Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to improvements in the structure of flooring materials used for flooring and the like, and in the method of using the same.

[Conventional technology]

A flooring material made by pasting broad-leaved 8i'8 precious wood on a base plate made of plywood is widely used because it is aesthetically pleasing and more hygienic than carpets. By the way, since decorative boards made of precious woods such as hardwoods are expensive, it has been customary to use ones that are as thin as possible.

However, as with other building materials, C
There is a growing demand for flooring materials with thicker precious wood than 1. As a result, there are now more and more products that use broad medium-sized precious wood that is about three times as thick as the conventional one, that is, about 1 mm or more thick.

[Problems to be Solved by the Invention] However, since precious wood with a thickness of about 11fl1 or more is used, it is not only expensive as a material, but also has various problems as described below.

First, when using a thick precious wood of 1 layer or more, it is essential to dry the precious wood prior to bonding, which is complicated and requires manual drying. When a comparatively thin decorative board of 0.5 mm or less was used as in the past, there was no need to dry it prior to lamination. Therefore, when a decorative board made of precious wood with a thickness of 1 mm or more is used, there is a problem that it is not only expensive as a material, but also has poor workability, making it more expensive.

Secondly, when a thick decorative board of 1111ff1 or more is used, there is a problem that cracks and cracks are likely to occur on the surface. In other words, in the case of conventional thin decorative boards, they can be used in an undried state and are sufficiently pliable.
Therefore, defects such as cracks were less likely to occur after bonding, but if a decorative board with a thickness of 11B111 or more is used, it cannot be bonded except for a drying process, so warping and distortion inevitably occur. Therefore, cracks may occur during pasting, and even poor quality of pasting may occur.
] Cracks and cracks often occurred during use.

Therefore, the object of the present invention is to provide not only an excellent external vAn and texture similar to the case of using a decorative board made of thick precious wood of 1 m111 or more, but also a material that is resistant to cracking and cracking and has excellent quality stability. Our goal is to provide affordable flooring materials.

[Means for Solving the Problems] The flooring material of the present invention includes a base plate and at least 3 layers of decorative boards made of precious wood and pasted in 81 layers in one direction on the base plate. In addition, in the manufacturing method of the present invention, after a first decorative board made of precious wood is pasted on a base plate, a decorative board made of n −2 (n is a natural number of 3 or more) pieces of precious wood impregnated with an adhesive is provided. It is characterized by the process of pressing the outermost layer of decorative wood, which is made of precious wood, after being polished.

[Operations and Effects of the Invention] In the floor material of the present invention, at least three layers of decorative boards made of precious wood are pasted on the base plate.

Therefore, by using a thin decorative board made of precious wood that can be removed in an undried state, it is possible to give the same aesthetic appearance and texture as when using one or more thick layers of precious wood decorative board. can. In addition, when handling a decorative board in an undried state (when using a decorative board with a thickness of Therefore, a floor material with better quality can be obtained.

Furthermore, compared to using a single thick decorative wood board,
Since it uses at least three layers of decorative board, if the overall thickness of the decorative board part is the same, it is possible to use a thinner decorative board, making it cheaper in terms of materials. . In addition, when a decorative board with a thickness that can be handled in an undried state is used, it is not necessary to carry out a drying process, so a floor material that is even more inexpensive can be obtained.

Furthermore, among the three or more decorative laminates, only the outermost decorative laminate is made of high-quality precious wood decorative laminate, and the precious wood decorative laminate sandwiched between the base plate and the base plate on the inside is not so high quality. Since the appearance and texture will not deteriorate even if a non-existing material is used, it is also possible to construct an even cheaper floor material.

On the other hand, 3 or higher decorative boards are bonded together using adhesives, so they are stronger and more durable than a single thick decorative wood board. can be obtained.

In addition, with the manufacturing method of the present invention, not only can a floor material having various effects as described above be obtained, but also when a decorative board having a thickness that can be handled in an undried state is used,
It is possible to manufacture the floor material without performing the drying process, thereby dramatically improving the workability in manufacturing the floor material.

