【産業上の利用分野】
自動車用フードインシュレーターに関する。更に詳細には、吸音性、成形性、意匠性、などに優れる自動車用フードインシュレーターに関する。
【０００２】
【従来の技術】
現在、フェノール樹脂などのバインダー樹脂を付着させたガラス繊維マットの少なくとも片面に不織布を積層させ一体成形して成るフードインシュレーターがある。
フードインシュレーターは、カバリング性を高める為には、表面層の不織布の繊維量を多くする、構成繊維径を細くするおよび緻密構成にすることなどが必要である。
【０００３】
不織布の構成繊維量を増やすことによりカバリング性、意匠性を向上させることはできるが加熱プレスによる成形加工時に構成繊維相互の伸長、ズレなどが難しく、成形加工性が悪くなり、且つ、コスト高となり経済的負担となるという問題がある。
【０００４】
【発明が解決しようとする課題】
本発明の目的は、フードインシュレーターのカバリング性が改善され、意匠性が高められ、且つ、吸音性、成形加工性が優れたフードインシュレーターを提供することにある。

【００１０】
本発明に用いるガラス繊維マットは、熱成形加工ができ、得られた製品が剛性を有し保形性に優れ、且つ、自動車用部品である為、難燃性を有することが必要である。
本発明に用いるガラス繊維マットは、フェノール樹脂が付着したもので、付着量は１０〜１００重量％であることが好ましく、さらに好ましくは２０〜８０重量％である。フェノール樹脂が付着していると、熱成形加工時の加熱温度、例えば１５０℃〜２５０℃、でガラス繊維相互の接着及び硬化させることができる。
【００１１】
フェノール樹脂付着量が１０重量％以下では、接着及び硬化が不足し、目的とする、剛性及び保形性が得られない。一方、１００重量％以上では剛性及び保形性が十分得られるがフェノール樹脂付与方法、コストなどに問題が生じる。
ガラス繊維マットの目付は２００〜１５００ｇ／ｍ２ が好ましく、さらに好ましくは３００〜１０００ｇ／ｍ２ である。
【００１２】

[Industrial application fields]
The present invention relates to automobile food insulators. More specifically, the present invention relates to a hood insulator for automobiles that is excellent in sound absorption, moldability, designability, and the like.
[0002]
[Prior art]
Currently, there is a hood insulator in which a nonwoven fabric is laminated and integrally formed on at least one surface of a glass fiber mat to which a binder resin such as a phenol resin is attached.
In order to improve the covering property of the food insulator, it is necessary to increase the fiber amount of the nonwoven fabric of the surface layer, to narrow the constituent fiber diameter, and to form a dense structure.
[0003]
The covering and design properties can be improved by increasing the amount of the constituent fibers of the nonwoven fabric, but it is difficult to stretch and shift the constituent fibers at the time of molding processing with a hot press, resulting in poor molding processability and high cost. There is a problem that it becomes an economic burden.

