Surface multi-resistance decorative paper intaglio printing process and equipment

Abstract

The invention relates to the technical field of intaglio printing, and particularly discloses a surface multi-resistance decorative paper intaglio printing process and equipment. The surface multi-resistance decorative paper intaglio printing process comprises the following steps that silica gel liquid synthesis is conducted, specifically, olefin silicone oil, silica gel oil, a cross-linking agent, a catalyst and a curing agent in a proper proportion are taken and put into a feeding bin, and the silica gel liquid is prepared after stirring and mixing; silica gel liquid pasting: taking a decorative paper base material, and coating the silica gel liquid on the back surface of the decorative paper base material to form a silica gel film; pattern printing, wherein patterns are printed on the decorative paper base material covered with the silica gel film through an ink printing unit; coating a protective layer, namely coating the decorative paper base material printed with the pattern with the protective layer by a protective layer roller coating unit; the wear resistance, the pollution resistance, the solvent resistance, the antibacterial property and the like of the decorative paper finished product are improved; and removing the silica gel film, and after the protective layer is dried, tearing off the silica gel film on the back surface of the decorative paper base material to obtain a decorative paper finished product. The invention has the characteristics of small deformation error, low production cost and multi-resistance performance.

Description

technical field [0001] The invention relates to the technical field of gravure printing, in particular to a gravure printing process and equipment for surface multi-resistant decorative paper. Background technique [0002] In the gravure printing work of decorative paper, it is necessary to apply extension force to the base layer of the decorative paper to prevent wrinkles. In the pattern printing work, the ink printing unit used is WAD-800B gravure printing machine. The roller body needs to apply the extrusion force of transferring ink to the substrate layer, and after finishing the pattern printing work on the substrate layer of the decorative paper, it is necessary to use the QG-1300# model roller coater to perform various coatings on the substrate layer. Protective layer coating work, and use TY-UV1000 dryer for drying treatment, in order to improve the wear resistance, pollution resistance, solvent resistance and antibacterial performance of decorative paper, but for so...
