【０００１】[0001]
本考案は、軽量成形天井材に関し、詳細には軽量成形天井材自体の重量を軽減 し、更に激しい凹凸にも追従し得る、深絞り成形性及び吸音性にも優れた軽量成 形天井材に関する。 The present invention relates to a light-weight molded ceiling material, and more particularly to a light-weight molded ceiling material that reduces the weight of the light-weight molded ceiling material itself and can follow even severe irregularities and is also excellent in deep drawability and sound absorption. .

従来より、例えば、自動車用の天井材としては、フェルトを単独でもしくは接 着剤を介して不織布表皮材と一体化して加熱加圧成形してなる成形天井材が製造 されている。 BACKGROUND ART Conventionally, for example, as a ceiling material for automobiles, a molded ceiling material has been manufactured in which felt is singly or integrated with a non-woven fabric skin material through a bonding agent and heat-pressed.
【０００３】 しかしながら、フェルト単独の成形天井材では、深絞り成形性こそ優れるが、 吸音性、剛性共に満足な性能は得られず、接着剤を介して不織布表皮材と一体化 して用いた場合、天井材自体の重量が増加するという欠点があった。However, a molded ceiling material made of felt alone is excellent in deep-drawing moldability, but satisfactory performances in sound absorption and rigidity are not obtained, and when it is used integrally with a non-woven fabric skin material through an adhesive. However, there is a drawback that the weight of the ceiling material itself increases.
【０００４】[0004]
本考案の課題は、自動車重量の一層の軽量化を顕現すべく、成形天井材重量を 軽量化しつつ、吸音性、剛性にも優れ、更には優れた成形天井材の深絞り成形性 を実現する点にある。 The object of the present invention is to realize a further reduction in the weight of an automobile, while reducing the weight of the molded ceiling material, while also achieving excellent sound absorption and rigidity, and also achieving excellent deep drawing formability of the molded ceiling material. On the point.
【０００５】[0005]
かかる課題を解決せんとして、本考案者らは鋭意研究の結果、熱可塑性樹脂フ ィルムを吸音材の少なくとも片面と基材との間に設けたものであり、しかして本 考案の要旨は、以下に存する。 As a solution to this problem, the inventors of the present invention have conducted earnest research and found that a thermoplastic resin film was provided between at least one surface of the sound absorbing material and the base material. Therefore, the gist of the present invention is as follows. Exist in.
【０００６】 吸音層１の少なくとも片面に熱可塑性樹脂フィルム２を介して基材３を積層し 、該基材３はポリエステル樹脂繊維を芯材として周りにナイロン系樹脂繊維で覆 われている二層構造の合成樹脂繊維を主成分とする不織布であり、加圧成形によ り一体化してなることを特徴とする軽量成形天井材。A base material 3 is laminated on at least one surface of the sound absorbing layer 1 with a thermoplastic resin film 2 interposed therebetween, and the base material 3 is a two-layer structure in which a polyester resin fiber is used as a core material and is covered with a nylon resin fiber around it. A lightweight molded ceiling material, which is a non-woven fabric composed mainly of synthetic resin fibers with a structure, and is integrated by pressure molding.
【０００７】 吸音層１とは、嵩高性不織布、薄葉状不織布、フォーム材、熱可塑性フェルト （ポリプロピレン、ポリエチレン、ガラス繊維単独又は混合品）等でよく、例え ば嵩高性不織布の場合、動物性、植物性、合成樹脂性の不連続繊維材料の一種も しくは二種以上と熱硬化性樹脂等の結合剤を主体としてなるものであり、フォー ム材の場合、ポリスチレン、ポリプロピレン、ポリウレタン等が好ましい。また 、これらをハニカム板、ロールコア、フェザーコア等に充填した吸音層も剛性の 向上の点で好ましく使用できる。The sound absorbing layer 1 may be a bulky nonwoven fabric, a thin leaf-like nonwoven fabric, a foam material, a thermoplastic felt (polypropylene, polyethylene, glass fiber alone or a mixture) and the like. It is mainly composed of one or more kinds of discontinuous fiber materials of plant or synthetic resin and a binder such as thermosetting resin. In the case of foam material, polystyrene, polypropylene, polyurethane or the like is preferable. . Also, a sound absorbing layer in which these are filled in a honeycomb plate, a roll core, a feather core, or the like can be preferably used in terms of improving rigidity.
