Description
【0001】[0001]
本考案は、自動車の吸音性能が求められる部位に装着してなる自動車用成形防 音材に関し、特にはエンジンルーム内に装着して、エンジン音に起因する車外騒 音及び車室内騒音を満足に防止した自動車用成形防音材に関する。 The present invention relates to a molded sound insulation material for automobiles, which is mounted on a portion of a vehicle where sound absorption performance is required, and is particularly mounted in the engine room to satisfy the noise outside the vehicle and the noise inside the vehicle caused by the engine noise. The present invention relates to a molded soundproof material for automobiles.

従来より、例えば、自動車のエンジンルーム内用防音材としては、繊維質もし くはフォーム材基材と撥水性、撥油性を有する表皮とを成形一体化した防音材が 提案されている。 Conventionally, for example, as a soundproof material for an automobile engine room, a soundproof material in which a fibrous or foam base material and a water-repellent and oil-repellent skin are integrally molded has been proposed.
【0003】 かかる成形防音材でもある程度の吸音効果はあるものの車外、車室内への騒音 低減のニーズが高まり、より一層の吸音性能の向上が求められていた。また、防 音材基材の膜振動を応用した吸音機能をも併せ持ち、特に自動車エンジンルーム 内の優れた吸音性能を得ようという思想は従来にはなかった。Although such a molded soundproof material has some sound absorbing effect, there is an increasing need for noise reduction outside and inside the vehicle, and further improvement in sound absorbing performance has been demanded. In addition, it also has a sound absorption function that applies the film vibration of the soundproofing material base material, and there has been no idea in the past to obtain excellent sound absorption performance especially in the automobile engine room.
【0004】[0004]
本考案の課題は、軽量でありながら従来品をしのぐ強度を有し、かつ一段と吸 音性能に優れた防音材を実現する点にある。 An object of the present invention is to realize a soundproof material which is light in weight, has strength superior to that of conventional products, and is further excellent in sound absorbing performance.
【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、張出し部を有し 、かつ膜振動しうる防音材基材を使用し、網目状物との組合せにより上記課題を 解決できることを知見したものであり、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 as a result of earnest research and found that the above problem can be solved by using a soundproof material base material having an overhang portion and capable of vibrating a membrane, and combining it with a mesh-like material. However, the gist of the present invention lies below.
【0006】 張出し部3を有する防音材基材1の裏面側に距離を設けて網目状物2を一体化 せしめてなることを特徴とする自動車用成形防音材。A molded soundproof material for automobiles, characterized in that the mesh material 2 is integrated by providing a distance on the back surface side of the soundproof material base material 1 having the overhang portion 3.
【0007】 張出し部3を有する防音材基材1の裏面側に距離を設けて網目状物2を一体化 せしめ、該張出し部の裏面側には吸音材4を充填してなることを特徴とする自動 車用成形防音材。The soundproof material substrate 1 having the overhanging portion 3 is provided with a distance on the back surface side to integrate the mesh-like material 2, and the back surface side of the overhanging portion is filled with the sound absorbing material 4. Molded soundproof material for automobiles.
【0008】 防音材基材1は、薄葉状の基材であることが好ましく、ポリウレタン、ポリエ チレン、ポリプロピレン、ポリ塩化ビニル、ポリカーボネート等からなる薄いフ ォーム材やフィルム、またフェルト、不織布、ガラスウール等の薄い繊維質物を 使用することができる。具体的には、1〜5mm程度の厚みで、1m2当り、5 0〜300g程度の重量のものの使用が好ましい。1mm未満、50g未満では 、防音性能に劣る場合があり、5mm、300gを超えるものは、重量増となる 。The soundproofing material base material 1 is preferably a thin leaf-shaped base material, and is a thin foam material or film made of polyurethane, polyethylene, polypropylene, polyvinyl chloride, polycarbonate, etc., or felt, nonwoven fabric, glass wool. It is possible to use thin fibrous materials such as. Specifically, it is preferable to use one having a thickness of about 1 to 5 mm and a weight of about 50 to 300 g per 1 m 2 . If it is less than 1 mm or less than 50 g, the soundproofing performance may be inferior, and if it exceeds 5 mm or 300 g, the weight may increase.
