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 present invention relates to the field of dummy oil technology, in particular to a scratch-resistant UV dummy oil for a dummy film and a preparation method thereof. The scratch-resistant UV dummy oil for a dummy film of the present invention consists of 5-15 parts of epoxy Acrylic resin, 20-35 parts of modified acrylic resin, 50-65 parts of acrylic monomer, 10-15 parts of photoinitiator, 5-15 parts of matting agent, and 1-5 parts of auxiliary agents; The preparation method of the present invention is as follows: a. adding acrylic monomer and matting agent into a stirring pot for pre-dispersion, mixing and stirring evenly; b. continuing to add epoxy acrylic resin, modified acrylic resin, acrylic acid The monomer, photoinitiator and auxiliary agent are mixed and stirred evenly to obtain the oil; c, the oil can be filtered. The anti-scratch UV matte oil printing of the present invention has better anti-scratch performance on the matte film, and has delicate hand feeling, low matteness, good visual effect, good adhesion and good 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 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...
