Abstract
The invention relates to a novel formaldehyde removing composite agent, with low cost, non secondary pollution and formaldehyde removing function. The inventive agent comprises at least one imidazolidinyl, at least one alkali compound and a solvent, wherein, the mass ratio between the imidazolidinyl and the alkali compound is 500:1-50:1, and the solvent mass is 0-99%. The inventive removing agentcan be uniformly dissolved in general aquosity or oil paint, with excitation on the human body. And the inventive agent can be dissolved into solution to be added into the processed decorative material, or be plated on the face of object and around air, therefore, the free imidazolidinyl in air and material is reduced under 0.08mg/m2 as national standard.
Description
Technical field
The present invention relates to a kind of novel formaldehyde removing agent composition.
Background technology
Along with China's rapid economy development, living standards of the people are improved day by day, and the house-purchase finishing has become inevitable.Contain a certain amount of formaldehyde or its unstable compound in some wood-based plates that use in the fitment process.Be subjected to the influence of environment, these materials finally can become formaldehyde gas be discharged into we around.Consequence behind this gas of absorption of human body is well-known.Therefore, develop a kind of novel methylene and dispel agent, harmless, also the indoor formaldehyde of non-secondary pollution is dispeled agent and is had important practical significance
The formaldehyde remover of having reported is a lot, as contains formaldehyde remover, the urea-containing formaldehyde remover of organic phenol and contain formaldehyde remover of ammonium class etc.; But there is following shortcoming in they: the range of application that has is narrow can influence coating property, a large amount of solvent extractions of the needs that have, slowly-releasing formaldehyde more still after the absorption that has.
Summary of the invention
Technical problem to be solved by this invention is: a kind of low cost of manufacture, non-secondary pollution will be provided, and can effectively remove the novel methylene removing agent composition of indoor formaldehyde.
For addressing the above problem, the technical solution used in the present invention is: a kind of formaldehyde removing agent composition, be characterized in: comprise following material: 5,5-methylimidazole alkyl diketone, at least a alkali compounds and solvent, and 5, the quality of 5-methylimidazole alkyl diketone and the mass ratio of alkali compounds are 500: 1～50: 1, and the consumption of solvent accounts for 0～99% of composition gross mass.

The invention has the beneficial effects as follows: formaldehyde remover of the present invention and free formaldehyde are combined into irreversible reaction, generate stable compound and represent with following structural formula:
And this compound also has good anti-mold effect.Its concrete advantage is as follows:
1, in newly-decorated indoor and furniture, spray a certain amount of this formaldehyde remover, can be very fast with air and furniture in the free formaldehyde effect, eliminate formaldehyde and reach national room air standard.
2, formaldehyde remover of the present invention joins in the finishing material, can reach the effect that reduces free formaldehyde.
3, formaldehyde remover of the present invention can be dissolved in the general water-based or oil paint uniformly.
4, formaldehyde remover of the present invention is to the human body nonirritant.
5, formaldehyde remover of the present invention adds in the pending ornament materials after being re-dubbed solution, perhaps is sprayed in body surface and the surrounding air, can make the free formaldehyde content of formaldehyde in air and in the processed material be lower than national standard 0.08mg/m
