Abstract

The invention discloses a powder curing agent for expanded perlite thermal insulation plates, and a preparation method thereof, wherein the powder curing agent comprises the following raw materials byweight: 50-60 parts of power generation chimney ash, 3-8 parts of industrial aluminum sulfate, 5-10 parts of active silica, 25-35 parts of cement clinker powder, 8-12 parts of fluorite powder, and 0.5-1 part of a retarder. According to the present invention, the powder curing agent is prepared from the power generation chimney ash, the industrial aluminum sulfate, the active silica, the cement clinker powder, the fluorite powder and the retarder so as to achieve the reutilization of the industrial and mining waste materials; and the prepared powder curing agent has the rapid setting propertyof gypsum and the high strength of cement, has low-alkalinity so as to significantly reduce the alkali accumulation and peeling phenomena of the thermal insulation plate, further can eliminate radioactive materials, and can flexibly control the molding time during the molding.

Description

technical field [0001] The invention relates to building materials, in particular to a powder solidifying agent for expanded perlite insulation boards and a preparation method thereof. Background technique [0002] Building energy conservation is an industry supported by the national industrial policy. At present, building energy-saving materials are mainly divided into inorganic thermal insulation lightweight aggregates and organic thermal insulation lightweight aggregates. However, due to the characteristics of the chemical properties of materials, neither inorganic systems nor organic systems can simultaneously meet the requirements of thermal insulation and energy saving performance and fire safety. In terms of thermal insulation performance, organic materials are superior to inorganic materials; in terms of fire safety performance, inorganic thermal insulation materials are slightly better. In recent years, expanded perlite among inorganic thermal insulation materials ...
