〔産業上の利用分野〕
この発明は、自動車や家屋などに用いる内装材に関し、
さらに詳述するならば、内装材の暴利に添加する難燃剤
に関するものである。[Detailed Description of the Invention] [Industrial Application Field] This invention relates to interior materials used for automobiles, houses, etc.
More specifically, it relates to flame retardants added to interior materials.
一般に、自動車や家屋に用いる内装材には、難燃性を確

Typical flame retardants that have been used conventionally include compounds containing phosphorus, antimony, chlorine, and bromine, and substances containing water of crystallization such as aluminum hydroxide.
しかしながら、このような公知の難燃剤を添加した内装

■ 公知の難燃剤は、この種の内装材において一般的な

■ 公知の難燃斉旺はしばしば燃焼時に人体に有害なガ

■ 公知の難燃剤の中には、前記の■〜■のすべての問
題すべてについて、同時に解決できるものがない。(2) Among the known flame retardants, there is no one that can simultaneously solve all of the problems (1) to (3) above.
本発明は、前記のような公知の難燃剤がもつ前記の■−
■のすべての問題を克服しつつ、同時に必要な難燃性を
もった内装材を提供する。The present invention provides the above-mentioned
To provide an interior material that overcomes all of the problems mentioned above and at the same time has the necessary flame retardancy.
課題を解決するための本発明の手段は、従来、内装材中
に添加してきた公知の難燃剤に代えて、熱膨張性黒鉛を
、樹脂基材層に添加することによる。The means of the present invention for solving the problem is to add thermally expandable graphite to the resin base material layer instead of the known flame retardant that has conventionally been added to interior materials.
本発明にて、難燃剤として用いる熱膨張性黒鉛は、温度
が２００°Ｃ以下では物理的にも化学的にも安定である
が、温度が２００°Ｃをこえると、体積が約２００倍に
急激に発泡するという特異な性質をもっている。The thermally expandable graphite used as a flame retardant in the present invention is physically and chemically stable at temperatures below 200°C, but when the temperature exceeds 200°C, the volume increases approximately 200 times. It has the unique property of rapidly foaming.
本発明は、熱膨張性黒鉛のこのような温度依存性を利用
して、せいぜい１５０°Ｃ以下であるこの種の内装材の
成形温度や、せいぜい１１０°Ｃ以下である耐熱要求温
度においては、何ら物理的または化学的変化をおこすこ
とがなく、（したがって内装材の品質の劣化をひぎおこ
すことがない）−方、燃焼状態において受けるであろう
数千℃の温度条件下においては、すみやかに発泡・膨張
し炎を完全に速断して、燃焼を終結させる（あるいは着
火を阻止する）という理想的な難燃特性をもつ内装材を
得るものである。The present invention makes use of such temperature dependence of thermally expandable graphite, and at the molding temperature of this type of interior material, which is at most 150°C or lower, and the required heat resistance temperature, which is at most 110°C or lower, It does not cause any physical or chemical changes (therefore, it does not cause any deterioration in the quality of the interior material), but it does not react quickly under the temperature conditions of several thousand degrees Celsius that would be experienced in combustion conditions. The objective is to obtain an interior material with ideal flame-retardant properties that foams and expands, completely extinguishes flames, and terminates combustion (or prevents ignition).
また先述したように、熱膨張性黒鉛は、化学的にも不活
性であり、基材樹脂中に添加されている他の添加物に、
何ら悪影響を与えることもなく、また他の添加剤に影響
されることもない。In addition, as mentioned earlier, thermally expandable graphite is chemically inert and does not interact with other additives added to the base resin.
It has no adverse effects and is not affected by other additives.
さらに、本発明にて用いる熱膨張性黒鉛は、その約９０
％が固定炭素であり、したがって、たとえ、強烈な火炎
によって内装材が強制的に燃焼させられたとしても、有
害なガスを発生することもない。Furthermore, the thermally expandable graphite used in the present invention has approximately 90%
% is fixed carbon, so even if the interior material is forced to burn with an intense flame, no harmful gases will be emitted.
以下に本発明の実施例について説明するが、これは発明
の内容を限定するものではない。Examples of the present invention will be described below, but these are not intended to limit the content of the invention.
なお、燃焼性の評価については、ＦＭＶＳＳ（米国自動
車安全基準）ＮＯ，３０２にしたがっておこなった。The evaluation of flammability was conducted in accordance with FMVSS (American Motor Vehicle Safety Standard) No. 302.
