Abstract

The invention discloses a diatom ooze coating material capable of effectively purifying indoor air, wherein the diatom ooze coating material consists of the following materials in parts by weight: 25-40 parts of inorganic film-forming material, 0.1-0.5 parts of inorganic pigment, 30-50 parts of diatomite, 10-40 parts of aggregate and 0.2-2 parts of powder additive. The diatom ooze coating material, which absorbs harmful substances indoor, particularly chemical substances such as formaldehyde, through the porous diatom ooze, and gradually degrades and absorbs harmful substances through the aggregate and powder additive, can improve degradation rate and removal rate of indoor harmful substances; the diatom ooze coating material can achieve a removal rate of more than 80% on indoor formaldehyde.

Description

technical field [0001] The invention relates to interior decoration materials, in particular to a diatom mud coating material for efficiently purifying indoor air pollution. Background technique [0002] In modern architectural design, the effective use of energy is increasingly considered, and the ventilation with the outside world is less and less. In this case, the indoor environment, especially the environment that has just been renovated, releases from various decoration materials. The concentration of pollutants is very high, and the pollutants cannot be discharged outdoors under the condition of insufficient ventilation. A large number of pollutants stay indoors for a long time, making the concentration of indoor pollutants very high. In severe cases, the concentration of indoor pollutants can exceed that of outdoors. Dozens of times as much. In order to effectively solve the problem of indoor environmental pollution, nano-titanium dioxide is added to traditional bui...
