A kind of water-based nanometer four-color ink

Abstract

The invention discloses a waterborne nano four-color printing ink. The waterborne nano four-color printing ink comprises the following components: waterborne nano polyurethane, an auxiliary agent, water, toner, waterborne slowly drying paste, a bridging agent and the like, wherein the waterborne nano polyurethane is polycarbon type waterborne polyurethane, and the waterborne slowly drying paste is betaine modified polyethylene glycol. The waterborne printing ink has the advantages of good stability, excellent color strength, glossiness and transparency, fine particle size, high coloring rate, good color-setting property, non-diffusion of screen dots, non-blocking of a printing plate, clear images and the like, and especially patterns printed by the waterborne printing ink are washable, wear-resistant, and resistant to bending for more than 100000 times.

Description

technical field [0001] The invention relates to a water-based nano four-color ink, in particular to a water-based four-color ink suitable for screen printing, in particular to a water-based four-color nano ink for fabrics and shoe materials, and belongs to the technical field of water-based inks. Background technique [0002] With the improvement of people's living standards, people's awareness of environmental protection is also increasing, and more and more people have begun to pay attention to the living environment of human beings themselves. Therefore, while pursuing fashion, people have also begun to pay attention to the choice of environmentally friendly coatings. Traditional solvent-based inks contain a large amount of organic solvents, which will emit a large amount of VOC during production and construction, directly endangering human health and causing environmental pollution. According to relevant statistics, the global VOC emissions to the atmosphere are as high ...

Problems solved by technology

Chinese patent (CN102532994A) discloses a water-based ink suitable for flexographic printing and gravure printing, consisting of pigments, binders, dispersants and auxiliary agents, the binder is a polyolefin emulsion, due to the use of polyolefin ( Polyvinyl and polypropylene-based) emulsions are used as adhesives for water-based inks, because their film-forming temperature is higher than that of acrylic polymers, and the natural molecular structure of polyolefins, so it has three anti-water and oil resistance properties, transparency and The reflectivity is much higher than that of acrylic polymers, so it shows a very high comprehensive performance in printing, but it still needs to use a large amount of organic solvents as co-solvents, and does not really eliminate VOC emissions

[0005] Shoe materials and fabrics are necessities in daily life. The surface of shoe materials and fabrics is often designed with beautiful patterns. These patterns can be woven by textile technology. The patterns obtained through weaving are wear-resistant and do not fall off. However, the weaving process is complicated and costly, which is not conducive to Industrial production

Printing patterns with printing technology is convenient and quick, and the cost is greatly reduced. However, the existing inks for fabrics and shoe materials are generally oily inks, which have a strong brush odor, a large amount of VOC emissions, slow drying, poor resistance to twists and turns, and caused by plate plugging. The image is not clear, etc.
