Description

Floorboard and its manufacturing method {FLOOR BOARD AND MANUFACTURING METHOD THEREOF}

The present invention relates to a method for producing a floorboard comprising a novel floorboard patterning method and a floorboard manufactured accordingly.

In general, floorboard (floor) refers to the material used in the living room floor of apartments, detached houses, or indoor floors of offices and schools. The demand for natural friendly wood is increasing. For this purpose, wood is used as the floorboard material, or floorboards in which a plywood that is capable of giving the atmosphere of the wood to the plywood is widely used.

As a method of manufacturing a floorboard using veneer, a method using plywood, a method using high pressure lamination, and the like are disclosed. However, in the method of manufacturing floorboards using plywood, a thin hardwood single plate having a thickness of 0.4 to 0.5 mm is glued onto a plate made of softwood or Namyang plywood, and coated to strengthen surface durability (ultraviolet coating, electron beam coating, ceramic coating, etc.). And post-treatment processes such as special treatment (plastic resin impregnation, etc.). Therefore, as the manufacturing process is made in multiple stages, the manufacturing cost and equipment burden increases, the surface is easily damaged, there is a problem that does not give a feeling of natural lumber enough.

On the other hand, the method of manufacturing the floorboards decorated with veneer using a high-pressure lamination method, the surface can be very strong by high pressure and long-term heat pressure, there is an advantage that the color of the wood can be expressed most clearly. However, the high pressure lamination method is a lamination step of hot pressing at 120-150 ℃, 60-75 bar, 30-120 minutes by interposing veneer between the wear-resistant melamine-impregnated paper and 3 to 5 phenol-impregnated papers, Since the lamination sheet formed by the lamination step is included in the two-step process of attaching the platelet, there is a problem of increasing the manufacturing cost according to the multi-step process, there is also a problem of increased environmental pollution by uncured phenol.

In addition, when natural veneer is used in the high-pressure lamination method, the voids and densities of the veneers themselves are different depending on the species, and thus many manufacturing difficulties are usually used.

Usually, in order to express the texture of wood on the floorboards, it is common to print and paint on the floorboards. As an example, a film with a printed pattern is attached to a plate material, which is relatively inexpensive such as MDF and veneer veneer, by heat. In addition to the pattern, there is an advantage that can be expressed in various forms of abstract pattern on the plate material. However, in this method, the pattern is not directly printed on the plate, but the printed film is adhered to the plate, so that the natural texture as in wood is not felt, and the texture of the melamine sheet is not so good that the wood feels when touched. It can't feel and gives a hard plastic feel.

In addition, conventionally, a wood surface such as solid wood or plywood is burned with a torch lamp, etc., so that it is easily burned or slowly burned according to the soft and strong parts of the wood to form valleys and hills, thereby forming an uneven pattern. The surface of the plywood or plate by forcing the surface of the plywood or plate using a pressing roller (emboss cylinder) embossed with a brush, or using an embossed pattern. Processing methods such as three-dimensional representation have been used.

However, if the uneven pattern is imprinted in the same manner as above without any treatment on the plywood, the color difference between the engraved and unengraved parts is not obvious in the rough subsequent process, polishing, coloring, painting process, etc. If only the engraved part is expressed in a different color, there is a lot of contamination on the unengraved part. In addition, the engraved pattern can not be vividly colored, the coating is peeled off easily when the coating process on the carbonized portion is easily peeled off.

In order to solve the above problems, the present invention includes a method of transparently coating the surface of the wood for floorboards, and then engraved intaglio pattern using an emboss cylinder engraved with a wooden pattern, floorboard manufacturing method The purpose is to provide.

The invention also aims to provide a floorboard made according to the method.

In order to achieve the above object,

In the manufacture of floorboards,

After the transparent coating on the surface of the wood for floorboards, using the embossed cylinder engraved with a wooden pattern comprising the step of engraving the intaglio pattern on the surface, it provides a method of manufacturing floorboards.

The present invention also provides a floorboard produced by the above production method.

The present invention can feel the embossing of the intaglio pattern in the touch by engraving the intaglio pattern on the surface of the floorboard wood treated with transparent coating, and by engraving the pattern on the painted surface intaglio plate and engraved pattern Differences from and can be made clear to the desired level, plate color is protected, and by engraving the pattern on the surface on which the coating film is formed, the intaglio pattern base is protected by the coating film to improve durability.

