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.