[Example: J2 Akira] A manufacturing method according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4. First, as shown in Figure 2, for example, 9
A precious wood decorative board 2 having a thickness that can be handled in an undried state is pasted onto a base plate 1 made of plywood with a size of 00x1800x12 to 15ffiI11.

In this case, as the precious wood decorative board 2, a low-quality one whose appearance is not so good can be used.

In addition, when using a decorative wood board 2 having a thickness that can be handled in an undried state, for example, when Hiro TfX84 Yamarai is used, the thickness is about 0.5 mm or less, more preferably about 0°3 m11.

Next, as shown in Figure 3, cut and divide into pieces with a width of 60 to 4
00g111 base plates 1a, 1b, 1C and precious wood decorative boards 2a, 2b, 2c are obtained. Next, as shown in Figure 4,
A second decorative wood laminate 3 impregnated with an adhesive such as vinyl acetate, urea, or melamine and a third decorative wood laminate 4 serving as the outermost layer are pasted onto the decorative wood laminate 1a.

This bonding is carried out by overlapping the second decorative wood laminate 3 and the outermost decorative wood laminate 4 and then heat-pressing them from above.

Similarly to the precious wood decorative board 1, the second decorative wood laminate 3 and the outermost decorative wood laminate 4 are handled in an undried state.
, made of broad-leaved precious wood with a thickness of 5 a+m or less. Further, as for the second decorative wood veneer 2, a low-quality one whose appearance is not so good is used like the first decorative laminate 2 made of precious wood. be able to. However, since the third precious wood decorative board 4 located at the outermost layer is exposed on the surface, it is necessary to use a high quality board with excellent appearance.

It is preferable that the fiber directions of the first and second decorative wood laminates 28.3 are aligned in the same direction as the decorative wood laminate 4 of the outermost layer, as shown in FIG. Even if the outermost layer of decorative wood veneer 4 is worn down during use,
Since the pattern of the inner decorative wood decorative boards 2a and 3 is the same as that of the outermost decorative wood decorative board 4, the original appearance is maintained throughout the long period.

As described above, the flooring material 10 shown in FIG. Therefore, there is no need to carry out the complicated and artificial drying process that is required when using conventional precious wood decorative boards with a thickness of 111III1 or more.In addition, there is no need to carry out the complicated and artificial drying process that is required when using a conventional decorative wood board with a thickness of 111III1 or more. It is also possible to prevent the occurrence of

In addition, since the second precious wood decorative board 3 is impregnated with resin in advance,
It is reinforced with resin, so it is made of precious wood.
It can be seen that the strength of the laminated structure of i2...4 is much higher than that of a single decorative wood board of the same thickness, and therefore the floor material has excellent abrasion resistance J3 and impact resistance.

The number of laminated layers of each decorative wood laminate may be four or more, so that a thin decorative wood laminate that is inexpensive and does not require a drying process can be used to create a floor material with a thicker decorative wood laminate and a superior quality feel. can be manufactured.

Further, in the above embodiment, a 900x1800 base plate is used for manufacturing, but base plates of other sizes may be used. Furthermore, it is not necessarily necessary to divide the plywood, and 8!1 layers of precious wood decorative boards may be applied while keeping the base plate of the original size.

In addition, the thickness of each decorative wood board is preferably one that can be handled in an undried state, but this thickness varies depending on the type of tree used as material and is not uniquely determined. . Therefore, the above 0,
The thickness of 5u+ or less is merely an exemplary value for the case where a decorative wood board derived from ordinary hardwood is used.

Roughly speaking, in the above embodiment, the first and second decorative wood veneers 2.3 located on the inside are made of low-quality decorative wood laminates, but the same material as the decorative wood laminate 4 located on the outermost layer may be used. Needless to say, it may be used.

J3, as the base plate 1, it is also possible to use veneer in addition to plywood.

It should be pointed out that this invention is most suitable for constructing a so-called colored floor, in which the exposed precious wood decorative board is painted with a highly abrasion-resistant colored coating.
