できるものではなかった。Looking at conventional molded ceiling materials, there are a wide variety of products molded from organic and inorganic fibers, such as waste felt (organic) and glass wool (inorganic), as well as other products such as dead balls, styrene, and the above-mentioned bonded products. However, none of them were definitively superior in terms of their advantages and disadvantages, and the product weight was 80.
It was very heavy at 0 g/n (~1 kg/m) and was not satisfactory.
本発明は従来品の欠点であった重量の軽量化を可能にす
るとともに、吸音性能と外部よりの断熱性能にも優れた
自動車用成形天井材を提供しようとするものである。The present invention aims to provide a molded ceiling material for automobiles that can reduce the weight, which has been a drawback of conventional products, and also has excellent sound absorption performance and external insulation performance.
本発明は繊維質基材の使用量をできるだけσ凝らして、
軽量化を図り、その強度減少分を基材に張り合わせたア
ルミ箔で補うとともに、吸音性能と外部よりの断熱性能
も一挙に改良するものである。In the present invention, the amount of the fibrous base material to be used is increased as much as possible,
The aim is to reduce the weight, compensate for the loss in strength with aluminum foil laminated to the base material, and simultaneously improve sound absorption performance and insulation performance from the outside.
繊維質基材としては、グラスウール板、屑フェルト板、
ダンボール紙等が用いられる。その目付重量は３００〜
５５０ ｇ／ｍで、これより軽くすると、製品の強度が
不十分となり、また、これより重くすると、製品重量が
重くなってしまい、好ましくない。また、基材の密度は
、３０〜１１０ｋｇ／ｒｒ？′のものが好ましい。また
、材質としては燃焼性、加工性の点から、グラスウール
板が好ましい。Fibrous base materials include glass wool board, scrap felt board,
Cardboard paper or the like is used. Its basis weight is 300~
The weight is 550 g/m, and if it is lighter than this, the strength of the product will be insufficient, and if it is heavier than this, the weight of the product will be undesirable. Also, the density of the base material is 30 to 110 kg/rr? ' is preferred. Further, as the material, a glass wool plate is preferable from the viewpoint of combustibility and processability.
アルミ箔は５〜５０μの薄いものが用いられる。A thin aluminum foil of 5 to 50 μm is used.
好ましくは７〜２０μのものがよく、薄過ぎると、強度
が不十分となり、厚過ぎると吸音効果が悪くなる。Preferably, the thickness is 7 to 20 μm; if it is too thin, the strength will be insufficient, and if it is too thick, the sound absorption effect will be poor.
本発明において、アルミ箔と反対側の基材面に、必要に
応じ基材とは異なる他の繊維補強材を貼り合わすことが
、強度の点からみて好ましい。In the present invention, from the viewpoint of strength, it is preferable to bond another fiber reinforcing material different from the base material to the base material surface opposite to the aluminum foil, if necessary.
繊維補強材としては、ビニロン、ポリエステル、スフ等
の寒冷紗、ガラス、ポリエステル等の不織布、グラスウ
ールペーパー、ダンボール紙が用いられる。重量、補強
効果の点から、目付重量３０〜１２０ｇ／ｍの寒冷紗が
好ましい。As the fiber reinforcing material, cheesecloth such as vinylon, polyester, and cotton cloth, glass, nonwoven fabrics such as polyester, glass wool paper, and cardboard paper are used. From the viewpoint of weight and reinforcing effect, cheesecloth having a basis weight of 30 to 120 g/m is preferable.
そして、基材と、アルミ箔、繊維補強材は熱硬化性樹脂

箔の場合は接着剤を用いなくても貼り合わせることがで
きる。The base material, aluminum foil, and fiber reinforcing material are then bonded together using thermosetting resin, such as phenol resin, melamine resin, urea resin, polyester resin, etc., and shaped into a predetermined shape similar to the inside shape of an automobile roof. Pressure molded. Then, a facing material is pasted together as required. Note that in the case of aluminum foil, it can be bonded together without using an adhesive.
以下、本発明を実施例に基づいて詳細に説明する。 Hereinafter, the present invention will be explained in detail based on examples.
