Abstract

The invention provides a matt prevention film waterborne matt varnish and a preparation method thereof. The matt prevention film waterborne matt varnish is prepared from the following components in percentage by mass: 50-80 percent of waterborne polyurethane dispersion, 10-30 percent of self-crosslinking acrylic acid emulsion, 5-10 percent of matting powder, 3-8 percent of waterborne wax emulsion,1-3 percent of wetting agent, 0.1-1 percent of defoamer, 0.1-1 percent of hand scratch-resistant agent and 1-5 percent of deionized water. The matt prevention film waterborne matt varnish has the advantages of high flexibility, difficulty in breaking, very low glossiness and high abrasion resistance after film formation and can replace a BOPP matt film covering product. The invention also provides the preparation method of the matt prevention film waterborne matt varnish.

Description

technical field [0001] The invention relates to a varnish on the surface of a printed matter, in particular to a water-based matte oil for an anti-matte film and a preparation method thereof. Background technique [0002] At present, in the printing industry, the surface treatment methods of printed matter mainly include glazing and film coating, and the main functions are protection, beauty, gloss and wear resistance. Varnish mainly uses ultraviolet curing varnish (UV oil), water-based varnish, solvent-based varnish, etc. With the increasing requirements for environmental protection, solvent-based products will gradually be eliminated, while water-based varnish is environmentally friendly and easy to use. characteristics, but it has the disadvantages of low strength and easy bursting. Paper-coated products have the characteristics of high strength and not easy to burst. They occupy a large market share in the surface treatment of paper printed matter, and most of the films...
