Abstract
The invention discloses a formaldehyde absorbing agent. The formaldehyde absorbing agent is prepared from, by mass, 20-23 parts of tannin, 3-4 parts of diisopropylbenzene hydroperoxide, 15-18 parts of deacetylated chitin, 5-6 parts of iron white powder, 12-14 parts of calcium carbonate powder, 5-6 parts of barium stearate, 2-3 parts of 10, 10'-oxybis-phenoxarsine, 3-4 parts of acetylation diacid double starch sodium, 15-16 parts of nitromethane, 10-12 parts of aniline, 6-7 parts of edible seaweed powder, 8-9 parts of diatomite, 10-12 parts of nanometer titania, 5-6 parts of aluminium oxide and 60-62 parts of deionized water. The raw materials of the formaldehyde absorbing agent are subjected to a chemical reaction and a synergistic effect, and the formaldehyde absorbing rate is significantly improved compared with an existing formaldehyde absorbing agent; various functions of moisture absorption, deodorization, mildew and fungus resistance and the like are achieved, no secondary pollution is produced, the product is stable in performance, good in dispersity and long in storage time.
Description
Technical field
The present invention relates to a kind of formaldehyde absorbent and preparation method thereof, belong to air purification field.
Background technology
Along with the raising of expanding economy and living standards of the people, FASHIONHOME builds up in a large number, and indoor decoration is also more and more exquisite.In China's " Indoor Air Quality standards ", in regulation room, the maximum permissible concentration of formaldehyde is 0.10mg/m
3, most new finishing family after finishing completes in 5 ~ 10 months indoor formaldehyde concentration exceed standard several times to tens times, resident family adopts more passive window ventilation or the methods such as inhabitation again that wait for a period of time usually, causes very big inconvenience to life.
Formaldehyde has intense stimulus effect to human body skin and mucous membrane, eyesight and the selective damage of retina can be caused, can be there is dizziness, headache in Long Term Contact formaldehyde, weak, dry skin is broken, be losing one's memory, the neurasthenia symptom such as drowsiness, and formaldehyde is listed in carcinogenic substance, human body several types of cancers can be caused, cause the very big concern of society.
At present, the clean-up effect of dusty gas sorbing material as active carbon PARA FORMALDEHYDE PRILLS(91,95) be most widely used is poor, does not reach the requirement of purifying formaldehyde far away; Also someone utilizes plant absorption formaldehyde, the Purge gas such as bracketplant, sansevieria trifasciata, ivy, aloe, but this absorption unstable and infiltration rate is slow.
Summary of the invention
In order to solve the not high defect of the formaldehyde absorption efficiency existed in prior art, the invention provides a kind of formaldehyde absorbent and preparation method thereof.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is as follows:
A kind of formaldehyde absorbent; its raw material components comprises: tannic acid 20-23 part, di-isopropylbenzene hydroperoxide 3-4 part, chitosan 15-18 part, iron white powder 5-6 part, calcium carbonate powder 12-14 part, barium stearate 5-6 part, 10; the two phenoxazine arsenic 2-3 part of 10 '-oxo, the two sodium starch 3-4 part of acetylation diacid, nitromethane 15-16 part, aniline 10-12 part, edible seaweed powder 6-7 part, diatomite 8-9 part, nano titanium oxide 10-12 part, aluminium oxide 5-6 part and deionized water 60-62 part, described number is mass fraction.
The each raw material components of the application's formaldehyde absorbent is by chemical reaction and cooperative effect, and the mode PARA FORMALDEHYDE PRILLS(91,95) that products therefrom combines with chemisorbed and physical absorption adsorbs, and relative to existing formaldehyde absorbent, formaldehyde absorption efficiency significantly improves; And properties of product are stable, good dispersion, storage time are long.Above-mentioned chemisorbed refers to that the application's formaldehyde adsorbent portion of product can generate stability material with formolite reaction, and portion of product can impel Formaldehyde decomposition for Whom and carbon dioxide, non-secondary pollution.
In order to improve the chemisorbed performance of formaldehyde absorbent further, promote the cooperative effect between each component simultaneously, improve product reason absorption property, preferably, the raw material components of formaldehyde absorbent also comprises: nano TiO 2/tripolite composite catalyst 5-6 part, described number is mass fraction.
In order to promote the cooperative effect between each component further, improve the absorption property of product, preferably, the raw material components of formaldehyde absorbent also comprises: graphite powder 10-12 part, and described number is mass fraction.
In order to promote the cooperative effect between each component further, improve the absorption property of product, preferably, the raw material components of formaldehyde absorbent also comprises: hollow glass micropearl 3-4 part, and described number is mass fraction.
In order to improve formaldehyde absorbent chemisorbed performance further, promote the cooperative effect between each component, improve product reason absorption property, preferably, the raw material components of formaldehyde absorbent also comprises: p-phenylenediamine (PPD) 8-9 part, and described number is mass fraction simultaneously; Further preferably, the raw material components of formaldehyde absorbent also comprises: phenol 4-5 part, and described number is mass fraction.
In order to promote the cooperative effect between each component further, improve the absorption property of product, preferably, iron chloride 6-7 part, described number is mass fraction.
As a kind of preferred version of the application; the raw material components of above-mentioned formaldehyde absorbent comprises: 21 parts, tannic acid, di-isopropylbenzene hydroperoxide 3 parts, chitosan 16 parts, 5 parts, iron white powder, calcium carbonate powder 13 parts, barium stearate 6 parts, 10; the two phenoxazine arsenic 3 parts of 10 '-oxo, acetylation diacid two sodium starch 3 parts, nitromethane 16 parts, aniline 11 parts, 6 parts, edible seaweed powder, 9 parts, diatomite, nano titanium oxide 11 parts, 5 parts, aluminium oxide and deionized water 61 parts, described number is mass fraction.
The preparation method of above-mentioned formaldehyde absorbent, comprises the following steps that order connects:
