Description
Technical field
The invention belongs to indoor formaldehydes to administer field, and in particular to a kind of safety-type indoor formaldehyde agent for capturing and its preparation and
Application method.
Background technique
Indoor formaldehyde, especially new clothes interior content of formaldehyde of repairing the house are higher, and have that toxicity is big, source is wide and release time is long
The features such as, it is the main inducing of numerous diseases.Long Term Contact formaldehyde can cause headache, dizzy, out of strength, sensory disturbance, immunity
Reduction, failure of memory or neurasthenia, mental depression, or even respiratory dysfunction, hepatogenotoxicity lesion can be caused, increase suddenly
The probability of the special cancers such as odd gold lymthoma, Huppert's disease, myelomatosis, is determined as carcinogenic by the World Health Organization
And teratogen, China " Indoor Air Quality standards GB/T18883-2002 " provide that the concentration of formaldehyde in indoor air cannot be big
In 0.10 mg/m3.Pressing plank furniture, cortex or cloth sofa, carpet, curtain, wallpaper etc. are more common in indoor formaldehyde release,
To reach indoor formaldehyde governance standard, prevent formaldehyde from endangering, frequently with formaldehyde catching agent to indoor source of release and pollution air into
Row spraying is administered, and pollution can be effectively suppressed and discharge and eliminate air formaldehyde pollution, also have formaldehyde catching agent being directly added into building materials
For controlling formaldehyde pollution release in manufacturing process.
But as the improvement of people's living standards, the safeties such as toxicity, corrosivity of people's PARA FORMALDEHYDE PRILLS(91,95) agent for capturing itself are asked
Topic and its own color, smell etc. more pay close attention to the negative effect of domestic environment.In existing many reports, researcher
It is more concern formaldehyde catching agent function and have ignored demand of the consumer client to its color, smell, safety etc..Often
See problem such as ammonium salt decomposition bring peculiar smell and causes NH3Pollution, the pollution of acetyl compound bring organic volatile, sulfurous acid
Hydrogen sodium decomposes the SO caused2It pollutes, plant extracts (containing polyphenol) is mostly to be easy outside dyeing destruction after colored liquid sprays furniture
See etc..

Agent.
The formaldehyde condensation agent is food-grade built amino-acid, by L- glycine and L- taurine, L-Histidine, L- essence
Any one in propylhomoserin compounds.L- glycine and the matter of any one in L- taurine, L-Histidine, L-arginine
0.5~3:1 of ratio is measured, the purity of each amino acid is all larger than 99%.The compatibility can guarantee the formaldehyde catching of high capacity, and remain lower
Concentration of formaldehyde it is horizontal, > 99% purity requirement be then present after the impurity dissolution for avoiding bringing into amino acids production it is variegated.
The photocatalyst is the water-soluble nano titanium oxide of 3~5nm of partial size, and crystal form is Detitanium-ore-type.Water-soluble nano oxygen
Change titanium to be completely soluble in deionized water and then guarantee that implements surface does not have apparent solid particulate matter, anatase when spraying
The titanium oxide of type can guarantee under light action can effectively light degradation free formaldehyde and environment VOCs etc., having long-term reduces formaldehyde
The effect of pollution.
The condensation catalyst is food-grade soda ash (Na2CO3), sodium bicarbonate (NaHCO3One of), the two purity is big
In 99%.The catalyst can maintain agent for capturing aqueous solution pH in 7~9 weakly alkaline environments, accelerate amino acid condensation agent and formaldehyde
Reaction, it is softer to compare the strong alkaline substances basicity such as NaOH, not will cause the corrosion on implements surface layer.> 99% purity requirement is
Guarantee the high clarity of the aqueous solution of configuration.
The levelling agent is one of food level sodium carboxymethylcellulose, hydroxypropyl cellulose sodium, Sodium Polyacrylate.It should
Levelling agent can promote agent for capturing and spray dispersing uniformity after rear moisture evaporation on implements surface, be not in local solid spot
Point.
The antibacterial agent be one of poly hexamethylene biguanide aqueous solution, polyhexamethylene list guanidine aqueous solution, the two
Mass concentration is 10~30%.Antibacterial agent killing bacterium action concentration is extremely low, can work under 1ppm, has spectrum antibacterial
Effect, can kill it is common read coccus, staphylococcus, bacillus, mould etc., maintain using food grade materials agent for capturing it is long-term
Storage, and the microbiological contamination risk after spraying can be eliminated.
The present invention also provides the preparation methods of the safety-type indoor formaldehyde agent for capturing, comprising the following steps: will match
Each raw material just measured is mixed and stirred for making it completely dissolved in deionized water, and safety-type indoor formaldehyde can be prepared and capture
Agent.
Compared with prior art, a kind of safety-type indoor formaldehyde agent for capturing provided by the invention, has following advantages:
(1) grade-safe raw material is used, is mixed by formula rate, simple process；Colourless, tasteless, the nothing with postponing
Secondary pollution, is more suitable for indoor formaldehyde and administers construction using, and corrosion-free to tool face after spraying.
(2) agent for capturing uses compound amino acid to capture ingredient for the chemistry of formaldehyde, and green non-pollution is common compared to market
Modifiers, the capture ingredients that the present invention uses such as inorganic ammonium salt, organic amine (urea etc.), aniline and its derivatives, phenol are more pacified
Entirely, and without free ammonia it discharges, capturing ability is more powerful because introducing soda ash or sodium bicarbonate catalyst, effect.
(3) agent for capturing uses water-soluble nano titanium oxide, can cooperate with thorough light degradation formaldehyde, VOCs pollutant, and have
Long-term antibiotic property.
(4) for the agent for capturing configured after spraying application to implements surface, what is withheld after moisture evaporation is essentially particulate matter, it is ensured that
Implements it is dry and comfortable, do not have the bad sense of touch such as sticky.
(5) safety-type indoor formaldehyde agent for capturing formaldehyde removal capacity provided by the invention is excellent, through simulating 1m3Environmental chamber is surveyed
Examination, 0.8~1.1mg/m of initial concentration of formaldehyde3Under, this agent for capturing 20mL is sprayed to air, formaldehyde can be down in the cabin 20min
0.05mg/m3Hereinafter, removal rate > 95%；2 pieces are taken with quality 10cm × 10cm × 2cm pressing plank, in 0.125m3Environmental chamber
Test, the plank for not spraying agent for capturing, which stands concentration of formaldehyde in 4h rear deck, can rise to 0.6~0.7mg/m3, compare plate and exist
It is only 0.02~0.05mg/m that surface, which sprays this agent for capturing 2 times total 0.5mL and stands concentration of formaldehyde in 4h rear deck,3, rear concentration is tieed up for 24 hours
It holds constant.
(6) safety-type indoor formaldehyde agent for capturing usage mode diversification provided by the invention: can direct spraying released in formaldehyde
Source surface of putting such as furniture, sofa, curtain, carpet etc. is for inhibiting Form aldehyde release；It can directly be sprayed in formaldehyde pollution air fast
Speed eliminates formaldehyde pollution；Can be applied in combination with cold volatile-type air humidifier quickly reduces air formaldehyde concentration；And it can be with interior
Cascade landscape is applied in combination, which is added cascade, can quickly capture and absorb free of air formaldehyde.
