Abstract

The invention discloses a negative oxygen ion dry powder paint, belonging to the technical field of paints. The paint comprises the following components in percentage by mass: 25-35% of ash calcium powder, 6.2-8.0% of diatomite, 4.5-6.5% of negative ion additive, 1.5-5.0% of antimicrobial agent, 0.15-0.80% of talcum powder, 0.15-0.80% of kaolin, 0.15-0.50% of wollastonite, 0.05-0.15% of surfactant, 0.55-1.5% of redispersible latex powder, 1.2-1.8% of light calcium carbonate powder, 0.15-0.50% of lithopone and the balance of heavy calcium carbonate powder. The paint is capable of efficiently absorbing formaldehyde and other harmful gases and naturally and enduringly releasing negative ions, has the characteristics of high mildew resistance, high bactericidal capacity and favorable air permeability, and can adjust the humidity of indoor air. The coating has the characteristics of favorable strength, favorable toughness, favorable scrubbing resistance and the like.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a negative oxygen ion dry powder coating and a preparation method thereof. Background technique [0002] The quality of indoor air has an important impact on human health. With the development and progress of society, more and more buildings are decorated indoors, usually by adding new furniture or painting walls to 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. Moreover, 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 immunity of the human body and affect human health. In addition, the humidity of indoor air also has ...
