Description

A kind of method that artificial board removes formaldehyde
Technical field
The invention belongs to environmental protection technical field, and in particular to a kind of method that artificial board removes formaldehyde.
Background technology
Poisonous and harmful substance is mainly derived from the pollutants such as formaldehyde, ammonia that building and ornament materials are discharged.Formaldehyde is higher The material of toxicity, formaldehyde is in second on China's toxic chemical priority acccess control list.Formaldehyde is by world health group Knit and be defined as carcinogenic and cause deformed material, be also one of potential strong carcinogen.Long Term Contact low dosage formaldehyde can cause chronic Breathing problem, causes nasopharyngeal carcinoma, colon cancer, brain tumor, pregnancy syndrome, causes neonatal chromosome disorder, leukaemia, causes Teenager's memory and intelligence decline.In all contactees, children and pregnant woman's PARA FORMALDEHYDE PRILLS(91,95) are particularly sensitive, endanger also just bigger. Counted according to related data and shown：The mankind have 70% illness relevant with indoor environment, and China has 120,000 people to die from indoor dirt every year Dye, more than 90% child leukaemic all live in new clothes repair the house it is ill in 1 year.
Most of formaldehyde are present in the made wooden boards of finishing.Various wood-based plates, such as density board, gluing Plate, core-board etc., using urea formaldehyde resin adhesive, Lauxite inevitably remains part trip during glue From formaldehyde, outwardly distribute.In addition, Lauxite also generates a small amount of linear resin in preparation process, in long-term use During, it is also possible to free shape formaldehyde is resolved into, is also outwardly distributed, very big infringement is caused to human body.
The method of current elimination formaldehyde, one is to reduce the formaldehyde in adhesive, but this method can not possibly be completely eliminated Formaldehyde, unlikely eliminates the formaldehyde in linear resin.Therefore, remove not thorough.Two is to use the adhesive without formaldehyde, but This adhesive it is relatively costly.
The content of the invention
To solve the above problems, the present invention provides a kind of method that artificial board removes formaldehyde, and removal effect is good, low cost, Process is simple, can eliminate the formaldehyde in linear resin.
What the present invention was achieved through the following technical solutions：
A kind of method that wood-based plate removes formaldehyde, comprises the following steps：
（1）Artificial board is placed in closed space, nitrogen is passed through, spray solution A to humidity is 30-60%, is heated to 60-70 DEG C, it is incubated 2-4 hours；
（2）It is 10-15% to dry to humidity, is incubated 1-2 hours；
（3）Vacuumize, be cooled to 30 DEG C, be incubated 2-5 hours；
（4）Artificial board spray solution B, is warming up to 40-50 DEG C, is incubated 0.5-2 hours, then is cooled to 25-30 DEG C, drying.
Heating not only promotes the volatilization of free formaldehyde, it is also possible to promote the fracture of unstable linear resin chain, formaldehyde is released Release, while heating also promotes the reaction of solution and formaldehyde, generating structure stabilization, environmentally safe material.
Preferably, the step（1）Middle solution A be amino acid, ethylenediamine tetra-acetic acid, Dodecyl Polyglucosides, Tea Polyphenols, The mixed aqueous solution of ammonium phosphate and 1, 8-Cineole, concentration is 0.1-1g/L.Wherein, amino acid, ethylenediamine tetra-acetic acid, dodecane The mass ratio of base glucoside, Tea Polyphenols, ammonium phosphate and 1, 8-Cineole is 1：1-3：2：1：2：0.5.
Preferably, the step（4）In solution B be epoxychloropropane modified polyethyleneimine and stryrene divinyl The mixed aqueous solution of base benzene EVA.Wherein, the matter of polyethyleneimine epoxychloropropane and styrene-divinylbenzene copolymer Amount is than being 1-5:10, the concentration of solution is 0.05-0.5g/L, and regulation pH is 5-6.
Styrene-divinylbenzene copolymer is soluble in water, transparent solution, and ten thousand/several mass fraction is have to kill The ability of bacterium sterilization, it is non-stimulated to skin, it is non-toxic, metal is not corroded, even if also stablizing in boiling water, its sterilizing ability with PH value is raised and increased.Additionally, it also has good foamability.
The method of epoxychloropropane modified polyethyleneimine, increased the content of acidic-group, and acidity is improved, and hydrophily is carried It is high.Formaldehyde absorption with formaldehyde reaction, is generated one layer of diaphragm of stabilization by solution, and protection is played a part of to sheet material.
Preferably, step（1）The speed of described heating is 10-20 DEG C/h, step（4）Described heating rate is 10- 15℃/h。
