Embodiment 1

[0033] According to the formulation amount in Table 1, first mix 70 parts of butanone and 6.7 parts of butyl acetate (a low-volatile solvent) to prepare an organic solvent mixture. Then add 3.4 parts of vinyl acetate resin VAGA (acid value 7-10, molecular weight 29000), 3.2 parts of cellulose acetate butyrate CAB-551-0.01 (molecular weight 16000), 3.4 parts of vinyl acetate resin VYHH (molecular weight 27000) to the above organic In the solvent mixture, stir and dissolve at room temperature (25°C) to obtain a mixed resin solution. Next, add 2 parts of dispersant EFKA-6220 and 0.1 part of leveling agent TEGO450 to the mixed resin solution, stir and dissolve at room temperature (25°C), then add 10 parts of titanium dioxide R-930, stir and disperse at room temperature (25°C) Add a sand mill (SGM-15M sand mill of Sanyin Industrial Co., Ltd.) to grind, filter, add 1.2 parts of tetrabutylammonium chloride to the filtrate, and stir evenly to obtain the special inkjet ink for PVC cabl...

Abstract

The invention discloses a special ink-jet printing ink for a PVC (polyvinyl chloride) cable and a preparation method. Every 100 parts of ink-jet printing ink consists of the following raw materials in parts by mass: 60-90 parts of organic solvent mixed liquid, 2-15 parts of coloring agent, 0.1-6 parts of pigment wetting dispersion resin, 1-6 parts of viscosity adjusting resin, 0.1-6 parts of anti-alcohol resin, 0.5-1.5 parts of conductive agent and 0.05-5 parts of auxiliary. The ink-jet printing ink disclosed by the invention has multiple good characteristics of no nozzle blockage, rare ink accumulation at a spray head, easiness in cleaning, good stability, high adhesion, plasticizer resistance, alcohol resistance and the like.

Description

(1) Technical field [0001] The invention relates to a coding ink, in particular to a high adhesion, alcohol-resistant and easy-to-clean special inkjet ink for PVC cables. (2) Background technology [0002] Continuous inkjet printing is a printing technology in which charged ink droplets are deflected differently through a high-voltage electric field to form images on the surface of the substrate as required. The inkjet printer is the equipment that uses this printing technology to print the production date, batch number, shelf life and other marks on the substrate. The ink used in the inkjet printer is required not to block the nozzle during the spraying process, and not dry on the wall of the nozzle, but it can be quickly dried and firmly attached to the substrate when it is sprayed, and has excellent resistance to staining, scratching and wiping . [0003] For cables with PVC as the main material, in addition to the above requirements, the inkjet ink is also required to ...
