Problems solved by technology

[0002] After the ink is printed on the printed matter, due to poor wear resistance, the ink will fall off and fall off during the transportation and use of the printed matter. Part of it falls off, which will affect the appearance and quality of the printed matter. If the degree of scratches is reduced by reducing the transfer speed, the production efficiency will be reduced

Abstract

The invention discloses printing ink. The printing ink is prepared from the following materials in parts by weight: 20-40 parts of polyurethane resin, 40-60 parts of solvent, 5-10 parts of polyamide resin, 1-5 parts of organic bentonite, 0-7 parts of conducting component, 3-6 parts of curing agent, 1-3 parts of polymerization inhibitor, 1-3 parts of vegetable oil, 1-5 parts of defoaming agent, 1-3parts of waterproof agent, 1-3 parts of coloring material, 1-3 parts of wetting agent and 5-10 parts of pH stabilizer. The printing ink disclosed by the invention has the advantages that due to addition of the vegetable oil, on one hand, the lubricity and the dispersity of the ink can be improved, on the other hand, proper viscosity can be blended, so that under the action of grease, the ink shows properer yielding property; the organic bentonite is nanoscale particles, so that the combination degree with the ink is higher and the characteristics of the organic bentonite can be more fully exerted; the material used for a triethanolamine buffering agent or a dimethylacetamide buffering agent is used as the pH stabilizer, so that the change of the ink viscosity and the drying speed due to pH-value change in the ink printing process is reduced, and a stable printing effect is obtained.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a printing ink. Background technique [0002] After the ink is printed on the printed matter, due to poor abrasion resistance, the ink will fall off and fall off during the transportation and use of the printed matter. Part of it falls off, which will affect the appearance and quality of the printed matter. If the degree of scratches is reduced by reducing the transfer speed, the production efficiency will be reduced. [0003] The drying speed, thixotropy, and skeleton performance of ink have a huge impact on production efficiency and product quality, and the composition of ink has an impact on the human body. How to study the harm to the human body as little as possible, good wear resistance, high production efficiency, environmental friendliness, Low-cost ink has become the development direction of the printing industry in the future. Contents of the invention [0004] The...
