Lining method of metallic pipe
专利汇可以提供Lining method of metallic pipe专利检索，专利查询，专利分析的服务。并且PURPOSE:To improve adhesion to a metallic surface by a method wherein an adhesive layer composed of specific polyolefin is provided on the outer peripheral surface of a thermally expansible synthetic resin pipe through an intermediate layer of a specific composition and this layer is inserted into the metallic pipe and heated. CONSTITUTION:A composite to be prepared is composed of 100pts.wt. of unsaturated fatty group carbonic acid or polyolefin copolymerized by anhydride thereof, 5-100pts.wt. of 1 or more types of tackifier selected from terpene phenol resin or a resin group of 10 or more acid numbers and 30-200pts.wt. of polyolefin elastomer. An adhesive layer of polyolefin where unsaturated fatty carbonic acid or its anhydrate is copolymerized through an intermediate layer of said composition is provided on the external peripheral surface of a thermally expansible synthetic resin pipe. The synthetic resin pipe with said adhesive layer is inserted into a metallic pipe. Then, said resin pipe is enlarged in diameter by heating to line the inside of the metallic pipe.，下面是Lining method of metallic pipe专利的具体信息内容。
