Abstract

The invention provides a graphene reinforced heat-resistant polyethylene composite pipe and a preparation method thereof and belongs to the technical field of pipeline materials. The invention mainly aims to solve the technical problem that a general polyethylene pipe is not high-temperature-resistant and is easy to damage. The graphene reinforced heat-resistant polyethylene composite pipe provided by the invention comprises the following components in parts by weight: 80-90 parts of hexane copolymerizing high-density heat-resistant polyethylene, 0.1-3 parts of graphene, 2-4 parts of fluorine-containing styrene, 2-4 parts of a coupling agent, 6-8 parts of a plasticizer, 1-3 parts of an antioxidant, 2-4 parts of a lubricating agent, 10-30 parts of a dissolution agent and 0.1-0.3 part of a surfactant. The invention further provides a preparation method of the graphene reinforced heat-resistant polyethylene composite pipe. The method comprises the following steps: dissolving, stirring, performing ultrasonic treatment, mixing, heating, performing single-screw extrusion and the like. The various raw materials are high in compatibility, the characteristics of the raw materials are effectively achieved, and the prepared pipe has high strength and heat resistance.

Description

technical field [0001] The invention relates to the technical field of pipeline materials, in particular to a graphene-reinforced heat-resistant polyethylene composite pipe and a preparation method thereof. Background technique [0002] Plastic pipes are high-tech composite chemical building materials, and chemical building materials are the fourth largest category of new building materials emerging in the contemporary era after steel, wood, and cement. In recent years, chemical building materials have made great progress and developed rapidly in our country, especially the widespread use of new environmentally friendly plastic pipes, which has set off a revolution to replace traditional building materials. Due to the advantages of small water loss, energy saving, material saving, ecological protection, and convenient completion, plastic pipes are currently widely used in the fields of building water supply and drainage, urban water supply and drainage, and gas pipes, and ha...
