Description

Technical Field

[0001] The utility model relates to the technical field of decorative wall panels, in particular to an indoor decorative wall panel. Background Art

[0002] Currently, existing decorative wall panels are generally painted on the wall panel surface to form a base coat, then the wall panel surface is decorated to form a decorative layer, and finally treated by thermal curing or UV curing technology to form a cured layer. Although the wall panels obtained by this existing process meet national standards for surface effects and related performance, the UV curing process requires the use of photoinitiators, which may cause chemical pollution during the production and processing process. In addition, the curing degree of the UV cured layer is not high, only 40-70%, and there is room for further improvement. Summary of the Invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to more clearly illustrate the technical solutions in the embodiments of the present application, the following briefly introduces the drawings required for use in the description of the embodiments. Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without any creative work.

[0019] Figure 1 It is a structural schematic diagram of an interior decorative wall panel described in Example 1 of the present utility model.

[0020] Figure 2 It is a structural schematic diagram of an interior decorative wall panel described in Example 2 of the present utility model. DETAILED DESCRIPTION

[0021] The technical solution of the present utility model is described in detail below with reference to the accompanying drawings and embodiments.

[0022] See Figure 1 As shown, Example 1 of the present application provides an interior decorative wall panel, including:

[0023] substrate1;

[0024] UV primer layer 2, provided on the top surface of the substrate 1;

[0025] A decorative layer 3 is provided on the top surface of the UV primer layer 2;

[0026] The EB top coating layer 4 is provided on the top surface of the decorative layer 3 .

[0027] After a UV primer layer 2 and a decorative layer 3 are sequentially provided on the top surface of a substrate 1, an EB top coating layer 4 formed by EB electron beam curing treatment is used to replace the traditional UV curing layer. The curing degree of the EB top coating layer 4 reaches more than 99%, and it can be firmly adhered to the substrate 1 with high stability. When using EB technology, no photoinitiator is required, and the resin reaction can be directly initiated to form the EB top coating layer 4. The formula is safer, the formula has a higher degree of freedom, pollution is avoided, energy is saved and carbon is reduced, and it is practical and convenient.

[0028] In this embodiment 1, the EB top coating 4 is formed by performing EB electron beam curing treatment on the top surface of the substrate 1 using an electron curtain accelerator.

[0029] Specifically, the formation principle of the EB topcoat layer 4 is:

[0030] The electron curtain accelerator is started to generate an electron beam and lead it to penetrate the paint surface of the interior decoration wall panel, and then the paint surface forms multiple free radicals, and then the free radicals react chemically with each other to form a dense EB surface coating 4 on the surface of the interior decoration wall panel.

[0031] More specifically, after using the EB surface coating 4 formed by EB electron beam curing treatment to replace the traditional UV curing layer, in addition to the above-mentioned beneficial effects, the interior decorative wall panels of the present application are better than traditional decorative wall panels in surface hardness / yellowing resistance / graffiti resistance / acid and alkali resistance / scratch resistance, and are more in line with people's usage needs.

[0032] Furthermore, the substrate 1 is made of SPC board or calcium silicate board. Using SPC board or calcium silicate board can make the fire protection grade of interior decorative wallboard reach Class B or above, among which the fire protection grade of calcium silicate board can reach Class A or above.

[0033] Furthermore, in this embodiment 1, the substrate 1 can also be made of one of particleboard, plywood, density board, and OSB board according to specific performance requirements.

[0034] Furthermore, the decorative layer 3 includes a printing layer 31 coated on the UV primer layer 2 and an EIR texture layer 32 provided on the top surface of the printing layer 31 .

[0035] Specifically, the texture of the EIR texture layer 32 is a concave-convex texture with varying convexities (not shown in the figure).

[0036] In this embodiment 1, the printing layer 31 is formed by using a digital inkjet printer to perform 6D digital inkjet printing on the top surface of the substrate 1.

[0037] Specifically, in this embodiment 1, the EIR texture layer 32 uses EIR technology to accurately copy the detailed texture and pattern information of the actual object to the surface of the wall panel to form a concave and convex texture, thereby making the visual effect of the wall panel more natural, realistic and gorgeous.

[0038] In this embodiment 1, the inkjet processing technology and the EIR processing technology are commonly used processing techniques in this field. The layer structure formed by the processing is a common structure in this field. It is an existing technology that is easily known to those skilled in the art and will not be described in detail here.

[0039] Furthermore, the paint used for the EB topcoat 4 is either a color paint or a varnish.

[0040] In this embodiment 1, if the EB top coating 4 needs to be transparent, varnish can be selected as the paint of the EB top coating 4. If the EB top coating 4 needs to be colorful, corresponding colored paint can be selected as the paint of the EB top coating 4.

[0041] Furthermore, the curing degree of the EB topcoat layer 4 is greater than 99%.

[0042] This application also provides Example 2. In Example 2, this example is basically the same as Example 1. For the sake of simplicity, only the main structure differences from Example 1 are described. The parts not described in this example are the same as those in Example 1, with the following differences:

[0043] The bottom surface of the substrate 1 is further provided with a UV primer layer 2 and an EB top layer 4 in sequence.

[0044] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure made using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
