High-grade chipping-resistant water-based ink and preparation method thereof

Abstract

The invention discloses high-grade chipping-resistant water-based ink and a preparation method thereof. The high-grade chipping-resistant water-based ink is prepared from mineral oil, pigments, and the like, wherein cellulose resin is lac resin, hydroxypropyl cellulose, hydroxypropyl methyl cellulose, carboxymethyl cellulose, methyl cellulose, microcrystalline cellulose, gelatin, casein, and the like; a conductive agent is sodium lactate, sodium acetate or sodium pantothenate; the high-grade chipping-resistant water-based ink is prepared from 1-30 parts of charcoal powder, 1-30 parts of lac resin, 0.1-20 parts of cellulose resin, 40-90 parts of more than 60% (v / v) ethanol, 3-20 parts of water and 0.1-2 parts of conductive agent by weight. The water-based ink and the preparation method have the beneficial effects that by adopting the preparation method comprising the steps of weighing the materials according to weight and parts by weight, preparing a first solvent, preparing a dispersion, preparing a lac solution and preparing the high-grade chipping-resistant water-based ink after mixture, the prepared water-based ink does not easily undergo chipping, is convenient to use, has good safety performance, is low in maintenance cost and has longer service life.

Description

technical field [0001] The invention belongs to the technical field of ink materials, and in particular relates to a high-grade chipping-resistant water-based ink and a preparation method thereof. Background technique [0002] At present, water-based ink water-based ink water-based ink is referred to as ink for short, and flexographic water-based ink is also called liquid ink. It is mainly made of water-soluble resin, organic pigment, solvent and related additives through compound grinding. Water-based ink is especially suitable for packaging and printing products that require strict hygienic conditions such as tobacco, alcohol, food, beverages, medicines, and children's toys. Water-based ink is a uniform paste-like substance composed of binders, pigments, additives and other substances. The binder provides the necessary transfer performance of the ink, and the pigment gives the ink its color. The binder of water-based ink is mainly divided into two types: water-diluted an...
