Wood film laminated acrylic panel manufacturing method {WOODEN MEMBRANE LAYERED ACRYLIC PANEL MANUFACTURING METHOD}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing an acrylic panel used for interior finishing materials for buildings, various lightweight structures, lighting fixtures, and the like, wherein an acrylic panel is formed by stacking a wooden film body 11 between a pair of acrylic plates 10. The low viscosity adhesive liquid 12 diluted with an organic solvent is impregnated on the adhesive surface of the wooden film body 11 to induce primary adhesion between the acrylic plate 10 and the wooden film body 11 and then press-press. Pressed at (30) to form a smooth and intimate adhesive surface.

Acrylic plates are easy to process, lightweight, and relatively freely molded, so that they are widely used in the manufacture of interior finishing materials, as well as signboards, lighting fixtures, and various sundries.

In particular, transparent or semi-transparent acrylic plates have a relatively low brittle fracture property, so they are commonly used as substitutes for glass plates.As a result, various resin sheets, papers, or laminated wood are attached to the transparent or translucent acrylic plates. By expressing the pattern, various acrylic plate processed products have been developed to secure aesthetics and commerciality.

Among the processed materials of acrylic plate, the wooden film body which contains physical materials such as wood thin plate cut to the fine thickness of wood or paper made from wood pulp as the main raw material has a unique natural and beautiful pattern. Due to the acryl plate adhesion material, Patent No. 916234 and Utility Model Registration No. 400262 are mentioned as the acrylic film processing technology applied to the wood film body.

Patent No. 916234 and Utility Model Registration No. 400262 disclose that a wooden film sheet adhered to an acrylic plate is made by applying a thin wooden plate and a paper sheet respectively but the basic lamination or attachment method is substantially the same , A quick drying adhesive is first applied to both sides of the neck of a neck wrapper and dried to form a rubber layer or a resin layer, that is, a melted layer at the time of heat fusion bonding, then laminated between a pair of acrylic plates, .

Therefore, heating is inevitably accompanied in the process of attaching the wood film body to the acrylic plate, which may cause structural deformation such as bending and torsion due to the characteristics of the acrylic plate, which is weak to heat. Even if this is minimized, there is a serious problem that unnecessary hardening, glossiness and transparency decrease due to thermal deformation of the acrylic plate surface.

In order to solve this problem, it is possible to consider a method of applying a common adhesive rather than heat-sealing the wood film body and the acrylic plate, but this is a general surface finish using a synthetic resin film or the like As a technique for communicating, not only problems such as bubbles remaining in the adhesive surface and poor adhesion, but also unnecessary stress is generated in the adhesive target film between the bonding process itself or the drying and curing process of the adhesive, which is a post-treatment process. Serious problems may arise that are transmitted and the acrylic plate is deformed.

That is, in adhering the film to the acrylic plate, a tensile force is applied to the outer portion of the film to smoothly develop the film. At this time, the acrylic plate is bent or twisted while the tensile-deformed film is contracted and restored after adhesion.

In addition, since the wooden film body such as the wooden thin plate and the Korean paper can not form a completely smooth surface due to the nature of the tissue, a uniform and uniform bonding state can be formed by the conventional bonding system And there is a problem that the neck of the neck is broken during the bonding process.

In addition, regardless of thermal fusion and adhesion, in a conventional acrylic film with a wooden film body, a rubber or resin solute that forms a fusion layer or an adhesive layer as an active ingredient of the adhesive exhibits substantial adhesion. Is a typical combustible material. When the final product is made of acrylic plate, it is easily burned due to the friction of the cutting tool in the process of cutting the acrylic plate, so the cutting part is discolored or excessive scrap is formed on the cutting part. There is a serious problem that requires a separate post-treatment process such as work.

In particular, it is possible to freely set the cutting linear shape and to perform the rapid work, so that the rubber and the resin solute in the adhesive are fiercely burned during the processing by the laser cutting, which has recently been spotlighted, so that the discoloration and thermal deformation are excessively enlarged, .

