Embodiment 1

[0038] In the method of preparing digital jet printing UV lacquer ink by grinding and dispersing in this embodiment, the mass percentages of each component are as follows:

[0039]

[0040] According to the above mass ratio formula, epoxy modified raw lacquer is ground and added to UV ink, ultrasonically dispersed for 30 minutes, and filtered to obtain digital jet printing UV raw lacquer ink by grinding and dispersing.

Embodiment 2-5

[0042]In the method of preparing digital jet printing UV lacquer ink by grinding and dispersing in this embodiment, the mass percentages of each component are as follows:

[0043]

[0044] According to the above mass ratio formula, add epoxy modified raw lacquer and appropriate amount of UV ink, wetting and dispersing agent, and defoaming agent to the container and stir evenly. Then put it in a grinder, grind for 5-24 hours, then put the ground liquid into a beaker after coarse filtration, add an appropriate amount of UV ink, stir and ultrasonically disperse for 15-30 minutes. Then add an appropriate amount of diluent and additives to prepare the solution to the desired performance index, and use a microporous membrane to filter out the larger particles after coarse filtration. Finally, add an appropriate amount of additives or diluents, stir, and ultrasonically disperse for 15-30 minutes to obtain a digital jet printing UV lacquer ink.

Embodiment 6

[0046] In the method of preparing digital jet printing UV lacquer ink by grinding and dispersing in this embodiment, the mass percentages of each component are as follows:

[0047]

[0048] According to the above mass ratio formula, add epoxy modified raw lacquer and appropriate amount of UV ink, wetting and dispersing agent, and defoaming agent to the container and stir evenly. Then put it in a grinder, grind for 5-24 hours, then put the ground liquid into a beaker after coarse filtration, add an appropriate amount of UV ink, stir and ultrasonically disperse for 15-30 minutes. Then add an appropriate amount of diluent and additives to prepare the solution to the desired performance index, and use a microporous membrane to filter out the larger particles after coarse filtration.

Abstract

The invention relates to a digital jet printing UV raw lacquer ink prepared by grinding and dispersion and a preparation method thereof. The invention is characterized in that the digital jet printing UV raw lacquer ink is prepared from the following raw materials in percentage by mass: 45-95% of UV-LED (light-emitting diode) ink, 5-40% of modified raw lacquer, 0-60% of diluter, 0-5% of wetting and dispersing agent and 0-5% of other assistants. The preparation method comprises the following steps: 1) taking raw materials; 2) grinding; 3) carrying out coarse filtration; 4) preparing a raw lacquer ink coarse material; 5) carrying out coarse filtration and microporous filter membrane filtration; and 6) preparing the raw lacquer ink for digital jet printing and UV curing. The raw lacquer ink can be directly printed onto the substrate surface by a digital jet printing apparatus, thereby implementing mechanical operation. The raw lacquer ink has the advantages of simple synthesis technique, controllable conditions and excellent paint film properties, can be widely used in the fields of decoration, furniture, construction, electronics, machinery, chemical industry and the like, and implements conversion of the paint colored drawing from single traditional artificial manufacturing to traditional technique-digitalization combined production.

Description

technical field [0001] The present invention relates to a digital inkjet printing UV lacquer ink and its preparation method by grinding and dispersing, which belongs to the integrated innovation in multiple fields such as digital inkjet printing, UV curing technology, and lacquer. Due to the small-aperture spraying defects of digital inkjet printing equipment, through the treatment of modified raw lacquer, the lacquer art painting has changed from simple traditional manual production to traditional technology and digital technology. [0002] Combining digitization with production transformation. Background technique [0003] The chemical components of raw lacquer (taking Chinese raw lacquer as an example) are mainly urushiol (60%-70%), urushiol (5%-7%), laccase (<1.0%) and water (20%-30%). Raw lacquer film has excellent properties such as outstanding durability, high decorativeness, antibacterial property, oxidation stability, corrosion resistance and environmental frien...
