Problems solved by technology

Some react slowly with formaldehyde and have a low scavenging rate, such as some plant extracts; some have good effects, but are relatively toxic, such as Japanese patent: JP2001-164,235, which discloses a formaldehyde scavenger, and its specific components For: urea 25%, N-methylurea 5%, hydrazine 5%, formamide 1%, propylene glycol amine 1%, dibutyl succinate 2%, water 61%
It is mainly to reduce formaldehyde in wood-based panels, and the removal effect is good, but because it contains hydrazine, the toxicity is relatively high, and it is easy to cause secondary pollution

Abstract

The invention relates to a formaldehyde scavenger, which is used for scavenging a formaldehyde composition from an artificial panel and products thereof. The invention discloses a high-efficiency strong penetration type formaldehyde scavenger. The formaldehyde scavenger comprises a hydrazide compound, urea, an inorganic amine compound, a penetrant, a pH adjusting agent, water and the like. The product is non-toxic, smellless, safe, environment-friendly and strong in penetrability; the scavenger is coated on the exposed surfaces of various panels and furniture, can rapidly penetrate and scavenge free formaldehyde from the exposed surfaces, and has a lasting effect; and the scavenger can also be sprayed in the air so as to scavenge the free formaldehyde from the air. The scavenger has the advantages of simple production process and equipment, no three-waste pollution and low production cost.

Description

technical field [0001] The invention relates to a formaldehyde scavenger, which is used for removing formaldehyde composition in artificial boards and products thereof. technical background [0002] Formaldehyde is a common decoration pollutant. A variety of decoration materials and many daily consumer products will release formaldehyde. Formaldehyde is extremely harmful to the human body. It can react with human proteins to form aminomethylene compounds and change the properties of proteins, which can cause chronic poisoning, disease and allergic reactions, and also damage the genetic material in cells. At present, the formaldehyde pollution of interior decoration mainly comes from wood-based panels. Since most of the wood-based panels contain urea-formaldehyde resin, phenolic resin, melamine-formaldehyde resin, etc., these substances slowly release formaldehyde during use. Studies have shown that the release period of formaldehyde in wood-based panels is generally as long...
