Problems solved by technology

[0002] Many traditional formaldehyde removal products are pure chemicals. Although pure chemical products have a certain formaldehyde removal effect, they are harmful to the human body and cause secondary pollution.
[0003] In addition, there are some that rely on photocatalyst technology to remove formaldehyde, but it must be combined with ultraviolet light to have a better effect, and the use is cumbersome.
[0004] As a new formaldehyde removal technology, biological enzymes remove formaldehyde. It has the advantages of harmlessness, non-toxicity, no secondary pollution, and convenient use. However, the effect of biological enzyme products on the market is unstable. The main reason is that biological Enzymes are easy to inactivate, and the function of biological enzymes also requires a stable pH environment and a protective enzyme environment. The above-mentioned reasons have greatly affected their effects.

Abstract

The invention discloses a formaldehyde removing agent of biological enzyme. The formaldehyde removing agent of biological enzyme is prepared from the following components by weight percentage: 1 to 2% of biological enzyme composition, 1 to 3% of plant extract, 0.5 to 1% of protective agent, 1 to 2% of buffering agent, 0.1 to 0.3% of preservative, 0.1 to 0.3% of essence, the balance of water; thebiological enzyme is formaldehyde dehydrogenase, polyphenol oxidase and superoxide dismutase. The formaldehyde removing agent of biological enzyme is safe and non-toxic, harmless to humans and animals, and biodegradable and does not cause secondary pollution. The formaldehyde removing agent of biological enzyme is mainly used in indoor living environment and car to remove formaldehyde, can greatlyreduce the formaldehyde produced by furniture, leather, blankets and the like, and also has an effect of reducing benzene pollutants. The formaldehyde removing agent of biological enzyme has a long-lasting effect and has no corrosive effect on the surface of a treated object.
