A kind of domestic attapulgite adsorbent and preparation method thereof

Abstract

The invention discloses a household attapulgite adsorbent, which comprises adsorbent particles, wherein the adsorbent particles are integrally semispherical, each adsorbent particle consists of an adsorbent particle upper part, a bitterness agent layer and an adsorbent particle lower part, the bitterness agent layer is sandwiched between the adsorbent particle upper part and the adsorbent particlelower part, the surface of the adsorbent particle upper part is provided with a plurality of thorn-shaped projections, the adsorbent particle lower part is provided with a pit, the surface of the pitis also provided with a plurality of thorn-shaped projections, and the bitterness agent layer is composed of bitterness agent powder. According to the invention, ingenious design is carried out on the product structure and the raw materials to obtain the attapulgite adsorbent with mistaken eating prevention function and excellent adsorption capacity.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to a household attapulgite adsorbent and a preparation method thereof. Background technique [0002] With the rapid development of social economy, the living standard of the people is getting better and better, the pursuit of quality of life is getting higher and higher, and higher and higher requirements are put forward for the indoor air environment. The fresh air system and air purifier are mostly used to purify indoor air. The fresh air system is expensive, and the installation is cumbersome, and the maintenance cost in the later period is not low; the quality of the air purifier varies, and the price and filter replacement cost are not low. . Air purification adsorbent has the characteristics of low price and convenient use. [0003] Attapulgite is the abbreviation of attapulgite clay. It is a non-metallic mineral resource. It is a layer chain structure of water-containing m...

Problems solved by technology

[0004] The existing household attapulgite adsorbents are mainly divided into powder type and spherical particle type. The powder type is generally packaged in a breathable bag, which has a small contact area with the air and a slow adsorption rate. If the packaging bag is damaged, the powder leaks out and is difficult to clean; the granular type Generally, it is taken out of the package and then placed in a container. The particles are in close contact with each other. The surface layer is mainly in contact with the air. Turned over, the spherical particles are rolling around and it is not easy to clean up, so it is of great significance to design an adsorbent that has the function of preventing accidental ingestion and has excellent adsorption capacity
