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 which is prepared from the following raw materials in parts by weight: 20-40 parts of polyamide resin, 40-60 parts of a solvent, 5-10 parts of pigment, 1-5 parts of a viscosity conditioning agent, 0-1.5 parts of vinyl chloride-vinyl acetate resin, 1-3 parts of a printing ink reinforcing agent, 1-5 parts of a wear-resisting auxiliary, 1-3 parts of active monomer, 1-3 parts of hollow glass bead, 1-3 parts of an antifoaming agent and 5-10 parts of a diluent. According to the printing ink, the active monomer is added, so that the surface tension of the prepared printing ink is equal to or less than that of the printed surface; the wear-resisting auxiliary is added, so that the printed printing ink layer has a very small frictional coefficient, and the wear resistance of the printing ink is greatly improved; the printing ink contains no volatile toxic solvent, is good in printing effect, strong in adhesion fastness, incombustible, unexplosive and nontoxic, cannot damage health of printing workers, has no environmental pollution on atmosphere, and is lower in cost; an ink layer is high in adhesion fastness, namely adhesive force, rub-resistant, scratch-resistant, high in glossiness, good in wear resistance, quick in drying rate and good in product quality.

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...
