[0002] Existing decorative panels generally include paint panels, melamine panels, and the like.

[0003] Painted boards are made by grinding the board surface six to nine times (different manufacturers have different times, the more times, the higher the process requirements, the higher the cost), applying primer, drying, polishing (three bases, two sides, one light), and baking at high temperature. However, the production cycle of painted boards is too long, the process level is high, the scrap rate is high, so the price is high, and they are afraid of bumps and scratches. Once damaged, it is difficult to repair and needs to be replaced as a whole. There are defects such as poor protection and light transmittance, and the production process is easy to pollute the environment.

[0004] Melamine board is a board with melamine impregnated paper. Melamine impregnated paper, also known as "melamine" paper, is a plain base paper or printed decorative paper impregnated with amino resin (melamine formaldehyde resin and urea-formaldehyde resin) and dried to a certain degree. It has a certain resin content and volatile content. It is hot-pressed and glued to the board to form a board with decorative properties. It can be used to beautify the appearance of the board, improve the use value, and simplify the board production process (avoid spray painting, brushing and other processes). However, the existing melamine board has poor surface anti-fouling performance, which is not conducive to cleaning and maintenance, and the maintenance cost of the board is high.

[0026] Example

[0027] like Figure 1As shown, this embodiment provides a board with a multi-layer structure, including: a substrate 1; a first layer of melamine paper 2 is arranged on the upper surface of the substrate 1, a first UV adhesion bottom layer 3 is arranged on the upper surface of the first layer of melamine paper 2, and a first microcrystalline layer 4 is arranged on the upper surface of the first UV adhesion bottom layer 3; a second layer of melamine paper 5 is arranged on the lower surface of the substrate 1, a second UV adhesion bottom layer 6 is arranged on the lower surface of the second layer of melamine paper 5, and a second microcrystalline layer 7 is arranged on the lower surface of the second UV adhesion bottom layer 6. By sequentially arranging melamine paper, UV adhesion bottom layer and microcrystalline layer on the upper and lower surfaces of the substrate, the anti-fouling performance of the board is greatly improved, which is convenient for cleaning and maintenance, and reduces the maintenance cost of the board; and the upper and lower surfaces of the board are evenly stressed, more stable, not easy to deform, and the service life of the board is extended; by arranging the microcrystalline layer, the board can improve the texture of the board while meeting the aesthetics of the decorative board; in addition, the processing technology of the board is simple, the production cycle is short, and it is conducive to large-scale production and promotion.

[0028] The material of the microcrystalline layer is microcrystalline film. Microcrystalline film is a film with a micron-level structure. Many tiny prism-like structures are formed on the surface of the film, which can reflect, scatter, refract and absorb light to make the light softer. Microcrystalline film has the characteristics of high light transmittance, strong anti-pollution, good scratch resistance and high color stability.

[0029] The microcrystalline film is arranged on the outer surface of the substrate 1, so that the board has a dense low-pore surface, stains are difficult to penetrate, the anti-fouling performance of the board is greatly increased, and it is not afraid of erosion by dust and fingerprints, and it is easy to clean and maintain; in addition, the surface of the board has a high-grade matte texture and a comfortable feel, which can be well used in the manufacture of household items.

[0030] The UV adhesive base layer can be selected from commercially available UV resins (photosensitive resins) according to the needs. It is mainly composed of polymer monomers and prepolymers, in which light (ultraviolet light) initiators, or photosensitizers, are added. When exposed to ultraviolet light of a certain wavelength, it will immediately cause a polymerization reaction and complete the solidification conversion. It has strong adhesion to melamine paper, short curing time, fast construction speed and is more environmentally friendly.

[0031] Optionally, melamine paper, UV adhesive bottom layer and microcrystalline layer are provided on one or both sides of the substrate 1. In this embodiment, melamine paper, UV adhesive bottom layer and microcrystalline layer are provided on the upper and lower surfaces of the substrate 1, so that the board is evenly stressed, more stable and less prone to deformation.

[0032] The thickness of the UV adhesion bottom layer and the microcrystalline layer is not limited and can be set according to actual needs. In this embodiment, the first UV adhesion bottom layer 3 and the second UV adhesion bottom layer 6 have the same thickness, and the first microcrystalline layer 4 and the second microcrystalline layer 7 have the same thickness, so that the force on both sides of the plate is uniform and the stability is higher.

[0033] In this embodiment, a first UV oil layer is disposed between the first UV adhesive bottom layer 3 and the first microcrystalline layer 4 .

[0034] In this embodiment, a second UV oil layer is disposed between the second UV adhesion bottom layer 6 and the second microcrystalline layer 7 .

[0035] UV oil is a transparent coating. After being irradiated by UV lamp, it changes from liquid to solid, and then achieves surface hardening, which is scratch-resistant. UV oil has excellent adhesion and fast curing speed. Applying UV oil between the UV adhesive bottom layer and the microcrystalline layer greatly increases the adhesion between the two.

[0036] In this embodiment, the first layer of melamine paper 2 is bonded to the upper surface of the substrate 1 by heat pressing.

[0037] In this embodiment, the second layer of melamine paper 5 is bonded to the lower surface of the substrate 1 by heat pressing.

[0038] In this embodiment, the first layer of melamine paper 2 and the second layer of melamine paper 5 are any one of a solid color structure and a patterned color structure.

[0039] In this embodiment, the substrate 1 includes: one or more of density board, European pine board, particle board, bamboo fragrance board, bamboo fiberboard, solid wood board, and finger-jointed board.

[0040] The substrate 1 is not limited to the above-mentioned form, and other structures of the substrate 1 can also be used. For example, the substrate 1 includes: a middle solid wood board and bamboo fiberboards on both sides. The bamboo fiberboards are respectively bonded to the two sides of the middle solid wood board by white glue. The support of the bamboo fiberboard is strong and can effectively prevent the board from deforming. The white glue is used for bonding, which has high bonding strength, good toughness and durability. Alternatively, the substrate 1 includes: a middle solid wood board and solid wood diagonal boards on both sides. The solid wood diagonal boards on both sides are split structures and are bonded to the two sides of the middle solid wood board by white glue, which is conducive to timely releasing the internal stress of the middle single solid wood board and is not easy to deform. It can be seen that the substrate 11 can have many forms, which will not be repeated here.

[0041] The thickness of the substrate 1 is not limited and can be set according to actual needs. In this embodiment, the thickness of the substrate 1 is 0.1 cm-3 cm.

[0042] The processing technology of the utility model is as follows:

[0043] Melamine paper is pressed on the surface of substrate 1, UV adhesion base is rolled on the surface of the pressed melamine paper, cured by LED lamp, mercury lamp or gallium lamp, UV oil is rolled, and microcrystalline film is pressed out by a molding machine. The light source of the molding machine can be LED lamp, mercury lamp or gallium lamp, and the plate is obtained after the mercury lamp is completely cured. By sequentially arranging melamine paper, UV adhesion base layer and microcrystalline layer on the upper and lower surfaces of the substrate, the anti-fouling performance of the plate is greatly improved, which is convenient for cleaning and maintenance, and reduces the maintenance cost of the plate; moreover, the upper and lower surfaces of the plate are evenly stressed, more stable, not easy to deform, and the service life of the plate is extended; by arranging the microcrystalline layer, the plate can meet the aesthetics of the decorative plate while also improving the texture of the plate; in addition, the plate has a simple processing technology and a short production cycle, which is conducive to large-scale production and promotion, and is used for the manufacture of household products.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
