Description
Technical Field
The invention belongs to the technical field of integrated plates, and particularly relates to a transparent polymer film veneer integrated plate, a manufacturing method thereof and a transparent adhesive applied to the transparent polymer film veneer integrated plate.
Background
The solid wood laminated board is a laminated board, also known as a finger-jointed board, a finger-jointed board or a laminated board, and is formed by lengthening narrow and short battens by an adhesive (part of board technology is tooth-shaped connection), transversely widening, and sanding the upper and lower surfaces. The solid wood integrated board is popular in the market due to the natural wood texture and less glue consumption.
The surface of the existing integrated board is treated by a transparent paint process, so that the definition of wood texture is ensured and the effect of protecting wood is achieved. However, the paint film products have poor wear and scratch resistance, and are easy to scratch and wear during production, transportation, furniture cutting and assembling and customer use, so that the product yield is low and the customer complaint rate is high. Meanwhile, the paint has large smell in the production process, does not accord with the current environmental protection concept, and has high paint cost.
The application of a transparent wear-resistant layer on the surface of the integrated board is an easily conceivable method for solving the above problems. The existing market transparent wear-resistant layer is generally impregnated bond paper and a polymer film, wherein the wear-resistant paper needs to be coated and attached on the laminated wood in a hot pressing mode, and the production process of the wear-resistant paper has more offline on the laminated wood and is not easy to control; the prior polymer film veneer is difficult to popularize in the market because the appearance effect of the veneer process is not ideal (the texture is not clear, bubbles and gaps are formed and the like).
Therefore, a novel veneer mode of the laminated board is provided, so that on the premise of meeting the requirement of displaying natural textures of the laminated material in a transparent mode, the defects that the wear resistance is poor, the smell is large, impregnated bond paper and a high polymer film veneer cannot clearly display textures and the like caused by the paint film product can be overcome.
Disclosure of Invention
In order to solve the problems in the prior art, the inventor of the present invention provides a solution for coating a layer of transparent polymer film on the surface of a solid wood substrate, so as to achieve the effect of clearly displaying the natural texture of the laminated wood. However, when the transparent polymer film is adhered to the surface of the integrated board by using the conventional polyurethane hot melt adhesive, the poor filling property of the adhesive can easily cause the generation of fog-like glue dots at the natural wood grains of the integrated board, which affects the definition of the wood grains and has poor appearance visual effect.
To this end, the inventors propose a transparent adhesive having a new composition, which has both filling properties and high light transmission; that is, when pasting transparent polymer film and covering in the surface of integrated board, under the prerequisite of guaranteeing the clear demonstration of wood grain, can also easily permeate among the timber pipe space of integrated board, reach the effect of filling the timber space, reducing the bubble and producing.
In order to achieve the purpose of the invention, the invention adopts the following technical scheme:

The filler is dispersed in a diluent, and exhibits high transparency and high light transmittance.
Preferably, the filler is selected from any one of alpha-cellulose, beta-cellulose and gamma-cellulose.
Further, the diluent can be any one selected from polyethylene glycol o-phenylphenyl ether acrylate, phenylphenol ethoxy acrylate and trimethylolpropane triacrylate; the photoinitiator can be any one selected from TPO photoinitiator, DETX photoinitiator and isopropyl thioxanthone; the coupling agent can be selected from any one of silane coupling agent and titanate coupling agent; the leveling agent can be selected from any one of organic siloxane and fluorocarbon leveling agents.
Therefore, the transparent adhesive provided by the invention can obviously improve the refractive index of the adhesive based on the use of the specific filler, so that the light transmittance can be obviously improved; the fluidity of the adhesive is properly increased when the adhesive flows, the filling property of the adhesive is ensured when the adhesive is static, and the adhesive can easily penetrate into gaps of wood ducts when being applied to the surface of a material with the gaps, such as wood, so that the effects of filling the gaps of the wood and reducing the generation of bubbles are achieved.
The transparent adhesive with the novel components has high light transmission and filling property, and is particularly suitable for integrated plates; therefore, the invention provides a transparent polymer film veneer integrated plate.
The transparent polymer film veneer integrated board comprises a solid wood integrated board, and a transparent adhesive layer and a polymer film veneer layer which are sequentially laminated on the solid wood integrated board; that is, the transparent adhesive layer adheres the polymer film veneer layer to the solid wood integrated board to form the transparent polymer film veneer integrated board.
Wherein, the material of the transparent adhesive layer is the transparent adhesive.
Further, the material of the polymer film facing layer is selected from any one of PVC, PE, PP, PET and PETG.
The solid wood integrated board is made of wood which is commonly sold in the market, and can be selected from any one of fir, rubber wood, pine, oak, red oak and ash.

At the moment, the transparent polymer film can be covered by adopting a rolling laminating mode to remove air bubbles, so that the phenomenon that the appearance display of lines is influenced due to the formation of air bubbles inside the subsequently manufactured transparent polymer film veneer integrated plate is avoided.
In step S4, the obtained multi-layer board is photo-cured, the transparent adhesive forms a transparent adhesive layer, and the transparent polymer film is adhered to the solid wood integrated board to form a polymer film facing layer.
Thus, the transparent polymer film veneer integrated plate can be obtained through the edge cutting operation of fixed length and width.
The light curing is performed by UV light curing.
