A kind of benzene series trapping agent and preparation method thereof

Abstract

The invention belongs to the technical field of chemical preparations, and in particular relates to a benzene series trapping agent and a preparation method thereof; the benzene series trapping agent comprises the following raw materials in parts by weight: 5-8 parts of polyacrylamide, 10-20 parts of starch, sorbic acid 8~15 parts, 10~15 parts of sodium sorbate, 30~45 parts of plant flower extract, 5~10 parts of penetrant, 15~20 parts of sepiolite powder, 1~3 parts of manganese cerium composite oxide catalyst, crosslinking Rectorite 5~10 parts, chitosan 10~20 parts, deionized water 80~100 parts. The benzene series capture agent of the present invention has good adsorption to benzene series, and has a long service life, thereby solving the pollution of benzene series after interior decoration, and can also treat certain diseases such as colds, intestinal tracts, and skin. Germs and viruses are effectively inhibited or killed, which is beneficial to people's health.

Description

technical field [0001] The invention relates to the technical field of chemical preparations, in particular to a benzene series trapping agent and a preparation method thereof. Background technique [0002] Benzene series (BTEX) is a class of volatile organic compounds (VOC), mainly including benzene, toluene, ethylbenzene, o-, m-, p-xylene, cumene, styrene and other compounds. The benzene series in indoor air mainly come from paint, glue and interior wall paint. Various adhesive solvents used in decoration contain a large amount of such substances. The content of benzene or toluene in banana water as paint thinner is as high as 50-55%. The polluted air outside will also affect the indoor air with its pollution degree, endangering people's health. Benzene series are toxic and carcinogenic, and pose a great threat to human health. Benzene is irritating to the skin, eyes and upper respiratory tract. Frequent exposure to benzene can cause the skin to become dry and desquamat...

AI Technical Summary

Problems solved by technology

[0003] Since the benzene series all contain stable benzene ring structures, and the concentration of benzene series in the indoor air is often low, and the removal of the benzene series in the indoor air must be carried out at room temperature, so the commonly used heat treatment in industry Gas purification methods such as incineration and biodegradation are difficult to effectively remove low-concentration benzene series

In the prior art, activated carbon is used as the adsorbent, and the service life of activated carbon is short, and its adsorption function is very limited. After a period of time, the adsorption function will be lost due to the absorption, so that the filter element or filter material needs to be replaced continuously. ; It not only consumes a lot of raw materials, but also increases the burden on users; and making activated carbon is an industry with high energy consumption and high pollution

The neutralization method is used to eliminate, the removal rate is low, and it is easy to rebound with the change of temperature after neutralization, so that the content of benzene series in the air will rise again, and it cannot be completely removed
