Interior wall coating using shell powder as main component

Abstract

The invention discloses an interior wall coating using shell powder as a main component, which is prepared by using shell calcium carbonate and shell calcium oxide as main materials, using redispersible latex powder as an adhesive, adding nano titanium dioxide, anion powder and cellulose ether as functional addition materials, mixing and stirring. Because no harmful substance is added in the interior wall coating, the interior wall coating not only can not emit harmful gases, such as formaldehyde, benzene, ammonia gas, TVOC and the like, but also has the functions of adsorbing and decomposing the harmful gases and has a certain breath humidifying function; and meanwhile, the interior wall coating has the characteristics of simple transportation and construction, and spraying construction can be carried out by only adding pigment and water and uniformly mixing.
