    • The present invention relates to a joining material for a polyethylene pipe, to a method for joining a polyethylene pipe using the joining material, and to a joining material for a polyethylene pipe, a connection pipe and a heating sheet, used in said method. More particularly, the present invention relates to a joining material for a polyethylene pipe to be used in joining a polyethylene pipe, wherein the inside of the joining material is packed with joining particles including carbon nanotubes and polyethylene. The polyethylene pipe to be joined is fitted to a connection pipe, and the joining material filled with joining particles is inserted between the polyethylene pipe and the connection pipe, and a heating sheet wraps around and melts the joining member, and thus, the polyethylene pipe is connected. The joining material for a polyethylene pipe according to the present invention contains carbon nanotubes, which have superior thermal conductivity, in a heat transfer layer formed on the outer surface of the joining material and the joining particles, and therefore the joining material of the present invention may quickly transfer heat from a heat source to the polyethylene. As a result, polyethylene may be quickly melted to enable the polyethylene pipe to be connected in a short time period.
    • 本发明涉及聚乙烯管的接合材料,使用该接合材料的聚乙烯管的接合方法以及用于所述方法的聚乙烯管,连接管和加热片的接合材料。 更具体地说,本发明涉及用于接合聚乙烯管的聚乙烯管的接合材料,其中接合材料的内部填充有包括碳纳米管和聚乙烯的接合颗粒。 将要接合的聚乙烯管装配到连接管上,并且将填充有接合颗粒的接合材料插入聚乙烯管和连接管之间,并且加热片卷绕并熔化接合部件,因此聚乙烯管 已连接。 根据本发明的聚乙烯管的接合材料在形成在接合材料的外表面上的传热层和接合颗粒中包含具有优良导热性的碳纳米管,因此本发明的接合材料 可以将热量从热源快速传递到聚乙烯。 结果,聚乙烯可以快速熔化,以使聚乙烯管在短时间内连接。
