Abstract

The invention discloses a matte PET (Polyethylene Terephthalate) film for a decorative sheet and a preparation method thereof. The matte PET film comprises a transparent PET film and a UV (Ultraviolet) light-cured coating coated on the transparent PET film, wherein the UV light-cured coating is used as a matte coating, and the UV light-cured coating is composed of a polyacrylate polymer with a crosslinking degree of 1-30%, a thermoplastic acrylate polymer with a molecular weight of 10000-200000, an acrylate monomer, acrylic resin, a photo initiator and an auxiliary agent, wherein the acrylatemonomer and the acrylic resin are UV crosslinkable. The provided matte PET film can ensure the transparency of a product and has a good matte effect.

Description

technical field [0001] The invention relates to a matte film, in particular to a matte PET film used for decorative sheets and a preparation method thereof. Background technique [0002] Plastic sheet occupies a dominant position in the new surface decoration material market due to its simple production process, various surface decoration patterns and effects, simple use method, and high cost performance. The film materials used for decorative sheets mainly include PVC film and PET film. And composite films, etc., are widely used in indoor and furniture decoration, decoration industry, aircraft interior membrane, cabin membrane and other fields. [0003] Decorative sheets can be divided into two categories according to their luminosity: matte or matte, glossy or mirror. Among them, the production methods of decorative sheets with matte or matte effects mainly include: [0004] (1) Add matting powder in the sheet production process to obtain a plastic sheet with a matte effe...
