Abstract

The invention relates to a formaldehyde capturing gel. The formaldehyde capturing gel comprises the following components in parts by mass: 0.3-0.9 part of nano Pb2O, 0.3-0.9 part of nano iron oxide, 0.1-0.5 part of nano calcium carbonate, 1-9 parts of nano nitrided titanium dioxide, 3-12 parts of octadecylamine, 3-10 parts of sodium metabisulfite, 25-35 parts of water, 20-30 parts of carbon tetrachloride, and 3-5 parts of a dispersing agent. The formaldehyde capturing gel provided by the invention has a good formaldehyde adsorption effect and long adsorption time, and can maintain high adsorption capacity after continuous action for 180 days, wherein the adsorption rate reaches 95% or more.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, in particular to a formaldehyde capture gel. Background technique [0002] The continuous large-scale development of construction real estate has created a large number of housing decoration needs, which has greatly aggravated indoor pollution. Statistics show that currently 68% of human diseases are related to indoor pollution, and formaldehyde is an important source of indoor pollution. The furniture, boards, carpets, paints and even adhesives that are inevitably used in home decoration all use formaldehyde as a component. These substances will volatilize formaldehyde more or less over time. pollution is inevitable. [0003] Formaldehyde capture gel is also known as formaldehyde scavenger, formaldehyde absorber or formaldehyde capture agent. Most of the current technologies are aqueous solutions containing compounds that can chemically react with formaldehyde under certain conditio...
