Problems solved by technology

However, there are many problems behind the exquisite packaging, such as: companies are too pursuing luxury packaging, resulting in a substantial increase in packaging costs and a huge waste of national resources; in order to seize the market, various companies use a large number of non-degradable aluminum foil composite paper, mirror cardboard, etc. Non-environmentally friendly materials are used to form a wire drawing effect. This kind of packaging film is diff

Abstract

The invention discloses a hardened decorative film and a preparation method thereof. The hardened decorative film comprises a base material, the base material sequentially comprises a first PET film,a PVC film and a second PET film from inside to outside, and a surface hardened film is arranged on the second PET film; the two film layers are attached through glue. The surface hardened film is prepared by coating UV hardening liquid, and the hardening liquid is prepared from the following raw material components: 43 to 57 parts of modified water-based acrylate, 40 to 60 parts of ethyl acetate,11 to 17 parts of nano silicon dioxide, 1 to 3 parts of a photoinitiator, 0.8 to 1.5 parts of a fluorine-containing stain-resistant additive and 0.5 to 1 part of a fluorine-modified acrylic acid leveling agent, wherein the modified water-based acrylate is prepared by a reaction of carboxyethyl cellulose, carbon nanotubes and water-based acrylate. A micro gravure process is adopted for coating, and after coating, the coating is cured under UV light irradiation to form a hardened decorative film with stain resistance, scratch resistance and high strength. The invention has the advantages of reasonable proportioning design and higher practicability.

Description

technical field [0001] The invention relates to the field of decorative films, in particular to a hardened decorative film and a preparation method thereof. Background technique [0002] With the gradual improvement of people's living standards, surface decoration materials have also entered a period of rapid development. Among them, film materials such as PET film, OPP film, PC film, PVC film and various composite films are characterized by their stable production process, surface decoration patterns and It has various effects, simple application methods, and high cost performance, so it occupies a leading position in the market of new surface decoration materials. However, there are many problems behind the exquisite packaging, such as: companies are too pursuing luxury packaging, resulting in a substantial increase in packaging costs and a huge waste of national resources; in order to seize the market, various companies use a large number of non-degradable aluminum foil c...
