Problems solved by technology

[0004] There are some drawbacks in the existing color adhesive ink materials for 3D printers in China. They are corrosive, slow in bonding speed, and not strong enough to meet the requirements of 3D printers, that is, fluidity, bonding strength, Adhesion time, color, transparency, corrosion and safety cannot meet the requirements at the same time
The existing 3D printer color adhesive ink materials are only suitable for the above-mentioned 650-850 models, and the scope of application is small

Abstract

The invention relates to a colored adhesive ink for 3D printers, which is composed of the following components in parts by weight: 8-10 parts of glycerol, 10-12 parts of ethylene glycol, 0.4-0.6 part of ethylenediamine, 0.6-1 part of monoethanol, 70-88 parts of distilled water, 1-2 parts of activator, 0.5-1 part of dye and 0.1-0.2 part of vinyl acetate. The preparation method comprises the following steps: proportionally weighing the components, mixing the components in a mixing barrel, stirring at the speed of 110-120 r/min under vacuum conditions for 40-50 minutes while controlling the temperature at 30-40 DEG C, filtering the uniform mixed solution with a paper filter, and storing in a sealed state in a dark place. The colored adhesive ink for 3D printers has the characteristics of simple preparation technique, high adhesive strength, high adhesion speed and low corrosivity, and can satisfy the requirements of flowability, adhesive strength, adhesion time, color, transparency, corrosivity, safety and the like for the 3D printers.

Description

technical field [0001] The invention relates to 3D printer consumables, in particular to a color adhesive ink for a 3D printer and a preparation method thereof. Background technique [0002] 3D printer, a machine of rapid prototyping manufacturing technology, is a technology based on digital model files, using bondable materials such as powdered metal or plastic, to construct objects by layer-by-layer printing. The printing process of each layer of 3D printing technology is divided into two steps. First, a layer of special glue is sprayed on the area that needs to be formed. The glue droplet itself is very small and not easy to spread; It will quickly solidify and bond, and the area without glue will remain loose. In this way, the solid model will be "printed" under the alternation of a layer of glue and a layer of powder. After printing, just sweep away the loose powder to "plan" out of the model, and the remaining powder can be recycled. The printing materials used by 3D...
