Problems solved by technology

[0003] In the prior art, as a high-strength flat plate made of wood fiber and thermosetting resin through high-pressure polymerization, the anti-folding board has an obvious laminated structure. Specifically, the kraft paper treated with phenolic resin is bonded by thermocompression to obtain the substrate. The decorative paper treated with melamine is hot-pressed and glued on both sides of the substrate to obtain a complete anti-folding board. Since the combination of the decorative paper and the substrate is hot-pressed and glued, the weather resistance of the above board is poor. When used outdoors for a long time, it is easy to cause the decorative paper to fall off, which will affect the product quality and aesthetics

Embodiment 1

[0022] Such as figure 1 As shown, the weather-resistant and anti-folding board for outdoor use in this embodiment includes a substrate, and the outside of the substrate is coated with decorative paper treated with impregnated resin. The electron beam cured coating is composed of the following raw materials by weight percentage: polyurethane acrylic acid 50%, epoxy acrylic acid 7%, co-crosslinking agent 15%, hexanediol diacrylate 15%, light stabilizer 1%, flame retardant 3%, UV absorber 2%, antioxidant 5%, coupling agent 0.5%, leveling agent 0.5%, dispersant 1%, the above materials are stirred and mixed to obtain electron beam curing coating resin, wherein the co-crosslinking agent is Trimethylolpropane triacrylate, the light stabilizer is hindered amine light stabilizer.

Embodiment 2

[0024] The manufacturing method of the weather-resistant and anti-fold special board for outdoor use of embodiment 1 comprises the following steps:

[0025] A. Electron beam curing coating resin preparation: Add the following raw materials into the mixer by weight percentage, including 50% polyurethane acrylic acid, 7% epoxy acrylic acid, 15% trimethylolpropane triacrylate, and hexanediol diacrylate 15%, hindered amine light stabilizer 1%, flame retardant 3%, ultraviolet absorber 2%, antioxidant 5%, coupling agent 0.5%, leveling agent 0.5%, dispersant 1%, start the agitator and Heating to 50° C., stirring evenly, and vacuumizing to obtain an electron beam curing coating resin solution.

[0026] B. Impregnate the decorative paper with resin, dry and rewind to ensure that the obtained decorative paper has a uniform weight, a smooth surface, and the light fastness rating of the printing ink is not less than 6.

[0027] C. Glue coating and curing. Apply the electron beam curing c...

Embodiment 3

[0036] A method for manufacturing an outdoor weather-resistant and anti-folding board. On the basis of Embodiment 2, the manufacturing method of this embodiment has the following differences:

[0037] In step B, the grammage of the decorative paper before impregnation is 100 g / m2, the amount of glue applied during impregnation is 75 g / m2, the volatile matter is 3%, and the light fastness rating of the printing ink is grade 8 to ensure uniform impregnation of the decorative paper.

[0038] In step B, the impregnated resin is a mixture of melamine-formaldehyde resin and phenol-formaldehyde resin, wherein the mass percentage of melamine-formaldehyde resin is 50%, and the mass percentage of phenol-formaldehyde resin is 50%, so as to ensure the decoration after impregnation The paper retains its toughness while retaining its affinity for electron beam cured coating resins.

[0039] In step C, the coating thickness is 0.17mm; in step D, the substrate is made of fiberboard substrate im...

Abstract

The invention relates to an outdoor weather-proof compact laminate and a preparation method thereof. The outdoor weather-proof compact laminate comprises a base plate. An outer side of the base plateis coated by decorative paper treated by impregnating resin. The surface of the decorative paper is coated by an electron beam curing coating. Through laying the electron beam curing coating on the surface of the decorative paper of the compact laminate, the acquired compact laminate is high-temperature-resistant, boiling-water-resistant, and impact-resistant, has the more excellent weather resistance, and can be suitable for an outdoor environment better, so an application range of the compact laminate is greatly enlarged. An electron beam curing technology is applied to the compact laminate,so strong acid and strong alkali and solvent resistance on the surface of the compact laminate can be improved. The compact laminate has outdoor ultraviolet resistance and weather resistance which acommon compact laminate does not have.

Description

technical field [0001] The invention relates to the technical field of building decoration materials, in particular to a weather-resistant and anti-folding board for outdoor use and a preparation method thereof. Background technique [0002] Anti-fold special board has excellent stability and is easy to clean and maintain, so it has a wide range of applications. Anti-fold special board is widely used in large public places such as schools, hospitals, airports, stations, hotels, shopping malls, and office buildings. Kitchen countertops, vanity tops, dining tables, desks, door leaves, bathroom and toilet cubicles in public spaces, sinks, reception counters, lockers, ceilings, desks and office cubicles, etc. [0003] In the prior art, as a high-strength flat plate made of wood fiber and thermosetting resin through high-pressure polymerization, the anti-folding board has an obvious laminated structure. Specifically, the kraft paper treated with phenolic resin is bonded by thermo...
