3The time, can cause throat discomfort or pain.When concentration is higher, the vomiting that can cause nausea, the cough uncomfortable in chest, asthma in addition pulmonary edema; Reach 30mg/m
3The time, meeting is the causing death immediately.Long Term Contact low dosage formaldehyde can cause chronic respiratory tract disease, women's menoxenia, pregnancy syndrome, causes that newborn infant's physique reduces, chromosome abnormalty, even causes nasopharyngeal carcinoma.High-concentration formaldehyde is all toxic to neural system, immunity system, liver etc.Formaldehyde also has teratogenesis, carcinogenesis.The people of Long Term Contact formaldehyde, may cause nasal cavity, oral cavity, nasopharynx, throat, skin and gastral cancer, in menoxenia and nuclear transgenation and the DNA strand crosslinked and DNA and protein cross and suppress the DNA damage reparation, pregnancy syndrome, cause neonatal chromosome disorder, leukemia, also can cause the decline of teenager's memory and intelligence.
In recent years, the environmental pollution that causes of formaldehyde oneself induce one pay close attention to widely.In the past, people adopt porous material (such as activated carbon etc.) to come the formaldehyde in the absorbed air usually, but this is a kind of administration way of passive type, and the time is longer, can not solve the problem of formaldehyde source of release at all.
People had invented some and had been referred to as the preparation of formaldehyde scavenger in recent years, wherein contain can with the composition of formaldehyde reaction.Patent CN101244362A for example, the application for a patent for invention that a kind of name is called " a kind of formaldehyde eliminating agent, have the plasterboard of function of eliminating formaldehyde " is disclosed, wherein mention with containing amino formaldehyde scavenger and come absorbing formaldehyde, because so aminoresin solidifies preparation liquor difficulty easily, so though its assimilation effect is good, but the speed that absorbs is very slow, can't a large amount of formaldehyde of transient absorption.CN2006100736 adopts amino acid to generate nontoxic product as the absorption agent of formaldehyde, but the product of amino acid after through spray absorber formaldehyde not easy-clear easily the outward appearance of furniture is affected.
Summary of the invention
The object of the invention is to for the defective of above-mentioned existence and a kind of formaldehyde scavenger and preparation method thereof is provided, take trimeric cyanamide as raw material, be very easy to and airborne formaldehyde reaction through the liquid aminoresin that produces after the liquefaction processing, PARA FORMALDEHYDE PRILLS(91,95) absorbs fast, overcome the slow-footed problem of formaldehyde absorption, and absorbing after product is aminoresin or the polymer that contains a large amount of amino, these materials are harmless, can effectively prevent from absorbing the secondary pollution that after product causes.
Technical scheme of the present invention is: a kind of formaldehyde scavenger, raw material comprises trimeric cyanamide, formaldehyde, 2-aminoisobutanol, lipid acid, Semen Maydis oil, wherein the weight ratio of trimeric cyanamide and formaldehyde is 1:1,2-aminoisobutanol content is 5% of trimeric cyanamide weight, and fatty acid content is 0.05% of trimeric cyanamide weight.
The preparation method of described formaldehyde scavenger may further comprise the steps:
(1) trimeric cyanamide in the raw material, formaldehyde are added in the reactor by weight 1:1, add entry and dissolve, then
The 2-aminoisobutanol that adds trimeric cyanamide weight 5%, regulating the pH value is 8, holding temperature is at 70～75 ℃ and be incubated 1 hour, obtains water white solution, and this solution is naturally cooled to room temperature, namely gets stable liquid aminoresin;
(2) in the prepared liquid aminoresin of step (1), add the lipid acid of trimeric cyanamide weight 0.05%, stir
Evenly;
(3) after liquid aminoresin and lipid acid stir, add again the Semen Maydis oil of 1ppm, add entry, stir namely
Can obtain this formaldehyde eliminating agent.
Beneficial effect of the present invention is: owing to contain a large amount of amino in the resulting liquid aminoresin take trimeric cyanamide as raw material after the process liquefaction processing, and be in unbound state, being sprayed in the air with Sprayable can be fast and airborne formaldehyde reaction, can directly wipe with the liquid that generates behind the formaldehyde reaction, or through after fixing after a while, but because the adding of releasing agent, so that a little less than the resin after solidifying contacts with furniture, very easily come off from furniture, can not cause furniture any such as apparent impact.The raw materials cost of this formaldehyde scavenger is lower, airborne formaldehyde in the highly effective decontamination chamber at short notice, also can carry out independent formaldehyde absorption to furniture processes, concrete grammar is about to the absorption agent sprinkling of gained or is coated to the surface of furniture, gets final product through after a while furniture being carried out the wiping cleaning.
