Abstract

The invention relates to the technical field of building materials, specifically to a building plastic tile used for assisting in eliminating haze and a preparation method thereof. According to the invention, during formation of silicon dioxide, through disturbance of a pore-forming agent, zinc oxide nanosheets are connected into a compound with a microporous structure; the zinc oxide nanosheet microporous compound is loaded with a foaming agent; the compound is used for manufacturing a plastic tile; gas foaming is easy to be generated; the zinc oxide nanosheet microporous compound can maintain good micropores; meanwhile, an air channel is formed in plastic, so air is easy to be adsorbed, and harmful substances in the air are degraded.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a building plastic tile used to assist in eliminating smog and a preparation method thereof. Background technique [0002] Haze weather seriously affects people's quality of life, and nitrogen oxides and sulfur oxides are one of the main causes of haze weather. Smog is produced by the combination of dust in the air and organic matter, and the formed particles with a diameter less than or equal to 2.5 microns enter the lungs through the respiratory tract and cause serious harm to the human body. [0003] At present, the elimination of nitrogen oxides and sulfur oxides is relatively mature, mainly through desulfurization and denitrification treatment of vehicle exhaust and palace factory emissions. Such as the use of ammonia catalytic reduction of nitrogen oxides; the use of lime water adsorption treatment of sulfur dioxide and so on. However, there is no unified treat...
