Abstract

The invention relates to a preparation method of a thermal insulation material. The preparation method comprises the following steps that 1, pulverized fuel ash is screened by a 200-mesh screen for usage after cement test grinding; 2, glass powder is screened by a 200-mesh screen for usage after cement test grinding; 3, 5-15 parts of pulverized fly ash, 85-95 parts of glass powder, 2-6 parts of sodium carbonate, 2-8 parts of titanium dioxide powder, 2-4 parts of borax and 30-35 parts of water are stirred evenly, and then slurry is obtained; 4, the slurry is put into a cement mortar test mold, then vibration and compaction are performed on a cement mortar jolt ramming table, then the cement mortar is put into an electrothermal blowing dry box, and drying is performed to form a blank; 5, the blank is put into a high-temperature resistance furnace, and sintering is performed to obtain the thermal insulation material.

Description

technical field [0001] The invention belongs to the field of inorganic material science and engineering, and in particular relates to a preparation method of a thermal insulation material. Background technique [0002] In recent years, fire accidents caused by building exterior wall insulation materials have occurred frequently, and the use of organic insulation materials has been greatly restricted. [0003] Fly ash is the fine ash collected from the flue gas after coal combustion. Fly ash is the main solid waste discharged from coal-fired power plants. The main oxides of fly ash in thermal power plants in my country are: silicon dioxide, aluminum oxide, ferrous oxide, ferric oxide, calcium oxide, titanium oxide, etc. With the development of the power industry, the discharge of fly ash from coal-fired power plants has increased year by year, becoming one of the largest industrial wastes in my country. If a large amount of fly ash is not treated, it will generate dust and ...
