Description

Laminated Lumber product and said process method

TECHNICAL FIELD This invention relates to the adhesive agent product of heterogeneous wood, and its manufacturing method.

Until now, the method of aggregate bonding of wood has been known academically, but there have been no examples of commercialized aggregate adhesive products that have been specifically studied according to its purpose and use. However, there is no known method of collectively bonding the same type of wood, but there have been no attempts to commercialize it for educational or woodworking by utilizing the texture of different types of wood.

The present invention has been made in view of the above-mentioned points, and in particular, it is an object to provide a furniture, a commemorative wooden handicraft and a building interior material by collectively bonding a variety of beautifully patterned wood.

Another object of the present invention is to provide a preferred method for producing the product.

The object of the present invention is that the wood for core after manufacturing, drying, cutting, plaining the wood for the frame and the wood for the core simultaneously or separately. After laminating using secondary adhesive, and after secondary cutting, the product is formed by laminating the frame wood and the second cut core wood separately or simultaneously with the finishing. Achieved by secondary plaining, then sanding, painting, printing and / or marking.

Hereinafter, the specific configuration and operation of the present invention will be described by the process and preferred embodiments, but the scope of the present invention is not limited only to these embodiments, but by a person skilled in the art by changing the order of combining or reducing or expanding the process of the present invention Of course, it can be expanded, of course, such a change of the process is of course within the scope of the present invention.

1 is a process chart showing a preferred embodiment for producing the present invention aggregate adhesive article.

Figure 2 is a photograph of a memorial woodwork product produced according to the method of the present invention.

The present invention, as described in detail the manufacturing method in step 1 in the process, the method of manufacturing a product by the aggregate bonding of the heterogeneous wood of the present invention comprises the steps of: lumbering the wood for the frame or core; Drying; Tailoring; In the case of the finishing step and the core wood, the step of collectively bonding the different kinds of wood; Secondary cutting the aggregate bonded wood; Secondary laminating the secondary cut cored adhesive wood for the core and the framed wood for the frame; Secondary Planning; Painting; Printing and / or marking to commercialize.

Can be selected and used in the present invention, the frame wood can be a variety of species, but in consideration of economical and ease of commercialization such as printing and marking was used pine or oak.

On the other hand, the core wood can be selected and used in the present invention can be a variety of species, for example, birch, sputum, croquette, elm, elm, wild buckthorn, acacia, wild cherry, beech, Natural rare species such as oak tree, chestnut tree, lumber tree, pyrite tree, and oyster oak tree, and domestic species that can be beautifully patterned can be used.

In the present invention, the core wood for lumbering, drying, cutting and finishing after bonding, the core wood and the frame timber for finishing, drying, cutting, finishing and finishing the frame wood secondary gluing ( As the adhesive used for secondary larminating, an aqueous adhesive is preferable, and vinyl acetate acetate, melamine resin, and phenol resin are used as the thermosetting adhesive.

An embodiment (timber) of the adhesive product of the heterogeneous wood produced by the method of the present invention is shown in FIG. 2.
