Abstract

The invention relates to novel water-based paint for environment-friendly glassine and a preparation method of the novel water-based paint, and provides the novel water-based paint and the preparation method which are mainly aimed at solving the problems that at present, water-based paint for glassine is not large enough in adhesion, too high in coating hardness, poor in coating folding endurance, not complete in coating transfer and not wide in printing adaptability. The novel water-based paint is prepared from, by weight, 60-80 parts of water-based acrylic acid opaque emulsion, 10-20 parts of self-crosslinking solidified acrylic acid emulsion, 3-8 parts of calcium carbonate, 5-10 parts of water, 1.0-3.0 parts of water-based coalescing agent, 0.3-0.8 part of water-based defoaming agent, 0.5-1 part of water-based dispersing agent and 0.5-1 part of water-based wetting agent. The novel water-based paint has the advantages of being environmentally friendly, good in film forming property, high in glossiness, wide in printing adaptability and the like.

Description

technical field [0001] The invention relates to a novel environmental-friendly water-based paint for glass cardboard and a preparation method thereof. Background technique [0002] Glass cardboard is a special variety of coated processed paper. It uses the principle of casting to paste the base paper coated with special paint on the surface of a heated, highly polished chrome-plated drying cylinder with mirror luster, and peels off after drying. down the processed paper. Because the paper surface is as smooth and bright as glass, it is called glass paper. Glass cardboard has the following incomparable characteristics of other coated cardboards: 1. High gloss and opacity, strong reproducibility of printing gloss; Less ink, vivid images, strong three-dimensional effect, suitable for multi-color printing with the thinnest mesh line, rich texture; can significantly improve the quality and added value of printed matter; 3. The paper quality of glass cardboard has good tightness...
