Example Embodiment

[0053] The present invention also provides the method for preparing the above-mentioned radiation-curable coated bright matte paper. The special feature is that the above-mentioned matte coating containing organic matte particles is first prepared, then the film is surface treated, and then the matte coating is coated on the film and used Radiation curing is performed, and then the film is vacuum vapor-deposited, and then the film with the frosted layer is compounded with the paper substrate through the laminating process, and finally the product is obtained through coating treatment. The specific process flow includes: ingredients-film corona-film coating-vacuum evaporation-composite-coating treatment-finished product.

[0054] Furthermore, the process can be optimized. The specific process steps are as follows:

[0055] Ingredients: first add the prepolymer and active diluent into the container according to weight percentage, control the stirring speed 200-500rpm, stir for 5-10mi...

Example Embodiment

[0063] Example 1:

[0064] In this embodiment, an electron beam radiation curing process is used to prepare a radiation-cured coated bright matte paper, a paper substrate-225g coated composite white cardboard, a film layer-15μPET transfer base film, a matte layer-electron beam curing matte coating, bonding The agent layer-polyacrylic acid adhesive, top coating-water-based polyurethane top coating, and vapor deposition layer-aluminum vapor deposition layer are prepared.

[0065] The first step: ingredients

[0066] First add 35 parts of bifunctional polyester acrylate, 35 parts of bifunctional urethane acrylate, 10 parts of dicyclopentyloxyethyl acrylate, and 15 parts of neopentyl glycol dipropoxylated diacrylate into the container , Control the stirring speed 200-500rpm, stir for 5-10min; then add 1.0 part of 5-20μm polyethylene micropowder into the container, control the stirring speed 800-1000rpm, stir for 10-20min; then add 0.5 part of defoamer 2. Add 2.0 parts of wetting agent ...

Example Embodiment

[0077] Example 2:

[0078] In this embodiment, an electron beam radiation curing process is used to prepare a radiation-cured coated bright matte paper, including: paper substrate-225g coated composite white cardboard, film layer-22μBOPP film, matte layer-electron beam curing matte coating, adhesive The layer-polyacrylic acid adhesive, top coating-water-based polyurethane top coating, vapor deposition layer-aluminum vapor deposition layer are prepared.

[0079] The first step: ingredients

[0080] First, 25 parts of bifunctional polyether acrylate, 20 parts of bifunctional epoxy acrylate, 10 parts of methyl methacrylate, 10 parts of ethoxyethyl acrylate, 10 parts of tripropylene glycol diacrylate, 10 parts of Add tetraethylene glycol diacrylate into the container, control the stirring speed at 200-500rpm and stir for 5-10min; then add 10 parts of polypropylene micropowder with a particle size of 5-20μm into the container, and control the stirring speed at 800-1000rpm , Stir for 10-...

Abstract

The invention discloses film-coated radiation-cured bright abrasive paper and a preparation method of the film-coated radiation-cured bright abrasive paper. The paper comprises a paper base material,an adhesive layer, an evaporation layer, a frosted layer, a film layer and a surface coating, wherein the frosted layer is prepared from a frosted coating added with organic frosted particles; the frosted coating is prepared from the following components in parts by weight: 20-70 parts of a prepolymer, 20-70 parts of an active diluent, 1.0-20.0 parts of organic frosted particles, 0-5.0 parts of aphotoinitiator and 1.0-5.0 parts of an auxiliary agent. By means of the technical scheme, the paper has bright bright crystal effect, strong visual impact effect, visual impression of frosted and gravel, smooth surface, low energy consumption, zero emission of volatile organic compounds in the technological process, and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of packaging printing materials and decorative materials, and in particular relates to a preparation method of film-coated radiation-cured glossy frosted paper. Background technique [0002] Matte paper is widely used in various high-end packaging because of its noble and beautiful shiny sandy feeling and stable and reliable anti-counterfeiting properties. The matte effect of existing materials can form uneven structures on the surface of the substrate through different treatment methods. When the light hits the surface, diffuse reflection is formed, showing a foggy matte visual effect. The commonly used treatment methods mainly include printing, rubbing, Embossing, coating, etc. 1) The printing method is to print the matte ink on the substrate by means of screen, gravure, etc. During the curing process of the ink, due to the change of the surface energy of the filler, the film-forming substance will be loc...
