Abstract
The invention relates to the technical field of melamine adhesives, particularly a melamine adhesive formula for absorbing and decomposing formaldehyde in air and a preparation technique thereof. The melamine adhesive is composed of the following components in percentage by weight: 35-48% of formaldehyde, 28-32% of melamine, 3-7% of diethylene glycol, 7-15% of water, 3-7% of amine, 0-1% of sodium hydroxide, 4-7% of aldehyde remover and 0-5% of nano silicon dioxide. The preparation method comprises the following steps: sequentially adding formaldehyde, melamine, diethylene glycol, sodium hydroxide, aldehyde remover, nano silicon dioxide and amine into a preset weight of water, and stirring. Compared with the prior art, the furniture, floor board and decorative board using the melamine adhesive have the capacity for eliminating formaldehyde in air, and have high formaldehyde removal efficiency; the melamine adhesive is suitable for operation of the existing plant production equipment; and the melamine adhesive has the protective functions of scratch resistance, scoring resistance, wear resistance, water resistance and the like.
Description
Technical field
The present invention relates to melamine glue technical field, particularly a kind of for absorbing and decomposing melamine glue formula and the preparation technology thereof of formaldehyde in air.
Background technology
Formaldehyde is a kind of volatile organic compounds, colourless, have special odor, slightly overweight air, soluble in water.Formaldehyde has material impact to HUMAN HEALTH, has strong impulse effect to eyes, respiratory tract, human body mucous membrane and skin; The symptoms such as acute poisoning can cause shedding tears, runny nose, cough, cause various respiratory tract disease; Chronic inhalation of low concentration can cause unrelenting headache, unable, insomnia etc.; Chronic skin contact can cause dermatitis, produces detrimentally affect, cause lung and liver immunologic dysfunction to the respiratory system of human body, Digestive tract and central nervous system.Formaldehyde is so serious to harm, produces and the building material product of effective degradation of formaldehyde can cause the attention of building trade.
The method of existing elimination formaldehyde in air ability is following two classes:
(1) overlay as absorption layer upholstery building materials middle level or lower floors such as being sprayed on floor, furniture, decoration material by activated carbon or bamboo carbon powder and tealeaves or Chinese medicinal materials liquid or powder.This class methods shortcoming is: (a) is low to formaldehyde in indoor air elimination factor, and lasting effect is short.B () production technique length consuming time, is not suitable for streamline and produces fast.C () is simultaneously own opaque, if coating and building material surface, can hide the color of decoration material, texture or pattern.
(2) add, overlay negative ion bisque and building materials upper and lower surface.Negative ion powder anion releasing or negative oxygen ion, in air, go to eliminate formaldehyde.This method shortcoming is: formaldehyde elimination factor is low, and production difficulty is large;
(3) use spray except formaldehyde, this method shortcoming is: persistence is poor;
(4), in melamine glue manufacturing processed, repeatedly portion-wise addition urea, formaldehyde, trimeric cyanamide reduces sheet material formaldehyde content.This method only can reduce burst size of methanal, does not eliminate ability to discharging aerial formaldehyde.
Therefore be necessary to provide a kind of and can absorb and decompose the melamine glue of formaldehyde in air.
Summary of the invention
The object of the invention is to the defect for prior art and deficiency, a kind of efficient absorption is provided and decomposes melamine glue formula and the preparation technology thereof of formaldehyde in air.
For achieving the above object, the technical solution used in the present invention is:
Of the present inventionly a kind ofly absorb and decompose the melamine glue of formaldehyde in air, described melamine glue is made up of the component of following weight percent,
Further, described melamine glue is made up of the component of following weight percent,
Further, described amine is any one in amine, acid amides, imines, imide.
Further, described de-aldehyde agent is chitin.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: comprise the steps:
The water of a, predetermined weight, drops into formaldehyde, trimeric cyanamide, glycol ether and sodium hydroxide successively and stirs in water, makes the pH value of solution be 9;
B, stirring heating is carried out to step a solution, after making solution temperature rise to 90 DEG C, keep this temperature to stir 30min;
C, make step b solution temperature remain on 90 DEG C, in this solution, first drop into de-aldehyde agent, nano silicon stir 10min successively; Then in this solution, drop into amine and stir, making amine be evenly distributed in water; Finally naturally cool to less than 30 DEG C.
The present invention's beneficial effect is compared with prior art:
1, use the furniture of melamine glue in the present invention, floor, decorative sheet to have the ability eliminating formaldehyde in air, and aldehydes removal efficiency is high.
2, existing plant produced equipment availability can be applicable to;
3, this glue has scratch resistance, damage resistant, the defencive function such as wear-resisting, water-fast.
