Abstract

A formaldehyde scavenging composition, its preparation raw materials include: hydrophilic polymer, active inorganic material, polyester fiber, plant extract. The monomers for preparing the hydrophilic polymer include vinyl glucopyranoside, vinyl imidazole and vinyl pyrrolidone. The content of the vinyl glucopyranoside in the preparation monomer is 20-40wt%. The content of the vinylimidazole in the preparation monomer is 4-8wt%.

Description

technical field [0001] The invention relates to the field of environmental protection and energy saving, in particular to a formaldehyde removal composition and products. Background technique [0002] "Indoor air pollution" is the third pollution experienced by human society after "soot pollution" and "photochemical smog pollution". With the improvement of living standards, people pay more and more attention to the beautification and decoration of the living environment. Various decorative materials, such as artificial boards, decorative materials, decorative textiles, paints, wallpapers, etc. The formaldehyde pollutants caused also increase thereupon. The boiling point of formaldehyde is 19.5°C. It is a colorless gas with a strong pungent odor under normal conditions. It is easily soluble in water, alcohol and ether, and its volatilization speed increases with the increase of temperature. Formaldehyde is the number one "killer" of interior decoration, and has been identif...