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and in the method of manufacturing an acrylic panel having a wooden film body 11 attached between a pair of acrylic plates 10, 85 weights of a liquid organic solvent Applying the adhesive liquid 12 mixed with% to 90% by weight and 10% to 15% by weight of the solute, and adhered to the wood film body 11 between a pair of acrylic plate 10 to the acrylic plate 10 laminate Comprising the step of passing through the acrylic plate 10 laminated body between a pair of the contact roller 20, the adhesive surface between the acrylic plate 10 and the wood film body 11 is in close contact and the air layer in the adhesive surface to remove the acrylic Comprising the plate 10 and the acrylic plate 10, by pressing the adhesive press 30 to compress the wood film body 11 structure to compress the acrylic plate 10 and the wood film body 11 The adhesive layer 12 is dried by smoothing the adhesive surface between the layers and removing residual bubbles in the adhesive surface. Wood film body laminated acrylic panel manufacturing method characterized in that the step of completing the board.

In addition, the liquid organic solvent is a wood film laminated acrylic panel manufacturing method, characterized in that selected from the group consisting of toluene, cyclohexane, normal hexane, methyl ethyl ketone, acetone or a mixture thereof.

Through the present invention, in the manufacture of the laminated acrylic panel of the wood film body 11, not only the close adhesion is possible while minimizing the residual amount of the adhesive solute in the adhesive surface, but also the adhesion failure such as bubble residue in the adhesive surface can be effectively suppressed.

In particular, since the integral heating process is excluded when the wood film body 11 and the acrylic plate 10 are attached, side effects such as thermal denaturation and gloss reduction of the acrylic plate 10 can be fundamentally blocked, and the beautiful surface state of the finished product. Can be effectively maintained.

In addition, by minimizing the residual adhesive solute in the finished acrylic panel it is possible to suppress the combustion phenomenon generated during the cutting process and to improve the workability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a partially cutaway perspective view showing the layer structure of a laminated film of a wooden film body 11 manufactured according to the present invention, wherein the present invention is shown between a pair of acrylic plates 10 as shown. The wood film body 11 is laminated | stacked closely, and it is for manufacturing the board | plate material integrated.

In the illustrated embodiment, a wood plate material of finely laminated wood is applied as the wood film body 11, and at least one of the pair of acrylic plates 10 is a transparent or semi-transparent acrylic plate 10 applied to the finished acrylic. It is configured to express natural wood grain pattern on the panel.

FIG. 2 is a cross-sectional view of the present invention, as shown in the enlarged in the ellipse of the figure, the adhesive liquid 12 cured in the compressed state of the wood film body 11 between the pair of acrylic plates 10 It can be seen that together with the forming a smooth adhesive surface.

Such a lamination and adhesion state can be achieved through the process as shown in FIG. 3, which will be described in detail as follows.

As shown in FIG. 3, the present invention is disclosed by first bonding a wooden film body 11 between a pair of acrylic plates 10 to form an acrylic plate 10 laminate, wherein the acrylic plate 10 and the wooden film body are formed. The low viscosity adhesive liquid 12 is used for the adhesion of the (11), and is bonded to the acrylic plate 10 in a state where the adhesive liquid 12 is impregnated in the tissue of the wood film body 11.

In the embodiment shown in FIG. 3, the wood film body 11 is adhered to the upper surface of the acrylic plate 10 in the lower layer, and then the acrylic plate 10 in the upper layer is sequentially adhered, where the application of the adhesive liquid 12 is performed. The acrylic plate 10 or the wooden film body 11 may be applied to the acrylic film 10. However, in consideration of the flexibility of the wooden film body 11, which is a thin plate, the adhesive liquid 12 is spray-coated to the lower acrylic plate 10, After the wood film body 11 is adhered, a method of spray-coating the adhesive liquid 12 on the upper surface of the wood film body 11 to be adhered is preferable to bond the upper acrylic plate 10.

In addition, the wood film body 11 easily penetrates the adhesive film 12 of the present invention, which is a low-viscosity liquid, due to its structure, and thus simply mounts the wood film body 11 on the lower acrylic plate 10. The adhesive liquid 12 impregnated in the wooden film body 11 in the process of contacting the upper acrylic plate 10 after spray-coating the adhesive liquid 12 on the upper surface of the wooden film body 11 in the wooden film body 11 A diffusion surface may be formed on both sides to form an adhesive surface between the upper and lower acrylic plates 10 and the wood film body 11.

