  However, since the members as described above are formed by sheet metal processing of steel plates, if they are formed long, the weight increases, and it cannot be said that the productivity is high due to batch production, and further during handling There was a danger of cutting their hands at the end.

  Accordingly, the present invention is intended to solve the above-described problems, and to provide a composite material that is light in weight, high in productivity, and has no danger of cutting hands.

In order to achieve the above object, the present invention is configured as follows.
That is, in the composite material according to the present invention, a stainless steel foil is stuck along the longitudinal direction on the surface of a base material formed by extruding a synthetic resin, and both side ends of the stainless steel foil are embedded in the base material, The synthetic resin is characterized in that a filler that suppresses expansion and contraction of the thermoplastic synthetic resin due to heat is blended with the thermoplastic synthetic resin.

  According to the present invention, since the stainless steel foil is stuck along the longitudinal direction on the surface of the base material formed by extruding the synthetic resin, it is light and efficiently produced while maintaining the metallic design. Since both ends of the stainless steel foil are embedded in the base material, there is no danger of cutting hands at the ends, and the synthetic resin is further added to the thermoplastic synthetic resin. Since a filler that suppresses expansion and contraction due to heat is blended, the stainless steel foil and the base material can be expanded and contracted integrally, so that the stainless steel foil and the base material are prevented from peeling or warping. be able to.

  In the present invention, the filler may be one or more selected from the group consisting of calcium carbonate, talc, clay, carbon fiber and glass fiber.

  In the present invention, a thermoplastic synthetic resin made of an ABS resin is used as the synthetic resin and talc is used as a filler, and 5 to 30 parts by weight of talc is added to 100 parts by weight of the ABS resin. It may be.

Embodiments according to the present invention will be specifically described below with reference to the drawings.
FIG. 1 is a cross-sectional view showing an embodiment of a composite material according to the present invention, which is used as a protruding corner member on a wall surface, and FIG. 2 uses the composite material shown in FIG. It is a perspective view which shows the structure of a protrusion corner. In this composite material 1, a decorative portion 2 having a hollow square cross section that forms a protruding corner and a corner portion of the decorative portion 2 are notched, and a support piece 3 that contacts the wall surface W extends from the notched portion 4. The panel P is attached so that its back surface is brought into contact with the support piece 3 and its end surface is abutted against the decorative portion 2.

  And in this form, the said decorative part 2 and the support piece 3 are the base materials 5 formed by extrusion molding a synthetic resin, and the stainless steel foil 6 is stuck to the surface of the decorative part 2 along the longitudinal direction. The support piece 3 is embedded with an aluminum foil 7 to enhance the strength.

  Further, both ends of the stainless steel foil 6 are embedded in the base material 5, and the synthetic resin is blended with a thermoplastic synthetic resin and a filler for suppressing expansion and contraction due to heat of the thermoplastic synthetic resin. By doing so, the expansion and contraction of the thermoplastic synthetic resin is suppressed, and the stainless steel foil 6 and the base material 5 can be integrally expanded and contracted, so that the stainless steel foil 6 and the base material 5 are peeled off, Since it can suppress that curvature generate | occur | produces, it is preferable.

  Moreover, you may use the 1 type (s) or 2 or more types selected from the group of calcium carbonate, a talc, clay, carbon fiber, and glass fiber as said filler.

  The synthetic resin is not particularly limited, and an olefin resin such as polyethylene or polypropylene, a vinyl chloride resin, an ABS resin, or the like is appropriately used. In this embodiment, a thermoplastic synthetic resin made of an ABS resin is used. Talc is used as a filler, and 5 to 30 parts by weight of talc is preferably blended with 100 parts by weight of ABS resin. When the amount of talc is less than 5 parts by weight, the creep resistance is not good, and when the amount of talc exceeds 30 parts by weight, the impact resistance is lowered, which is not preferable.

  FIG. 3 is a cross-sectional view showing another embodiment of the composite material according to the present invention. Like FIG. 1, this embodiment is used as a protruding corner member on the wall surface, and is shown in FIG. The shape of the decorative portion 2 is different from that of the hollow portion, and the support piece 3 that is in contact with the wall surface is formed on the cutout portion 4. The panel extends in an L-shape from one end, and the panel is attached with the back surface abutting against the support piece 3 and the end surface being abutted against the decorative portion 2.
