preparation example Construction

[0053] The present invention also provides the preparation method of the above-mentioned radiation-cured film-coated bright frosted paper, which is special in that: firstly prepare the above-mentioned frosted paint containing organic frosted particles, then carry out surface treatment on the film, and then apply the frosted paint on the film and use It is cured by radiation, and then the film is vacuum evaporated, and then the film with the frosted layer is compounded with the paper substrate through the film coating process, and finally the product is obtained by coating. The specific process includes: batching - film corona - film coating - vacuum evaporation - compounding - coating treatment - finished product.

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

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

Embodiment 1

[0064] In this example, the electron beam radiation curing process is used to prepare radiation-cured coated glossy frosted paper, and the paper substrate-225g coated composite white cardboard, the film layer-15μPET transfer base film, the frosted layer-electron beam cured frosted coating, bonding Agent layer-polyacrylic adhesive, top coat-waterborne polyurethane top coat, vapor deposition layer-aluminum vapor deposition layer were prepared.

[0065] Step 1: Ingredients

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

Embodiment 2

[0078] This example adopts the electron beam radiation curing process to prepare radiation-cured coated glossy matte paper, including: paper substrate-225g coated composite white cardboard, film layer-22 μ BOPP film, matte layer-electron beam cured matte coating, adhesive Layer-polyacrylic adhesive, top coat-waterborne polyurethane top coat, vapor deposition layer-aluminum vapor deposition layer.

[0079] Step 1: Ingredients

[0080] First, 25 parts of difunctional polyether acrylate, 20 parts of difunctional epoxy acrylate, 10 parts of methyl methacrylate, 10 parts of ethoxy ethyl acrylate, 10 parts of tripropylene glycol diacrylate, 10 parts 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 10-20min; then add 1.0 parts of defoamer, 2.0 parts of wetting ...

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...