The adhesive liquid 12 applied to the present invention is different from the conventional adhesives in which an organic solvent and a rubber or resin solute are mixed, and their properties. A large amount of the organic solvent is contained to form a low-viscosity liquid. The sieve 11 is to allow easy penetration into the tissue.

Organic solvents applied to the adhesive solution 12 of the present invention include toluene, cyclohexane, normal hexane, methyl ethyl ketone or acetone, and their Mixtures may be applied.

In addition, the solute of the adhesive solution 12 may be a rubber-based solute and a phenol resin as a solute-based solute. These organic solvents and solutes are components used in conventional oil-based adhesives. The composition ratio of the solute is 70% to 80% by weight and 20% to 30% by weight, respectively, and is not only large in viscosity, but also contains a relatively large amount of solute, so that an excessive solid is formed on the adhesive surface when it is dried after adhesion. In the present invention, by applying a low-viscosity adhesive solution (12) mixed with 85% to 90% by weight of the liquid organic solvent and 10% to 15% by weight of the solute to suppress the formation of excessive solids after adhesion and when applying the adhesive solution 12 Easily penetrated into the film forming body 11 was made possible.

Considering that the composition ratio of the solute in the conventional oil-based adhesive is 20% by weight to 30% by weight, and the composition ratio of the solute in the adhesive liquid 12 of the present invention is 10% by weight to 15% by weight, there is a large difference in solute content at first glance. Although it may appear that there is no, the solute composition ratio of the present invention can be achieved by adding twice the organic solvent as compared to the conventional oil-based adhesive, substantially varying the viscosity and solids residual amount of the adhesive liquid 12 Will be displayed.

The adhesive solution 12 of the present invention may be formed by mixing the same amount of an organic solvent such as toluene in a commercial adhesive, or may be prepared by mixing an organic solvent and a solute in the above-described composition ratio in the initial manufacturing step of the adhesive. In the case of a commercial adhesive, a plurality of organic solvents are generally used in a mixed state, and when mixing the organic solvent with a commercial adhesive, it is preferable to select and dilute the main organic solvent in the adhesive.

Since the adhesive liquid 12 of the present invention has a relatively low content of rubber or resin solute, which is an active ingredient, as compared with a conventional adhesive, it may be misunderstood that the adhesive force will be lowered. Rather, considering that the wood film body 11 has a high porosity ratio and has a loose structure and an irregular surface as in the enlarged left ellipse of FIG. Since the wooden membrane body 11 can be smoothly penetrated into the tissue and it is advantageous for rapid diffusion in the tissue and formation of a highly smooth adhesive surface through the compression press 30 to be described later, there is no problem in the expression of the desired adhesive force. do.

As such, when the wooden film body 11 is bonded between the pair of acrylic plates 10 and the acrylic plate 10 laminate is completed, the acrylic plate 10 laminate is passed between the pair of contact rollers 20 to accompany the acrylic plate 10. The adhesive surface between the 10 and the wood film body 11 is brought into close contact with each other and the air layer in the adhesive surface is excluded to form the acrylic plate 10 adherent.

As shown in FIG. 3, the acrylic plate 10 laminate is processed into an acrylic plate 10 adhesive body while passing through a pair of adhesive rollers 20 rotating in opposite directions, in order to ensure productivity in the mass production application of the present invention. When the rotational speed of the adhesion roller 20 and the passing speed of the acrylic plate 10 laminate are set high, friction heat may be generated in the adhesion roller 20, and thus the surface of the acrylic plate 10 may be modified. The surface of the contact roller 20 may be cooled in such a manner as to circulate the cooling water.

When the acrylic plate 10 adherend is completed through the adhesion roller 20, the acrylic plate 10 adherend is pressed by the pressing press 30, so that the wooden film body ( 11) by compressing the tissue to smooth the adhesive surface between the acrylic plate 10 and the wooden film body 11 and to remove residual bubbles in the adhesive surface, as shown in the figure, a plurality of acrylic plates ( 10) It can also be put into the pressing press 30 in a state in which the adhesive body is laminated, and by maintaining this state for a predetermined time to dry and cure the adhesive liquid 12, as shown in Figure 4 solidly integrated and beautiful pattern The represented wood film body 11 laminated acrylic panel is manufactured.