The constituent fiber of the synthetic long fiber nonwoven fabric used in the present invention is not particularly limited as long as it satisfies the object of molding processability. For example, polyethylene fiber, polypropylene fiber, polyamide fiber, polyester fiber, polyethylene-polyester, copolymer polyester-polyester, etc. A single fiber or a long fiber composed of two or more kinds, such as a composite fiber, can be used. In particular, it is preferable that the fibers constituting the nonwoven fabric be synthetic long-fiber nonwoven fabrics such as crimped fibers and unstretched fibers because the 10% intermediate stress at a molding temperature of 150 ° C. can be lowered.
[0008]
The shape of the fiber is not particularly limited, but a round shape, an irregular cross section, or a crimped fiber is used.
If the intermediate stress at the heating temperature at the time of molding is low, it can be easily stretched with a smaller force, can be easily shaped, and can be easily thermoformed into a largely deformed uneven shape.
The synthetic long fiber nonwoven fabric used in the present invention has a 10% intermediate stress of 5 kg / 5 cm or less, preferably 3 kg / 5 cm or less at a temperature of 150 to 250 ° C. The breaking elongation is preferably 30% or more, and more preferably 50% or more.
[0009]
The synthetic fiber long-fiber nonwoven fabric used in the present invention has a basis weight of 50 g / m 2 or less, preferably 20 to 40 g / m 2 . If the basis weight is 50 g / m 2 or more, it is difficult for the constituent fibers to be stretched or displaced, and the moldability becomes insufficient. The method for producing the synthetic long fiber nonwoven fabric used in the present invention can be obtained by a single or a combination of two or more of known spunbond method, needle punch method, thermal bond method and the like. In particular, a synthetic long-fiber nonwoven fabric made of partial thermocompression bonding or a needle-punched nonwoven fabric of a synthetic long-fiber nonwoven fabric is preferable.
[0010]
The glass fiber mat used in the present invention is capable of thermoforming, and the obtained product is rigid and excellent in shape retention, and is a component for automobiles. Therefore, it is necessary to have flame retardancy.
The glass fiber mat used in the present invention has a phenol resin attached thereto, and the attached amount is preferably 10 to 100% by weight, and more preferably 20 to 80% by weight. When the phenol resin is adhered, the glass fibers can be bonded and cured at a heating temperature during thermoforming, for example, 150 ° C. to 250 ° C.
[0011]
When the phenol resin adhesion amount is 10% by weight or less, adhesion and curing are insufficient, and the desired rigidity and shape retention cannot be obtained. On the other hand, when the content is 100% by weight or more, rigidity and shape retention are sufficiently obtained, but problems arise in the phenol resin application method, cost, and the like.
Basis weight of the glass fiber mat is preferably 200~1500g / m 2, more preferably from 300~1000g / m 2.
[0012]
The glass fiber mat used in the present invention may be mixed with other fibers as long as the objectives of the present invention are thermoformability, rigidity, shape retention and the like.
The method for adhering the phenolic resin to the glass fiber mat used in the present invention is a known method, for example, impregnating with an aqueous or solvent-based phenolic resin solution or spraying.
[0013]
Although the synthetic resin film used for this invention is not specifically limited, For example, it is single or 2 or more types of composite films, such as polyethylene, a polypropylene, polyamide, polyester.
The synthetic resin film used in the present invention preferably has a thickness of 10 μ to 100 μ, more preferably 20 μ to 60 μ.
[0014]
The synthetic resin film used in the present invention is interposed between the glass fiber mat and the nonwoven fabric to prevent glass fiber scattering and skin acupuncture.
The synthetic resin film used in the present invention can be bonded to a nonwoven fabric or a glass fiber mat in the previous step. For example, extrusion lamination, adhesive lamination, heat welding lamination, and the like.
[0015]
In the method for producing a food insulator of the present invention, after laminating the above materials, the concavo-convex mold is heated to a temperature of 150 ° C. to 250 ° C., and is heated and press-molded for several tens of seconds to several minutes to obtain a desired shape. obtain.
The nonwoven fabric and synthetic resin film used in the present invention are preferably colored in similar colors in order to improve the appearance quality of the nonwoven fabric forming the surface layer, and are excellent in covering properties and design properties.
[0016]
The food insulator of the present invention does not have a tingling property such as a glass fiber tingling when touched by a hand, and has an excellent covering property such that a part of the glass fiber mat is hardly seen from the surface.
Since the specific nonwoven fabric forms the surface layer in the food insulator of the present invention, the covering property is good, the design property is excellent, and the food insulator can be sufficiently deformed at the time of molding by a hot press.
[0017]

(2) As the synthetic resin film, a low-density polyethylene film having a thickness of 25 μm and black-colored by adding a carbon pigment was used.
(3) A glass fiber mat having a weight per unit area of 650 g / m 2 and a thickness of 25 mm to which 30% by weight of phenol resin was adhered was used.
[0019]
(1) Nonwoven fabric, (2) Synthetic resin film, (3) Glass fiber mat, and (1) Nonwoven fabric are stacked in this order and heated and pressed with a molding machine heated to a temperature of 235 ° C. Press molding was performed to obtain a food insulator.
The moldability was good without tearing or floating.
As for the designability, the glass fiber interposed therein was not visible from the surface, and the covering property and the appearance quality were good.
[0020]
Sound absorptivity is effective, especially in the high frequency region.
As described above, the automotive hood insulator of the present invention has obtained results that sufficiently satisfy the objects such as moldability, designability, and sound absorption.
[0021]
[Comparative Example 1]
(1) As the nonwoven fabric, a polyester continuous fiber nonwoven fabric having a basis weight of 70 g / m 2 , an average fiber diameter of 1.8 denier, a 10% intermediate stress at 150 ° C. of 8.5 kg / 5 cm and a partial thermocompression bonding rate of 25% was used. .

[0022]
(1) Nonwoven fabric, (2) Glass fiber mat, and (1) Heat and pressure press molding was carried out in the same manner as in Example 1 by overlapping with the nonwoven fabric.
The moldability was poor in the ability to follow the concavo-convex mold, and a floating part was generated, and the intended shape could not be obtained.
As for the design property, the covering property that the glass fiber interposed therein is hardly visible is good, but the shape is bad (the moldability is bad), and a satisfactory result cannot be obtained.
[0023]
As for sound absorption, compared with Example 1, a good result was not obtained.
As described above, the moldability is insufficient and the design property is poor.
[0024]
【The invention's effect】
The automobile hood insulator of the present invention is excellent in moldability, surface design, and sound absorption compared to conventional ones.
Therefore, it can be suitably used as a sound-absorbing material such as an engine room for automobiles and the back of a hood, and a heat insulating material.
