The invention discloses a heatproof and heat-conductive reinforced ultrahigh-molecular weight polyethylene tube and a production method thereof. The tube belongs to a composition of a polymeric compound, and comprises, by weight, 60-95 parts of ultrahigh-molecular weight polyethylene having a viscosity average molecular weight of 2.5-6.5 millions, 5-40 parts of copper-plated sheet silicate, 0.05-2parts of a coupling agent, 0.06-0.5 part of an antioxidant and 0.1-5 parts of a lubricant. The production method comprises the following steps: performing high-speed mixing on all the raw materials,adding the obtained mixture into a continuous internal mixing extruder, performing extrusion molding, sizing the obtained extruded composite material, cooling the sized composite material to normal temperature, and cutting the cooled composite material to obtain the heatproof and heat-conductive copper-plated sheet silicate reinforced ultrahigh molecular weight polyethylene tube. The heatproof property and the heat conductivity of the tube are well improved; and the copper-plated sheet inorganic filler is adopted, so the production cost is reduced.
