Abstract

The invention discloses a diatom mud negative ion dry powder coating material, and belongs to the technical field of coating materials. The diatom mud negative ion dry powder coating material comprises the following components by mass: 22.8-28.9% of ash-calcium powder, 12.2-14.2% of diatom mud, 5.5-7.2% of a negative ion additive, 3.1-4.8% of an antibacterial agent, 0.8-1.5% of anatase type titanium dioxide, 0.76-0.92% of talc powder, 0.76-0.92% of aluminum silicate, 0.37-0.52% of kaolin, 0.37-0.52% of wollastonite, 0.18-0.32% of a surfactant, 0.76-0.92% of redispersible latex powder, 0.0030-0.0055% of modified seaweed glue powder, and the balance of heavy calcium powder. The diatom mud negative ion dry powder coating material of the present invention has characteristics of efficient absorption of formaldehyde and other harmful gases, natural and long-lasting release of negative ions, strong anti-mildew and bactericidal ability, good gas permeation, indoor air humidity adjusting, good coating strength, good coating toughness, good washing resistance, and the like.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a diatom ooze anion dry powder coating and a preparation method thereof. Background technique [0002] The quality of indoor air has an important impact on the health of the human body. With the development and progress of society, more and more buildings are decorated indoors. Generally, new furniture is added indoors or paint is painted on the walls. Decorate the interior, but after decoration, the furniture or paint in the room is easy to volatilize harmful gases such as formaldehyde and VOC, and the painted wall is prone to mold or bacteria, which will affect human health. In addition, in the living environment, there are phenomena such as industrial waste discharge, garbage burning, and electromagnetic pollution, which lead to a sharp decrease in negative ions in outdoor air and indoor air, which will reduce the body's immunity and affect human health. With the continuous ...
