Abstract
The invention relates to a formaldehyde remover and its preparation method, belonging chemical industry technical field. The formaldehyde remover is prepared from following raw materials through uniformly stirring and mixing according to the weight percentage, including: 50-85% of water; 0-12% of citric acid, 0-3% of ammonium carbonate, 0-15% of ammonium chloride; 2-10% of ammonium acetate and 3-10% of urea. The formaldehyde remover is mainly used for reducing the release amount of formaldehyde in the artificial plate, removing the formaldehyde pollution after interior decoration and protecting people body health. After spraying 35ml formaldehyde remover in each cubic meter air, the free formaldehyde concentration is lower than 0.08mg/cm3 in the indoor air, thereby the free formaldehyde content in the indoor air reaches national standard.
Description
Technical field
The present invention relates to a kind of formaldehyde remover and preparation method thereof, belong to chemical technology field.
Background technology
In recent years, a large amount of wood-based plates are applied to interior decoration, and it is the problem that people pay close attention to that incident indoor formaldehyde pollutes always.It is the main inducing of cancer, respiratory tract disease, leukemia, immunity reduction, fetus teratogenesis etc., has had a strong impact on the people's physical and mental health and orthobiosis.Therefore, purify the air of a room, become the task of top priority.The method that present domestic use purifies the air of a room has activated carbon adsorption technology, anion high pressure electrostatic precipitation technology etc.The activated carbon adsorption technology can only store nuisance absorption, and can not finally eliminate, and therefore will often change adsorbing material, and is very inconvenient.And the anion high voltage electrostatic technique is a kind of physical action process, and what can remove is airborne flue dust, but not obvious to the removal of indoor formaldehyde pollution; Secondly its cost height needs electricity consumption during use, can produce noise, is unfavorable for a large amount of penetrations and promotions.
Summary of the invention
At the problems of above existence, the purpose of this invention is to provide a kind of formaldehyde remover and preparation method thereof, thereby remove free formaldehyde and the burst size of methanal that reduces artificial board in the room air, and then reach the IAQ (indoor air quality) standard of national regulation.
For achieving the above object, technical scheme of the present invention is:
This formaldehyde remover is to be mixed with by following raw materials by weight percent to form water: 50-85%; Ammonium citrate: 0-12%; Ammonium carbonate: 0-3%; Ammonium chloride: 0-15%; Ammonium acetate: 2-10%; Carbamide: 3-10%.
The preparation method of this formaldehyde remover may further comprise the steps:
1, gets the raw materials ready by the raw material of following weight ratio: water: 50-85%; Ammonium citrate: 0-12%; Ammonium carbonate: 0-3%; Ammonium chloride: 0-15%; Ammonium acetate: 2-10%; Carbamide: 3-10%.
2, will more than get the raw materials ready to join respectively and evenly stir in the agitator, until abundant dissolving.
3, discharging, filtration, packing are promptly made product of the present invention.
The invention has the advantages that:
1, can react with formaldehyde rapidly, the release slight fever forms colourless transparent liquid (aqueous solution that contains hexamethylenetetramine) nontoxic, excellent stability.
2, by with formaldehyde neutralization reaction fast and efficiently, eliminated in the air free formaldehyde and reduced the burst size of formaldehyde in the artificial board, pollute thereby solved the formaldehyde after the interior decoration, help the healthy of people.
3, the pH value of this product is neutral aqueous solution, and no corrosiveness can not have infringement to plank or the article that spray.
4, the present invention is made up of nontoxic material, can not damage the person.
5, the cost of raw material of the present invention is low, and production technology is simple, and is easy to use.
Specific implementation method:
1, gets the raw materials ready by following weight ratio: water: 73 kilograms; Ammonium carbonate: 1 kilogram; Ammonium citrate: 5 kilograms; Ammonium chloride: 3 kilograms; Ammonium acetate: 8 kilograms; Carbamide: 10 kilograms.
2, will more than get the raw materials ready to join respectively and evenly stir in the agitator, up to abundant dissolving, form transparent homogeneous liquid.
3, discharging, filtration, packing are made pH value for neutral, and the aqueous solution of transparent homogeneous is a product of the present invention.
Below in conjunction with embodiment effect of the present invention is described:
Example one:
Behind finishing, indoor wardrobe, wardrobe free formaldehyde concentration are big, dazzling pungent, the thorn larynx of abnormal smells from the patient, so that draw tears from sb, cough.Spray the wardrobe inwall with product of the present invention.The interior air concentration of formaldehyde of wardrobe is the 2.5mg/ cubic meter before handling, and the amount of spraying is the 35ml/ cubic meter during processing, handles air concentration of formaldehyde＜0.08mg/ cubic meter in the wardrobe of back.
Example two:
Product of the present invention is sprayed on two surfaces at two 0.5 square metre TPR plywood, treat to put into after nature dries the airtight test chamber (volume is: 1.5 cubic metres) that is marked with 0.74Mg/ cubic meter formaldehyde, the content of formaldehyde in the sampling Detection test chamber at times then, inspection machine: QT-2 air sampler, 722 spectrophotometers; Testing conditions: 1.5 cubic metres of test chambers, testing result is as follows:
Claims (4)
1, a kind of formaldehyde remover and preparation method thereof is characterized in that: the aqueous solvent that mainly consists of carbamide and ammonium citrate, ammonium chloride.
2, this formaldehyde remover according to claim 1 is characterized in that being mixed with by following raw materials by weight percent and forms: water: 50-85%; Ammonium citrate: 0-12%; Ammonium carbonate: 0-3%; Ammonium chloride: 0-15%; Ammonium acetate: 2-10%; Carbamide: 3-10%.
3, this formaldehyde remover according to claim 1, its preparation is, above ratio is got the raw materials ready to join in the agitator respectively evenly stir, and up to abundant dissolving, makes product of the present invention through discharging, filtration, packaging process then.
4, this formaldehyde remover according to claim 1 is characterized in that:
1) can react rapidly, discharge slight fever, form the colourless transparent liquid of excellent stability, and this liquid is placed the rear surface for a long time and had a spot of colourless fractionlet thin film generation with formaldehyde.
2) can eliminate formaldehyde in the artificial board (not mopping), and form colourless fractionlet thin film, and then stop that formaldehyde outwards discharges on the surface of artificial board.
3) pH value is neutral, and this solvent temperature is lower than general aqueous solution.
