[Means for Solving the Problems]
The vinyl chloride-based resin rehabilitation pipe according to the invention of claim 1 (hereinafter referred to as “the present invention 1”) is a rehabilitation pipe that is inserted into an existing pipe and is brought into close contact with the inner surface of the existing pipe by being heated. And 100% by weight of an acrylic monomer component containing 50% by weight or more of an alkyl (meth) acrylate monomer having a glass transition temperature of -140 to -20 ° C of a homopolymer and 50% by weight or less of another acrylic monomer. Parts and more than 10% by weight of an acrylic copolymer obtained by copolymerizing 0.01 to 30 parts by weight of a polyfunctional monomer component and 40% by weight or less, and 90% by weight of a vinyl chloride monomer or a vinyl chloride monomer and other copolymerizable monomers. Less than 60% by weight or more is graft copolymerized, and 100 parts by weight of the composite vinyl chloride resin having an average degree of polymerization of 400 to 2500 is added to the composite vinyl chloride resin. Characterized in that it is obtained a thermoplastic elastomer 3 to 30 parts by weight, which are added the vinyl chloride resin composition capable of fat is compatible with melt-kneading. In addition, (meth) acrylate here means acrylate or methacrylate.

請求項2に記載の発明(以下、「本発明2」と記す)による塩化ビニル系樹脂更生管は、上記本発明1の塩化ビニル系樹脂更生管において、熱可塑性エラストマーが、アクリロニトリル−ブタジエン共重合体、エチレン−酢酸ビニル共重合体及びエチレン−酢酸ビニル−一酸化炭素共重合体からなる群より選択される1種もしくは2種以上を含有する熱可塑性エラストマーであることを特徴とする。 The invention of claim 2 (hereinafter, "the present invention 2" and referred) vinyl chloride by resin rehabilitating pipe, in vinyl chloride resin rehabilitating pipe of the present invention 1, a thermoplastic elastomer, acrylonitrile - butadiene copolymerization A thermoplastic elastomer containing one or more members selected from the group consisting of a copolymer, an ethylene-vinyl acetate copolymer and an ethylene-vinyl acetate-carbon monoxide copolymer.

【0074】
【発明の効果】
以上述べたように、本発明の更生管は、上記記載の塩化ビニル系樹脂組成物からなるので、優れた機械的強度と耐衝撃性を高水準で兼備すると共に、施工性にも優れるものであり、既設管の更生(修復)用として好適に用いられる。
