Description

A kind of formaldehyde adsorption material and preparation method thereof
Technical field
The invention belongs to Techniques for Indoor Air Purification field, specifically a kind of formaldehyde adsorption material and preparation method thereof.
Background technology
Formaldehyde is irritative gas that is colourless, that have overpowering odor, its aqueous solution of 35% ~ 40% common name formalin.Formaldehyde is magma poisonous substance, can and protein bound, suck after high-concentration formaldehyde, there will be the serious stimulation of respiratory tract and oedema, eye shouting pain, headache, also bronchial astehma can occur.Direct skin contact formaldehyde, can cause dermatitis, color spot, necrosis.The a small amount of formaldehyde of frequent suction, slow poisoning can be caused, occur mucous membrane hyperemia, skin irritatin disease, allergic dermatitis angling and fragility, nail matrix finger tip pain, pregnant woman sucks for a long time and may cause ewborn infant deformity, even dead, man sucks for a long time and can cause man's teratospermia, death, property function reduction, serious caused leukaemia, pneumothorax, fecundity lacks, and that constitutional symptom has headache, weak, stomach is received is poor, palpitaition, have a sleepless night, lose weight and vegetative nervous disorder etc.Various artificial board (owing to employing urea formaldehyde resin adhesive in particieboard, density board, fiberboard, glued board etc., thus can contain formaldehyde.The making of new-type furniture, the decoration on metope, ground is laid, and all will use adhesive.The place of every a large amount of use adhesive, always has Form aldehyde release.In addition, some chemical fibre carpet, paint are also containing a certain amount of formaldehyde.So after the interior decorations such as family, hospital, school, need the minimizing, the Processing for removing that carry out formaldehyde.
The method of this kind of harmful substance of current removal mainly comprises: one is physisorphtion, as loose structure, large specific area that active carbon has, by formaldehyde absorbing on material to remove formaldehyde, though but the not high needs of active carbon price often change.Two is chemical methodes, and chemical classes air treating product is mainly obtained by Prof. Du Yucang mode, is much wherein aromatic compound.Aromatic compound is nearly all containing to be proved to be or suspected of the benzene ring compound of carcinogen.Three is the products adopting photocatalysis principle, and coat some catalyst on the adsorbent material, utilize the oxygen in sunlight and air oxidation of formaldehyde to be fallen, photocatalyst is in the market exactly this series products, and the control expense of every square metre about about 20 yuan, price is more expensive.Four is plant methods, and a lot of plant has the function absorbing the pernicious gases such as formaldehyde, as bracketplant, sansevieria trifasciata, ivy, aloe etc., be other materials by formaldehyde conversion, but this absorption instability and to deal with speed slow.Above-mentioned material and method all have certain effect to removing formaldehyde, but yet there is the easily limitation such as absorption is saturated, reproducibility is poor, use cost is high.
Summary of the invention
Technical problem to be solved by this invention is to provide that a kind of preparation technology is comparatively simple, suction-operated is strong, easy to use and cost is low, the environmental formaldehyde gas sorbing material of nonhazardous.The present invention uses the mechanism of multiple Adsorption and decomposition formaldehyde, and thoroughly, discomposing effect is good, and has the advantage that preparation method is simple, cost is low in absorption.、
Technical scheme of the present invention is as follows:
A kind of formaldehyde adsorption material, be made up of the raw material of following percentage by weight:
Tannin: 5 ~ 15%
Collagenous fibres: 10 ~ 20%,
Crosslinking agent: 1 ~ 5%,
Shitosan: 2-10%
Bleeding agent: 0.1-3%
Surfactant: 0. 3-3.2%
PH adjusting agent: 0. 15-1. 0%
Water: surplus
Described tannin is one or more arbitrary proportions mixing of persimmon tannin or fruit of date plum tannin, and described surfactant is stearic acid, the one in neopelex.
Remove a sorbing material for indoor formaldehyde gas, its preparation method comprises the steps:
(1) in the distilled water being heated to 55 ~ 60 °, tannin, collagenous fibres, shitosan, bleeding agent, surfactant and pH conditioning agent is added, stirring and dissolving,
(2) add crosslinking agent, regulate pH to 4 ~ 5;
(3) by the heating water bath 2 ~ 3 hour of step (2) gained reactant at 40 ~ 60 DEG C, stirring is cooled to room temperature and namely obtains product.
In the soluble in water and polar organic solvent of tannin, is therefore difficult to the process being directly used in formaldehyde waste liquid or gas, and is thisly solidificated in the suprabasil persimmon tannin of collagenous fibres by glutaraldehyde, there is the feature of water insoluble and multiple organic solvent; Recording its thermal denaturation temperature with differential scan calorimeter (DSC) is 156 ~ 175 DEG C, and namely have good heat endurance, service condition is temperature influence not; As adsorbent because its source is animals and plants composition, and can not to environment; It also have with low cost, adsorption rate is fast, capacity is large; A kind of new and effective sorbing material having the prospect of marketing, the removal of the formaldehyde gas volatilized by ornament materials, furniture, floor etc. after can being widely used in indoor particularly house decoration.
Can be there is condensation reaction and generate Schiff 's base in the active amido on shitosan C2 position and the carbonyl of formaldehyde, can use as the remover of formaldehyde in fur.The industrial synthesis having utilized this character to carry out chitosan resin.Relative to chitin, shitosan dissolubility is good, can dissolve under mildly acidic conditions, in the solution abundant and formolite reaction.Containing a large amount of-NH2 and-OH in chitosan molecule, good with the affine performance of fiber, can fibrous inside be added to, be combined with hydrogen bond or covalent bond with-NH2 with fibrous active radical-OH, go deep into fibrous inside and remove formaldehyde.
The invention has the beneficial effects as follows: preparation technology of the present invention is comparatively simple, suction-operated strong, and easy to use and cost is low, the shitosan that adds, tannin can there is larger reaction with formaldehyde, more in depth can remove formaldehyde gas, efficiency is high.
