Abstract

The invention discloses a scratching-resistant aqueous ink which is prepared from the following raw materials in parts by weight: 30-40 parts of modified polyurethane, 35-50 parts of a modified acrylic resin liquid, 5-10 parts of a pigment, 15-20 parts of titanium dioxide, 5-8 parts of a thickening agent, 10-15 parts of a dispersant, 3-8 parts of benzoin ethyl ether and 35-55 parts of absolute ethyl alcohol. The invention further discloses a preparation method of the scratching-resistant aqueous ink. The modified polyurethane and the modified acrylic resin liquid are used in the preparation process of the scratching-resistant aqueous ink, the modified polyurethane disclosed by the invention has good stability, acid-base resistance and wearing resistance, and the finally prepared scratching-resistant aqueous ink has excellent stability and scratching resistance; due to adoption of the modified acrylic resin liquid, the ink has good adhesion solidness and compounding fastness; in addition, the scratching-resistant aqueous ink disclosed by the invention is high in glossiness, attractive in appearance and applicable to multiple fields.

Description

technical field [0001] The invention belongs to the technical field of ink production, in particular to a scratch-resistant ink and a preparation method thereof. Background technique [0002] Ink is an important material for printing. It can express patterns and characters on paper and other substrates through printing. The ink has a certain fluidity and meets the properties required by various printing processes. It can be dried quickly on the printed matter. The dried ink film generally has corresponding water resistance, acid resistance, alkali resistance, light resistance, abrasion resistance, wear resistance, etc. Various resistances. [0003] The existing ink contains various main components and auxiliary components, such as pigments, additives, photoinitiators, etc., wherein various components are uniformly mixed and rolled repeatedly to form a viscous colloidal fluid. The ink itself is usually not scratch-resistant or wear-resistant due to its material, and it is v...
