Water-based reverse gloss oil and preparation method thereof

Abstract

The invention provides water-based reverse gloss oil and a preparation method thereof.The water-based reverse gloss oil comprises water-based base oil and water-based surface oil, the water-based base oil is composed of 82%-84% of water-based acrylic resin, 5%-6% of pure water, 4%-5% of propylene glycol, 3.3%-4.3% of a wetting flatting agent, 0.2%-0.5% of an amine neutralizer, 1%-1.5% of a water-based thickener and 1%-2% of bentonite; the water-based surface oil is prepared from 85-86% of water-based polyurethane resin, 5-6% of pure water, 4-5% of propylene glycol, 1-2% of silicon dioxide, 0.5-1% of a water-based defoaming agent, 0.5-1% of a wetting and leveling agent and 1-1.5% of a water-based thickening agent, high-flexibility and high-adhesion resin is selected as matrix resin, no solvent harmful to the human body is added, and the water-based surface oil can be used as a water-based paint for the water-based paint. The waterborne reverse gloss oil improves adhesion and flexibility after film formation, improves the drying speed of the gloss oil under an infrared lamp, greatly reduces VOC emission, also reduces the odor of a product, has good adhesion and flexibility, high gloss, fast drying, low residual odor and good reverse effect, can increase the aesthetic degree of the product when being printed on the product, and has good application prospects. And the protection effect on the paper is also improved.

Description

technical field [0001] The invention belongs to the technical field of polymer ink, and in particular relates to a water-based reverse varnish and a preparation method thereof. Background technique [0002] Reverse glazing (Pro-cure) is relative to traditional local glazing. In the past, no matter what kind of glazing method (flexo printing, screen printing or gravure printing) was used for partial glazing, the last glazing process must use partial glazing plate printing to achieve high-contrast effect of local graphics. Therefore, the registration accuracy of glazing and printing has become a key factor in the glazing process. The reverse glazing process breaks through the above laws, and solves the problem of positioning alignment. The process flow is as follows: [0003] Conventional printing must be completed before glazing, and the ink must be completely dried or cured; then, the non-high-gloss part of the design draft should be printed with transparent reverse primer...
