Description

[Detailed Description of the Invention] The present invention relates to a method for producing a reinforced decorative board suitable for building materials such as flooring, salvage, and ceiling materials, as a face material for each piece of furniture, and for other decorative materials. Synthetic resin injection treated wood boards, which are made by injecting synthetic resin liquid into thin wood boards and forming scissors, are generally used in W and P.

On) is a material that improves the strength, abrasion resistance, dimensional stability, stain resistance, etc. of wood materials, and uses injected resin to increase the transparency of wood boards and create deep wood grain patterns. It is commonly used as a surface decorative material for architectural materials such as floorboards.

However, although it has the advantages as mentioned above, the synthetic SRS injection treatment board material has the disadvantage that the injected resin will become bulky and the whole will become uniform afterward, so it cannot be treated with a cutter or the like like a natural wood veneer. Formation of arbitrary shapes 11
If you try to form an e-space, it tends to crack or chip, making it difficult to walk, which makes it difficult to use it as a decorative material for decorative boards between parquets or checkered spaces. On the other hand, as a method of forming decorative boards between books and checkers using such synthetic resin injection-treated lumber boards, a decorative piece is formed by lining and reinforcing a synthetic resin-injected thin wood board with plywood, etc. Is it possible to arrange the even end surfaces of each decorative piece in a substrate shape and glue them together? If the above decorative material is finished coated, the synthetic resin injection treated thin plate has almost no paint absorption, so the decorative pieces will not absorb the paint. The paint accumulates in the joints of the pieces, and the paint pool at the m-th point of the decorative piece becomes foamy when it dries and hardens, causing it to stick in the shape of foam, which impairs the appearance and also causes the paint to be colored to adjust the color tone of the decorative material. When clear coating is applied, there is a problem in that the paint pools appear as colored streaks at the joints of the decorative surface, spoiling the natural look.

In order to eliminate such drawbacks, the present invention aims to create a decorative base for large plates by pasting synthetic resin injection-treated wood thin plates (hereinafter referred to as WPC thin plates) to an intermediate plate made of an essential material or the like that has a paint-absorbing property. After forming the material, this decorative substrate is divided into a plurality of decorative pieces, and the peripheral end surface of the WPO thin plate piece of this decorative heather is chamfered to form an inclined end surface, and then the plurality of decorative pieces are parquet on the substrate. The prepared pieces are arranged and glued between checkers to form a large decorative board, and then a finishing coat is applied to the entire surface of the large decorative board, and a V is formed between the inclined end faces of adjacent decorative pieces. The present invention provides a method for manufacturing a reinforced decorative board, which is characterized by absorbing the paint accumulated in the grooves into the intermediate board pieces and forming a uniform paint layer after drying. To explain the drawings, a thin WPC board (1) is obtained by injecting a synthetic resin liquid into a thin wood veneer having a thickness of about 2 cm, such as a sliced veneer or a rotary veneer.

As a method for injecting resin liquid into a thin wood veneer, a method such as pressurized injection, reduced pressure injection, or reduced pressure pressurized injection is adopted.

The injected synthetic resin liquid can be any of the following: synthetic resin liquid, additive polymerized resin liquid, water-soluble synthetic resin liquid, and solvent-based synthetic resin liquid. Appropriate solvents, softeners, curing agents, colorants such as pigments and dyes, and other additives may be mixed.

The WPO thin board (1) obtained in this way is made into a wood veneer, a wood board such as plywood, verdicle board, hardboard, or a monolithic board such as plaster or calcium silicate board with paint absorbency. A large decorative base material (3) is obtained by integrally bonding the intermediate plate (2) with a thickness of 6 degrees with an appropriate adhesive. Materials with good water absorption properties are used, and among the above-mentioned plate-like materials, fiberboards and low specific gravity inorganic boards are particularly preferable because they absorb paint easily.

Next, cut this decorative base material (3) with a circular saw. Shitasaw, 40
By dividing it into several pieces with a suitable cutting tool such as a chishi, a plurality of decorative sheets (4) are obtained by integrally polymerizing the WPC thin plate piece (LA) on the intermediate plate piece (2a).

The dimensions and shape of the decorative piece (4) are set depending on the array pattern to be obtained, for example, small checkered pattern, large checked pattern, marquetry**, etc.

This decorative piece (4) is obtained by heath-cutting the WPO thin plate (1) in a polymerized and integrated state with the intermediate plate (2), unlike when cutting the WPO thin plate (1) alone, so there is no chance of chips or cracks occurring in the WPC thin plate. It can be cut easily and the actual accuracy is improved, and even when chamfering is performed, it prevents tearing of the intermediate plate piece (2a) on the back side or the WPO thin plate piece (1a) on the front side, and it also gives an appropriate thickness. Because of this, chamfering can be easily and simulatively performed.

