Abstract

The invention belongs to the technical field of purification materials, and provides a normal-temperature purification material for removing formaldehyde and a preparation method of the normal-temperature purification material. The normal-temperature purification material for removing the formaldehyde is prepared from an inorganic component and an organic component, wherein the inorganic componentis prepared from the following components in parts by weight: 1-28 parts of attapulgite, 5-30 parts of montmorillonite, 0-15 parts of sepiolite and 0-13 parts of diatomite, and the organic componentis prepared from the following components in parts by weight: 0.1-3 parts of flavan-3-ols, 1.5-7 parts of chitosan, 2-8 parts of lysine, 1-5 parts of histidine, 0.5-8.2 parts of N-cocoyl glumatic acid, 1.5-5 parts of imidazolidinone and 0.5-3 parts of polyethylene glycol. According to the preparation method of the normal-temperature purification material, an organic matter aqueous solution is added into an inorganic mixture to be stirred and subjected to still standing for layering, and a mixture is obtained after the liquid level is higher than the upper surface of a solid by 0-1 mm in a drying oven, and the obtained mixture is cooled to the room temperature firstly, then precooled for 8-12 h at minus 20-minus 30 DEG C, and finally subjected to freeze drying at minus 50 DEG C. Through thetechnical scheme, the problem that in the prior art, a purification material is low in formaldehyde removal rate is solved.

Description

technical field [0001] The invention belongs to the technical field of purification materials, and relates to a normal-temperature purification material for removing formaldehyde and a preparation method thereof. Background technique [0002] Formaldehyde is a common indoor toxic pollutant gas. From automobiles to indoors, most spaces such as artificial boards, adhesives, and chemical fiber fabrics are used, and there are hidden dangers that the concentration of formaldehyde exceeds the standard or remains high. Formaldehyde has been identified as a carcinogen by the World Health Organization. Even a low dose of formaldehyde will have a strong stimulating effect on the eyes, skin and respiratory organs after long-term exposure to the human body. It has a strong carcinogenic and cancer-promoting effect and is easy to cause nasopharyngeal cancer , colon cancer, genetic mutations in the nucleus, and leukemia. Therefore, it is imperative to study formaldehyde removal. Effective...
