Abstract

The invention discloses an aqueous environment-friendly paper product laminating-imitation coating preparation and a preparation technique thereof. The coating preparation comprises the components by weight percent: base material A, base material B, wax emulsion and deionized water, wherein the base material A accounts for 20-60% of the system and comprises acrylic ester polymer solution with concentration (W / W) of 20-60%; the base material B accounts for 10-60% of the system and comprises one or combination of more in aqueous butadiene-styrene rubber emulsion with concentration (W / W) of 20-60%, aqueous polyester resin, aqueous polyurethane resin and aqueous alkyd resin; the wax emulsion accounts for 2-10% of the system; and the deionized water accounts for 3-20% of the system. The aqueous environment-friendly paper product laminating-imitation coating preparation can be directly coated on the surface a paper printing product and forms a protecting coating, thus replacing the traditional oil or water laminating, and ensuring the coated printing product to meet the need of the laminating and the demand of environmental protection and safety performance.

Description

technical field [0001] The invention belongs to the technical field of imitation lamination coating preparations, and in particular relates to a high-performance imitation lamination coating preparation modified on the basis of acrylate polymers and a preparation method of the imitation lamination coating preparation. Background technique [0002] The traditional paper-plastic lamination is to apply an adhesive on the plastic film, and make it bond with the paper printed matter after heating and pressing to form a paper-plastic product. The paper printed matter after lamination, because the surface is covered with a thin and transparent plastic film, makes the surface of the printed matter bright and smooth, the pattern is bright and bright, full of three-dimensional effect and does not change color for a long time. Laminating technology is widely used in the field of paper printed matter (such as handbags, book covers, advanced packaging, exquisite picture albums, etc.). ...
