Abstract
The invention provides a kind of preparation method of the scavenging material to low concentration formaldehyde with detergent power, and mainly using ature of coal column-shaped active carbon as carrier framework material, 5% ~ 15% is loaded using equivalent impregnation method（Weight content）Amino acid, amino acid is glycine, control 40 ~ 55 DEG C or so of drying temperature, low temperature drying makes the material PARA FORMALDEHYDE PRILLS(91,95) of preparation have certain reactivity.The method applied in the present invention, that is, the suction-operated of activated carbon PARA FORMALDEHYDE PRILLS(91,95) is make use of, again using the reactivity of amino acid and formaldehyde, and cost is cheap has higher practical value.
Description
Technical field
The invention belongs to protective materials field, specially a kind of purifying formaldehyde material and preparation method thereof.
Background technology
Formaldehyde is a kind of common indoor pollutant, has the characteristics that source is wide, toxicity is big, the pollution time is long.Formaldehyde exists
It is a kind of organic solvent such as gas that is colourless, having intense irritation, soluble in water, alcohol, ether at room temperature.Formaldehyde in indoor air
Main source is kitchen fuel combustion and culinary art, smoking, house decoraton finishing etc., and its incubation period was up to 3 ~ 15 years as long as.Formaldehyde
Harm to human body depends on its concentration, stimulates eye mucous membrane at low concentrations, the upper respiratory tract is stimulated when concentration is slightly higher, causes cough
Cough, be uncomfortable in chest, having a headache and be nauseous, rhinitis, pharyngitis, pulmonary emphysema, lung cancer are caused when concentration is higher, in addition it is dead.Oneself is through by generation at present
Boundary's health organization is defined as carcinogenic and causes deformed material.The health problem brought of indoor environmental pollution triggered by formaldehyde is increasingly
The new focus attracted attention as the public.
The content of the invention
It is an object of the present invention to provide a kind of purifying formaldehyde material to low concentration formaldehyde with detergent power, with ature of coal column
Activated carbon is carrier framework material, by equivalent impregnation method, a certain amount of amino acid is added thereon, using the side of low temperature drying
Method, makes the material of preparation have higher adsorption capacity to low concentration formaldehyde.
The present invention adopts the following technical scheme that realization：
A kind of purifying formaldehyde material, using ature of coal column-shaped active carbon as carrier framework material, 5% ~ 15% is loaded using equivalent impregnation method
（Weight）Amino acid.The amino acid is glycine, histidine or glutamic acid.
The preparation method of above-mentioned purifying formaldehyde material：Amino acid is weighed by proportion, at normal temperatures stirs the amino acid weighed up
Mix and be dissolved into deionized water, uniformly poured into above-mentioned configuration good maceration extract on absorbent charcoal carrier with the method for equivalent impregnation,
And be stirred continuously, it is to be impregnated fully completely after, compound is loaded in hermetic bag, compound is placed in 40 ~ 55 after standing 1 ~ 4h
DEG C baking oven in dry, you can.
Compared with current material, the invention has the advantages that：
1st, the preparation method and approach of novel methylene scavenging material provided by the invention, has the work of suction-operated using PARA FORMALDEHYDE PRILLS(91,95)
Property charcoal as framework material, addition has reactivity and harmless amino acid with formaldehyde, makes the material of preparation to low
Concentration formaldehyde has higher adsorption capacity.
2nd, the method that the present invention is combined using absorption method with chemical method, adding PARA FORMALDEHYDE PRILLS(91,95) on the activated carbon has catalytic activity
And harmless amino acid, make the material of preparation there is higher adsorption capacity to low concentration formaldehyde, and do not cause two
Secondary pollution.
3rd, mainly absorption method, plasma technology, photocatalysis technology etc. of PARA FORMALDEHYDE PRILLS(91,95) purification in the market, single adsorption method
The adsorption efficiency of PARA FORMALDEHYDE PRILLS(91,95) is low and is also easy to produce secondary pollution, plasma technology, photocatalysis technology operating cost and maintenance cost compared with
Height, the method applied in the present invention, that is, the suction-operated of activated carbon PARA FORMALDEHYDE PRILLS(91,95) is make use of, utilize the reaction of amino acid and formaldehyde again
Activity, and cost is cheap has higher practical value.
