Abstract
A formaldehyde capture for eliminating the free formaldehyde in air and decreasing the release of formaldehyde from artificial board is prepared from water, ammonium acetate, urea, sodium carbonate, sodium chloride, ammonium chloride and ammonium carbonate through proportional mixing.
Description
Technical field
The present invention relates to a kind of formaldehyde catching agent and preparation method thereof, belong to chemical technology field.
Background technology
In recent years, along with the increase of finishing use wood-based plate quantity, it is the problem that people pay close attention to that incident indoor formaldehyde pollutes always.Usually there is irritating smell to emerge in newly-decorated house, the chifforobe, Here it is poisonous gas---formaldehyde.Can stimulate the upper respiratory tract and the cornea of human body when formaldehyde reaches finite concentration, Long contact time more can reduce the immunity of human body, and especially the harm to old man, children and pregnant woman still is serious, can cause the sterile and neonate's deformity of pregnant woman.Therefore, purify the air of a room, reduce indoor formaldehyde pollution having become the task of top priority.Present domestic use air cleaning method has charcoal absorption technology and anion high pressure electrostatic precipitation technology.The charcoal absorption technology can only store nuisance absorption, and can not finally eliminate, and therefore will often change sorbing 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 elimination of indoor formaldehyde pollution.
Summary of the invention
Problems at above existence the purpose of this invention is to provide a kind of formaldehyde catching agent and preparation method thereof, thus airborne free formaldehyde and reduce the burst size of methanal of artificial board in the decontamination chamber, and then reach the IAQ standard of national regulation.
For achieving the above object, technical scheme of the present invention is:
This formaldehyde catching agent is to be mixed with by following raw materials by weight percent to form water: 55-75%; Ammonium acetate: 4-8%; Urea: 4-8%; Sodium carbonate: 13-26%; Sodium chloride: 0-2%; Ammonium chloride: 0-3%; Ammonium carbonate: 0-2%.
The preparation method of this formaldehyde catching agent may further comprise the steps:
1, gets the raw materials ready by the raw material of following weight ratio: water 55-75%; Ammonium acetate: 4-8%; Urea: 4-8%; Sodium carbonate: 13-26%; Sodium chloride: 0-2%; Ammonium chloride: 0-3%; Ammonium carbonate: 0-2%.
2, will more than get the raw materials ready to join respectively and evenly stir in the agitator, temperature is advisable at 3-28 degree centigrade, until dissolving.
3, discharging, filtration, packing are promptly made this formaldehyde catching agent.
The invention has the advantages that:
1, can react with formaldehyde rapidly, the release low-grade fever forms colourless transparent liquid (aqueous solution that contains hexa) 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 acid/mineral compounds, 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: 65 kilograms in water; 6 kilograms of ammonium acetates; 7 kilograms in urea; 20 kilograms of sodium carbonates; 0.5 kilogram in sodium chloride; 1 kilogram of ammonium chloride; 0.5 kilogram of ammonium carbonate.
2, will more than get the raw materials ready to join respectively and evenly stir in the agitator, temperature up to dissolving, forms transparent homogeneous liquid about 20 degrees centigrade.
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 smell, 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 1.8mg/ cubic meter before handling, and the amount of spraying is the 30ml/ cubic meter during processing, handles air concentration of formaldehyde＜0.08mg/ cubic meter in the wardrobe of back.
Example two:
At the two plates surface and the peripheral brushing product of the present invention of TPR plywood, detect the burst size of methanal of this plate then, inspection machine: QC-1 air detection instrument, 722 spectrophotometers, gas chromatograph; Testing conditions: 1 cubic metre of confined space, 20 degrees centigrade of temperature, 28%RH, testing result is as follows:
| Sequence number | Test item | Measurement unit | Testing result |
| ????1 | Be coated with sample sheet material after 24 hours formaldehyde release the amount sent out | The Mg/ cubic meter | ????0.05 |
| ????2 | Be not coated with sample sheet material after 24 hours formaldehyde release the amount sent out | The Mg/ cubic meter | ????0.26 |
Claims (4)
1, a kind of formaldehyde catching agent, it is characterized in that: with ammonium acetate, urea, sodium carbonate is primary raw material, with sodium chloride, ammonium chloride, ammonium carbonate a kind of, two or three prepare auxiliary material, then in order with major ingredient---join in an amount of water, evenly stir after abundant dissolving, again auxiliary material is joined respectively in the above-mentioned aqueous solution, evenly stir up to major ingredient and auxiliary material and all fully after the dissolving, make this formaldehyde catching agent through discharging, filtration, packaging process at last.
2, this formaldehyde catching agent according to claim 1 is characterized in that being mixed with by following raw materials by weight percent and forms: water: 55-75%; Ammonium acetate: 4-8%; Urea: 4-8%; Sodium carbonate: 13-26%; Sodium chloride: 0-2%; Ammonium chloride: 0-3%; Ammonium carbonate: 0-2%.
3, this formaldehyde catching agent according to claim 1, its preparation is, above ratio is got the raw materials ready to join in the agitator respectively in order evenly stir, and temperature is at 3-28 degree centigrade, up to abundant dissolving, make product of the present invention through discharging, filtration, packaging process then.
4, this formaldehyde catching agent according to claim 1, its using method is:
1), can directly be sprayed in the air that contains free formaldehyde.
2), can brush at TPR plywood, particieboard, core-board, medium density fibre board (MDF), compoiste wood floor and not on the surface of mopping, reduce the burst size of artificial board formaldehyde.
