DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for processing a linoleum material, and more particularly to a method for processing a linoleum material using a jute or the like as a carrier.

[0002]

2. Description of the Related Art Linoleum, a natural fiber, is obtained by synthesizing linseed oil, natural resin (pine resin), pigments, wood chips, cork and the like made from the seeds of flax plant, and using the synthesized material as a jute as a carrier. It is manufactured by pressing. The manufactured linoleum material is distributed in the market in a long shape of, for example, 10 m to 30 m which is wound in a roll shape with a width of 2 m.

[0003] In ordinary floor construction, after unrolling the rolled product at the construction site, temporarily laying it down for several days, allowing it to adjust to the floor surface, and then using an epoxy adhesive having a relatively strong adhesive force. To stick to the floor.

However, since the linoleum material uses the jute on the back surface as a carrier, the jute expands and contracts due to moisture and heat, and after construction, inconveniences such as swelling and raising due to the expansion and contraction tend to occur. In addition, since it is packed in a roll shape, it is difficult to completely remove the curl in the winding direction, and therefore, a kamaboko-shaped swelling occurs after construction.

[0005] From the above, when the linoleum material is cut into a shape that is easy to construct, for example, a 900 mm square or 600 mm square or the like shape similar to a PVC tile, the dimensional accuracy is deviated. For this reason, in some cases, instead of jute, a method of pressing a glass fiber sheet in a production process has also begun, but in this case, since the linoleum material cannot be wound in a roll shape and becomes a plate shape, Due to the significant changes in the production process, it is currently not a common method and is used only for the processing of very small 500 mm square tiles. In addition, when the linoleum material is to be installed in a long form, the linoleum long sheet is cut and attached on both ears at the site, but in this case, some deformation or lifting is inevitable. .

[0006]

Therefore, a linoleum material using the above-mentioned jute or the like as a carrier can be converted into a fixed-size material (1800) in consideration of portability, design and workability.
mm square, 1200 mm square, 900 mm square, 600 mm square, 450
In manufacturing a long material having a square width, a square length of 300 mm, a square length of 250 mm, etc.) or a fixed width, it has been an issue to minimize the expansion and contraction and curl of the material. This is the same in the case of pasting a design composed of a complicated inlaid or parquet style.

[0007] With the recent spread of floor heating, even when a linoleum material is used as a living floor material, it is necessary to prevent deformation due to the influence of heat.

Further, the characteristics (load resistance, antibacterial property, walking feeling, antistatic property, etc.) of the linoleum material, which is a natural material, are reviewed, and it is desired to expand its use range.

[0009]

In order to solve the above-mentioned problems, in the present invention, a part or all of the linoleum material having a thread-like carrier is removed, and a shape-stabilizing member is joined to the removed portion. Then, a plate-shaped or sheet-shaped member is bonded thereon. The shape stabilizing member is a member that suppresses deformation of the linoleum material, and may be any material that is not easily changed by water, heat, or the like.

[0010] By using the shape-stabilizing member, the dimensional stability of the linoleum material can be improved.

Further, by appropriately setting the material and thickness of the plate-shaped or sheet-shaped member, a new effect can be added, and the range of use of the linoleum material can be greatly expanded. For example, by appropriately setting the thickness of the plate-like or sheet-like member, it is possible to improve walking feeling and heat retaining effect, and to improve the antistatic effect by using a conductive plate-like or sheet-like member. Can be.
Furthermore, if a porous plate-like or sheet-like member such as cork is used, a floor material having a high soundproofing effect can be obtained, and the value of the linoleum material can be further increased, and its use range can be expanded.

[0012]

The ultrasonic planer 87 as described above is fixed so as to cross the linoleum material 10, and the blade 87c is fixed to the linoleum material 1 as shown in FIG.
By tilting the linoleum material 10 in the direction of the arrow, a part or all of the jute yarn on the surface is removed.

