Abstract
The invention discloses a method for preparing super-absorbent resin through inverse suspension polymerization. The method comprises the following steps: aminoalcohol compounds are supported or not supported by the carrier and the product is used to remove free formaldehyde in the air. The used formaldehyde remover is non-toxic, is lower in dosage and in cost, and can not cause secondary pollution; and the removing speed of free formaldehyde is high, and the combination of aminoalcohol compounds and free formaldehyde is very stable so that formaldehyde can not be released to cause secondary pollution.
Description
Technical field
The present invention relates to a kind of is formaldehyde scavenger with serial alkamine compound, removes the method for free formaldehyde in the air on being carried on carrier or when using separately.
Background technology
Formaldehyde is the material than high toxicity, preferentially controls on the list formaldehyde at China's toxic chemical and is in second.Formaldehyde is confirmed as carcinogenic and teratogenesis shape material by the World Health Organization, is the allergen of generally acknowledging, also is one of potential strong mutagen.Research shows that formaldehyde has strong carcinogenic and short cancer effect.Formaldehyde mainly shows aspects such as allotriosmia, stimulation, allergy, abnormal pulmonary function, dysfunction of liver and immunologic dysfunction to health effects.Its concentration reaches 0.06-0.07mg/m in every cubic metres of air
3The time, slight asthma will take place in children.When formaldehyde in indoor air content is 0.1mg/m
3The time, peculiar smell and sense of discomfort are just arranged; Reach 0.5mg/m
3The time, can stimulate eyes, cause and shed tears; Reach 0.6mg/m
3, can cause throat discomfort or pain.When concentration is higher, the vomiting that can cause nausea, it is uncomfortable in chest to cough, asthma even pulmonary edema; Reach 30mg/m
3The time, meeting is the causing death immediately.In recent years, along with being rooted in the hearts of the people gradually of indoor decoration theory, the degree of interior decoration day by day strengthens; The kind of finishing material day by day increases; All used the raw material that contains formaldehyde in this wherein many material, and for the lower finishing material of some credit ratings, content of formaldehyde wherein is higher.These materials will slowly discharge its contained formaldehyde in the very long stage after finishing is accomplished, thereby will become the long-time pollution source of room air.
Based on this situation, the indoor free formaldehyde of many removings method and product be developed out.From the principle of its removing, can be divided into two types: the physics method is removed and chemical method is removed.So-called physics method, refer to formaldehyde scavenger only with air in free formaldehyde molecule generation physisorption, utilize physical surface absorption to catch formaldehyde, thereby reach the purpose that reduces indoor formaldehyde content.This series products generally all is the porous material of high-specific surface area, is the bamboo charcoal sold etc. like present market; The other product then adopts chemical method, and mostly existing market common chemical formaldehyde scavenger is the composite product of some titanium dioxide, and its main active ingredient is titanium dioxide, and assistant agent is dispersant, antifoaming agent, water etc.Its principle is to utilize the photocatalysis characteristic of titanium dioxide, under the situation of illumination, free formaldehyde molecule further is decomposed into harmless carbon dioxide and water.
Undoubtedly, above-mentioned two series products can reach absorption or degradation of formaldehyde molecule to a certain extent, alleviate the effect of room air pollution.But above-mentioned two series products also exist certain deficiency.Physics method absorbing formaldehyde be surface action power a little less than, absorption saturated concentration lower, adsorption rate is also slower; And be the chemical scavenger of active component with titanium dioxide; Then having the best photodissociation wave band of titanium dioxide is ultraviolet band; Activity is not strong under the radiation of visible light; Product reactivity correlative factor complicated (purity of titanium dioxide, granularity, concentration etc.), problems such as processed complex, constant product quality property difference.Therefore, developing effective free formaldehyde scavenger is a significant job.
Summary of the invention
The object of the present invention is to provide a kind of method of efficient absorption free formaldehyde, rapidly and efficiently to remove free formaldehyde.
The method of free formaldehyde is efficiently adsorbed in the present invention, and elder generation is with the alkamine compound load or be not carried on carrier, is used for removing the free formaldehyde of air then.
Described carrier is active carbon, porous aluminum oxide, silica, molecular sieve and diatomite.
Described alkamine compound is amido ethanol, 1-amido propyl alcohol, 2-amido propyl alcohol, 1-amino butanol, 2-amino butanol, 3-amino butanol, 2-methyl 2-amido-1,3 glycol and suc as formula a kind of of the compound shown in the I or several kinds.
R
1Be the hydroxyalkyl of carbon number 1-3, R
2, R
3, R
4And R
5Be carbon number 1-3 alkyl.
Free formaldehyde in the described removing air, required equilibration time is 2-24 hour.
The method of free formaldehyde is efficiently adsorbed in the present invention, and used formaldehyde scavenger itself is nontoxic, and consumption is less, and cost is lower, also can not cause secondary pollution; Fast to the free formaldehyde removing speed, combining of alkamine compound and free formaldehyde is highly stable, and release formaldehyde forms secondary pollution once more.
The specific embodiment
Embodiment
Test is at a 2.5M
3Square box in carry out, the air before experiment in the casing at first uses formaldehyde saturated, and suitably to adjust content of formaldehyde be that the effective dose of the each formaldehyde scavenger of certain value (about 0.6 mg/m3) is 50 milligrams.Method adopts the GB/T16129-1995 method, and is every at a distance from 0.5 hour once sampling, finally reaches formaldehyde absorption equilibrium (seeing table 1).
Table 1
By above-mentioned same procedure, (specific area is 800-1200M with active carbon
2, consumption is 2 grams) and for carrier, various alkamine compounds are carried on active carbon.
Table 2
Other carrier has also been done corresponding experiment described in the present invention, and its result and active carbon are similar, also belong within protection scope of the present invention.
