Water mist prevention UV (ultraviolet) gloss oil for gold card paper

Abstract

The invention discloses water mist prevention UV (ultraviolet) gloss oil for gold card paper, which is prepared from the following raw materials in parts by weight: 40-60 parts of epoxy UV resin, 5-15 parts of amino active matter, 20-40 parts of 1.6-hexanedioldiacrylate, 4-10 parts of photosensitizer, 1-6 parts of nanometer metallic oxide and 0.2-2 parts of lubricating flatting agent. In the invention, the formula of the existing water mist prevention UV gloss oil is adjusted, the nanometer metallic oxide is added in, as the nanometer metallic oxide particles are minimum, refraction and reflection of light rays can not be affected, thereby solving the problem of glossiness of patterns on the gold card paper, increasing the scraping-resisting performance of a forming film and improving the quality of the water mist prevention UV gloss oil.

Description

technical field [0001] The invention relates to a UV varnish, in particular to a waterproof fog UV varnish for gold cardboard. Background technique [0002] At present, polyethylene wax or modified polyethylene wax micropowder is commonly used in the waterproof fog UV varnish for gold cardboard on the market. Although this type of micropowder wax has the physical characteristics of water-proof fog, after use, it will cause the surface gloss of the UV varnish film to decrease, and in severe cases, it will cause a matte phenomenon, such as the existing hard coating used to hold high-end cigarettes. Cigarette boxes are mostly made of gold cardboard. The applicant compared the results before and after coating the hard cigarette boxes with waterproof and mist varnish, and found that the gloss of the hard cigarette boxes decreased by 15%-30% after being covered with micro-powder wax. %, seriously affecting the aesthetics and gloss of the original pattern. At the same time, durin...

Although this type of micropowder wax has the physical characteristics of water-proof fog, after use, it will cause the surface gloss of the UV varnish film to decrease, and in severe cases, it will cause a matte phenomenon, such as the existing hard coating used to hold high-end cigarettes. Cigarette boxes are mostly made of gold cardboard. The applicant compared the results before and after coating the hard cigarette boxes with waterproof and mist varnish, and found that the gloss of the hard cigarette boxes decreased by 15%-30% after being covered with micro-powder wax. %, seriously affecting the aesthetics and gloss of the original pattern

At the same time, during the cigarette boxing process, the existing waterproof and mist UV varnish for gold cardboard is affected by the temperature of the shredded tobacco. The varnish on the surface of the cigarette box is easy to get damp and soften, and it is easy to bond with the plastic film on the surface of the cigarette box, which affects the cigarette. The aesthetics and high-end feel of the box
