Abstract

The invention relates to the field of anti-smog building materials, and discloses an anti-smog gypsum wall material for prefabricated buildings and a preparation method thereof. It includes the following preparation process: (1) adding photocatalyst, foaming agent, binder, and porous glass microspheres into deionized water to make porous glass microsphere glue; (2) using β-hemihydrate phosphogypsum, cement, Fly ash, foaming agent, polycarboxylate water reducing agent, salt water repellent, waste plastic fiber, water, crystal transformation agent, polyvinyl alcohol and hydrogen-containing silicone oil are used as raw materials to make microporous wall matrix materials; ( 3) Spray the glue on the surface of the base material to obtain a gypsum wall material with the function of removing haze. The gypsum wall material prepared by the invention has high porosity, strong adsorption capacity, high catalytic efficiency for nitrogen oxides, relatively simple preparation process, direct assembly, low construction difficulty, easy to obtain raw materials, low cost, and can be directly Large-scale promotion and application.

Description

technical field [0001] The invention relates to the field of anti-smog building materials, and discloses an anti-smog gypsum wall material for prefabricated buildings and a preparation method thereof. Background technique [0002] Haze weather is a state of air pollution. It is a general expression of the excessive content of various suspended particulate matter in the atmosphere. Haze weather is usually formed by the mixed action of various pollution sources. Its sources are various, mainly due to the extensive industrial structure of the development mode The main sources are soil dust, coal combustion, vehicle exhaust emissions, marine aerosols and steel industry production pollution. In recent years, haze pollution and indoor air quality problems have become increasingly serious. Volatile organic pollutants (VOCs) and PM2.5, as the main pollution sources of haze and indoor air pollution, have received widespread attention. [0003] With the continuous growth of my countr...
