Description

A process of floor board which makes intensity of the surface}

Efforts have been made to remove various harmful substances from the lumbers and boards used for flooring, but they are not effective.

Therefore, the method of manufacturing the surface-hardened flooring material of the present invention belongs to the field of making the surface-cured laminated (single layer) standard material after attaching the melamine resin sheet by making the compressive strength much stronger than the physical properties of the original wood, and making the flooring material processed by conventional solid wood. The surface layer is finished with a coating method using a urethane-based or UV paint to make a finished product.

On the other hand, the present invention, after processing the wood to the flooring material specifications

Press the thermosetting resin sheet onto the surface with much stronger surface strength

It belongs to the field of making finished products of surface hardening flooring.

When the surface hardening flooring is made of conventional plates or lumbers, the surface layer hardened resin plate is whitened or easily cracked or broken due to high elasticity or low surface strength due to low density.

  In addition, when processing the solid wood into a flooring material, it is necessary to apply the coating after the flooring construction because of the high elasticity or the surface is not strong due to the low density and water content of the surface.

The surface of the finished flooring is easily scratched, pressed, etc.

Not only are they unsightly due to marks and cracks, but their service life (3-4 years) is very

It is short and the surface is very monotonous, and there is a lot of warpage due to moisture absorption.

It became.

The problem of the present invention surface hardening flooring manufacturing method is made by processing the conventional solid wood

In the case of flooring material, the surface layer finish is mainly paint.

Scratches or crushes cause ugly marks and cracks

Due to its very short shelf life, it is not possible to increase the durability and

Can emboss on the surface to enhance the beautiful texture of the flooring.

In addition, moisture is also blocked to prevent warpage of flooring material.

The problem of the method of manufacturing the surface hardening flooring material of the present invention is to prevent the occurrence of the whitening of the surface easily due to being taken or pressed after construction of the finished flooring material, or to prevent cracking or cracking, as well as rising from the floor. In order to prevent the warping caused by the coming moisture.

The problem solving means of the method of manufacturing the surface-hardened flooring material of the present invention is to increase the compressive strength much more strongly than the physical properties of the original wood through the pressing step after drying at high temperature, and then attach the thermosetting sheet (melamine resin) and heat-press the surface first. It is also made of "standard material" of flooring material. In addition, the flooring material may be completed by hot-pressing a resin-impregnated balance sheet to the flooring material to prevent warping and moisture of the finished flooring material.

The problem solving means of the method of manufacturing the surface-hardened flooring material is wood flooring

"Standard materials" (including boards, angles, aggregates and aggregates) processed into shapes

In the high-temperature dryer, the method of drying and pressing by the press

After increasing the compressive strength of the surface much more than the properties of the wood,

A thermosetting resin sheet containing a wear resistant material is attached, and the surface is secondarily heated to make a surface hardened "standard material". At this time, insert a special heat resistant sheet with embossing between the surface resin sheet and the hot plate of the press.

Patterned texture can be completed with very beautiful flooring.

 In the manufacturing method of the surface-hardened flooring material of the present invention, the surface-cured laminated standard material is a six-step manufacturing process, and the surface-cured monolayer standard material is made through a three-step manufacturing process.

First step: high temperature drying step

Thinly cut solid wood or lumber with a blade, and dry wood or lumber with a saw.

Dry board, laminated board with aggregated board, angled board and house with laminated board

The material which processed the timber etc. to the standard of flooring material (hereinafter called "standard material")

Put it in the high temperature dryer at 90 ~ 130 ℃ and dry it for about 10 ~ 20 minutes.

2nd step: Crimping step

Place the finished “standard material” into the press and place both surfaces about 15-35kg / cm ²

 Pressurized to reduce the volume and instead increase the density per unit volume.

 The compressive strength is much stronger than that of the wood.