FIG. 6A is a sectional view of the linoleum material 10 including the jute thread 10a. When the jute thread 10a is cut, a part of the jute thread 10a may be cut off, or the whole may be cut off. FIG. 6 (B) shows an example in which a part (upper half) of the jute yarn is shaved, and FIG. 6 (C) shows an example in which the jute yarn 10a is entirely shaved. In the case of FIG. 6B, the linoleum material 1
The surface of No. 0 is not shaved, but in the case of (C), a part of the surface is shaved together with the jute yarn 10. The more jute yarns 10a are removed, the smaller the effect of the jute yarns can be.

Next, a method of sizing the linoleum material from which the jute yarn has been removed as described above will be described. Linoleum material generally produced is 2.0mm, 2.5m
m, 3.2mm thick, 2000mm wide, 10m long
30 m, supplied in roll form. As a carrier, a jute thread of about 0.5 to 0.8 mm is 2-3.
It is woven in a lattice of mm. A method of manufacturing a fixed-size flooring material of 900 mm square or the like using this type of linoleum material will be described.

First, a part or all of the jute yarn is removed by the method described above (step 601), and then the pre-cut is performed (step 602). In preliminary cutting, for example, 12
Cut to a length of about 00mm. Then, using a coating machine,
Apply an adhesive to the jute yarn surface (step 603),
A shape stabilizing member is attached (step 604). The adhesive may be applied to the shape-stabilizing member in advance.

As the shape stabilizing member, a member formed by weaving glass fibers vertically and horizontally can be used. Thereby, expansion and contraction in the vertical direction and the horizontal direction are suppressed, and the shape stability is high. More specifically, for example, a long fiber reinforced thermoplastic resin composite material “Preglon” (trade name) manufactured by Mitsui Chemicals, Inc. is used as the shape stabilizing member. "Preglon" is a new sheet-like material in which glass fibers are arranged in one direction or orthogonally and polypropylene resin is contained in the glass fibers. By lining such a material, it becomes a flexible and extremely resistant (non-expandable) floor material to moisture, water, and heat. It becomes a floor material that can be used even under bad conditions.

Next, a polyester non-woven fabric as a plate-like or sheet-like member is bonded with an adhesive or the like (step 605).

Thereafter, the linoleum material, the shape-stable member, and the plate or sheet member are pressed (step 60).
6), refining and curing (step 607). For example, it is stored in a multi-stage dry insulated storage and stored at a predetermined temperature for a predetermined time. Next, it is cut into a fixed size using an ultrasonic cutter or the like (step 608), and finally packed and shipped (step 609).

As shown in the sectional view of FIG. 8, the completed floor material has a three-layer structure of a linoleum material 1 from which jute yarn has been removed, a glass fiber material 3, and a polyester nonwoven fabric 5.

According to the above-mentioned method, since part or all of the jute yarn is removed from the linoleum material and the shape stabilizing member is joined, expansion and contraction by the jute yarn can be eliminated.
Therefore, a linoleum material having dimensional stability can be provided.

Further, by joining the plate-like or sheet-like members, it becomes a linoleum material which can be more easily used.
For example, by using a thick polyester nonwoven fabric 5 as a plate-like or sheet-like member as shown in FIG. 8, a floor material suitable as a tile to be laid can be obtained. Further, since a thick plate-like or sheet-like member is used, the walking feeling is good, and since it is not thermally deformed and has a high heat retention, it is suitable as a floor material used for floor heating or the like. Note that a weak adhesive may be applied to the lower surface of the nonwoven fabric 3 of the flooring material in FIG.

If a conductive sheet (a plate material or a sheet material containing carbon fibers) is used as the plate-like or sheet-like member, it is possible to provide a flooring material having a high antistatic effect.
FIG. 9 shows an example thereof. This flooring is formed by joining a linoleum material 1 from which jute yarn has been removed, a glass fiber material 7, and a conductive sheet 9 containing carbon fibers. As shown in FIG. 11, openings 7a are formed at appropriate intervals in the glass fiber material 7 as a shape stabilizing member, and the linoleum material 1 and the conductive sheet 9 come into contact with each other through the openings 7a. The charged static electricity is discharged through the conductive sheet 9.