【0009】 かかる防音材基材1は、成形に際して張出し部3を設けることを必須とし、該 張出し部により成形防音材の表面積を増大し、吸音性能を向上せしめる。隣接す る2つの張出し部間の距離、張出し部の高さは、使用する基材の材質、重量等に より適宜変更し、張出し部間の距離は、5〜200mmの間で最良の防音効果を 求めるよう設定するのが好ましい。5mm未満の場合、低周波数領域での吸音性 に劣り、200mmを超える場合、逆に高周波数領域での吸音性に劣る場合があ る。張出し部の高さは、1mm以上が好ましく、張出し部を有することが吸音性 を含む防音効果の向上のために重要なことである。In the soundproof material base material 1, it is indispensable to provide the overhanging portion 3 at the time of molding, and the overhanging portion increases the surface area of the molded soundproofing material and improves the sound absorbing performance. The distance between two adjacent overhanging parts and the height of the overhanging part should be changed appropriately according to the material and weight of the base material used, and the distance between the overhanging parts should be between 5 and 200 mm for the best soundproofing effect. It is preferable to set so that If it is less than 5 mm, the sound absorption property in the low frequency range may be poor, and if it exceeds 200 mm, the sound absorption property in the high frequency range may be poor. The height of the overhanging portion is preferably 1 mm or more, and it is important to have the overhanging portion in order to improve the soundproof effect including the sound absorbing property.
【0010】 本考案は、防音材基材1の裏面側に網目状物2を一体化せしめてなるものであ り、該網目状物2は、主として、防音材基材1を補強する目的を有し、プラスチ ック製ネットや金網の使用が好ましい。The present invention is one in which a mesh 2 is integrally formed on the back surface side of a soundproof material base 1, and the mesh 2 is mainly intended to reinforce the soundproof material base 1. Therefore, it is preferable to use a plastic net or a wire net.
【0011】 張出し部裏面に吸音材4を充填してなることは、吸音効果の一層の向上のため に好ましく、解繊繊維や動植物性繊維材料からなる繊維質材料、ポリウレタン、 ポリエチレン、ポリプロピレン、ポリ塩化ビニル、ポリカーボネート等からなる フォーム材が使用できる。It is preferable that the back surface of the overhanging portion is filled with a sound absorbing material 4 in order to further improve the sound absorbing effect. Foam materials such as vinyl chloride and polycarbonate can be used.
【0012】 本考案になる防音材は、自動車への装着に際しては、特にエンジンルーム内で の装着使用が好ましく、吸音性能を求める天井部位に装着しても良い。The soundproofing material according to the present invention is preferably mounted and used in an engine room when it is mounted on an automobile, and may be mounted on a ceiling portion where sound absorption performance is required.
【0013】 本考案になる防音材を製造する方法としては、例えば、繊維製基材の成形後、 その裏面に該繊維製基材と比べ張出し部の高さを低く成形したプラスチック製ネ ットを積層、圧着したり、発泡成形型にフォーム材原液を注入、発泡せしめた後 、同じく張出し部の高さを低く成形したネットを圧着して得ることができる。As a method of manufacturing the soundproofing material according to the present invention, for example, after molding a fiber base material, a plastic net formed on the back surface of the base material is formed such that the height of the overhanging portion is lower than that of the fiber base material. Can be obtained by laminating and press-bonding, or by pouring a foam material stock solution into a foaming mold to foam it, and then press-bonding a net similarly shaped with a low overhang.
【0014】 特にエンジンルーム内用吸音材として、ダッシュアウター、エンジンアンダー カバーとして装着する場合、防音材表面に撥水、撥油処理を施しておくことは好 ましい。In particular, when the dash outer or the engine under cover is mounted as a sound absorbing material for the engine room, it is preferable to apply water repellency or oil repellency treatment to the surface of the sound proof material.
