本発明は難燃性樹脂組成物、特に、耐熱性と耐衝撃性と
を有する難燃性ポリプロピレン系樹脂組成物に関する。DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a flame-retardant resin composition, particularly a flame-retardant polypropylene resin composition having heat resistance and impact resistance.

ゲン含有化合物の単価が高いという欠点もある。JP-A-55-30118 discloses a flame-retardant cable. There, compositions are used in which organic flame retardants such as phosphorus-containing compounds and halogen-containing compounds and inorganic flame retardants such as metal oxides are added to thermoplastic resins. In such systems, since low molecular weight compounds such as halogen-containing compounds are added, the resulting product suffers from a bleed-out phenomenon during long-term use. Furthermore, since a low molecular weight compound is added, there is a drawback that the heat distortion temperature is lowered. Furthermore, although it is possible to raise the ignition temperature of the composition, when heated, a resin sagging phenomenon occurs, making it impossible to achieve the flame retardant standard (UL-94) V-0. Another drawback is that the unit price of the halogen-containing compound is high.

充分に発揮され、耐熱性や難燃性が高まる。ざらに。The metal oxide is contained in a proportion of 5 to 20 parts by weight, preferably around 10 parts by weight, per 100 parts by weight of propylene-based 1-stem resin. Is the chlorine content of chlorinated polyethylene2?
The amount is 0 to 50% by weight, and by adding this, the substances constituting the composition, such as propylene resin, vinyl chloride resin, and metal oxide, are uniformly dispersed and mixed. As described above, since chlorinated polyethylene has the function of a dispersion aid, by adding it, the functions of the gold 1m oxide are fully exhibited, and heat resistance and flame retardance are improved. Roughly.
耐衝撃性も高まる。塩素化ポリエチレンはプロピレン系
樹脂１００重量部に対して５〜４０重量部。Impact resistance also increases. The amount of chlorinated polyethylene is 5 to 40 parts by weight per 100 parts by weight of propylene resin.

下するなど物性的に好ましくない。塩化ビニル系樹脂と
してはポリ塩化ビニル（ｐｖｃ）が好んで用いられる。If the amount is less than 5 parts by weight, the components in the composition will not be sufficiently dispersed and mixed, and if it is more than 40 parts by weight, the impact resistance will decrease, which is undesirable in terms of physical properties. Polyvinyl chloride (PVC) is preferably used as the vinyl chloride resin.
この塩化ビニル系樹脂はプロピレン系樹脂に混合される
とそのガラス転移温度までは一種の剛性向上のためのフ
ィラー的役割を果たし、剛性の同上や熱変形温度の向上
に寄与する。When this vinyl chloride resin is mixed with a propylene resin, it plays the role of a kind of filler for improving rigidity up to its glass transition temperature, and contributes to improving the same rigidity and heat distortion temperature.
例えばＰＶＣにおいてはそのガラス転移点が約８０℃で
ある。さらに高温度においても補強効果を必要とする場
合船こはガラス転移点温度が約１１０℃である塩素化塩
化ビニル（Ｃ−ＰＶＣ）が用いられる。For example, PVC has a glass transition point of about 80°C. Furthermore, when a reinforcing effect is required even at high temperatures, chlorinated vinyl chloride (C-PVC), which has a glass transition temperature of about 110° C., is used for ships.
このＣ−’ＰＶＣは分散性が悪く他の組成物との混合が
均一になされにくいためＰＶＣが分散助剤として用いら
れる。Ｃ−ＰＶＣとＰＶＣを５対１の割合で混合すると
熱変形温度が約１０℃高（なる。Since this C-'PVC has poor dispersibility and is difficult to mix uniformly with other compositions, PVC is used as a dispersion aid. When C-PVC and PVC are mixed at a ratio of 5:1, the heat distortion temperature increases by approximately 10°C.

同重量かそれ以下の割合で添加される。Additionally, inorganic fillers that enhance the rigidity and impact resistance of the composition include talc, mica, glass fiber, and the like. In particular, glass fiber has the effect of improving heat distortion temperature. Calcium carbonate, which is commonly used, is not preferred because it reduces flame retardancy. The above-mentioned inorganic filler is usually added in an amount equal to or less than the weight of the propylene resin.
