Description
Technical Field
The utility model relates to the field of multi-layer solid wood boards, in particular to a multi-layer solid wood board capable of preventing cracking.
Background
Natural materials, particularly wood, have been the main household materials from ancient times to date, and have been favored and seen by people. In the days of increasingly deficient natural resources and increasingly strong environmental protection consciousness, and the aesthetic consciousness of people is biased towards the nostalgic state, the natural solid wood material is more favored by people. Therefore, solid wood furniture processed from solid wood plays an important role in the field of high-grade furniture which has high requirements on aesthetic appearance.
However, the cost of the pure solid wood board manufactured by directly using the raw wood material integrally is too high, and the pure solid wood board is easy to deform in the using process, so that most of the existing solid wood furniture is manufactured by adopting multiple layers of solid wood boards. The multi-layer solid wood board is a board formed by hot-pressing a multi-layer thin wood board with an adhesive coating board surface according to a certain direction and form, and has excellent strength and stability. The high-quality solid wood multi-layer board has a uniform laminated structure, and the wood of each layer is selected from the same tree species and the same thickness; the glue used in the production of the multilayer solid wood floor is environment-friendly, and has high gluing quality, so that the multilayer solid wood floor has excellent gluing effect and longer service life.
After the existing multilayer solid wood boards are subjected to press molding, edges and sections of the multilayer solid wood boards are required to be polished to remove burrs and flanging after cutting and blanking, so that the multilayer solid wood boards can be used for manufacturing furniture. After finishing polishing, in order to eliminate the exposed and unattractive multi-layer wood board structural trace on the side surface and the cross section, the same wood strip lace as the board surface is ensured on the side surface and the cross section, the wood grain lace can be drawn on the side surface or the cross section formed by cutting and cutting materials in a hand drawing mode by an operator, and then the wood grain lace is painted integrally, so that the integral effect of the solid wood board is formed visually.
In practical use, it is found that although the surface layer of the multi-layer solid wood board is not easy to deform after finishing polishing and lacquering, the side surface and the section of the multi-layer solid wood board are easy to warp due to different stress between each layer of parts, and when conditions such as severe expansion and contraction caused by water absorption and moisture absorption, large temperature difference change, collision and impact during transportation occur, the stress release of each layer of the side surface and the section of the multi-layer solid wood board is different, and the edge position is easy to warp, so that the lacquer surface on the side surface is cracked.
After the paint surface is cracked, the appearance is seriously affected, and the waterproof and moistureproof performances of the multilayer solid wood board are also seriously affected, so that an additional paint repair process is required for the multilayer solid wood board after the paint surface is cracked. Thus, not only is a great deal of manpower and material resources wasted, but also the uncertainty can affect the normal production period and delivery date, and the experience of customers can be adversely affected, so that improvement is needed.

As shown in fig. 1, a cracking-resistant multi-layer solid wood board comprises a sealing layer 3, wherein the sealing layer 3 is fixed on the side surface of the multi-layer solid wood board 1 and completely covers the side surface of the multi-layer solid wood board 1, so that the multi-layer structure exposed from the side surface of the multi-layer solid wood board 1 is completely covered.
The surface of the entire multi-layer solid wood board 1 is provided with a paint layer 4, whereas on the side of the multi-layer solid wood board 1 the paint layer 4 is located on the side of the edge sealing layer 3 facing away from the multi-layer solid wood board 1. In the actual production process, edge sealing treatment is firstly carried out on the side face of the multilayer solid wood board 1, namely: the edge sealing layer 3 is fixed on the side face of the multilayer solid wood board 1, then the multilayer solid wood board 1 and the edge sealing layer 3 are taken as a whole to be polished, and finally the whole is painted. Because the edge sealing layer 3 is integrally arranged, all parts of the edge sealing layer 3 cannot deform and crack due to different stresses, and therefore the integrity of the surface paint surface of the multilayer solid wood board 1 with the edge sealing layer 3 is guaranteed.
Specifically, an adhesive layer 2 is further arranged between the multi-layer solid wood board 1 and the edge sealing layer 3, the edge sealing layer 3 is fixed on the side face of the multi-layer solid wood board 1 through the adhesive layer 2, and the adhesive layer 2 is composed of PUR glue.
Compared with traditional EVA, PA and other hot melt adhesives, the PUR adhesive has the characteristics of higher bonding strength, better water resistance, high temperature resistance and difficult fracture. The edge sealing machine can effectively avoid defects such as edge sealing cracking, deformation and the like, has smooth and elegant surface, and is beneficial to improving the quality and grade of products.
In actual production, a PUR hot melt adhesive machine can be used for heating and gluing, and the edge sealing layer 3 is bonded to the side surface of the multi-layer solid wood board 1 and then compacted by a pressing machine, so that firm bonding force is formed between the edge sealing layer 3 and the multi-layer solid wood board 1. In particular, the related materials and equipment for edge sealing treatment by using PUR glue are all the prior art, and the utility model does not relate to the improvement of materials and process methods.
The edge sealing layer 3 is made of PVC material, namely polyvinyl chloride universal plastic, and is an existing material with very wide application.
