Problems solved by technology

[0004] The adsorption rate of activated carbon or some green plants is slow, and it is not obvious to remove formaldehyde or odor in newly decorated rooms for several months; due to the long release period of formaldehyde in the board, and the odor is restricted by space, time, airtight and other conditions, so Ventilation methods cannot completely eliminate formaldehyde pollution and odors; the third method is to use chemicals that react with formaldehyde or odors to eliminate them. The efficiency of eliminating formaldehyde or odors is high and thorough, and it is the fastest and most effective way to reduce formaldehyde or odors. Pollution methods, but chemical deodorants or deodorants are likely to cause secondary pollution. In order to create a clean, pollution-free, and pollution-free living environment, it is necessary to develop a natural plant-based formaldehyde scavenger to remove formaldehyde

Abstract

The invention relates to the technical field of formaldehyde and in particular to a natural plant type formaldehyde elimination agent and a preparation method thereof. The natural plant type formaldehyde elimination agent is prepared from the following raw materials in percentage by weight: 3-5% of persimmon tannin, 0.2-0.3% of a plant amino acid antibacterial agent, 1-4% of propylene glycol and the balance of water. The invention provides the natural plant type formaldehyde elimination agent and the preparation method thereof, and due to interactions of the persimmon tannin, the plant amino acid antibacterial agent, the propylene glycol, a polyphenolic substance with one amino acid at least, a stabilizer and a smell neutralizer substance, the prepared natural plant type formaldehyde elimination agent not only is good in formaldehyde removal effect and good in stability, but also has effects of bacterium inhibition and deodorization, and in addition is green and environment-friendly inthe formaldehyde removal process and free of secondary pollution in the formaldehyde removal process.

Description

Technical field [0001] The invention relates to the technical field of formaldehyde removal, in particular to a natural plant-type formaldehyde scavenger and a preparation method thereof. Background technique [0002] Formaldehyde is a colorless, irritating gas with a strong odor, which can be absorbed through the respiratory tract and has been identified as a suspected carcinogen and teratogenic substance by the World Health Organization. Formaldehyde can be combined with protein. After inhaling high concentrations of formaldehyde, severe irritation and edema of the respiratory tract, eye irritation, headache, and bronchial asthma may also occur. Direct skin contact with formaldehyde can cause dermatitis, stains, and necrosis; frequent inhalation of a small amount of formaldehyde can cause chronic poisoning, mucosal congestion, skin irritation, allergic dermatitis, nail keratosis and fragility, nail bed fingertip pain, long-term pregnant women Inhalation may cause deformities a...