Third Step: First Adhesion Step

In the case of the "standard material", which has such high strength, a thermosetting sheet (melamine-based, urethane-based, Polysiloxane-Amine, Acrylic

We attach system) and make surface thermosetting resin board

In case of each of the standard materials, attach a thermosetting sheet containing wear-resistant materials such as aluminum oxide (ceramic, silica, etc.) to the upper surface, and at the same time apply a thermosetting sheet (melamine resin) (to prevent moisture on the bottom of the flooring material). Attach.

Fourth Step: Primary Heat Pressing Step

The "standard material" ( in case of plate), which is attached with a thermosetting sheet on the back surface of the surface of the first bonding step, is again heated to a heating plate temperature of 100-130 ° C, and the pressure is about 15-35kg / cm ² and The time is about 1 to 3 minutes to press the surface of the "standard" first.

If specification of the timber material is the primary bonding step is finished dimension lumber back to 100 ~ 130 ℃ a heating plate temperature of the heat accumulator, the pressure is about 15-35kg / cm ² And the time is about 1-3 minutes

The surface of the "standard material" is first pressurized.

At this time, if necessary, special heat resistant sheet embossed to form a pattern on the surface of the flooring material. It can be placed between hot press plates.

5th step: 2nd adhesion step

In the case of the standard material to which the thermosetting resin plate is attached, the plate of materials such as plywood, wood fiber board, thick wood veneer board, and PVC board is bonded again with a thermosetting or thermoplastic adhesive, and a thermosetting sheet (melamine-based resin) Attach.

In the case of using the thermosetting adhesive in the secondary bonding step, the heating plate temperature of the thermocompressor is 100-130 ° C., the pressure is about 15-35kg / cm ² and the time is about 1 to 3 minutes.

Secondly pressurize the surface of the "standard material",

 In case of using a cold press adhesive, it is pressed by a cold press (Cold Press) and adhered.

After the second heat press step or the second cold press step

It is made of a surface hardened laminate standard material (see Example 4).

6th step: 2nd Heat Pressing Step

After completing the secondary bonding step, the standard material (plate) was again heated to a temperature of 100 to 130 ° C., and the pressure was about 15 to 35 kg / cm ^2. And the time is about 1 to 3 minutes to pressurize the surface of the "standard material" secondary.

In the case of using the thermosetting adhesive in the secondary bonding step, the temperature of the heating plate of the thermocompressor is 100 to 130 ° C., the pressure is about 15-35kg / cm ² and the time is about 1 to 3 minutes.

Secondly pressurize the surface of the "standard material",

 In the case of using a cold press adhesive, it is pressed by a cold press (Cold Press) and adhere | attached.

Through the second heat press step or the second cold press step

It is made of a surface hardened laminated standard material (see Example 5-1).

In the case of each material, in the case of one of the material or aggregate wood among the standard materials made through the pressing step (2), the surface of the wear material of aluminum oxide, ceramic, silica-based wear resistant material is contained on one surface. Surface-hardened single-layer standard material (Example 5-) through the first heat press step (14) to heat the first through the first adhesive step (13) of attaching the thermosetting sheet and a thermosetting sheet (melamine resin) on the back 2), each of which is processed into the shape of the floor covering for grooves, tongues, and joints at the four edges of the surface-hardened single-layer or laminated "standard" mentioned above, and then the surface-hardened single-floor (flooring) or surface A finished product of a cured laminated flooring (flooring) is made (see Examples 6-1 and 6-2). Therefore, in the case of the conventional flooring material which has finished the surface by painting solid wood, the elasticity or surface strength is not strong due to the high moisture content and low density of the surface layer, so that cracks are easily cracked even by slight scratches and presses. Although the life is short due to the occurrence or cracking, the present invention not only makes the surface material last much longer by curing the surface,

In the case of the surface-hardened single-layer standard material as in Example 4 above, by inserting various patterns on the surface using a special heat-resistant sheet with embossing before the first heat pressing step, In addition, a thermosetting sheet (melamine resin) is also attached to the back surface to prevent warpage due to moisture absorption.
