Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a surface treatment method for an OSB facing material, which is mainly used as a facing material for an OSB facing panel.

[Background Art] In recent years, with changes in lifestyles, housing conditions, and the diversification of housing and urban environments, the state of each member such as walls and partitions that make up the frame of a building is also changing. Specifically, for example, we not only use walls and partitions as structural materials that make up the building frame, but also incorporate a fresh and original feel into the living space of the residence, making the living space more enjoyable and enriching. Attempts are beginning to be made to use this as a means of achieving this goal.

From this point of view, a panel with no OSB surface material pasted has been proposed as one of the panels forming walls and partitions, and has come to be put into practical use.

An OSB (Oriented Strand Board) panel is made by pasting an OSB (Oriented Strand Board) panel onto the surface of a rectangular frame made of core material and bonding it with an appropriate adhesive. be.

O3B surface material is a board made by stacking wooden pieces of about 2 to 3 cm square in a roughly fixed direction and hardening them with a synthetic resin adhesive. It is made by stacking layers and integrating them.

According to such a panel pasted with O8B facing material, the wood pieces of OSB facing material are exposed in a dispersed state on the surface, so it presents a very interesting appearance and allows you to enjoy the feel of the material. It is used to create unique homes.

：Problem to be Solved by the Invention] However, in such an OSB facing panel, since the OSB facing material having the above structure is used as the facing material, the following problems arise. .

That is, since wax has already penetrated into the O3B surface material during press molding, the adhesion of this OSB surface material when pasting it onto a frame is poor. Therefore, O
Even if a panel with 5B facing material is formed, problems arise such as insufficient mechanical strength due to insufficient adhesive strength between the frame and the OSB facing material.

The present invention has been made in view of the above circumstances, and is an OSB surface material that can improve the adhesiveness of OSB surface materials.
The purpose of this invention is to provide a method for surface treatment of facing materials.

[Means for Solving the Problems] The present invention provides a solution by passing an OSB surface material between two rollers, at least one of which has a rough surface, and roughening at least one surface of the O9B surface material. did.

[Function] According to the surface treatment method for 088 facing material of the present invention, at least one surface of the OSB facing material is pressed against a roller having a rough surface, so that the shape of the surface of the roller is transferred, The surface is said to be in a rough state with minute irregularities formed thereon. This improves surface adhesion.

[Example] Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an example of a roller suitably used in the present invention. This roller 1 includes a first roller 4 formed by pasting sandpaper 3 of approximately 40 to 100 mesh on the entire surface of a rubber roller 2 of a one-sided roll coater type;
A normal rubber roller (second roller) 5 is arranged in parallel with a slight gap and is installed so as to be rotatable in opposite directions.

The O8B surface material 6 is passed between the first and second rollers 4°5 thus formed.

0SB (Oriented Strand Board) facing material 6
The board is made by stacking several pieces of wood, approximately 2 to 3 cm square in size, arranged in a roughly fixed direction, and then applying a synthetic resin adhesive to harden the board into a plate shape. It has an integrated configuration. The wood pieces include small pieces that have been cut into appropriate shapes such as plates, rectangular parallelepipeds, cubes, grains, and rods using a shaving machine, or these pieces are further crushed by mechanical impact, roller pressure, etc. The crushed pieces etc. In addition, thermosetting resins are mainly used for the synthetic resin adhesive, and specifically, for example, urea resin, epoxy resin, unsaturated polyester resin,
Noricone resins, phenol resins, and other resins that are in a liquid or viscous state before curing are used. Alternatively, if necessary, additives such as appropriate fillers and colorants may be added thereto.

To outline the manufacturing method of such O5B facing material 6, first, the wood pieces are continuously transferred to an adhesive coating device, and an appropriate amount of synthetic resin adhesive is continuously sprayed onto the wood pieces.
The wood pieces are scattered and piled up while aligning the wood pieces in a substantially constant arrangement direction. Next, heat and pressure are applied under predetermined conditions to obtain a plate-like board with the synthetic resin adhesive in a semi-cured state.

Several boards are prepared, and the wood pieces are successively stacked one on top of the other so that the arrangement directions of the wood pieces are orthogonal to each other, and the boards are laminated and integrated by press molding or the like.

When the OSBS8 surface material thus obtained is passed between the two rollers 4 and 5, its passing speed is 0.5 to 1. O
It is suitable to set it to about m/min.

By doing this, the entire surface of one surface of the OSBS8 surface material (the surface on the side that was pressed in contact with the first roller 4) is pressed by the sandpaper 3. by this,
The surface is a rough surface 7 having fine irregularities formed by transferring the shape of the surface of the sandpaper 3. Also, OSB
When passing the S8 surface material between the rollers 1, no slipping occurs between the OSBS8 surface material roller 1 and the OSBS8 surface material roller 1.

As described above, according to the surface treatment method of the OSB surface material of this embodiment, one surface of the 068 surface material 6 is roughened, and the adhesiveness is improved.

Therefore, when pasting the OSB facing material 6 on the surface of a frame assembled into a rectangular outline to form an O5B facing material-attached panel, the roughened surface 7 of the OSB facing material 6 is If it is adhered to the frame, it can exhibit high adhesion. Therefore, the adhesion reliability of the obtained O5B panel pasted panel is improved, and quality can be guaranteed.

Note that the method for surface treatment of an OSB surface material of the present invention is not limited to the above-mentioned embodiments, and the specific structural requirements can be changed as appropriate in implementation.

For example, in the above embodiment, the first roller 4 was a rubber roller 2 whose surface was made rough by pasting sandpaper 3 on the surface. If available, a configuration other than this can also be used.

Further, in the embodiment, one roller (the first roller 4
) was used with a rough surface, and the other roller (second roller 5) was a regular rubber roller, or both rollers (1.5) had rough surfaces. You can. In this case, both surfaces of the OSB surface material 6 are roughened to improve adhesion, so that high adhesive performance can be achieved by attaching the rough surfaces to the frame.

[Effect of the Invention 5] As explained above, according to the surface treatment method of the OSB surface material of the present invention, at least one surface of the OSB surface material is formed with fine irregularities and is brought into a two-set surface state. , adhesion is improved. Therefore, when forming a panel with OSB facing material attached, high adhesion between the 088 facing material and the frame is ensured, so the quality of the OSB facing material applied panel can be guaranteed. .
