Description

[Detailed description of the invention] The present invention relates to materials for fittings, doors, or panels used in the interior of houses, etc., particularly for unitized interiors such as prefabricated houses and high-rise apartments, such as washbasin units, toilet units, and partitions in Western-style rooms. This relates to composite boards for fittings, doors, or panels used for walls, etc.

Conventional wall structures such as doors and panels are made by attaching inorganic flat plates such as gypsum board or polyester-impregnated asbestos boards to the outside of the wooden frame, or by attaching flat plates made of aluminum profile extrusions to give them flame retardancy. This goal is achieved by enclosing it in a frame.

Such materials have low impact strength, require large wall thicknesses, are heavy and require a large number of artificial parts, and require a sturdy mounting structure for installation, resulting in lower material costs and Both construction costs are high, and in addition, these plates cannot be subjected to post-processing such as bending.

Synthetic resin sheets are lightweight, strong, and have excellent bending properties, but when used in wall structures such as panels, their flame retardance is highly problematic.

Furthermore, when pasting such a synthetic resin sheet to a wooden crosspiece or a wooden frame with honeycomb blocks attached, it is necessary to avoid curing shrinkage of the adhesive and distortion due to processing during pressing.
If the sheet thickness is thin, sink marks will appear along the underlying wooden bars or honeycomb lines that can be clearly observed from the outer surface of the panel wall, so the sheet thickness is required to be Q, 9 mm or more.

However, if the thickness is 9 mm or more, the material cost will be high and bending will be difficult.

In general, the panel size is 0.9 m x 1.8 m,
Rectangular fixed-length panels such as 0.9 m x 2.4 m are connected and assembled using fasteners such as metal fittings to form a specified enclosure.
Panel joints, especially the joints at wall corners, are an extremely serious problem both aesthetically and in terms of preventing acoustic leakage, and it is no exaggeration to say that this is an obstacle to the widespread use of unit panel assembly in architectural interiors.

In such cases, if there is a flame-retardant panel exterior material that can be easily bent, the walls, especially the corners of unit structure enclosures (washroom units, toilet units, Western-style rooms, etc.), can be formed into continuous walls. Problems can be solved.

An object of the present invention is to provide a composite plate for fittings, doors, or panels using a flame-retardant, lightweight, and easily bendable composite sheet that eliminates the drawbacks of conventional materials.

The gist of the present invention is to provide a core material selected from paper, asbestos sheet honeycomb core block, feather core block, or wooden pillar in the form frame, and to provide a core material with a thickness of 0.2 mm on at least one side of the core material. Composite board for fittings, doors or panels made by laminating a composite sheet made by laminating ~0.8mm hard or semi-hard synthetic resin sheet and 0.2-1.5mm thick asbestos sheet with the asbestos sheet side inside. exist.

The synthetic resin/asbestos composite sheet used for the outer surface of the composite board according to the present invention is made by laminating wooden pillars, honeycomb blocks, etc. in a form filled as a core material to form doors, panels, etc. Therefore, by utilizing the nonflammability and flexibility of asbestos sheets such as the impact resistance and easy bending properties of synthetic resins, and by combining the two, we succeeded in preventing sink marks caused by the base core material that appear on the surface of the synthetic resin layer. It is something.

To explain the present invention based on the drawings, Fig. 2 is a sectional view of a composite sheet applied to the present invention, in which an asbestos sheet 2 is laminated on a hard or semi-hard synthetic resin sheet 1 with a well-known suitable adhesive 3. has been done.

Note that lamination is not limited to adhesion, and may be performed by means such as fusion bonding.

As the synthetic resin sheet, ABS resin, hard or semi-hard polyvinyl chloride sheet, polyethylene sheet, etc. are used, and the sheet thickness is used in the range of 0.2 to Q, 8 mm.

If it is thinner than 0.2 mm, the impact resistance, water resistance, chemical resistance, etc. will be poor, and if it is thicker than 0.8 mm, there will not be much improvement in the properties of the wire, and the bending workability will deteriorate and the cost will increase. It is from.

In addition, the asbestos sheet must be in the range of 0.2 to 5 mm; if it is thinner than 0.2 mm, the effect of imparting flame retardancy will be poor, and the effect of preventing sink marks on the core base material will be poor; This is because, even if the thickness is made thicker than 5 mm, the effect of imparting flame retardance will be slight and the bending workability will also deteriorate.

Next, an example of a composite board for a panel to which the above composite sheet is applied will be described based on FIG. 1. A core material 5 filled with honeycomb blocks is provided in a wooden square frame 4, and one side of the core material is A resin/asbestos composite board is bonded so that the asbestos sheet surface is enclosed, and a wood plywood 6 is bonded and laminated on the other surface of the core material to form a panel composite board.

Further, the composite sheet may be laminated in place of the wood plywood, and depending on the application, one side of the core material may not be laminated.

Even if the synthetic resin layer is thinner than Q, 9 mm, sink marks will not be exposed along the lines of the core material because the asbestos sheets are laminated.

As the core material, a core material selected from paper, a honeycomb core block made of asbestos sheet, a feather core block, or a wooden pillar is used, and asbestos sheet and core material,
The plywood and the core material can be bonded together using the same adhesive, such as a vinyl acetate adhesive.

The above-mentioned situation also applies to fittings and doors.

In addition, for example, a frame with upper and lower frames bent into a key shape like a bolthole can be filled with honeycomb blocks, wooden frames, etc. to form a bent core material surface, and then a synthetic resin or
By gluing the asbestos composite sheet, it is possible to form a panel with a continuous wall structure with no joints in some corners, and this panel board can be used to assemble interiors with unit panels such as washbasin units, toilet units, western-style walls, etc. It becomes possible.

Since the present invention has the above-mentioned configuration, it is lightweight using a honeycomb block, a feather core, a wooden frame, etc. as a core material, complies with flame retardant standards or semi-flammable standards, and has high impact strength.

In addition, since the composite sheet of the outer layer is suitable for post-processing such as bending, it is possible to construct a seamless panel wall surface in a part of the corner, making it possible to use unit panels for building interiors, and the material price, construction price, and installation price are low.

Since the outer layer is a synthetic resin sheet, it has excellent water resistance and chemical resistance, and is suitable for interior parts where water is used.

In addition, in the manufacturing process for panels, etc., wood plywood is often laminated on one side, but the same adhesive can be used to bond composite boards, so the gluing process for panels, etc. becomes a single step.
This has the advantage of reducing manufacturing costs.
