Abstract

PROBLEM TO BE SOLVED: To give an appearance of stainless steel tone or wood texture tone to the surface of a partitioning member used in a door stop edge, door edge, etc., by forming a synthetic resin layer on the surface of an aluminum material, and affixing thereto a thin film of polyester. SOLUTION: A synthetic resin is applied to the surface of an aluminum material 1 formed by extrusion into a specified section so that a synthetic resin layer 2 is formed, and thereon a thin film of polyester 3 is affixed. The polyester film 3 is a laminate of a base film, die separator layer, protective top coat, decoration layer, backup color layer, and thermo-sensitive adhesive layer, and this laminate is pressed by a hot roller and affixed to the resin layer 2 on the surface of the aluminum material 1, and the base film is exfoliated from the die separator layer so that the protective top coat comes up to the surface. Accordingly the wood texture is formed as a decoration layer or the use of a stainless steel foil achieves a surface condition excellent in the appearance.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aluminum building member, and more particularly to a building partition member.

[0002]

2. Description of the Related Art Aluminum extruded materials and stainless steel materials are often used as partition members. For example, a door stop edge, a door edge, a skirting board, a floor rail, a headboard and the like made of the above materials are used for partitioning a toilet. Here, when comparing an aluminum material and a stainless steel material, a stainless steel material having a glossy appearance is suitable, and a stainless steel material is also excellent in terms of strength.

However, it is not easy to extrude a stainless material into a predetermined cross-sectional shape, and it is generally manufactured by bending a plate material. For that reason, it is impossible to manufacture a member having a complicated shape, and there is a problem that the cost becomes extremely higher than that of the extruded material of aluminum. In addition, burrs and burrs are left on the edges when the plate material is cut for bending, and the burrs and burrs are often injured during the assembly work of the partition.

Of course, it is possible to plate the surface of an aluminum material to give it a stainless-like appearance, but a facility for plating is required, and if this facility cost is added to the manufacturing cost. For example, the cost cannot be lower than when stainless steel is used.

[0005]

As described above, the aluminum materials and stainless steel materials conventionally used as partition members have the above-mentioned problems. The problems to be solved by the present invention are these problems, and provide a building material in which an aluminum material is used and the surface thereof has a stainless steel appearance or a surface state which is preferable in appearance.

[0006]

The building member of the present invention is an aluminum member, and a thin film made of polyester is attached to the surface of the member. It is also possible to do so. This polyester thin film has a strong coating film structure coated on a film and comprises a release layer, a protective topcoat layer, a decorative layer, and a heat-sensitive adhesive layer.

By the way, this polyester thin film is adhered to the surface of the aluminum material by a heating roller, and after the adhesion, the base film on the surface is peeled off from the release layer and removed. In this case, according to the present invention, the polyester thin film is not directly attached to the surface of the aluminum material, but a synthetic resin layer is formed on the surface of the aluminum material, and the synthetic resin layer is interposed. The synthetic resin layer enables more firm adhesion. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

[0008]

1 is an enlarged sectional view of an extruded aluminum construction member of the present invention. 1 in the figure is an aluminum material,
Reference numeral 2 represents a synthetic resin layer, and 3 represents a polyester thin film. Here, the aluminum material 1 is a member extruded into a predetermined cross-sectional shape, and is, for example, a skirting board or a headboard having a U-shaped cross section, a floor rail, a stud having a square cross section, or a circular arc. It may be a curved door edge.

A synthetic resin layer 2 is formed by coating the surface of the aluminum material 1 with the synthetic resin, and a polyester thin film 3 is attached to the upper surface of the synthetic resin layer 2. Needless to say, the synthetic resin layer 2 does not necessarily have to be formed by painting, and a synthetic resin film can be attached. Incidentally, an enlarged view of the cross section of the polyester thin film is shown in FIG.

Reference numeral 4 is a base film, 5 is a release layer, 6 is a protective top coat layer, 7 is a decorative layer, 8 is a backup color layer, and 9 is a heat-sensitive adhesive layer. The polyester thin film generally has a thickness of about 20 μm and is attached to the surface of the synthetic resin layer 2 formed on the aluminum material 1 and pressed by a heating roller. That is, the adhesive layer is melted by heating and adheres to the synthetic resin layer 2.

The adhered polyester thin film separates the base film 4 from the release layer 5 to expose the protective top coat layer 6 on the surface. The release layer 5 is made of a silicone resin or the like, and the base film 4 can be easily peeled off. Therefore, since the surfaced protective topcoat layer 6 is transparent, the pattern drawn on the decorative layer 7 is surfaced.
For example, if a wood grain pattern is formed on the decorative layer 7, the aluminum material 1 becomes a wood grain member. If a stainless foil is used as the decorative layer 7, the aluminum material 1 has the appearance of a stainless material.

FIG. 3 shows a case where a polyester thin film is attached to an aluminum extruded material having a semi-circular cross section.
Since it is an extruded material, the aluminum member 10 is not angular on both sides and forms a roundness of a predetermined size, and the polyester thin film 3 is adhered to this roundness. As described above, the aluminum building member of the present invention is one in which a synthetic resin layer is formed on the surface and a polyester thin film is further adhered, and the following effects can be obtained.

[0013]

By adhering a polyester thin film to the surface of the aluminum building member of the present invention, a stainless steel surface, a wood grain surface or the like can be formed instead of the original aluminum surface. However, the cost is lower than that of a member obtained by bending a stainless material, and the cross-sectional shape is not restricted by the shape obtained by bending, and various members that have a stainless appearance can be provided.

By peeling off the base film of this polyester thin film, the protective top coat covers the surface and prevents the occurrence of scratches due to contact, etc., and maintains a beautiful appearance forever. If an extruding member is used, there are no burrs or burrs on the edges or corners, and there will be no contact and injury during the assembly work.