In recent years, an OA having a raised floor made of a metal plate or the like has been developed.
A compatible double floor is known, but a floor material having a high antistatic effect as shown in FIG. 9 is suitable for laying on such a metal floor.

FIGS. 11 and 12 show a second embodiment of the present invention. In this example, a fixed-size long sheet (for example, 1800 mm) is used.
× 9 m). Linoleum material 1
1 instead of removing the entire jute thread,
a and the jute yarn of the intermediate portion 11b alone are removed, and the glass fiber material 13 which is a shape stabilizing member is joined to that portion. A portion of the gas fiber material 13 and the linoleum material 11 from which the jute yarn has not been removed is bonded to the polyester nonwoven fabric 5 as in the example of FIG.

According to the above, since the linoleum material is prevented from expanding and contracting at the end portion and the intermediate portion of the linoleum material 11, the overall dimensional stability is improved. Furthermore, the time for the jute removing step and the step of attaching the shape stabilizing member can be shortened, and the amount of the shape stabilizing member used can be reduced, so that a low-cost floor material can be provided.

FIG. 13 shows a third embodiment of the present invention.
This example shows an example of processing a linoleum long sheet as a long roll.

In FIG. 13, first, a part or all of the jute yarn is removed by the method already described (step 70).
1) Then, using a coating machine, an adhesive is applied to the jute yarn surface (step 702), and a shape stabilizing member is attached (step 703). The adhesive may be applied to the shape-stabilizing member in advance. The shape stabilizing member is the same as in the example of FIG.

Next, a polyester nonwoven fabric as a plate-like or sheet-like member is bonded with an adhesive or the like (step 7).
04), the linoleum material, the shape-stabilizing member, and the plate-shaped or sheet-shaped member are joined by a heat roll press (Step 705), and the material is tempered and cured (Step 706). For example, it is stored in a multi-stage dry insulated storage and stored at a predetermined temperature for a predetermined time. Next, the linoleum material was sized (1800m
m, 1200mm, etc.) and drop your ears (Step 7)
07), rewind it into a roll and pack it again (step 7)
08).

As the plate-like or sheet-like member, other natural materials such as cork, natural rubber, conductive carbon sheet, metal plate, styrene board, fiber board and the like or a combination thereof can be used. When used, a warming effect, a soundproofing effect, an antistatic effect, a good walking feeling, etc. can be obtained according to the characteristics of each material.

Further, the plate-like or sheet-like member may be constituted by a multilayer as required. For example, a plate-shaped non-woven fabric impregnated with acrylic may be sandwiched between glass fiber sheets and a cork material may be bonded to a lower portion thereof, so that strength, dimensional accuracy, heat insulation effect, and sound insulation effect are further enhanced. The effect is obtained.

The linoleum material from which the jute has been removed is bent into an L shape, a metal plate (aluminum, copper, etc.) previously processed into an L shape is bonded to the bent portion, and a shape stabilizing member is laminated from the back surface. Thus, it is also possible to produce an L-shaped linoleum material. This can be achieved by using an L-shaped skirting board (folded skirting board) at the joint surface between the floor and the wall of a hospital or the like where you want to prevent the occurrence of various bacteria, so that the boundary between the wall and the floor is seamless. Can be very effective. The shape stabilizing member may be joined between the linoleum material and the metal plate.

[0038]

As described above, according to the present invention,
Since part or all of the linoleum material having the thread-shaped carrier is removed and the shape stabilizing member is joined, deformation of the linoleum material can be prevented. Further, since the plate-like or sheet-like members are joined, a linoleum material having higher added value can be provided.
