Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a baked cedar-style or floating-style decorative board.

Conventionally, the method of obtaining baked cedar-style or floating-style decorative boards is to use natural materials with a clear distinction between spring wood and summer wood, for example.
The surface of cedar wood, pine wood, etc. is burnt and carbonized by taking advantage of the difference in hardness and burning speed between the spring wood part and summer wood part, and then sandblasting, which creates shading due to carbonization and unevenness due to polishing. There was a burnt cedar decorative board or floating decorative board that realized this.

However, in recent years there has been debate about the depletion of wood resources, and the current situation is that so-called precious woods suitable for making roasted cedar floats are becoming difficult to obtain due to their price and supply capacity.

In view of the current situation, the present inventor investigated a method of economically and constantly obtaining a burnt cedar style or floating style decorative board using low-grade logs, and as a result, came up with the present invention.

The technical idea of the present invention is that the same or different types of wood veneers are interposed with a self-heat-extinguishing adhesive or an adhesive that does not have self-heat-extinguishing properties by adding a flame retardant, and the unevenness is in a male-female relationship. A plurality of sheets are pressed and assembled using the lower template, and this is made into an uneven flitch.The flitch is cut to an arbitrary thickness using a slicer or a half rotary, and the thin pieces are made into a wooden base material,
This relates to a method for producing baked cedar-style decorative boards, which is characterized by adhering to a ceramic base material, etc., and then burning and carbonizing only the very surface of the thin piece, and subjecting the surface to processing such as sanding or brushing. It is.

The method for producing decorative laminates according to the present invention will be described in detail. (1) Rotary veneers are obtained from logs of Avitong, Kabul, White Merante, Red Lauan, White Celaya, Juruton, Calambayan, etc.

■ Examples of self-heat-extinguishing adhesives include urea resin, melamine resin,
Amino resin adhesives such as phenol resins and benzoguanamine resins, or flame retardants such as ammonium phosphate,
Using an adhesive that has self-extinguishing properties by adding ammonium bromide, etc., one or more types of veneer board (■) are bonded to the top and bottom templates (Japanese Patent Laid-Open No. 49626
No. 12 describes how to make it) to create a concavo-convex flitch.

Note that although a cold press method is mainly employed as a press method in the case of molding and laminating, a hot press method or a high frequency drying method (heating) may be employed depending on the case.

■ Cut the above flitch to the desired thickness using a half rotary or slicer.

Various patterns can be obtained on the veneer depending on the shape of the template (ii).

By mixing a coloring agent into the adhesive described in (2), a remarkable pattern can be obtained.

■ Adhere the veneer thin piece of ■ to a wood base material (plywood, particle board, etc.), a ceramic building material base material (pulp cement board, asbestos cement silica board), etc. with adhesive.

■■ Burn and carbonize the very superficial layer of the veneer-attached decorative board, generally to a depth of about one-fifth to four-fifths of the thickness of the attached veneer. Heat uniformly using a jet dryer, direct flame method, etc., and create local differences in the degree of carbonization.

■ By brushing, sanding, etc. to the desired degree on the surface of the product that has gone through the process of (■), a desired soft wood part is created by utilizing the local differences in hardness and softness based on the local differences in the degree of carbonization. The wood texture of natural precious wood made of spring and summer wood is reproduced on the veneer-covered decorative board.

Depending on the case, a top coat is applied to the surface of the decorative veneer board of 0 ■.

According to this invention, due to the difference in hardness due to the difference in the degree of carbonization created through the steps from ■ to ■ or O above, this corresponds to the spring wood portion and the summer wood portion, and the surface is formed along the wood grain. A veneer laminated decorative board with a very unique wood texture with graceful unevenness is produced, and the product value is high.As shown above, the extremely low price of South and North Sea wood is used, so the price is very low. It has the features of being low cost and luxurious in appearance.

Claims (1)

[Claims] 1 Wood veneers of the same or different types are interposed with a self-heat-extinguishing adhesive or an adhesive made with self-extinguishing heat by adding a flame retardant, using upper and lower templates with male and female unevenness. Multiple sheets are pressed together and made into an uneven flitch.
The flitch is cut to a desired thickness using a slicer or a half rotary, and the thin piece is attached to a wood base material, a ceramic base material, etc., and then only the very surface of the thin piece is burned and carbonized. A method for producing a baked cedar-style decorative board, which is characterized by applying processing such as siding or brushing.
