmitted complementary color is attracted thereto, and the original reflected color is clearly retained.
The combination of the chameleon interference type pearl powder and the interference aluminum paste endows the 3D printing material forming workpiece with a gradient color effect to a certain degree.
The UV-curable cellulose ester resin can increase the setting arrangement of interference aluminum paste, chameleon interference type pearl powder and non-floating type resin-coated aluminum paste, improve the directional arrangement effect, and improve the compatibility of the interference aluminum paste, the chameleon interference type pearl powder and the non-floating type resin-coated aluminum paste with the main resin.
The pigment is a pigment wetting dispersant, and further, the pigment is a polyether phosphate such as digaTEGO Dispers 655.
The anti-settling assistant is a mixture of polyamide wax and oxidized polyethylene wax, such as Japanese Disibulon anti-settling assistant NS-5501.
