The invention discloses a high temperature resistant material for an internal conveying tube of a thermal power conveying pipeline and a preparation method of the high temperature resistant material. The high temperature resistant material is prepared from the following components in parts by weight: 10-18 parts of polyurethane resin, 8-16 parts of epoxy resin, 2-6 parts of magnesium oxide, 2-5 parts of lead oxide, 3-8 parts of aluminum hydroxide, 2-5 parts of an anti-aging agent 4010NA, 1-4 parts of a curing agent, 1-4 parts of an antioxidant, 2-6 parts of rare earth oxides and 2-6 parts of titanium carbide. The preparation method comprises the following steps: mixing the magnesium oxide, the lead oxide, the aluminum hydroxide, the rare earth oxides and the titanium carbide, and calcining in a high temperature furnace; grinding in a ball mill; mixing the polyurethane resin, the epoxy resin, the anti-aging agent 4010NA, the curing agent and the antioxidant, adding powder materials, and stirring so as to obtain a granular material; performing sizing, traction and cooling molding on the granular material by using a molding machine. The high temperature resistant material has the advantages of being excellent in high temperature resistance property, long in service life and the like.

Description

technical field [0001] The invention relates to the field of material preparation for heat transmission pipelines, in particular to a high-temperature-resistant material for inner transmission pipes of heat transmission pipelines and a preparation method thereof. Background technique [0002] Thermal transmission pipelines are often used in daily life and industrial production, especially in the field of central heating, central cooling and other medium transmission areas. Thermal pipelines are often used to transport steam or hot water. Among them, thermal pipelines generally include inner transmission pipes, outer casings As well as the heat insulating layer between the outer shell and the inner delivery pipe, the outer shell is mainly made of metal, and the heat insulating layer can be foam heat insulating material, polyurethane foam. [0003] Among them, the inner conveying pipe of the thermal conveying pipeline generally has the defects of poor heat resistance, poor mec...
