Embodiment 1-3

[0044] According to the formula in Table 1, the special inkjet ink for PVC cables was prepared by the following method: first mix methyl ethyl ketone, propylene glycol methyl ether acetate and N-methylpyrrolidone according to the recipe amount, and then make an organic solvent mixture. Then add the hydroxyl group-containing vinyl acetate resin E22 / 84A (Wacker Chemical, Germany) and acrylic resin BR-106 (Mitsubishi, Japan) into the above part of the organic solvent mixture, stir and dissolve at room temperature (25°C), A binder resin mixed solution was prepared. Secondly, titanium dioxide R-900 (DuPont, USA) was added to the organic solvent mixture of the remaining formulation amount, stirred and dispersed at room temperature (25°C) to obtain a colorant mixture. Finally, mix the above-mentioned adhesive resin mixture and colorant mixture evenly at room temperature, and add the recipe amount of triethyl citrate, Silquest A-1100 (Momentive, USA), Solsperse TM 24000 (Lubrizol, U...

Embodiment 4-6

[0050] According to the formula in Table 3, the special inkjet ink for PVC cables was prepared by the following method: first mix methyl ethyl ketone, propylene glycol methyl ether acetate and N-methylpyrrolidone according to the recipe amount, and then make an organic solvent mixture. Then add the hydroxyl-containing vinyl vinyl resin E22 / 48A and acrylic resin BR-106 into the above-mentioned organic mixed solution of the remaining recipe amount, stir and dissolve at room temperature (25°C) to obtain a binder resin mixed solution . Next, add titanium dioxide R-900 to the mixed solvent of the remaining recipe amount, stir and disperse at room temperature (25°C) to prepare a colorant mixed solution. Finally, mix the above-mentioned adhesive resin mixed solution and colorant mixed solution at room temperature, and add triethyl citrate, Silquest A-1100, Solsperse TM 24000, lithium trifluoromethanesulfonate and fluorine grease FC TM -4430, stirring, grinding with a nanometer hor...

Embodiment 7-9

[0056] According to the formula in Table 5, the special inkjet ink for PVC cables was prepared by the following method: first mix butanone, propylene glycol methyl ether acetate and N-methylpyrrolidone according to the recipe amount to make a mixed solvent. Then add the hydroxyl group-containing vinyl vinyl resin E22 / 48A and acrylic resin BR-106 into the above-mentioned part of the organic solvent mixture, stir and dissolve at room temperature to obtain a binder resin mixture solution. Second, the carbon black Black C-K (BASF-Ciba, Germany) and / or carbon black 400R (Cabot Chemical, USA) and / or solvent-based black dye Add Black RLI (BASF-Ciba, Germany) to the remaining amount of the organic solvent mixture, stir and disperse at room temperature to prepare the colorant mixture. Finally, mix the binder resin mixed solution and the colorant mixed solution evenly, add triethyl citrate, Silquest A-1100, Solsperse TM 24000, lithium trifluoromethanesulfonate and fluorine grease FC ...

Abstract

The invention discloses a special jet ink for PVC (polyvinyl chloride) cables, which consists of the following components by weight portions: 60-90 portions of organic solvent mixture, 5-12 portions of binder resin, 1-10 portions of colorant, 0.1-2.0 portions of plasticizer, 0.1-2.0 portions of adhesion promoter, 0.1-2.0 portions of surfactant, 0.2-5.0 portions of dispersing agent and 0.1-2.0 portions of conductance agent. The special jet ink for PVC cables disclosed by the invention is suitable for PVC substrate printing and has small particle size and good sprayability. The jet ink can quickly dry on the surface of the PVC substrate, having the advantages of stain resistance, scratch resistance, strong adhesion and good printing quality, printing stability, ink dryness and storage stability. The jet ink does not block the nozzle during printing and has good adhesion to PVC cables and good durability.

Description

(1) Technical field [0001] The invention relates to the field of inkjet printing, in particular to a special inkjet ink for PVC cables and a preparation method. (2) Background technology [0002] Inkjet ink is a kind of liquid ink that can be sprayed onto the substrate as required and produce image text after being affected by the electric field between the nozzle of the inkjet printer and the substrate. Coding ink requires not to block the nozzle during the spraying process, and not dry on the nozzle wall, but it can be quickly dried and firmly attached to the substrate when it is sprayed, and has excellent stain resistance and scratch resistance. [0003] There are US6726756, US7520926, US6444019, US6231654, etc. related patents for overcoming the problem of nozzle clogging or oblique spraying, usually the solvent and resin system they adopt are all very expensive. [0004] For PVC cable surface spray printing, since PVC cable material contains a large amount of plasticiz...
