Abstract

The invention discloses a copperplate surface printing ink and a preparation method of the surface printing ink. The surface printing ink comprises the following materials: solvent 39 to 62.5, resin 23 to 33.5, additive 2 to 4.5, paint powder 7 to 30, in weight portions. Compared with the prior art, the bonding material of the copperplate surface printing ink contains keto-aldehyde resin (XK) and keto-aldehyde resin (CB), so that the flexibility and adhesion of the product are improved; the freeze resistance and water resistance of the production are enhanced, and the production has high viscosity and fine fluidity.

Description

technical field [0001] The invention relates to the field of flexographic printing inks, in particular to a copper plate surface printing ink and a preparation method thereof. Background technique [0002] Printing ink is a paste-like colloid formed by uniform dispersion and mixing of pigments, binders, additives and other components. The pigments make the printed matter have ever-changing colors; the binder is used as a color carrier and also as a binder to fix the pigment on the surface of the substrate. Above; the additives endow the ink with proper properties, so that the ink can meet the printability of various printing processes, the ink should have a certain fluidity, and meet the properties of various printing requirements; it can be dried quickly on the printed matter; after drying The ink should have corresponding water resistance, acid resistance, alkali resistance, light resistance, abrasion resistance, abrasion resistance and other resistance. The liquid compon...
