Description

Two Fold Floor Material and Manufacturing Method Thereof}

TECHNICAL FIELD The present invention relates to a double floor and a method of manufacturing the same, and more particularly, to a double floor using a conductive or non-conductive tile and a combination wood as a material and a method of manufacturing the same.

As is well known, a double floor material (ACCESS FLOOR) designed to secure a space for wiring by constructing another floor on the floor of the building is conventionally utilized.

Systemization of wiring leads to a pleasant office environment and secures safety and flexibility of wiring. These floors can be divided into ACCESS FLOOR and OA FLOOR.

The access floor is used for large-scale wiring, floor air conditioning facilities and drainage facilities, and is applied to soundproof dustproof facilities, special facilities, and large facilities. The finishing materials are mainly composed of antistatic tiles and conductive tiles.

In addition, the office floor is mainly used in general offices or renovated buildings with low load and low wiring capacity, and finishes are mainly performed with carpet tiles.

Looking at the structure of such a double flooring as shown in Figure 1 conductive or non-conductive tile (100) below the conductive or non-conductive tile (100) to produce wood from the wood and finely crush the remaining pieces, and between Sprinkle the adhesive to a high temperature and pressure to adhere to the particle board 101 made of a plate-like shape, it is made by adhering the blocking material 102 such as aluminum foil on the bottom.

Such a conventional flooring material can be obtained by the particle board 101 has a high sound absorption, excellent thermal insulation effect, can be produced a plate of a large area, but when the pressure is applied locally, the particle board 101 Is difficult to ensure durability by

In addition, when moisture penetrates the particle board 101, swelling occurs, and thus, there is a problem such that it is difficult to bend and maintain the flatness of the bottom surface, which shortens its lifespan and thus requires periodic reconstruction. There is a problem.

It is an object of the present invention to provide a lightweight double flooring and a method of manufacturing the same as well as reinforcing the pressure and water resistance of the flooring to solve such problems.

The object of the present invention is to be formed alternately between the single layer (조합) layer and the combination wood layer below the conductive or non-conductive tile, and to place a shielding material such as aluminum thin plate beneath it, between the flame retardant such as melamine resin The present invention proposes a double bottom material formed by applying a thermosetting resin and then molded by a hot press and a method of manufacturing the same.

Accordingly, the present invention is hardly deformed or damaged even in the movement of heavy materials, and has an effect of providing a durable flooring material having excellent water resistance.

Referring to the present invention in more detail with reference to the accompanying drawings as follows.

In the well-known thing provided with the aluminum thin plate etc. used as the conductive tile or the non-conductive tile 1, and the barrier material 2, it is a several single plate layer 3 of 1 mm-3 mm thickness, and is 10 mm-20 mm thickness. Prepare a plurality of block boards (4) (Block Board) and superimpose them, and spread the flame retardant thermosetting resins such as melamine resin for adhesion to their contact surfaces on both sides or in a cross section of 200g / m ² to 350g / m ^2. spread evenly with a spreader), and compress them with a thermopress press, compressing them for 20 minutes to 30 minutes at a pressure of 8 Kg / cm ² to 15 Kg / cm ² at a temperature of 110 ° C. to 150 ° C. to obtain a wood plywood, and the electric tile (1) And adhesive between the barrier material 2.

In this way, the present invention is that the flame retardant thermosetting resin such as melamine resin is hardened in the state of penetration into the end plate layer (3) and the block board (4) by high pressure and high heat during the thermocompression bonding process. This is excellent.

When the present invention will be described in detail by specific embodiments as follows.

Example 1

In the present embodiment, first, two 2 mm thick single plate layers 3 are used as the surface layer and the middle layer, and a block board 4 (Block Board) having a thickness of 12 mm is placed below the 1.2 mm thick single plate layer (3). 1 layer is arranged in the middle layer, and a block board 4 having a thickness of 12 mm is disposed below it, and a single plate layer 3 having two thicknesses of 2.0 mm is disposed below it, and a melamine resin is applied to the contact surfaces thereof. Spread it evenly with a spreader to 250g / m ² , and compress them by a hot press, it was completed by pressing for 25 minutes at a pressure of 9Kg / cm ² at a temperature of 130 ℃ bar double floor according to the present invention is domestic As a result of the pressure test, a bending rate of 2 mm was measured at a load of 500 Kg / f, and the compression fracture test resulted in excellent results of more than 1500 Kg / f. The water resistance test resulted in a good result without deformation.

Example 2

In this embodiment, first, two 1.2 mm thick single plate layers 3 are used as the surface layer and the middle layer, and a block board 4 (Block Board) having a thickness of 13 mm is placed below the 2.0 mm thick single plate layer ( 3) Arrange one layer in a middle layer, and place a block board 4 having a thickness of 13.0 mm below the bottom and a single plate layer 3 having a thickness of 7 mm below the bottom, and apply a melamine resin to the contact surfaces thereof. Spread evenly with a spreader (spreader) to be / m ² , and compress them by a hot press, which was completed by pressing for 30 minutes at a pressure of 8Kg / cm ² at a temperature of 130 ℃ bar double floor according to the present invention is pressure-resistant As a result of the test, the bending rate of 2mm was measured at the load of 500Kg / f. The compression failure test resulted in excellent results of more than 1500Kg / f, and the water resistance test resulted in no deformation at all.
