Abstract

The invention relates to the field of anti-haze building materials, and discloses an anti-haze gypsum wall material for a prefabricated building and a preparation method of the anti-haze gypsum wall material. The preparation method comprises the following preparation processes that (1) a photocatalyst, a foaming agent, a binding agent and porous glass microspheres are added into deionized water toprepare a porous glass microsphere glue solution; (2) a micropore wall substrate material is prepared from raw materials of beta-semi-hydrated phosphogypsum, cement, fly ash, a foaming agent, a polycarboxylic acid water reducer, a salt waterproof agent, waste plastic fiber, water, a crystal modifier, polyvinyl alcohol and hydrogen-containing silicone oil; and (3) the glue solution is sprayed on the surface of the substrate material, and thus the gypsum wall material with the haze removing function is obtained. The gypsum wall material prepared through the method is high in porosity, high in adsorption ability and high in catalytic efficiency for nitrogen oxide, the preparation process is simple, direct fabricating can be achieved, the construction difficulty is small, raw materials are easy to obtain, the cost is low, and the gypsum wall material can be directly applied and promoted on a large scale.

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...
