Description
Technical field
The present invention relates to a kind of composite long-acting formaldehyde scavenger and preparation method thereof
Background technology
The time of the most work of people, life all carries out indoor, and indoor environment greatly is related to the safe, healthy of people.But the creation of indoor environment be unable to do without ornament materials, and ornament materials is all relevant with chemical substance, and some chemical substance can give out toxic gas with different forms, different modes, pollutes, and wherein the formaldehyde pollutant is the most common.
Formaldehyde is the irritative gas of a kind of colourless, Yi Rong, belongs to noxious material, and high-concentration formaldehyde all has harm to nervous system, immune system, liver etc.It is the cellular plasm poisonous substance, and it can directly act on amino, sulfydryl and carboxyl, generates the methine derivative, thereby destroys body protein and enzyme, makes that histocyte takes place irreversiblely to solidify, necrosis; After inhaling people's high-concentration formaldehyde, the serious stimulation of respiratory tract and oedema, eye shouting pain, headache can appear, also bronchial astehma can take place, skin directly contacts formaldehyde, can cause dermatitis, color spot, necrosis, often suck a small amount of formaldehyde, can cause slow poisoning, mucous hyperemia appears, skin irritatin disease, allergic dermatitis, fragility, nail matrix finger tip pain etc. after the nail angling.Constitutional symptom have headache, weak, that stomach is received is poor, palpitaition, have a sleepless night, lose weight and vegetative nervous disorder etc.If content of formaldehyde is too high in the room air, eyes and skin all there is spread effect, if long-term contact, can make the people feel whole body discomfort, headache, dizzy, nauseating even can cause rhinocarcinoma, leukemia.This shows that formaldehyde serious threat arrives the health of human body, thereby has caused showing great attention to of people.
The formaldehyde amount is less than 0.08mg/m in " formaldehyde sanitary standard in the indoor air " regulation room
3, but concentration of formaldehyde average out to 0.2mg/m behind the general house decoration
3, reach as high as 0.81mg/m
3, seriously exceed standard.The processing that indoor formaldehyde is polluted at present adopts solid material to carry out physical absorption or chemisorbed to being released to airborne formaldehyde mostly, as existing active carbon, bamboo charcoal, plant extracts, polymer gel etc. on the market, though obtain certain effect, but use inconvenience, often change, cause secondary pollution.
Summary of the invention
The purpose of this invention is to provide the formaldehyde behind the permanently effective removal house decoration of a kind of energy, composite long-acting formaldehyde scavenger of non-secondary pollution and preparation method thereof.
Composite long-acting formaldehyde scavenger of the present invention, its composition and weight percent content thereof are:
6-O-CMC 5～10%
Urea 5～10%
Surplus is a water
The mentioned component sum is 100%.The deacetylation of said 6-O-CMC is greater than 90%, and the carboxylation degree is at 60%-70%, and weight average molecular weight is 200,000-500,000.
The preparation method of composite long-acting formaldehyde scavenger, its step is as follows:
Take by weighing 6-O-CMC and urea by prescription, 6-O-CMC and urea are dissolved in water respectively, by 1: 1 volume ratio two kinds of solution are mixed composite forming again.
Beneficial effect of the present invention is:
Shitosan is a kind of natural polysaccharide, safety that will be very in the use, have on the strand abundant amino can with the aldehyde radical generation chemical reaction of formaldehyde, thereby can remove the free formaldehyde that room internal cause finishing causes.But shitosan can not be water-soluble, can be dissolved in acetic acid.The acetum of shitosan has the tart flavour of intense stimulus, can cause discomfort to object and people's breathing.Adopt the 6-O-CMC, the carboxy methylation of its shitosan is on 6-O, the carboxylation degree is at 60%-70%, can be water-soluble fully, colorless and odorless, the deacetylation that guarantees shitosan simultaneously is more than 90%, guarantee that the N-position is not by carboxy methylation, a large amount of primary amino radical energy and formolite reaction are arranged, reactivity with height, the 6-O-CMC has good film forming, and its film and polar material such as timber, cotton fine, wallpaper have good adhesiveness, can close down in the object the outwards formaldehyde of slowly-releasing long-term effectively.The present invention also will be compound by little molecule urea and macromolecular polysaccharide, utilize micromolecular permeability and diffusivity, and the urea of part gos deep into catching free formaldehyde in it, realizes catching the quick-acting of formaldehyde.Composite long-acting formaldehyde scavenger of the present invention is with existing product active carbon, bamboo charcoal, plant extracts, polymer gel etc. are compared in the market, existing product is to adsorb automatically being released to airborne formaldehyde finite point, catch and kill and composite long-acting formaldehyde scavenger of the present invention is that large tracts of land is closed, its validity is more remarkable.
Permanently effective, the non-secondary pollution, safe and reliable of composite long-acting formaldehyde scavenger of the present invention, use very convenient, as long as the composite long-acting formaldehyde catching agent is coated on the body surface that body of wall, furniture, textile etc. might release formaldehydes.
