Description
Technical field
The present invention relates to environmental friendly indoor field, especially a kind of long-acting formaldehyde scavenger.
Background technology
In room air pollution, formaldehyde pollution is typically universal also intractable, during decorating house, by
In many artificial boards, binding agent, coating, paint, all contain formaldehyde, the dusty gass based on formaldehyde can be volatilized for a long time,
Human body is damaged.Formaldehyde is defined as carcinogenic and teratogenecity material by World Health Organization (WHO), and Long Term Contact formaldehyde can draw
Play chronic respiratory tract disease, pregnancy syndrome, the disease such as leukemia, neonatal chromosome disorder and teenager note can also be caused
Recall power to go down, mental retardation etc..Wherein artificial board is become with huge formaldehyde volatile quantity with up to the volatilization cycle of ten several years
High harm polluter the most obstinate in indoor pollutant.The air purifying process commonly used at present, mainly physical absorption, such as
Plant absorption and activated carbon adsorption；Wherein using during activated carbon adsorption, mainly activated carbon is prevented the dress in certain structure
Put, rely on the natural flow of air or the effect of blower fan to be adsorbed.But because formaldehyde is slowly to discharge for a long time, in room
Interior can not possibly place formaldehyde plant always, so formaldehyde still can constantly damage to human body.
Want really to solve the pollution problem of indoor formaldehyde, starting with from polluter is uniquely quick and permanently effective handss
Section.Indoor formaldehyde most serious and cycle the longest volatile source are various artificial boards.Find, common formaldehyde is clear through a large amount of tests
Except the very rare formaldehyde volatilization to artificial board etc. of method has a long-term remarkable result, exploitation is a kind of have long-term effect formaldehyde clear
Except agent is extremely urgent to solving the problems, such as Formaldehyde Pollution of Indoor Air.
Content of the invention
The present invention proposes a kind of formaldehyde removing product for the problems referred to above, and suppression wood-based plate that can be permanently effective etc. is stupid
Gu the formaldehyde volatilization of polluter, reduce indoor formaldehyde concentration, ensure home environment health.
To achieve these goals, the present invention using technical scheme is, a kind of long-acting formaldehyde scavenger includes a agent and b

During use, a, b agent is sufficiently mixed, brushes or be sprayed on the main formaldehyde volatile source such as wood-based plate exposed surface, consumption is
30～40ml/m, coats second time after first pass surface drying, and facing side coats one to two time, bare board face coating three to four
Time, can in rear repetitive coatings from January to March once if being necessary.
The concentration of 15 parts of described carbamide (ar) solution is 25～50wt%
The poly- aldehydes matter containing in the present invention such as gallic acid -1- epicatechol and gallic acid table times catechol are reacted in formaldehyde, can be fast
Speed effectively catches the free formaldehyde in sheet material, and it is steady that organic amine group can react generation hexamethylenetetramine etc. in formaldehyde for a long time
Determine compound, eliminate infiltration panel machine while formaldehyde and be configured to resin polymers, stop the continuation volatilization of formaldehyde.Final energy
Effectively reduce the content of the poisonous and harmful substance such as formaldehyde in family, lift home air quality.Through long-term follow test, the present invention
Described formaldehyde scavenger has persistently maintained 13 months so far to the formaldehyde evaporation retardation effect of wood-based plate bare board, instead
Bullet amplitude is very little, and general effect is more satisfactory.
