Problems solved by technology

[0002] Because the surface of the film is very smooth, the adhesion of general digital ink is low, and it cannot be printed on it, and it is difficult to achieve the effect of film washing. However, if the washing method is used, on the one hand, it needs to be processed in a washing shop, and the washing time is longer. It is not conducive to improving work efficiency, but the effect of printing based on general ink is not good

Abstract

The invention discloses printing ink, which is characterized by comprising the following components (by weight): 15%-25% of rosin modified phenolic resin, 10%-15% of polyacrylic resin, 10%-30% of silicon dioxide, 20%-40% of a water-based pigment, 2%-4% of dibutyl ester, 3%-7% of aldehyde ketone resin, 0.1%-2% of triglyceride, 0.1%-1% of polyether acrylate, 0.1%-0.6% of polyvinyl chloride, 0.1%-1%of polyethylene glycol terephthalate, 0.1%-0.7% of polyoxyethylene polyoxypropylene pentaerythritol ether, 0.1%-2% of polyethylene glycol, 1%-2% of alkyl sodium sulfonate, 1-3 of fatty alcohol-polyoxyethylene ether and 15%-25% of distilled water. This printing ink is directly applicable to films. The invention also provides a printing ink preparation method which can reduce the cost and significantly improve the production efficiency.

Description

technical field [0001] The invention relates to an ink that can be directly output on film and a preparation method thereof. Background technique [0002] Because the surface of the film is very smooth, the adhesion of general digital ink is low, and it cannot be printed on it, and it is difficult to achieve the effect of film washing. However, if the washing method is used, on the one hand, it needs to be processed in a washing shop, and the washing time is longer. It is not conducive to improving the efficiency of work, but the effect of printing based on general ink is not good. Contents of the invention [0003] The object of the present invention is to provide an ink that can be directly output on the film. [0004] Another object of the present invention is to provide an ink preparation method that can reduce costs and significantly improve production efficiency. [0005] First purpose of the present invention is achieved like this: [0006] An ink that can be dir...
