Problems solved by technology

At present, the formaldehyde removers on the market can be basically divided into four categories: sealed formulations, which temporarily cover and seal formaldehyde, but are easily damaged and released again; oxidizing agents, which oxidize free formaldehyde molecules, but have no effect on polluting the interior and re-released pollutants. Function, large limitations when used; ammonia derivative type, nucleophilic addition reaction with formaldehyde, but excessive use will cause ammonia pollution, cause secondary pollution and not easy to remove; amino acid type, amino acid and formaldehyde react to form polymer compounds, However, there are problems such as insufficient response, incomplete removal, and low efficiency.

Abstract

The invention discloses an environment-friendly composite herbal extract formaldehyde removing agent. The environment-friendly composite herbal extract formaldehyde removing agent is formed by matching various natural herbaceous plants, is wide in source and low in cost, and contains a plurality of active groups; amidogens and formaldehyde perform a nucleophilic addition reaction, hydroxyls and the formaldehyde perform an electrophilic addition reaction, and aldehyde-containing substances and the formaldehyde perform an aldol condensation reaction, so that the effect of eliminating the formaldehyde is achieved by performing irreversible chemical reactions with the formaldehyde; the formaldehyde removing rate is up to 90 percent; the sterilizing rate reaches 85 percent; the environment-friendly composite herbal extract formaldehyde removing agent does not have toxicity to human bodies, cannot cause environmental pollution, has a quick response and good persistence, has the effects of eliminating the formaldehyde, purifying air, sterilizing and disinfecting and expelling mosquitoes, and can also relieve fatigue, restore consciousness and refresh; a production process is simple, and the preparation cost is low.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an environmental-friendly aldehyde-removing agent of compound herbal extracts. Background technique [0002] Many household items such as interior decoration materials, furniture, and textiles can release toxic gases such as free formaldehyde, benzene, and TVOC. Formaldehyde is one of the most serious indoor pollution sources and has been determined by the World Health Organization as a carcinogenic and teratogenic substance; formaldehyde has the longest volatilization period, and its hazards are manifested as strong irritation to the upper respiratory tract mucous membrane, eyes and skin, causing headaches , dizziness and other symptoms, severe respiratory irritation and edema will occur when the inhalation concentration is too high; formaldehyde is one of the important factors that produce diseases such as bad building syndrome and building-related syndrome.
