JOINING MATERIAL FOR POLYETHYLENE PIPE, AND JOINING METHOD USING SAME

摘要

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.
