る。In recent years, a base material made of polystyrene foam has been adopted as a molded ceiling material for automobiles because of its light weight and good moldability. As shown in FIG. 4, the base material 24 is made of polystyrene foam. The one in which the rigidity is improved by sandwiching the foam layer 23 with a skin layer 22 made of a polystyrene resin film is used. However, since such a base material is flammable, a molded ceiling material having improved flame retardancy has been developed. As such a flame-retardant molded ceiling material, for example, a non-woven fabric impregnated with a binder composed of ethylene-vinyl chloride emulsion and a flame retardant in a polystyrene-based foam having polystyrene-based resin film adhered to both surfaces is formed by a hot melt film. A flame-retardant non-woven molded ceiling material formed by adhesive molding is proposed in Japanese Patent Application No. 61-295435.

る。As shown in FIG. 7, when mounting a molded ceiling material in which a skin material made of a non-woven fabric impregnated with a flame retardant material is laminated on the above-mentioned base material to an automobile, the opening trim 21a and the molded ceiling material 26 are separated from each other. In order to hide it, we are using the side rail garnish 27 which is the side trim.
See No. 456). In the figure, 20 is a vehicle roof material and 25 is a skin material.

る。Recently, there has been a demand for a side trimless structure in the molded ceiling material from the viewpoint of designability and reduction of parts. As a method of not using the side trim, a method of winding the molded ceiling material around the body end portion is considered. This method is a mounting method that has been conventionally used in a suspended ceiling, but since a molded ceiling material using a polystyrene foam base material has a large wall thickness, it is difficult to wind the mounting portion.

一体プレス成形することを特徴とするものである。The method for producing a flame-retardant interior material of the present invention is a nonwoven fabric composed of glass fibers and synthetic fibers, impregnated with a resin in an emulsion state in which at least 150 parts by weight of an inorganic flame retardant is added to 100 parts by weight of a resin content. After that, the dried impregnated non-woven fabric is laminated on both sides of a polystyrene foam as a base material, the base material is preheated, laminated with a skin material, and both are integrally press-molded. is there.
本発明に用いる合成繊維としては、例えばポリエステル
繊維、ポリ塩化ビニル繊維、ポリ塩化ビニリデン繊維、
ポリアミド繊維、ポリエチレン繊維、ポリプロピレン繊
維などが挙げられる。Examples of the synthetic fiber used in the present invention include polyester fiber, polyvinyl chloride fiber, polyvinylidene chloride fiber,
Examples thereof include polyamide fiber, polyethylene fiber, polypropylene fiber and the like.
ガラス繊維と合成繊維の割合は剛性及び難燃性の点から
ガラス繊維が少なくとも40重量％以上であることが好ま
しく、柔軟性の点からは合成繊維が少なくとも20重量％
以上であることが好ましい。The ratio of glass fiber to synthetic fiber is preferably at least 40% by weight or more from the viewpoint of rigidity and flame retardancy, and at least 20% by weight of synthetic fiber from the viewpoint of flexibility.
The above is preferable.
不織布化法としては慣用の方法を用いることができ、例
えば繊維接着法、抄造法などが挙げられる。As a method for forming a non-woven fabric, a conventional method can be used, and examples thereof include a fiber bonding method and a papermaking method.
不織布に含浸する無機質系難燃剤としては水酸化マグネ
シウム、水酸化アルミニウム、酸化モリブデン、三酸化
アンチモン、酸化ジルコニウム、酸化ケイ素、ホウ酸塩
等を用いる。ただし、無機質系難燃剤の割合が多過ぎる
と含浸した不織布を曲げたとき割れが生じるので、300
重量部以下、好ましくは200重量部以下とするとよい。Magnesium hydroxide, aluminum hydroxide, molybdenum oxide, antimony trioxide, zirconium oxide, silicon oxide, borate or the like is used as the inorganic flame retardant impregnated into the nonwoven fabric. However, if the proportion of the inorganic flame retardant is too high, cracking will occur when the impregnated nonwoven fabric is bent, so 300
It is good to set it as below weight part, preferably below 200 weight part.
表皮材としてはフアブリツク又は塩化ビニルフイルム
と、ポリウレタンフオームとを積層したものが好ましい
が、慣用の他の表皮材も用いることができる。As the skin material, a laminate of a fabric or vinyl chloride film and a polyurethane film is preferable, but other commonly used skin materials can also be used.

難燃性内装材料が得られる。By using a non-woven fabric composed of glass fiber and synthetic fiber, the glass fiber gives rigidity and flame retardancy to the interior material,
Synthetic fibers give moderate flexibility. The resin content in the nonwoven fabric
After impregnating the resin in the emulsion state in which at least 150 parts by weight of the inorganic flame retardant is added to 100 parts by weight, the resin is dried to fix the inorganic flame retardant to the nonwoven fabric, causing it to crack or the like. It is possible to bend without making the inorganic flame retardant render the nonwoven fabric flame-retardant. Then, the nonwoven fabric is laminated on both sides of a polystyrene-based foam to form a base material, whereby the polystyrene-based foam imparts rigidity to the base material, and the nonwoven fabric makes the base material flame-retardant due to its own flame retardancy. Next, when the base material is preheated, the polystyrene-based foam is softened and is in a state of being easily molded. By integrally press-molding the base material and the skin material in this state, both are integrated and molded,
A flame-retardant interior material is obtained.

I clipped 2 In the figure, 3a indicates a stripped base material. Next, the skin material 3 is attached to the vehicle body roofing material 20, the skin material 6 at the end portion and the polystyrene-impregnated non-woven fabric 2 are wound around the flange fitting portion of the vehicle body roofing material 20, and then the opening trim 21 is attached to the flange fitting portion. Cover
The end of the molded ceiling material 7 was locked to the flange fitting portion of the vehicle body roof material 20. The polystyrene-impregnated non-woven fabric 2 carries aluminum hydroxide, but no cracks were caused by bending when the flange-engaging portion was rolled up. Further, since the polystyrene-impregnated nonwoven fabric 2 has flame retardancy by itself and is also rigid, it does not sag and does not use side trim, and the molded ceiling material is kept in a flame retardant state. I was able to install it.
