Abstract

The invention relates to a high-strength magnesium steel heat-insulating material, a preparation method thereof and a heat-insulating block made of the high-strength magnesium steel heat-insulating material, belonging to the technical field of chemical industry. The high-strength magnesium steel heat-insulating material is mainly used for support and heat insulation of pipelines and equipment. The high-strength magnesium steel heat-insulating material is prepared from the following components in parts by weight: 4000-4500 parts of magnesium oxide, 2500-3000 parts of magnesium chloride, 5-10 parts of ferrous sulfate, 5-10 parts of trisodium phosphate, 5-10 parts of oxalic acid and 2800-3300 parts of glass fiber. The invention has favorable functions of supporting and protecting pipelines and equipment, and has the characteristics of low coefficient of heat conductivity, favorable thermal-insulation effect, aging resistance, water resistance, corrosion resistance, heat resistance, fire resistance, no toxicity and no smell.

Description

technical field [0001] The invention relates to a high-strength magnesium-steel heat-insulating material and a manufacturing method thereof, and a heat-insulating block made thereof, which is mainly used for supporting heat-insulating pipes and equipment, and belongs to the technical field of chemical industry. Background technique [0002] Heat energy is widely used in my country's industrial production and people's lives, and in the process of heat energy transmission, it must pass through related valves, pipes, bends and other equipment to form a heat energy transmission network. In the long-distance heat transmission process, the transmission pipe network must have a certain support frame, so that the heat energy transmission pipe network is overhead from the ground. If the heat energy transmission pipe network passes through the road, the support frame needs to be higher. In the prior art, the supporting frame is installed in direct contact with the heat transfer pipe n...
