Antibacterial offset printing ink and preparation method thereof

Abstract

The invention relates to the technical field of offset printing ink preparation, in particular to antibacterial offset printing ink and a preparation method thereof. The antibacterial offset printingink is prepared from the following raw materials in parts by weight: 60-80 parts of a binder, 4-6 parts of pigment, 30-40 parts of filler, 30-40 parts of a solvent and 1-3 parts of a bactericide. According to the antibacterial offset printing ink and the preparation method thereof, firstly, nano-TiO2 with the antibacterial function is adopted as the filler, secondly, sulfonamides which have no side effect on human bodies are added into the offset printing ink so as to achieve the antibacterial effect, so that the prepared offset printing ink has the antibacterial property, meanwhile, no harm can be caused to the human bodies while the antibacterial purpose is achieved, and therefore no harm is caused to the environment and human health, the energy-saving and environment-protecting effectscan be facilitated, in addition, the antibacterial function can be achieved, and the popularization and application prospect is good.

Description

Technical field: [0001] The invention relates to the technical field of offset printing ink preparation, in particular to an antibacterial offset printing ink and a preparation method thereof. Background technique: [0002] Offset printing ink is mainly a fluid coloring material composed of pigments, additives, polymers and solvents. Among them, the main solvents of offset printing ink are mineral oil and vegetable oil. The drying process of offset printing ink on paper is very complicated. We can understand that the ink is dried through the penetration of mineral oil and the oxidized conjunctiva of vegetable oil. As the most important printing material for information reproduction, ink should have good printability during printing. Offset printing ink is mainly composed of colored pigments, binders, fillers and additives. When preparing, it is mixed and stirred according to the printing requirements according to a certain proportion, and it is made by rolling and rolling. ...

AI Technical Summary

Problems solved by technology

The offset printing inks currently on the market do not have antibacterial properties, and the products printed with these offset printing inks do not have antibacterial properties, and the surface is easily contaminated with bacteria, which is difficult to meet people's needs. The application number is CN201410362497.1. Printing inks with antibacterial Chinese medicine ingredients, adding zinc oxide, Daqingye, and Coptis chinensis to the components for antibacterial, using the bactericidal properties of rhubarb leaves and Coptis chinensis for antibacterial, its antibacterial performance is single, and the effect is not significant. The application number is CN1195120C relates to antibacterial ink, adopts inorganic silver-loaded antibacterial agent

When a single metal ion-loaded inorganic antibacterial agent is added to the ink, the antibacterial effect is not significant, or the product changes color. For example, the antibacterial effect of the sample obtained by adding silver ion-loaded zeolite or silicon oxide antibacterial agent to the ink is reproducible. Bad or insignificant, and the wear of equipment such as three-roll machines is serious during the ink production process, so it is not suitable for ink production