In addition, when coloring and painting on the intaglio patterned portion of the coating film can prevent the plate surface contamination can implement a beautiful pattern texture, and the manufacturing process is simple to reduce the manufacturing cost.

In addition, when the method of the present invention is used, a species of high density, but the pattern is not beautiful and does not use as a veneer (eg, high density Namyangjae) can also be used for veneer.

Figure 4 is a photograph showing the heat resistance test results for the floorboard prepared according to the method of the present invention.
Figure 5 is a photograph showing the heat resistance test results for the floorboard manufactured according to the prior art.

Method for producing a floorboard according to the present invention is characterized by protecting the surface of the board by transparently painting the wooden board before engraving the intaglio pattern using the embossed cylinder in order to effectively express the pattern of the floorboard.

The method for producing the floorboard to which the present invention can be applied can be any method that is practiced in the art.

In general, if the surface of the floorboard wood is colored without any pre-treatment to paint the pattern can not obtain a clear pattern, the defect of the plywood is exposed as it is difficult to obtain a beautiful pattern.

Therefore, the present invention includes the step of protecting the plate surface by performing a transparent coating after polishing the surface before engraving the surface of the wood.

At this time, the coating amount of the paint coated for the plate surface protection is preferably at least 5 g / s or more, more preferably 7 to 10 g / sft. In addition, the paint may be used as long as the paint commonly used in the art, the coating method may be used as long as it is commonly used in the art.

In addition, the present invention may further include a surface coloring step according to a conventional method before the transparent coating, in this case, to obtain a more vivid pattern by coloring the surface with a paint prepared by mixing a colorant and a paint of a desired color Can be.

According to the present invention, after protecting the surface of the wooden board as described above, by pressing the embossed cylinder engraved with the wood pattern embossed can be obtained the floor plate engraved in the engraved pattern.

In the engraving of the intaglio pattern by using the emboss cylinder, if the acid of the embossed pattern carved in the cylinder is too sharp, the coating film may be broken without being pressed.

In this case, after reducing the coating amount of the paint coated for the plate surface protection to 5 g / s or less, it is preferable to perform the embossed patterning work, then add the coating. At this time, the texture of the embossed pattern transferred to the plywood plate surface may be degraded, so it is preferable to minimize the coating. However, if the texture is not expressed, it may be thickly painted.

In addition, even when the plate coating is thickly raised during the engraved pattern work, the film of the embossed pattern carved in the cylinder may be broken. In this case, the broken coating film must be removed by a polishing machine in a subsequent process.

In addition, in order to more effectively express the wood grain of the wood, after the patterning, the paint may be added by mixing a colorant with a transparent paint or paint to add various colors and patterns, and a paint commonly used in the art may be used. have.

As an example of the additional coating, in the present invention, using a sponge coating roller (coating roller) of low hardness, the paint is applied to the engraved eye and processing surface edge (Bevel) by applying pressure, and then applying the coating roller Use a roller of high hardness to rotate in the opposite direction of the traveling direction to wipe off excess paint left on the plate.

At this time, the hardness of the coating roller having a low hardness is preferably 35 degrees or less, and the hardness of the roller having a high hardness is preferably higher than that of the coating roller having a low hardness.

The paint is preferably a paint prepared by mixing with a transparent paint or a colorant, and preferably a low viscosity paint having a viscosity of 100 ku or less.

Polishing, processing and further coating after the coloring and coating as described above may be carried out according to a conventional method, and the additional coating is preferably used at least one or more transparent paints, and optionally, additives such as anti-wear agents It can be used in an amount of 5 to 20% by incorporation.

Using the method according to the present invention, it is possible to feel the embossing of the intaglio pattern in the touch, and it is possible to clearly give the difference between the plate surface and the inscription to the desired level by engraving the pattern on the transparent painted plate. In the case of coloring, plate color is protected and the surface of the intaglio pattern is protected by the coating film by engraving a pattern on the surface on which the coating film is formed, thereby improving durability.

In addition, it is possible to prevent plate contamination when coloring the intaglio pattern engraved on the coating film can implement a beautiful pattern texture, and the manufacturing process is simple to reduce the manufacturing cost.

The invention also provides a floorboard made according to the method.

Floorboard according to the invention can be used for commercial, home, classroom and public places.
