Description
Technical field
The present invention relates to a kind of formaldehyde scavengers, and in particular to formaldehyde scavenger and preparation method thereof in a kind of film forming room.
Background technique
Formaldehyde is in the 2nd of China's toxic chemical priority acccess control list, has been determined as by the World Health Organization carcinogenic
With cause deformed material, be generally acknowledged allergen, and one of potential strong mutagen, and be considered and leukaemia is sent out
There is causalities between life.Excessive formaldehyde can generate apparent stimulation to eyes, respiratory tract, human body mucous membrane and skin and make
With；Acute poisoning can lead to shed tears, runny nose, the symptoms such as cough, cause various respiratory tract disease；Chronic inhalation of low concentration can lead to
Unrelenting headache, inability, insomnia etc.；Long-term sucking low dosage can cause chronic respiratory disease, feminine menstrual disorder, neonate
Matter reduction, chromosome abnormality, or even induce nasopharyngeal carcinoma；The mouths such as nervous system, liver of meeting infringer when high concentration.
Indoor formaldehyde is mainly derived from glued board, fine workmanship's template, medium density fibre board (MDF) and the particieboard, wooden core that finishing uses
The artificial boards such as plate.These finishing materials are primarily due to use aldehydes polymer resin binder --- Lauxite, at present
Such plate is in house ornamentation occupation rate of market up to 80% or more, but the adhesive feature is after deliquescing or room temperature meeting when being more than 20 DEG C
Free formaldehyde is decomposited, is the main reason for causing Formaldehyde Pollution of Indoor Air.
To solve the problems, such as Formaldehyde Pollution of Indoor Air, various formaldehyde scavengers, especially photocatalyst are had studied both at home and abroad and its is answered
Mould assembly aldehyde remover report is especially more.CN201510181982.3 has invented cold catalyst (carrying platinum nanometer rutile titania titanium dioxide) 1-8%；
Nano-silver colloid 0.1-0.5% and amphipathic fibroin albumen 5-15%；Ethylene urea 5-10% compounding can reach except aldehyde at 24 hours
To except aldehyde rate 97.9%；CN201611143931.2 has invented a kind of antistatic low-light light touching type formaldehyde scavenger and its preparation side
Method, by modified aqueous polyurethane emulsion (Acrylate Modified Aqueous Polyurethane multiple emulsion) 35%, water soluble Beta-cyclodextrin 8%, carboxyl
SBR modified latex 9.5%, antistatic agent (ethyoxyl laurel ester amine) 5%, Formaldehyde decomposition enzyme 7%, aqueous hyper-dispersant (aqueous light
Quick polyurethane hyper-dispersant) 6%, nano-stephanoporate silicon dioxide 0.5%, n-butanol 3% and stabilizer (HH972-2) 1% compounded,
It can reach at 1 hour except aldehyde rate > 40%；CN201610571870.3 has invented a kind of photocatalyst type formaldehyde scavenger and its system
Preparation Method, 1-10% nanometer silver paste solution, the photocatalyst (nanometer anatase titania colloidal solution) of 1-15%, 0-5% lauroyl
Base glutamic acid surfactant, 0-5% polyethylene glycol, formaldehyde catching agent (the 2- imidazolidinone, 1,3- diaminourea and two of 1-8%
Methylacetamide), remaining deionized water.But the aldehyde remover of photocatalyst is at high cost, and very strong to light dependence, practical application effect
Fruit is general, and it is more difficult to promote.
Formaldehyde is once evaporate into air, it is more difficult to be captured, even if using most effective formaldehyde scavenger, if contact is not
To formaldehyde, or in the case where concentration of formaldehyde is especially low, except aldehyde performance is all excessively poor, formaldehyde is only removed into ability in source
Reach really except aldehyde.In order to find better formaldehyde adsorbent or agent for capturing, contact formaldehyde scavenger preferably with formaldehyde.
CN02113857 invents a kind of novel methylene oxide scavenging agent with the halide of hydrazides substance and metal, nitrate, sulphite etc.
Substance is as aldehyde remover, and assist infiltration agent, carries out capture elimination mainly for artificial board inside release free formaldehyde, but at
Type furniture surface applies matcoveredn, and addition bleeding agent effect is smaller, it is more difficult to give full play to it except aldehyde performance.
CN201610784900.9 invents a kind of furniture formaldehyde scavenger that percdation surface layer persistently captures and preparation method, using end
Amino dissaving polymer 1-5%, Carboxymethyl chitosan 5-10%, bleeding agent (fatty alcohol polyoxyethylene ether compound) 0.1-
1%, buffer (phosphate buffer, phthalate buffer, citrate buffer solution) 0.1-1%, coalescing agent (propylene glycol
Butyl ether, propylene glycol methyl ether acetate) 0.1-1%, balance deionized water.The patent is mainly removed using Carboxymethyl chitosan
Aldehyde, it is at high cost, except aldehyde efficiency is general.CN201610661461.2 invents a kind of high-efficiency formaldehyde scavenging agent, with trihydroxy methyl ammonia
10-20 parts of methylmethane, 5-15 parts of saleratus, bleeding agent (sulfated castor oil, sodium alkyl sulfonate, sodium alkyl benzene sulfonate, amber
Acid alkyl ester sodium sulfonate, sulfamic acid sodium, fatty alcohol polyoxyethylene ether and alkyl phenol polyoxyethylene ether) 2-5 parts, film forming agent it is (poly-
Ethylene, polyurethane, acrylic resin, acrylate modified butadiene resin) 3-6 parts, 4-6 parts of ammonium hydroxide, extract solution from aloe 5-15
Part is main component, and wherein ammonium hydroxide smell is larger, is not suitable for interior use, extract solution from aloe higher cost, and saleratus is stablized
Property is poor.
The prior art can't be fully solved the problem of Formaldehyde Pollution of Indoor Air, and it is clear to need to develop a kind of good film-forming property, formaldehyde
Except high-efficient and low-cost formaldehyde scavenger.