【０００８】 熱可塑性樹脂フィルム２とは、ポリエステル、ポリプロピレン、ポリエチレン 、塩化ビニル、酢酸ビニル等の熱可塑性樹脂のポリマー、エチレン−酢酸ビニル 等のコポリマーを原料としたフィルムである。フィルムを加熱溶融することによ り吸音層１と基材３との両方の繊維成分内部に浸透し、アンカー効果により両者 を一体化される。従って使用する熱可塑性樹脂は、天井を加熱加圧成形する時の 温度を考慮して、加熱温度以下の融点を有するものを選択することが必要である 。The thermoplastic resin film 2 is a film made of a polymer of a thermoplastic resin such as polyester, polypropylene, polyethylene, vinyl chloride or vinyl acetate, or a copolymer of ethylene-vinyl acetate. By heating and melting the film, it penetrates into the fiber components of both the sound absorbing layer 1 and the base material 3, and the two are integrated by the anchor effect. Therefore, it is necessary to select a thermoplastic resin having a melting point equal to or lower than the heating temperature in consideration of the temperature when the ceiling is heated and pressed.
【０００９】 基材３とは、ポリエステル樹脂を原料とする繊維を芯材とし該芯材を覆う様に ナイロン系樹脂、好ましくは６−ナイロン樹脂によるスキン層を有する２層構造 の合成繊維による不織布である。基材は、形状保持性、表面補強の機能を併せて 有するものが好ましい。The base material 3 is a synthetic fiber non-woven fabric having a two-layer structure in which a fiber made of a polyester resin is used as a core material and a skin layer made of a nylon resin, preferably 6-nylon resin, is provided so as to cover the core material. Is. It is preferable that the base material has the functions of shape retention and surface reinforcement.
【００１０】 表皮層を使用する場合、表面補強の機能を併せて有するものが良く、ガラスペ ーパー、ガラスマット、紙、薄葉状不織布等が例示できる。When the skin layer is used, it is preferable that it also has a surface reinforcing function, and examples thereof include glass paper, glass mat, paper, and thin-leaf nonwoven fabric.
【００１１】 表皮層を使用する場合の基材３と表皮層の接着は、必要に応じてホットメルト 又は塗布型接着剤を用いて行なう。When the skin layer is used, the base material 3 and the skin layer are adhered to each other by using a hot melt or a coating adhesive, if necessary.
【００１２】 かかる各構成材料を一体成形する方法としては、例えば、吸音層の一方の面に 熱可塑性樹脂フィルムを介して基材を積層し、他方の面には同様に熱可塑性樹脂 フィルムを介して基材を積層して吸音層を挾置した場合、自動車用成形天井を製 造しようとする時には任意形状の金型上に載置し、金型を降下接合させて加熱加 圧成形を行なう。温度、圧力条件の一例としては、１５０〜２４０℃で２０秒〜 ２分間、１〜２００ｋｇ／ｃｍ2 の条件が好ましい。また、任意の方法により熱 可塑性フィルムを溶解するに充分なプレヒートが行えれば、コールドプレスによ り成形することも可能である。As a method of integrally molding each of the constituent materials, for example, a base material is laminated on one surface of the sound absorbing layer with a thermoplastic resin film, and the other surface is similarly laminated with a thermoplastic resin film. When a base material is laminated and a sound absorbing layer is placed, when a molded ceiling for automobiles is to be manufactured, it is placed on a mold of arbitrary shape and the mold is lowered and joined to perform heat-press molding. . As an example of temperature and pressure conditions, conditions of 150 to 240 ° C. for 20 seconds to 2 minutes and 1 to 200 kg / cm 2 are preferable. Also, if preheating sufficient to dissolve the thermoplastic film can be performed by an arbitrary method, it can be molded by cold pressing.
