Problems solved by technology

The adhesion of this ink on the surface of polyethylene and polypropylene materials is quite small, the adhesion fastness is very poor, and the organic solvent is used in the formulation, which has negative effects on human health and the environment
The Chinese invention patent application with the application number 03116083.2 discloses a coding ink formula using acrylic resin as the binder, which also has the defect of poor adhesion fastness on the surface of PE materials, and the ink solvents are all non-environmentally friendly organic materials. solvent
[0003] An effective way to reduce the volatile organic compounds of the ink is to make the ink water-based. However, there is currently no water-based inkjet ink that can obtain better adhesion on the surface of PE materials.

Abstract

The invention discloses a high-performance emulsion type water-based code-spraying printing ink for polyethylene, which is prepared from the following components in parts by weight: 5-10 parts of modified polyethylene resin, 10-40 parts of butanone, 1-5 parts of a water-soluble dye, 0.5-2 parts of a conductivity improver, 0.5-2.5 parts of a plasticizer, 0.5-5 parts of an emulsifying agent, and 40-90 parts of water. According to the invention, through selecting an appropriate connecting material and an additive matched with the connecting material, the adhesion property of the code-spraying printing ink on a PE material in the process of spray printing is better, the system performance is stable, and prints are clear; and in addition, the utilization of organic solvents is completely abandoned in an code-spraying printing ink formulation disclosed by the invention, thereby greatly reducing the harm of the code-spraying printing ink to the human body and the environment in the processes of preparation and utilization.

Description

technical field [0001] The invention relates to a high-performance emulsion-type water-based inkjet ink for polyethylene, in particular to an inkjet ink with water as a solvent, which has excellent adhesion when applied on the surface of polyethylene materials. Background technique [0002] As human society pays more and more attention to the safety issues of food, medicine and cosmetics, many countries clearly require that the labels or other packaging of food, medicine and cosmetics must be printed with information such as production date, batch number and shelf life, so that the spray Code inks are widely used. According to relevant market analysis and statistics, in the film products used for packaging food, medicine and cosmetics at home and abroad, the proportion of polyethylene materials has reached as high as 1 / 4, and the usage rate is increasing year by year. However, most of the inkjet inks currently on the market are only suitable for printing on the surface of s...
