この考案は自動車のエンジンルーム内に設けら
れるインシユレーターに係わるものである。[Detailed Description of the Invention] (Industrial Application Field) This invention relates to an insulator installed in the engine room of an automobile.

られている。(Prior art and its problems) The molded product obtained by adding a binder to glass fiber and molding it has excellent heat resistance, sound absorption, heat insulation, processability, nonflammability, and lightness, and is used for automobiles. Those molded into a shape that can be attached to a panel inside the engine compartment are widely used as automobile insulators (hereinafter simply referred to as insulators).

著しく阻害する。 This insulator is installed on top of the car's engine or on the left or right side for the purpose of sound absorption and heat insulation, but since there is nothing underneath the engine to cover it, it is difficult to drive the car on rainy days. When rainwater splashes up or is blown up and scattered by a fan or the like, and if it splashes onto the surface or end face of the insulator, the water will penetrate into the inside of the insulator body, significantly impairing its sound absorption and heat insulation properties.

損なう。 In order to overcome these inconveniences, a waterproofing agent is applied to the surface of the molded insulator, or a skin material made of woven or non-woven fabric is applied to the surface of the insulator, and this is treated with waterproofing. However, rainwater adhering to the surface or skin material of the insulator is sucked up into the insulator, impairing its sound absorption and insulation properties.

This impairs heat and insulation properties.
（問題点を解決するための手段）
本考案は、インシユレーターを構成するガラス

である。(Means for solving the problem) The present invention involves attaching a water repellent to the surface of the glass fibers constituting the insulator, using the glass fibers that have undergone this treatment, and molding them into a mold of the desired shape. This method overcomes the above-mentioned disadvantages by being loaded and heat-molded.
次に本考案のインシユレーターを得る方法を説
明する。 Next, a method for obtaining the insulator of the present invention will be explained.
従来、インシユレーターを製造するには、ガラ

状となる一対の雌雄金型内に装填し、加圧、加熱
によつて未硬化の熱硬化性樹脂を硬化させて所望
形状の成形品としている。 Conventionally, in order to manufacture insulators, glass fibers are made by spraying an uncured thermosetting resin such as phenol resin or polyester resin (a curing agent may be added thereto). It is attached to fibers and loaded into a pair of male and female molds that form the desired insulator shape, and the uncured thermosetting resin is cured by pressurization and heating to form a molded product in the desired shape. .
本考案のインシユレーターを製造するには、上
記従来の製造方法に準じて行なうことができる。 The insulator of the present invention can be manufactured according to the conventional manufacturing method described above.
例えば、上記のような未硬化の熱硬化性樹脂

てガラス繊維表面を覆う。又は、ガラス繊維に対
し、上記のような撥水剤とバインダーとしての硬
化性樹脂とを別々に噴霧し、ガラス繊維に撥水性
を付与してもよい。 For example, a water repellent, preferably a water repellent with good heat resistance, is added to the uncured thermosetting resin as described above.
For example, a silicone resin, a fluororesin, or a paraffin-based water repellent is mixed, and this mixture is sprayed onto glass fibers to cover the surface of the glass fibers. Alternatively, water repellency may be imparted to the glass fibers by separately spraying a water repellent agent as described above and a curable resin as a binder onto the glass fibers.
以上のようにして撥水性を付与されたガラス繊
維は、従来法と同様にして金型内に装填し、加
熱、加圧して所望の形状に成形する。 The glass fibers imparted with water repellency as described above are loaded into a mold in the same manner as in the conventional method, heated and pressurized, and molded into a desired shape.
上記撥水剤の使用量は例えばガラス繊維１Kg当

100〜250ｇの範囲で使用される。具体的な１例を
示すと、撥水剤としてエマルジヨン型パラフイン
系撥水剤８ｇ、バインダーとしてフエノール樹脂
130ｇをガラス繊維１Kg当りに添加する。 The amount of the water repellent used may be, for example, in the range of 5 to 25 g per 1 kg of glass fiber. In addition, the thermosetting resin as a binder is, for example, per 1 kg of glass fiber.
Used in the range of 100-250g. To give a specific example, 8g of emulsion-type paraffin water repellent is used as a water repellent, and phenol resin is used as a binder.
Add 130g per kg of glass fiber.

で覆うようにしてもよい。 The insulator of the present invention may be formed by simply molding water-repellent glass fiber into a desired shape, or may be formed by covering one or both sides of such a molded product with a skin material. . Woven fabrics, non-woven fabrics, or metal foils such as aluminum foils are used as such skin materials. Woven fabrics and nonwoven fabrics are used by imparting water repellency with the above-mentioned water repellent.
When a metal foil is used and this foil covers the side of the insulator facing the engine side, it is preferable to use a metal foil with a large number of pores perforated over the entire surface of the insulator. When covering the side opposite the engine side, the foil may be perforated or non-perforated. As the skin material, one side of the insulator may be covered with a woven or nonwoven fabric, and the other side may be covered with metal foil.

共に良好に維持される。(Effect of the invention) In conventional insulators where the surface is waterproofed, water adhering to the surface penetrates into the interior through capillary action and is retained there, reducing the weight of the insulator itself. This not only increases the size of the insulator but also impairs its sound absorption and insulation properties, but in the case of the insulator of the present invention, the glass fibers that make up the insulator exhibit water repellency, so no water is retained inside the insulator. , and both sound absorption and insulation properties are maintained well.
