Abstract

The invention discloses a macromolecule formaldehyde scavenging agent. The macromolecule formaldehyde scavenging agent comprises 5 to 5% of high-molecular polymer, 1 to 5% of silicon dioxide, 1 to 10%of ammonium chloride, 4 to 12% of ammonium hydrogen sulfate, 1 to 7% of urea, 3 to 8% of cyanamide compounds, 1 to 5% of etidronic acid, 3 to 6% of plant extract and the balance water. The high-molecular polymer comprises at least one kind of carbodiimide according to the following formula (I): R'-(N=C=N-R)n-R''(I), wherein R represents an aromatic or aliphatic or alicyclic or aryl group alkylenegroup. According to the group, an aliphatic series or cycloaliphatic substituent group carrying three C atoms are carried on two ortho-positions or optional para-positions of an aromatic carbon atomcarrying a carbodiimide group under the condition of aromatic or aryl group alkylene residue; dissociated out formaldehyde in a material can be captured, the agent can permeate into the material to thoroughly remove non-releasing formaldehyde, the aim of permanently cleaning formaldehyde is achieved, and human body health is protected.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a polymer formaldehyde scavenger. Background technique [0002] The chemical formula of formaldehyde is HCHO, and the formula weight is 30.03. It is also called formaldehyde, a colorless gas with a special pungent smell, which is irritating to human eyes and nose. The relative density of the gas is 1.067 (air=1), the melting point is -92°C, and the boiling point is -19.5°C. Soluble in water and ethanol. Formaldehyde is one of the most important starting materials in the chemical industry. For example, it is used in the synthesis of urea-formaldehyde resin, melamine resin, phenol-formaldehyde resin, polyoxymethylene plastic and methylene biphenyl diisocyanate. Formaldehyde is also a precursor to functional alcohols such as pentaerythritol (used in paints and explosives). Other formaldehyde derivatives include methylene biphenyl diisocyanate (an important component in...
