Fly ash environment-friendly composite wallboard and production method thereof

Abstract

The invention discloses a fly ash environment-friendly composite wallboard and a production method thereof. The main raw materials include fly ash, haze powder, attapulgite clay tailings powder, plant fiber powder, nano hollow microspheres, an antifoaming agent, expanded perlite and a lipid waterproof agent; and the main process flow of the production method comprises: material selection, grinding, mixing and stirring, secondary mixing, mould reversing, firing and facing to obtain a finished product. In the invention, the fly ash, haze powder, attapulgite clay tailings powder and plant fiber powder are all waste gas materials, and the edge materials are effectively recycled while environmental pollution is reduced. The production method disclosed by the invention has the following advantages that: the production technology is simple, the adopted materials are environment-friendly, the resources are saved, and the fly ash fired into a board can be processed and recycled; and meanwhile, the recycled haze is effectively utilized, the utilization of waste materials is enhanced, and the obtained board has good waterproof and thermal insulation effects.

Description

Technical field: [0001] The invention relates to the field of building materials, in particular to a fly ash environment-friendly composite wallboard and a production method thereof. Background technique: [0002] The smog is mainly composed of sulfur dioxide, nitrogen oxides and inhalable particulate matter. They combine with the fog to make the sky instantly dark and gloomy, seriously polluting our living environment. The English abbreviation of particulate matter is PM, which is monitored in Beijing The most important thing is fine particulate matter (PM2.5), that is, pollutant particles with an aerodynamic equivalent diameter less than or equal to 2.5 microns. This particle itself is not only a pollutant, but also a carrier of toxic substances such as heavy metals and polycyclic aromatic hydrocarbons. At present, some scientific research teams or individuals have developed devices for collecting smog, and some people have even made smog into bricks or rings. Utilize,...
