Abstract

(57) Abstract: [Purpose] The present invention is in the Rukoto Kyosu Hisage the interior material of an automobile excellent in lightweight and moldability. [Structure] A corrugated cardboard 11 using a corrugated core material 12 and a surface material 13 made of stretchable nonwoven fabric is used as a material for an interior material 14.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an interior material used in, for example, an automobile.

[0002]

[Background of device]

 For example, in automobiles, cardboard is used as a base material for interior materials such as ceiling materials and door trims. The corrugated cardboard (1) comprises a corrugated core material (2) and a surface material (3) adhered to the core material (2) as shown in FIG. The surface material (3) is made of paper. However, the corrugated cardboard (1) made of paper is poor in formability due to the low extensibility of the paper, and wrinkles and cracks are generated in the deep-drawing forming part. There are problems such as occurrence of noise, poor soundproofing, and large weight.

[0003]

[Prior art]

 Conventionally, as a means for solving the problems of the above cardboard made of paper, a cardboard in which a surface material made of non-woven fabric is adhered to both surfaces of a core material made of paper (Japanese Patent Laid-Open No. 61-29532). ), Corrugated cardboard using cork sheet as the surface material and / or core material (Actual No. 4-83742), corrugated cardboard using non-woven fabric and cork sheet as the surface material (Actual No. 4-72933) ) Etc. are provided.

[0004]

[Problems to be solved by the device]

 However, in the cardboard disclosed in JP-A-61-29532, the surface material is made of non-woven fabric, but since the core material is paper, the moldability cannot be said to be sufficient, and there is a problem with soundproofing as well. In the corrugated sheet of Kaihei 4-83742 and Japanese Patent Application No. 4-72933, the cork sheet does not have sufficient stretchability, good moldability cannot be obtained, and rubbing with the vehicle body panel may cause a low tone. However, there is a problem that the soundproofing is not sufficient.

[0005]

[Means for Solving the Problems]

 The present invention provides a corrugated core material (12) made of a non-woven fabric and a surface material (13) made of the non-woven fabric adhered to the core material (12) as a means for solving the above conventional problems. The present invention provides an interior material composed of a cardboard (11) constituted by the above.

[0006]

[Action]

 Since the cardboard (11) of the present invention uses a non-woven fabric for both the core material (12) and the surface material (13), the cardboard (11) as a whole has excellent extensibility and contains a large amount of air. Since it is rich in sound insulation and cushioning, it produces no low-grade sound due to rubbing against the body panel, and is extremely lightweight and breathable.

[0007]

【Example】

 The present invention will be described with reference to an embodiment shown in FIGS. 1 and 2. A cardboard (11) comprises a corrugated core material (12) and a surface material (13) adhered to the core material (12). Composed. The core material (12) and the surface material (13) are both made of non-woven fabric, and the non-woven fabric is made of polyester fiber, polyamide fiber, polyethylene fiber, polypropylene fiber, acrylic fiber, acetate fiber, cotton fiber, wood fiber, A non-woven fabric that uses one or more types of fibers such as organic fibers such as bamboo fibers, glass fibers, ceramic fibers, inorganic fibers such as carbon fibers, which are obtained by binding the fibers with a synthetic resin binder, needles Those entangled by punching, etc., and those containing low melting point fibers such as low melting point polyester fibers, polyethylene fibers, or polypropylene fibers are those which are heated and fused by the low melting point fibers. Acrylic resin, vinyl acetate resin, styrene resin, urethane resin, melamine resin, urea resin, synthetic resin such as phenol resin, Rui monomer of the synthetic resin, a prepolymer, a precursor of such oligomers may be impregnated.

Since the corrugated cardboard of the present invention is usually molded into an interior material, it is desirable that the above-mentioned non-woven fabric be moldable. To allow the above-mentioned non-woven fabric to be molded, a thermoplastic fiber is contained or the above-mentioned synthetic resin or It is impregnated with a synthetic resin precursor or laminated with a thermoplastic synthetic resin sheet.

Further, the non-woven fabric may be colored or embossed, and if such a non-woven fabric is used as the surface material, the surface layer material becomes unnecessary.

The core material and the surface material are adhered to each other by using an ordinary adhesive, a hot-melt adhesive or the like. When a synthetic resin or a non-woven fabric impregnated with a synthetic resin precursor is used, the synthetic resin or the No need for an adhesive because the precursor functions as an adhesive.

The cardboard (11) is formed into a ceiling shape as shown in FIG. 2, for example, and is used as a ceiling material (14) for an automobile.

[0012]

[Effect of device]

 Therefore, the present invention provides an excellent interior material that is lightweight and has excellent moldability, and that is excellent in sound insulation and heat insulation and does not generate low-grade sound even when rubbed against the vehicle body.
