Compound formaldehyde scavenger

Abstract

The invention provides a compound formaldehyde scavenger. The compound formaldehyde scavenger is composed of, by weight, 3-5% of imidazolidone or imidazolone or a mixture of imidazolidone and imidazolone, 2-3% of urea, 1-2% of a metal chloride, and the balance water. The compound formaldehyde scavenger can purify air quickly, efficiently and enduringly, and is nontoxic, tasteless, safe and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of formaldehyde elimination, and in particular relates to a composite formaldehyde scavenger. Background technique [0002] The chemical formula of formaldehyde is HCHO. It is a colorless gas at normal temperature and has a special pungent smell. Due to its special chemical properties, it is widely used in the chemical industry and fur industry. [0003] In industry, adhesives such as urea-formaldehyde resin glue, melamine resin glue and phenolic resin glue all use formaldehyde as the main raw material, and these adhesives are widely used in the production of boards such as plywood, joinery board and density board. In addition, such adhesives are used in the walls and floors of buildings, in the finishing of furniture and in auxiliary equipment. [0004] In the fur industry, formaldehyde tanning agent is a widely used post-treatment agent, which can make the leather color pure white, does not change color w...

Problems solved by technology

For example, the adsorption products are easy to be saturated, and the adsorption of pollutants is not reliable, and it is easy to volatilize again; the ozone purification speed is fast but the sustainability is poor; the common formaldehyde scavenger has low removal efficiency and poor sustainability; air purifiers occupy space and consume resources
