Plant essential oil formaldehyde-removing agent and application thereof

Abstract

The invention relates to a plant essential oil formaldehyde-removing agent and application thereof; the formaldehyde-removing agent is made by mutually compounding Saposhnikovia divaricate essential oil with one of Astragalus membranaceous essential oil, Houttuynia cordata essential oil, Artemisia vulgaris essential oil, Forsythia suspense essential oil, cinnamon essential oil, clove essential oil, mint essential oil, honeysuckle essential oil and tangerine peel essential oil; all the essential oils are extracted from natural plants, and the formaldehyde-removing agent is effective in clearing formaldehyde, free of stimulus to human bodies, suitable for long-term use, free of secondary pollution and significant in both economic benefit and environmental significance.

Description

technical field [0001] The invention belongs to the technical field of air purifiers, and in particular relates to a plant essential oil formaldehyde remover and its application. Background technique [0002] Formaldehyde, also known as formaldehyde, is a colorless gas with a strong pungent odor under standard conditions. It is easily soluble in water, ether and alcohol. It is listed as one of the top ten chemical raw materials and is widely used in chemical synthesis, food Processing, building materials processing, fur processing and other fields. However, formaldehyde has high toxicity, is a carcinogenic and teratogenic substance, has a very strong reducing property, and is very easy to combine with various substances. The main hazard of formaldehyde can be manifested as irritation to the skin and mucous membranes. After inhaling more high-concentration formaldehyde accidentally, severe irritation and edema will occur in the respiratory tract, and symptoms such as eye sti...

Problems solved by technology

[0003] At present, the methods for removing formaldehyde mainly include ventilation, chemical reaction, adsorption, and biochemical methods. Among them, ventilation is the most commonly used method. Strengthening ventilation can introduce fresh outdoor air into the room. , to reduce the concentration of indoor air pollutants. This method is simple and economical, but it has the disadvantage of not being able to completely remove indoor pollutants; the chemical reaction method is to spray chemical reagents in the air or in furniture to make them chemically react with formaldehyde, and then To achieve the purpose of removing formaldehyde, the purifiers used in the chemical method are mostly chemically synthesized. Although they are non-toxic, they are not beneficial to human inhalation, and generally play a role in masking the smell, and cannot fundamentally remove formaldehyde; The carbon is continuously adsorbed for a long time to reduce the formaldehyde content, but the activated carbon is saturated. When the external environment such as temperature and wind speed changes, the adsorbed pollutants may be released to form secondary pollution; the biochemical method mainly uses microbial enzymes to decompose Harmful components of organic matter, according to the characteristics of biochemical reactions, formaldehyde is controlled below the allowable concentration, but the temperature of biological activity is generally 10 ~ 40 ° C, its use is subject to certain restrictions
