Problems solved by technology

However, most of the UV matte oils currently on the market are added with inorganic silica-type matting powder. The larger the particle size of this inorganic matting powder, the better the matting efficiency. When the coating film dries, the tiny particles of fumed silica will The surface of the coating film forms a micro-rough surface to reduce the reflection of light to obtain a matte appearance. This kind of inorganic matting powder is only filled in the coating and does not participate in the reaction. Under the action of external force, it is easy to be scratched off, showing poor scratch resistance. In addition, the adhesion on the dumb film is not good

Abstract

The invention relates to the field of matt varnish, and especially relates to scraping-resistant UV matt varnish applied to matt membranes and a preparation method thereof. The scraping-resistant UV matt varnish applied to matt membranes consists of, in parts by weight, 5-15 parts of epoxy acrylic resin, 20-35 parts of modified acrylic resin, 50-65 parts of an acrylic acid monomer, 10-15 parts of a photoinitiator, 5-15 parts of a matting agent, and 1-5 parts of an auxiliary agent. The preparation method comprises: a, adding the acrylic acid monomer and the matting agent into a stirring pot to pre-disperse, and mixing uniformly with stirring; b, continuing to add epoxy acrylic resin, modified acrylic resin, the acrylic acid monomer, the photoinitiator and the auxiliary agent into the stirring pot, and mixing uniformly with stirring to prepare a varnish material; and c, filtering the varnish material, so as to obtain the matt varnish. The scraping-resistant UV matt varnish has relatively good scraping resistance when applied to matt membranes, and is fine in handfeel, low in matt degree, excellent in visual effect, excellent in adhesive force and excellent in wear resistance.

Description

technical field [0001] The invention relates to the technical field of UV matte oil, in particular to a scratch-resistant UV matte oil used for matte films and a preparation method thereof. Background technique [0002] With the development of society, people now have higher and higher requirements for the appearance of paper products such as matte effect, and because of its special matte effect, good leveling and good hand feeling, UV matte oil is widely used Applied to various packaging manufacturers. However, most of the UV matte oils currently on the market are added with inorganic silica-type matting powder. The larger the particle size of this type of inorganic matting powder, the better the matting efficiency. When the coating film dries, the tiny particles of fumed silica will The surface of the coating film forms a micro-rough surface to reduce the reflection of light to obtain a matte appearance. This kind of inorganic matting powder is only filled in the coating ...
