Abstract

The invention provides a water-resistant ink-absorbing coating material as well as a preparation method and application thereof. The water-resistant ink-absorbing coating material comprises a combination of an acrylic resin adhesive, an amino silane coupling agent and silicon dioxide, wherein the preparation raw materials of the acrylic resin adhesive comprise a combination of vinyl acetate, n-butyl acrylate, methyl methacrylate, methacrylic acid and an initiator. According to the invention, the acrylic resin adhesive prepared from the preparation raw materials is added as a matrix, and the amino silane coupling agent and the silicon dioxide are added in a matched manner, so that the water-resistant ink-absorbing coating material can be uniformly spread on an aluminum laminated film, has good adhesive force with the aluminum laminated film, and has excellent bonding performance on ink for ink-jet printing. In addition, the surface of the aluminum laminated film can be endowed with certain scratch resistance, wear resistance and brightness.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a water-resistant and ink-absorbing coating material and a preparation method and application thereof. Background technique [0002] In recent years, inkjet printing, as a special printing method with no contact, no pressure, and no printing plate, has been more and more widely used because of its advantages of low cost, short production cycle, and no pollution, involving wood, glass, crystal, etc. , metal plates, floor tiles, tiles, CDs, acrylic, leather, silicone, plastic, cloth, stickers, and stone surfaces are gradually being used in the field of aluminized film printing, packaging and decoration. As a special substrate with metallic luster, aluminized film is dazzling and magnificent, and has an irreplaceable low position in the field of packaging and decoration. It is generally composed of PET substrate, coloring layer and aluminum plating layer. [0003] At p...
