Silicic acid mud interior wall decorating material and preparation method thereof

Abstract

The invention relates to a silicic acid mud interior wall decorating material and a preparation method thereof. The silicic acid mud interior wall decorating material mainly comprises diatomite, sepiolite, kaolin, sierozem, coarse whiting, wollastonite, white cement, silica sand, talcum powder, nanometer titanium dioxide, ethylene-vinyl acetate copolymer, cellulose ether, aluminium-magnesium silicate, easily dispersed fiber, inorganic pigments and has the functions of humidity control and air purification. The preparation method comprises the following steps of: firstly acidizing the diatomite, the sepiolite and the kaolin, removing harmful ingredients in the diatomite, the sepiolite and the kaolin, improving the activation property of the material, then filtering, washing, drying and crushing, and finally adding the diatomite, the sepiolite and the kaolin and the other components to a dry powder blender for uniformly stirring. When being used, water is added to powder, so that the powder is prepared into paste or emulsion; the silicic acid mud interior wall decorating material is suitable for roll coating, spray finishing, blade coating and the like in interior wall decoration and has the functions of indoor humidity adjustment, peculiar smell elimination, removal of harmful gases such as formaldehyde and toluene in air and lasting environmental protection and simultaneously has the characteristics of rich color, strong sense of texture and environmental friendliness.

Description

technical field [0001] The invention belongs to interior decoration materials, in particular to a kind of diatomite, sepiolite, kaolin, lime calcium, heavy calcium, wollastonite, white cement, silica sand, talcum powder, nano-titanium dioxide, ethylene-vinyl acetate copolymer, The main raw materials are cellulose ether, magnesium aluminum silicate, easily dispersible fiber and inorganic pigment, and the silicate mud interior wall decoration material with the functions of humidity control and air purification and its preparation method are mainly suitable for interior wall decoration. Background technique [0002] At present, the indoor air pollution caused by conventional decorative materials widely used in the market has attracted more and more attention. With the continuous improvement of people's living conditions, people's selection standards for wall decoration materials are getting higher and higher, and The environmental protection performance of the material is liste...
