Description

Description: TECHNICAL FIELD The present invention relates to a floor panel, particularly a floor panel suitable for a room in which office equipment is installed.

(Prior Art and its Problems) Conventionally known methods of bonding a tile carpet to a double floor have been widely used.

In this case, a method of bonding with an adhesive or a method of fixing with an adhesive is adopted.

However, in these methods, there are cases where the tile carpet is fixed on the double floor in advance at the factory and then carried in the field, and cases where the tile carpet is fixed on the double floor after loading, the final finishing to fix the tile carpet on the double floor In addition to the low efficiency at the stage, it was very inconvenient when only the tile carpet was peeled off and washed and reused (off-location cleaning).

(Means for Solving the Problems) In the present application, the tile carpet can be easily fixed to the floor panel surface, there is no trouble such as peeling during walking, and the floor panel body and the tile can be easily formed in the case of off-location cleaning. A floor panel that can be reused by peeling a carpet, and a tile in which a flexible continuous foam resin non-slip layer is provided on the entire back surface of a synthetic resin backing material on the surface plate of a small rectangular or square panel piece having legs at four corners The gist of the present invention is a floor panel characterized in that a carpet is suction-fixed in a state of being in close contact with the carpet.

 Hereinafter, the present invention will be described with reference to the drawings.

FIG. 1 is an enlarged view of the back surface portion of the floor panel of the present invention, wherein 1 is a small panel piece and 2 is a leg. The small panel piece 1 and the leg 2 are integrally formed of a synthetic resin such as ABS resin, hard PVC resin (PVC), or polypropylene.

The small panel piece 1 has a rectangular or square shape with a side of 10 to 50 cm, and has leg portions 2 each having a quadrant-shaped cross section at four corners.

The small panel piece 1 configured as described above is completely separated, and these sides are continuously connected 3 in front, rear, left and right to form a unit assembly 4, thereby forming the floor panel base body of the present invention. Is done.

FIG. 2 is a rear view of the floor panel of the present invention, one side of which is shown.
It is a rectangle or a square of 10 to 50 cm, and a space A is obtained between the broken lines a and a ', and a space B is obtained between the broken lines b and b'. Reinforcing legs may be added in the small panel pieces so as not to hinder cord storage.

The power cord led to the office equipment is freely passed through the space defined by the floor base, the legs 2 and the panel pieces 1. A hole for drawing out a power cord is formed in the floor panel in advance or at the time of construction.

If the small panel piece 1 and the leg 2 are tapered and the tip of the leg is slightly narrowed, it is easily deformed, and the absorption of unevenness of the floor substrate is improved.

FIG. 3 is a cross-sectional view of the floor panel of the present invention, 2 is a leg portion of the floor panel, and 5 is a surface plate of a small panel piece. A tile carpet 9 on which a pile 6 and a synthetic resin backing material such as PVC, EVA, polyurethane, or synthetic rubber are laminated is laminated on the surface plate.

In the tile carpet, one to three layers of a fibrous base material 8 such as a woven or nonwoven fabric are interposed.

An anti-slip layer 10 made of a flexible continuous foam is formed on the floor panel fixing surface (back surface) of the tile carpet backing material.

Examples of the resin used for the anti-slip layer include PVC homopolymer, vinyl chloride-vinyl acetate copolymer and PVC-E
In addition to a mixture of VA, acrylic resin, and polyethylene, an emulsion-type continuous foam made of polyurethane, a mixture of polyurethane and an acrylic resin or a diene rubber is preferable. These foams have a continuous foamed resin surface with micropores.

In the present invention, a flat continuous foamed resin surface having fine holes means a structure in which fine holes are almost uniformly distributed when holes are formed in a resin film.

Urethane resin is not particularly limited, polyether polyols, polyester polyols, and high molecular weight polyols such as other polymer polyols, aromatic polyisocyanates, polyisocyanates such as resin polyisocyanates and alicyclic polyisocyanates and If necessary, it can be prepared by using known components such as other reaction components and additives.

Next, an outline of an example of a method for producing an emulsion by a mechanical foaming method will be described.

If necessary, add a foaming agent, foam stabilizer, viscosity adjuster, crosslinking agent, colorant, filler, antioxidant, antifungal agent, preservative or other additives to the above emulsion, and use a machine such as an Oaks mixer. It is mixed with air in a foaming machine to prepare a foamed emulsion containing bubbles.

The anti-slip layer of the present invention can be obtained by applying the emulsion to the back surface of the backing material and drying or laminating a continuous foam sheet formed in advance.

Known foam stabilizers can be used, and silicone foam stabilizers are preferably used.

