Problems solved by technology

[0002] The current general-purpose water-soluble UV primer is basically composed of low glass transition temperature acrylic series emulsion and solid acrylic resin. When using paper, its adhesion is difficult to meet the requirements, especially for gold and silver, when the ink layer is scratched by fingers or other sharp objects, the entire ink layer will fall off

Embodiment Construction

[0008] Specific implementation plan

[0009] When the product is prepared by the present invention, a high-speed disperser is generally selected. When the rotation speed of the stirring cylinder reaches 100-200 revolutions per minute, according to the performance of the set UV primer, the water, solvent, Acrylic resin liquid, acrylic emulsion, acrylic hydrosol, water-based additives, etc. are added to the reaction tank for moderate mixing, then adjust the rotation speed to 400 revolutions per minute, keep stirring for 3 hours, and filter with 120 mesh filter cloth to prepare the finished product. Among them, deionized water can adjust viscosity, acrylic resin liquid and acrylic emulsion can adjust solid content and gloss, and acrylic hydrosol can adjust content and adhesion.

[0010] The following is a non-limiting embodiment of the present invention. The specific ratio can be changed at any time according to the performance provided by the user: Weigh 16% of the total weight of a...

Abstract

The invention is a kind of paper foundation oil, and the components of its raw material in percent include crylic acid resin liquor 15-20, acrylic emulsion 25-30 and deionized water 10-20, acrylic acid hydrosol or power water adhesive glue30-35, defoaming agent 0.3-0.8, thickening agent 0.5-3, levelling agent 0.1-1.5 and other water assistants, isopropyl alcohol, glycol and other solvents 3-5. The prepared UV foundation oil has weak toxicity and smell, a little environmental pollution, strong adhesive force, easy storage and good use stability, especially implementing the purpose: effectively solving the problem of the ability of protecting the fuscous or gold and argent wrapping paper against folding and scratching of acute matters. When using standard adhesive tape paper to detect adhesive force and tear, it achieves the effect of not falling off and not falling off of the whole piece of gold and argent paper at the time of scratching by acute matters.

Description

Technical field [0001] The invention relates to an oil for paper, in particular to a primer for paper, in particular to a water-based primer matched with an ultraviolet curable oil (UV oil for short) coated on the surface of a packaging cardboard. Background technique [0002] At present, the general water-soluble UV primer is basically composed of low glass transition temperature acrylic emulsion and solid acrylic resin. This UV primer is used in packaging printed with dark ink or ink with lower binder content. When paper, its adhesion is difficult to meet the requirements, especially for gold and silver. In the case of fingers or other sharp objects, the ink layer will fall off. China Patent Application No. ZL00117402.9 "Preparation Method of Water-based Paper Varnish" is an example. This method uses acrylic monomers or unsaturated monomers with high acid value and low molecular weight acrylic resins as dispersion resins. Anionic and nonionic two-in-one surfactants are used as ...
