Problems solved by technology

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 and use on a large scale in practice. The key problem is that its visible light utilization efficiency is very low. It can be excited by ultraviolet light with a wavelength less than or equal to 387.5nm, and the ultraviolet radiation in the sunlight reaching the ground is less than 5%, so the utilization rate of TiO2 for sunlight catalysis is very low, and it can be compounded by using other semiconductor materials and TiO2. Modification of TiO2 to develop photocatalysts with UV-Vis response

Embodiment 1

[0014] Produce dry powder type ecological interior wall paint according to the following steps:

[0015] (1) First prepare the TiO2-bismuth vanate-graphene ternary composite nanomaterial with ultraviolet-visible light photocatalytic function, the method is as follows:

[0016] At first prepare bismuth vanadate nano microsphere, its method is that 2mmol bismuth nitrate and 2mmol ammonium vanadate are dissolved in 30mL respectively, the nitric acid of 2mol / L and 30ml, in the sodium hydroxide aqueous solution of 2mol / L, then under room temperature, two The two solutions were mixed together to form a uniform suspension, and then 2.0 g of surfactant sodium dodecyl sulfonate was added to the mixed solution, and the stirring was continued at room temperature for 1 h, then transferred to a 100 ml reaction kettle, and kept at 180° C. The reaction was heated for 10 hours. After the reaction, the product was centrifuged and washed three times with distilled water and absolute ethanol; t...

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 ...
