Abstract
The invention discloses a long-acting formaldehyde scavenging agent. The long-acting formaldehyde scavenging agent consists of main reaction agents, penetrating agents, catalysts and a solvent, wherein the main reaction agents are formamide and a polyol compound; the penetrating agents are fatty alcohol-polyoxyethylene ether and sodium dodecyl sulfonate; the catalysts are tartaric acid and sodium chloride; and the solvent is water. The long-acting formaldehyde scavenging agent disclosed by the invention is long in acting time, and the problem that the content of indoor formaldehyde rebounds and is gradually increased after the formaldehyde scavenging agent in the prior art is used for 1-3 days is solved, thereby reducing the economic load of a user and effectively reducing the condition that the content of indoor formaldehyde exceeds the standard because a user forgets to replace the formaldehyde scavenging agent so as to harm human health.
Description
Technical field
The present invention relates to a kind of formaldehyde scavenger, particularly action time is than long long-acting type formaldehyde scavenger.
Background technology
Formaldehyde has than high toxicity, is confirmed as carcinogenic and teratogenesis shape material by the World Health Organization, is the allergens that scientific circles generally acknowledge, also is one of generally acknowledged potential strong mutagen of medical circle.Can make human body sense of smell, PFT, liver function and immunologic dysfunction, and it also has stronger carcinogenic and short cancer effect.Long-term a small amount of contact formaldehyde can cause chronic respiratory disease, nasopharyngeal carcinoma, colon cancer, brain tumor, neonatal chromosome disorder and leukaemia etc.; Wherein, formaldehyde is maximum to children and pregnant woman's harm.
Owing to used urea formaldehyde resin adhesive, thereby can discharge formaldehyde in the artificial board (lumber core, density board, glued board etc.).In addition, manufacturing furniture, the decoration on metope, ground is laid, and all will use adhesive; Also can discharge formaldehyde.In a word, use the place of adhesive in a large number, generally all can have formaldehyde to discharge.So in the end section time after the house finishing, indoor formaldehyde content generally all can exceed standard, and the volatilization of formaldehyde is for up to 3-15; All not live the people more than 3 years and can not reach after the house finishing, some months people firmly just at most after the general finishing.
Therefore, all need take the whole bag of tricks to remove formaldehyde after the house finishing.There is following technological deficiency in formaldehyde scavenger of the prior art: in the 1-2 that has just brought into use days, can indoor content of formaldehyde be controlled under the national normal value; But generally indoor content of formaldehyde will rebound gradually and raise the formaldehyde scavenger that this just need more renew after 3 days.This can increase user's financial burden on the one hand; On the other hand, every at a distance from the formaldehyde scavenger that just need more renew in 2-3 days, if forget and will cause the indoor formaldehyde content overproof and influence health, make formaldehyde scavenger of the prior art unusual inconvenience in actual use.For example: the formaldehyde scavenger of certain brand is used to remove the formaldehyde that the finishing back produces; On-the-spot detection content of formaldehyde is 0.31 milligram every cubic metre; Every square metre is sprayed 20mL; Can make indoor formaldehyde content within 3 days, remain on 0.1 milligram below every cubic metre after the sprinkling, indoor formaldehyde content begins bounce-back and is increased to 0.1 milligram more than every cubic metre after 3 days.
Summary of the invention
To the deficiency that exists in the prior art, the object of the present invention is to provide a kind of action time of long long-acting type formaldehyde scavenger; Solve that formaldehyde scavenger of the prior art uses indoor formaldehyde content bounce-back after 1-3 days and the problem that raises gradually reduces user's financial burden, reduce effectively because of forgetting that the replacing formaldehyde scavenger causes the harm of indoor formaldehyde content overproof to health.
Technical scheme of the present invention is achieved in that the long-acting type formaldehyde scavenger, by main reaction agent, bleeding agent, catalyst and solvent composition.
Above-mentioned long-acting type formaldehyde scavenger, said main reaction agent is formamide and polyol compound.
Above-mentioned long-acting type formaldehyde scavenger, said bleeding agent are AEO and dodecyl sodium sulfate.
Above-mentioned long-acting type formaldehyde scavenger, said catalyst are tartaric acid and sodium chloride.
Above-mentioned long-acting type formaldehyde scavenger, said solvent are water.
Above-mentioned long-acting type formaldehyde scavenger; The percentage by weight of formamide is 10-15%, and the percentage by weight of polyol compound is 2-4%, and the percentage by weight of AEO is 0.1-0.3%; The percentage by weight of dodecyl sodium sulfate is 0.1-0.3%; Tartaric percentage by weight is 2-4%, and the percentage by weight of sodium chloride is 3-5%, and the percentage by weight of water is 72-80%.
Above-mentioned long-acting type formaldehyde scavenger; The percentage by weight of formamide is 12%, and the percentage by weight of polyol compound is 3%, and the percentage by weight of AEO is 0.2%; The percentage by weight of dodecyl sodium sulfate is 0.15%; Tartaric percentage by weight is 3%, and the percentage by weight of sodium chloride is 4%, and the percentage by weight of water is 77.65%.
The invention has the beneficial effects as follows: long-acting type formaldehyde scavenger of the present invention reaches more than 6 months action time, has solved thoroughly that formaldehyde scavenger of the prior art uses indoor formaldehyde content bounce-back after 1-3 days and the problem that raises gradually.Not only reduced user's financial burden; Can also reduce effectively because of forgetting that changing formaldehyde scavenger causes the harm of indoor formaldehyde content overproof to health, very convenient in actual use.
