Abstract

The invention provides a low-carbon high-efficiency compound magnesium silicate energy-saving and heat-insulating material, comprising the following raw materials in percentage by weight: 21-27 percent of sepiolite, 10-13 percent of silicate pulping cotton, 6-8 percent of perlite, 5-7 percent of diatomite, 1-3 percent of sodium silicate, 1-2 percent of magnesia, 14-23 percent of aluminum silicatehigh-temperature cotton, 14-22 percent of brucite, 6-8 percent of high-temperature binding agent, 1-3 percent of stabilizing agent and 3-4 percent of penetrating agent. Proved by the detection, the heat-insulating material has the advantages of lower heat conduction coefficient, wider use temperature, stronger bonding strength, high thermal shock resistant performance and no cracking, toxicity, dust and pollution and can be widely applied to chemical industry, petroleum, power, metallurgy, light industry, food, medicine, traffic, national defence, building and other industries.

Description

technical field [0001] The invention relates to an energy-saving heat preservation material, in particular to a low-carbon high-efficiency composite magnesium silicate energy-saving heat preservation material. Background technique [0002] In recent years, as the country's economic construction has entered a stage of rapid development, the domestic chemical industry, petroleum, electric power, metallurgy, light industry, food, medicine, transportation, national defense and other industries have an annual demand for thermal insulation materials of 1.5 billion cubic meters. Among them, the market demand for magnesium silicate insulation materials has reached 500 million cubic meters, with an average annual growth rate of more than 25%. In particular, the country's policy of forcing the use of high-quality thermal insulation materials in the construction industry has further expanded the domestic demand for magnesium silicate thermal insulation materials. In the face of high-s...
