Problems solved by technology

Among them, inorganic antibacterial agents are mainly composed of metal ions and inorganic carriers, including antibacterial agents containing metal ions, TiO 2 Antibacterial agents, metal oxide antibacterial agents, and antibacterial agents with far-infrared radiation functions (such as CN106221369, 2016-12-14); however, there are some problems in the application of inorganic antibacterial agents in inks, such as antibacterial materials and ink components ( Binders, pigments, etc.) have poor compatibility and are unevenly dispersed in the ink system, thus affecting ink performance
Organic antibacterial agents include chemical organic antibacterial agents and natural organic antibacterial agents, chemical organic antibacterial agents such as n-butyl-phenylpropylisothiazoline-trione (CN108410261, 2018-08-17), natural organic antibacterial agents such as cinnamon essential oil, castor oil, Tea tree oil, chitosan, etc. (screen printing, 2017, (7): 21-24 ); however, most organic antibacterial agents are insoluble in water, have poor compatibility with water-based inks, and are sensitive to light and heat. In general, it is made into microcapsules first, and then added to the ink system, the process is complicated and the cost is high

Abstract

The invention discloses a water-based ink with antibacterial properties and a preparation method thereof. The water-based ink is prepared from the following components in parts by weight: 20~30 partsof water-based acrylic resin, 6~10 parts of pigment, 15~20 parts offilling, 3~5 parts ofan additive, 3~5 parts ofan antibacterial agentand 35~45 parts ofa solvent. The solvent is prepared fromethyl alcohol,propanediol, ammonium hydroxide, ethanolamine and deionized water. Theweight ratio of the ethyl alcohol to the propanediol to the ammonium hydroxide to the ethanolamine tothe deionized waterare4~6:0.5~1.5:1~3:0.5~1.5:30~35, and the mass concentration of the ammonium hydroxide is 23%~28%.The water-based antibacterial ink mainly uses water as solvents,volatilization of organic volatiles can be effectively reduced,green environmental protection can be realized, and the ink obtained has a good dispersing, adhesion and antibacterial properties.

Description

technical field [0001] The invention relates to a water-based ink with antibacterial properties and a preparation method thereof. Background technique [0002] Ink is an important substance used to form graphic information in the printing process. It is usually formed by mixing colored bodies (such as pigments, dyes), linking materials, fillers, additional materials and other materials through a certain process and has certain fluidity and adhesion properties. homogeneous mixture. Ink is used everywhere in life. For example, books, various packaging, banknotes, advertisements and other printed materials need to generate graphic information through ink printing. Traditional inks have been criticized for their harmful solvents, large VOC emissions, and heavy environmental pollution. With the enhancement of people's awareness of environmental protection, water-based inks have gradually replaced traditional oil-based inks, but water-based inks and their printed materials are mo...
