Abstract

The invention relates to the field of air purification materials, and discloses diatom ooze capable of efficiently purifying air and a preparation method thereof. The preparation method comprises thefollowing preparation processes: (1) adding ultrafine tourmaline powder and a cerium salt solution into a mixed solution of absolute ethyl alcohol and water to prepare a uniform suspension; (2) uniformly mixing a titanium source with absolute ethyl alcohol, and dropwise adding the mixture into the suspension to prepare a standing solution; (3) drying the standing liquid, adding acetone, and calcining to obtain a cerium dioxide doped titanium dioxide / tourmaline composite material; and (4) uniformly mixing the composite material with diatomite, hydrotalcite, titanium dioxide, a cementing material, redispersible latex powder, polypropylene staple fibers, a mildew preventive, a thixotropic agent and water to obtain the diatom ooze capable of efficiently purifying air. According to the diatom ooze prepared by the invention, cerium dioxide is doped with titanium dioxide and tourmaline, so that the photocatalysis capability of titanium dioxide and the negative ion release capability of tourmaline can be effectively improved, and the air purification efficiency of the diatom ooze is greatly improved.

Description

technical field [0001] The invention relates to the field of air purification materials, and discloses a highly efficient air purification diatom ooze and a preparation method thereof. Background technique [0002] With the continuous advancement of industrialization and urbanization, problems such as air pollution and water pollution have become increasingly prominent. In recent years, the frequent "visits" of haze weather have seriously affected people's daily life, and PM2.5 has become a daily monitoring At the same time, due to the use of interior decoration materials, daily chemicals, and toxic substances released from furniture and building materials, the indoor air quality has plummeted, such as formaldehyde and other harmful gases, benzene radon, etc. Carcinogens cause various diseases in the human body living in it for a long time. Therefore, air purification has become a worldwide important issue. [0003] At present, the main air purification technologies includ...
