A dry powder type ecological interior wall coating based on shell powder

Abstract

Dry powder type ecological interior wall paint based on shell powder is disclosed. Raw materials of the paint include, by mass, 30-50% of the shell powder the particle size of which is 500-1300 meshes, 10-20% of kaolin, 10-20% of precipitated calcium carbonate, 10-20% of nanometer silica, 1-10% of a TiO2-bismuth vanadate-graphene ternary nanometer composite material and 10-20% of adhesive powder. The paint has high ultraviolet-visible light photocatalysis functions, functions of adsorbing and decomposing harmless gas and odor, and antibacterial, sterilizing and antistatic functions, has characteristics of excellent physical performance, elegant appearance, and the like, can be widely applied in indoor decoration and overcomes disadvantages that indoor air purification materials at present are high in cost, high in energy consumption, low in visible light utilization rate, and the like.

Description

technical field

[0001] The invention relates to an ecological interior wall paint, in particular to a dry powder type ecological interior wall paint based on shell powder. Background technique

[0002] In the interior decoration process, a large number of paints, composite panels, leather, foam fillers, plastic veneers and other decoration materials contain a large amount of volatile toxic compounds (VOC). These toxic and harmful gases seriously endanger human health and the living environment. . At home and abroad, more and more attention has been paid to the research and application of ecological and environmental protection materials with air purification and antibacterial functions. Ti02 photocatalysis technology is considered to be a green environmental protection technology with great research and application prospects for deep purification of volatile organic pollutants. , but there are many problems in TiO2 photocatalytic materials that make it difficult to produce ...