Next, the end face of the WPO thin plate piece (la) 0!1 of the decorative piece (4) thus obtained is cut with a cutter or the like to form an inclined end face (5).◎ This inclined end face (5) is a decorative piece. It may be within the thickness range of the WPC thin plate piece (la) of base (4) or more, but the lower end of the inclined edge @ (5) is coincident with or close to the surface of the intermediate plate piece [2a]. It is preferable to install it in a range such as 1 intermediate plate piece (2a) or the inclined end face (5), and make sure that II does not come out with a wide width◎ In other words, the above-mentioned II inclined end face (5) should be installed during the subsequent painting. , along one end tl (5), remove excess paint from the intermediate plate piece (2
Since it is necessary to absorb the paint flowing down on the side end face of a), it is recommended to provide it at the lower end or at S reaching the surface of the intermediate plate piece (2'h) to block the absorption of the paint. ) to the intermediate plate piece (

Afterwards, the entire surface of this decorative board (2), including the V-shaped groove (7), was coated with uretashi l1i111, a! Apply a resin paint such as a resin paint and dry it at room temperature or at a high temperature using an appropriate heating dryer. At this time, the decorative board (
The paint that is about to accumulate in the V-shaped groove (7) in 2) is spread evenly from the acid part of the V-shaped groove (7) to the intermediate plate piece (2&) on both the decorative piece surface and the V-shaped groove surface. A layer (8) can be obtained.

Next, specific examples of the present invention will be shown.

Example 2. 0mm thick Stainless steel veneer was heated to 300mm by 4o decimal
X1500mM! After cutting the plate into a rectangular plate of size 1, the plate was placed in a vacuum cooker, evacuated to 101111F, and left for 60 minutes. (2) Then, in the vacuum pot, put a synthetic resin solution made by adding 100 parts of unsaturated polyester resin, 40% by weight of styrene resin and 1% of BPO as an anti-inflammatory agent, and leave it for 30 minutes. 6. Take out the Soft Bruce veneer that has been treated with resin injection from the vacuum pot.6. Place it on a medium-thick 111i1s plate with urea resin adhesive and
By hot pressing for 10 minutes under the conditions of 5°0110"/cj, a decorative board was obtained with a resin-injected veneer adhered to a medium specific gravity 5iJlk board. It is divided into multiple pieces, and then a cutter is used to cut the resin-injected veneer of each decorative piece into 45 pieces on the west end surface.
Chamfered at a degree angle.

A plurality of these decorative pieces are combined and arranged on 15 square pieces of 5-sided plywood with a small groove between adjacent end faces,
After applying heat and pressure for 6 minutes at 110°C and 10"/- condition F, the pieces were adhered together via the urea resin adhesive applied to the backing of the decorative piece, and then the surface was finished with a urea resin paint. The paint infiltrated into the V-shaped grooves formed by the face kicks of each face and base was absorbed into the end of the matted board on the back side of the synthetic resin injection-treated thin board, and then heated and dried. .

The decorative board obtained in this way exhibits the most striking appearance when all surfaces including the surface of the V-shaped groove formed by the beveled decorative piece are coated with a smooth Ilk surface. In addition, in the decorative board thus obtained, the paint penetrates and is absorbed into the lower part of the V-shaped groove at the joint of each decorative piece, and this makes the end surface of each decorative piece join. The joints of the decorative pieces did not open due to temperature or humidity carbonization, and the joints between the decorative pieces were strong enough to maintain good cosmetic properties for a long period of time.

As described above, the present invention involves (1) pasting a thin wooden board treated with synthetic resin injection onto the surface of an intermediate board such as a wood material having paint absorbing properties to form a large-sized decorative base material; The decorative heather is cut into several decorative pieces by cutting into several decorative pieces, and the peripheral end faces of these decorative heather synthetic resin-injected thin wood pieces are chamfered to form inclined end faces. By bringing the end faces of the intermediate board pieces into contact with each other on the substrate, or by arranging and gluing them together with a small gap between the end faces, the synthetic resin injection-treated wood thin board pieces of the adjacent decorative surfaces can be bonded. A large decorative board with V-shaped grooves formed between the inclined end faces is obtained, and then a finishing coat is applied to the entire surface of the gunfire decorative board to remove paint accumulated in the V-shaped grooves from the intermediate board. Since this relates to a method for producing reinforced decorative boards characterized by allowing the pieces to absorb paint and unifying the paint, resin-infused thin wood boards are glued to an intermediate board and then cut into pieces of predetermined dimensions. As a result, resin-injected thin wood sheets can be cut without corner chips or cracks, which improves blood flow and makes handling easier.Of course, these decorative surfaces do not break when assembled. The synthetic resin injection-treated thin plate pieces are cut out on one side and arranged on the board, and then the final coating is applied.
Even if the panels are arranged butt-to-edge, the paint that accumulates at the joints will flow down along the inclined edges and will penetrate and be absorbed by the intermediate plate lining the bottom of the synthetic resin-injected thin plate pieces, eliminating the accumulation. V caused by the inclined end surface of each decorative piece.
Both the face of the letter-shaped groove and the face of the decorative piece can be coated with a paint layer of a uniform thickness to form a coating in an irregular coating direction.
It is possible to finish the joints of decorative heather with a natural feel, without impairing the cosmetic properties of synthetic resin injection treated thin sheets.
