Problems solved by technology

[0003] At present, the natural purification products on the market are mainly activated carbon and bamboo charcoal, but these two types of products only have a simple physical adsorption function, and cannot remove harmful substances such as formaldehyde and benzene. Adsorbed to saturation, and may even be re-released under certain conditions
Although photocatalyst activated carbon has also appeared on the market, the preparation process is complicated and it is easy to be saturated during use.

Abstract

The invention discloses anion-containing diatom nano mineral crystal particles and a preparation method thereof. The nano mineral crystal particles are prepared from raw materials in parts by weight as follows: 50-70 parts of sepiolite, 0.1-0.5 parts of anion powder, 5-10 parts of attapulgite, 10-20 parts of activated carbon, 5-10 parts of diatomite, 10-15 parts of kaolin and 3-5 parts of manganese oxide. The sieved sepiolite, anion powder, attapulgite, activated carbon, diatomite, kaolin and manganese oxide are weighed and mixed, and a proper quantity of sodium carbonate aqueous solution is added, and spheres are obtained through granulation; the nano mineral crystal particles are prepared after primary drying and activation. The prepared nano mineral crystal purification particles can adsorb formaldehyde, benzene, TVOC and other harmful gases and can play roles in decomposing, removing and releasing anions. Mineral materials such as sepiolite and attapulgite are used for bonding, the pure nature of the product is guaranteed, the preparation steps are simple, and the process is mature and suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of environmental protection materials, in particular to a diatom nano-mineral particle containing negative ions and a preparation method thereof. Background technique [0002] With the rapid improvement of people's living standards in our country, modern people's pursuit of quality of life and health is getting higher and higher. As a result, the housing area increases and the decoration becomes more and more luxurious and tight. However, due to our country's sanitary quality standards for building decoration materials, product quality supervision and management are not in place, resulting in a large number of inferior decoration materials flooding the building materials market. The survey shows that among the indoor environmental pollutants, four categories such as formaldehyde, ammonia, benzene (series) and radioactive substances are ubiquitous, the most harmful, and have become the greatest source of harm...
