Description

Particle board manufacturing method

The present invention relates to a particle board and a processing method thereof, and more particularly, a sanding treatment that crosses horizontally and vertically on the front surface of the particle board, and after applying a curable adhesive to the front or rear surface of the particle board, wrap the front and rear surfaces. It is related to a particle board and a processing method thereof, which improves workability for furniture or kitchen furniture by providing a smooth surface without irregularities, and can give a good aesthetic impression, and has a low manufacturing cost.

In detail, the adhesive according to the present invention is transparent, and it is characterized in that it provides a clean appearance even if the transparent PET is attached to the upper part of the particle board through the adhesive.

In general, a particle board is obtained as a structure in which a wood body obtained by crushing and slicing wood is coated with an adhesive, then compression molded, and a wrapping paper is adhered to the front and back sides of the compressed board.

In general, this particle board is widely used for interior and exterior wall finishing materials, partitions, decorative materials, kitchen furniture, and general furniture because of its low manufacturing cost, simple construction, and physical properties that do not degrade strength.

However, the particle board manufactured in this way has difficulty in finishing treatment in which paint cannot be applied or the decorative sheet cannot be adhered because the very roughly molded ends are exposed, and expensive medium-density fiberboards with smoother ends than particle boards ( MDF: Medium Density Fiber) was used, so there was a problem that the manufacturing cost increased.

In addition, if a curable adhesive is used to coat the surface of processed wood such as MDF or to attach a decorative sheet to the surface, excellent adhesive performance can be secured. There was a problem that inexpensive particle boards could not be used for applications that coat the surface of more processed wood or attach decorative sheets to the surface due to unevenness.

On the other hand, the above-described background technology is technical information that the inventor possessed for derivation of the present invention or acquired during the derivation process of the present invention, and is not necessarily known to be known to the general public prior to filing the present invention. .

Like reference numerals in the drawings refer to the same or similar functions over several aspects.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

1 is a flowchart illustrating a particle board processing method according to an embodiment of the present invention.

Referring to FIG. 1, in the particle board processing method according to an embodiment of the present invention, a transparent PET is wrapped on an upper or lower surface of a particle board P using a wrapping apparatus 10 for transparent PET bonding ( S150).

1A is a flowchart illustrating a particle board processing method according to an embodiment of the present invention.

1, a particle board processing method according to an embodiment of the present invention includes, first, compression molding of wood debris into a flat plate shape to have an intermediate density, and forming an upper or lower side of a particle board P in a belt shape. Sanding is performed in the longitudinal direction or the width direction using at least one type of sandpaper (S110).

In one embodiment, in the sanding step (S110), the first sanding process is performed using a belt-shaped No. 180 sandpaper, and at this time, the moving speed of the sandpaper belt rotated by the rollers in the first sanding treatment is 15m/s. It proceeds at speed.

Next, the front part of the particle board P is subjected to secondary sanding treatment in the widthwise direction with a belt-shaped No. 220 sandpaper.

The second sanding treatment is performed by sandpaper No. 220 in a horizontal direction or a width direction perpendicular to the direction in which the first sanding treatment is performed.

At this time, it is connected to the belt-shaped sandpaper driven shaft No. 220 and other rotating rollers connected to the drive shaft to rotate at a constant speed.

At this time, the No. 220 sandpaper coupled to the rollers with respect to the particle board (P) that enters the conveyor in the longitudinal direction by the belt is subjected to secondary sanding in the vertical transverse or transverse direction.

At this time, in the secondary sanding treatment, the moving speed of the sandpaper belt rotated by the rollers proceeds at a speed of 6 m/s.

Next, the front part of the particle board P is subjected to a third sanding treatment in the longitudinal direction with a belt-shaped No. 320 sandpaper.

The third sanding treatment is performed by sandpaper No. 320 in the same direction as the first sanding treatment in a longitudinal direction perpendicular to the second sanding treatment direction.

The belt-shaped sandpaper No. 320 is connected to rotation rollers of other structures connected to the driven shaft and the drive shaft to rotate at a constant speed.

At this time, the belt-shaped sandpaper No. 320 coupled to the rollers with respect to the particle board P entering in the longitudinal direction is subjected to a third sanding treatment in the longitudinal direction by a conveyor belt.

At this time, in the third sanding treatment, the moving speed of the sandpaper belt rotated by the rollers proceeds at a speed of 5 m/s.

Dust of the particle board P, which has been sanded by the above-described step sanding step (S110), is brushed off with a plastic brush (S120).

The dust removal step (S120) is a preparation step for preventing contamination on the surface of the particle board P by dust generated during the three sanding process, and then applying an adhesive and for a complete finish without surface irregularities.

An antistatic cleaning agent is applied to the upper or lower surface of the particle board (P) (S130).

In the step of applying the cleaner (S130), an antistatic cleaner is applied to prevent static electricity generated between the plastic brush and the friction surface of the particle board when dust is removed in the second dust removal step (S140). Prevent.

The reason for preventing static electricity is to prevent the phenomenon that the dust removed by the plastic brush floats in the air and sticks to the surface of the particle board (P) by static electricity.

Dust off the sanded particle board (P) with a plastic brush (S140).

1B shows a structure in which a particle board, an adhesive, and a transparent PET are laminated according to the present invention. Conventionally, since the adhesive itself is yellow, when the transparent PET is adhered to the particle board through the adhesive, there is a problem in that the yellow adhesive is visible through the transparent PET. The adhesive according to the present invention is transparent and provides a clean appearance even if the transparent PET is attached to the upper part of the particle board.

The transparent PET is wrapped on the upper side or the lower side of the particle board P by using the transparent PET bonding wrapping apparatus 10 described later in FIG. 2 (S150).

In the particle board processing method according to an embodiment of the present invention having the configuration as described above, when the front and rear surfaces of the particle board are wrapped after applying a curable adhesive to the front or rear surface of the particle board, a smooth surface without irregularities can be obtained. As a result, particle boards with low manufacturing costs can be used for general furniture or kitchen furniture, improving workability, giving a good aesthetic impression, and waterproofing effect, and coating the surface of processed wood or attaching decorative sheets to the surface. You can do it.