In the present invention, only by pressing the tile carpet onto the small panel piece surface plate from above, the foam is in a state of being sucked in close contact with the small panel piece surface plate, and the tile carpet is not easily peeled off during walking. used.

4 and 5 are partially enlarged views of FIG. 3, in which reference numeral 7 denotes a backing material of a tile carpet, and reference numeral 5 denotes a surface plate of a small panel piece.

A large number of open cells 11 are present in the open cell layer 10, and when the open cell layer 10 is pressurized from above the tile carpet with a pressure P, the open cells are crushed as shown in FIG. Is deformed as shown in FIG.

At this time, a suction function is generated, and the backing material and the small panel piece surface plate adhere to each other, the non-slip property is given to the back surface of the tile carpet, and the tile carpet does not slip. The tile carpet can be peeled off without any difficulty if it needs to be removed.

Thus, the floor panel of the present invention is obtained, and a double floor can be easily formed by laying the floor panel.

When attaching tile carpets of different types and colors on the floor panel according to the user's request, a lot of room was required for the delivery date, but the present invention responds to the user's request as quickly as possible. it can.

The tile carpet of the present invention may be fixed on the floor panel surface plate even in the case of a floor panel in which the legs are separated from the surface plate such as calcium silicate.

(Function) The tile carpet and the small panel pieces adhere to each other by pressing the soft continuous foam layer to crush the foam.

The mechanism by which the continuous foamed layer of the present invention develops the adhesion to the small panel piece surface plate is not due to adhesiveness, but is due to the fine grooves in the surface layer and the internal cell structure and the moderate elasticity of the constituent resin.

This is a completely different method from the conventional fixing method using an adhesive or a pressure-sensitive adhesive.

The foamed sheet of the present invention can be brought into close contact with the surface of the floor panel, and when the sheet is peeled off thereafter, the surface can be restored without being stained.

(Example) Example 1 A prepolymer aqueous solution of polyoxypropylene glycol and methylene diisocyanate was stirred, and 16 hexamethylene diamine aqueous solution was added dropwise to obtain a polyurethane emulsion. Next, a composition having the following composition including the obtained emulsion was obtained.

Polyurethane emulsion 100 Calcium carbonate 20 Carboxymethyl cellulose 0.8 Silicone foam stabilizer 1.3 Units are parts by weight.

The compounded emulsion was foamed with a foaming machine to obtain a foamed emulsion at a volume ratio of emulsion / air = 1/3.

The emulsion was coated, preheated with a far-infrared heater for 1 minute, heated at 160 ° C., cooled, and wound up.

The obtained continuous foam sheet has uniform micropores of approximately 20 μm, is a substantially flat resin surface, and these micropores are continuous with internal bubbles, and the foam density is 0.3 g / cm ³ . there were.

The obtained continuous foam sheet is laminated to the surface of the backing material of a tile carpet with a side of 50 cm, which is backed with PVC, with a thickness of 0.5 mm, which is the same size as the surface plate, and the legs and the surface plate are integrally molded. It was crimped on a small ABS resin floor panel piece (east reflex tile) surface plate to obtain the floor panel of the present invention.

Even when actually walking on the floor surface on which the obtained floor panel was laid, the tile carpet did not peel off at all, and the tile carpet could be peeled off as necessary without soiling the floor surface.

Example 2 Instead of the anti-slip layer of Example 1, an emulsion having the following composition was foamed three times with an Oaks mixer.

PVC-polyvinyl acetate emulsion (15% vinyl acetate) 100 Carboxymethylcellulose 0.5 Silicon foam stabilizer 1 Unit is parts by weight.

0.6mm on the back of the tile carpet backing material
Apply in thickness, preheat for 1 minute with far infrared heater, 140 ℃
To obtain a non-slip layer having a thickness of 0.4 mm and a density of 0.3 g / m ³ .

The obtained tile carpet was pressure-bonded to a small-floor panel single-faced panel as in Example 1 to obtain a floor panel of the present invention. Even when the obtained floor panel was constructed in the same manner as in Example 1, the tile carpet did not peel off during use, and the tile carpet could be peeled off as needed without soiling the floor surface.

(Effect of the Invention) The tile carpet was easily fixed to the small panel piece surface plate.

Sticking by type or color of tile carpet was extremely efficient.

The tile carpet did not peel off during walking.

At the time of off-location cleaning, it was easily peeled off from the floor panel main body, and only the tile carpet could be cleaned, and could be fixed on the floor panel again.

The cords can be stored under the floor for safe walking, and the panel body is separated, so that tile carpets can be used in common and convenient for production.

It was possible to integrally form the small panel pieces, the surface plate and the legs, and it was obtained at low cost, and the laying work was easy.
