A kind of formaldehyde scavenger and application thereof

Abstract

The invention provides a formaldehyde scavenger, in particular to a formaldehyde scavenger with EGCG palmitic acid monoester as an active substance. Formaldehyde scavenger disclosed by the present invention, its component comprises by weight percentage: EGCG palmitic acid monoester 2-4%, polyethylene glycol 600 monooleate 1-3%, 1,3-propylene glycol 2-5%, Sodium dihydrogen phosphate 0.5‑2%. The EGCG palmitic acid monoester type formaldehyde scavenger disclosed by the invention is based on modified natural product active molecules, is green and environmentally friendly, has a stable and long-lasting aldehyde removal effect, and is suitable for removing formaldehyde in boards and furniture.

Description

technical field [0001] The invention relates to the field of formaldehyde removal, in particular to a formaldehyde scavenger using EGCG palmitic acid monoester as an active substance. Background technique [0002] Formaldehyde is a colorless and volatile toxic gas with irritating and suffocating properties. Its impact on human health is mainly manifested in abnormal sense of smell, irritation, allergy, abnormal lung function, abnormal liver function and abnormal immune function. The World Health Organization has identified formaldehyde as a carcinogenic and teratogenic allergy source, the International Agency for Cancer (IARC) has listed it as a first-class carcinogen, and my country has also listed it as a priority control list of toxic chemicals. [0003] At present, urea-formaldehyde resins, phenolic resins, melamine resins, etc. produced with formaldehyde as the polymerized monomer are widely used in density fiberboard, particleboard, plywood, paint-free board, In the p...

Problems solved by technology

[0006] In the disclosed technical solutions for eliminating formaldehyde, strong oxidants and acidic formaldehyde scavengers may corrode hardware and paint surfaces during use; most nuclear reagent type formaldehyde scavengers contain inorganic ammonium or organic amines or hydrazines, etc. Substances, such substances release toxic gases such as ammonia under certain conditions, thereby causing secondary pollution of indoor air; natural product type formaldehyde scavengers, such as tea extracts, such substances are used as a class of natural active substances with small toxic and side effects Because of the strong reactivity between the phloroglucinol building block and formaldehyde in its structure, there are many reports on the direct use of tea extracts to remove and control formaldehyde. However, due to the unique The polyphenolic hydroxyl structure makes it prone to oxidation, polymerization and other reactions under conditions such as light, high temperature, and humidity, so that its aldehyde removal activity quickly fails
