Description
Technical Field
The invention belongs to the technical field of attapulgite adsorbent preparation, and particularly relates to an attapulgite adsorbent for indoor air purification and a production process thereof.
Background
With the rapid development of economy, the living standard of people is gradually improved, people have higher requirements on the quality of the home environment, and home decoration becomes fashionable. However, people often neglect the influence of the decorated living room environment on health and safety. It is well known that indoor environmental pollution seriously affects human health. Various indoor articles can release various harmful substances, and especially in newly decorated rooms, the emission of harmful gases such as benzene, formaldehyde and the like is extremely striking.
Attapulgite, which is called attapulgite for short, is a water-containing magnesium-aluminum-rich silicate mineral with a layer chain structure, and belongs to a natural nano material. The attapulgite has huge specific surface area, and has strong ion exchange capacity, adsorption capacity and decolorizing capacity. Research shows that the nano clay has excellent adsorption effect on various metal ions, dyes, partial organic matters and microorganisms, and has the advantages of low cost, simple regeneration and wide application prospect in indoor air purification.
Disclosure of Invention
In order to meet the requirements, the invention provides the attapulgite adsorbent for indoor air purification and the production process thereof, and the attapulgite adsorbent for indoor air purification and the production process thereof provide the attapulgite adsorbent with excellent adsorption capacity, and the product is non-toxic and harmless, has no harmful substances in the production process, and is safe and environment-friendly.
The technical scheme adopted by the invention for solving the technical problems is as follows: a attapulgite adsorbent for indoor air purification: the raw materials by mass are: 50-80 parts of attapulgite, 20-30 parts of medical stone, 20-30 parts of activated carbon, 10-20 parts of glutinous rice flour, 3-5 parts of xanthan gum, 3-5 parts of gel and 1-2 parts of lignocellulose;
the method comprises the following steps:
(1) mixing attapulgite, medical stone and active carbon, grinding to 130 meshes at 100 meshes, treating at 300 ℃ for 3-5h at 200 meshes, cooling, adding glutinous rice flour, and mixing uniformly to obtain mixed powder;
(2) adding xanthan gum and gel into the mixed powder obtained in the step (1) to obtain a mixed solution;
(3) mixing the mixed solution in the step (2) with lignocellulose, stirring at 60-70 ℃ for 20-30min at 600r/min, freeze-drying at-10 ℃ to-50 ℃ for 8-12h, and finally standing at room temperature for 2-4h to obtain a mixed matrix;
(4) and (4) freeze-drying the mixed matrix obtained in the step (3), crushing the obtained material to be 100-mesh and 130-mesh, and subpackaging the reproduced particles to obtain a finished product.
The active carbon is prepared by pyrolyzing and activating carbon-containing raw materials such as wood, coal, petroleum coke and the like, and has a developed pore structure, a larger specific surface area, abundant surface chemical groups and a carbon material with stronger specific adsorption capacity. The medical stone is a compound mineral or medicinal rock which is nontoxic and harmless to organisms and has certain bioactivity, and can increase the components of adsorbed harmful substances and provide a health-care effect. Lignocellulose increases the strength of the granulation, and all ingredients are non-toxic and harmless.
The invention has the beneficial effects that: the product is non-toxic and harmless, and no harmful substances are generated in the production process, so that the product is safe and environment-friendly.
