Description
Technical field
The present invention relates to adhesive technical fields more particularly to a kind of timber adhesive and preparation method thereof.
Background technology
General plank, in order to which cost price and performance consider, need to often add various chemical substances to reach during bonding
The effects that application, hardening, gluing and anti-corrosion, and be most widely used be exactly formaldehyde system adhesive etc., contain formaldehyde
Deng the organic compound (volatile organic compounds, VOC) of performance property, so that after the completion of house decoration, these
Chemical substance influences indoor environmental quality in air with time and temperature change, in large quantities loss；However, people according to statistics
The time for about having more than 90% or more in life is that the architecture indoor in broad sense is aerial, therefore indoor environmental quality is good corrupt right
The health effect of human body is very big.
It is had confirmed from many research reports, contained formaldehyde and VOC are the main dirts of indoor environmental quality in plank
One of dye source, for example, being shown in the house of general finishing soon through investigation, the recall rate of formaldehyde and other pernicious gases is
100%, and be 40 times or more of maximum permissible concentration 0.08mg/m3 as defined in the World Health Organization (WHO), in finishing 5 days
Indoor concentration of formaldehyde is also 30 times of standard value or more afterwards, exceeded 3 times or more after 6 months, in fact, these plates
The acquisition time of the performance property such as contained formaldehyde organic compound can be usually up to 3~15 years in material, and in other words, it is to indoor ring
The pollution of border quality is very permanent.In addition, medical research report is further pointed out, the VOC such as aforementioned formaldehyde are that one kind exists
The form that can be evaporated under room temperature is present in air, its toxicity, irritation, carcinogenicity and special odor profiles can influence
Skin and mucous membrane generate acute lesion to human body, and usual concentration, which reaches 0.01~1.6ppm ranges, will start to stimulate eyes, dense
Degree reach 2~3ppm will allow eyes generate tingling sensation, 10~20ppm then can seriously shed tears, dangerous concentrations are up to after 30ppm just
Can life threatening can cause immunity of organism off-leveling in addition, some compounds have genotoxicity in VOC, and torture
The function of pivot nervous system and digestive system causes the injury of physical alterations；It follows that hiding the VOC arround indoors
The serious harm of health can not be ignored in fact.
Drawn in recent years by the various health crises and plank adhesive that are caused in response to indoor bad air quality
Health hazard of the VOC such as formaldehyde of the cause loss to indoor occupant, each main advanced country of the world also spininess to its plank and furniture
Dependent merchandise etc. establishes the specification and testing mechanism of formaldehyde and VOC loss control.So as to promote reduce room air pollution, really
Protect the interior space of healthiness.And in face of the surging environmental consciousness of people, and the tight demand to health, safety guarantee,
The adhesive without harmful substance is provided to produce the plank of system safety, has become the primary project of plank industry.
Therefore, in view of the above, needing reasonably to improve the prior art.
Invention content
For disadvantages described above, the present invention provide a kind of condensation is fast, intensity is high, stability is good, without formaldehyde, VOC and it is water-fast,
The timber adhesive and preparation method thereof for having flame retardant effect, to solve many deficiencies of the prior art.
To achieve the above object, the present invention uses following technical scheme：
Magnesia included in adhesive (MgO) and for condensing the di(2-ethylhexyl)phosphate of the magnesia (MgO) particulate
Hydrogen ammonium (NH4H2PO4), and uniformly reconcile into aqueous adhesive mixed liquor and using poly- using the solvent based on water (H2O)
The stickiness that sodium acrylate ([C3H3O2Na] n) adjusts mixed liquor with Strong flour as filler material enables it to reach in application
The effect of initial set is with convenient working, and application borax (Na2B4O7.10H2O) adjusts hardening time, reaches convenient for application
Purpose.
Being included at least according to a kind of timber adhesive of the present invention and preparation method thereof, in the coating has magnesia
(MgO) and it is used for and for condensing the ammonium dihydrogen phosphate (NH4H2PO4) of aforementioned oxidation magnesium (MgO) particulate, and utilizes water
(H2O) solvent based on uniformly reconciles into aqueous adhesive mixed liquor.
As a preferred technical solution of the present invention, magnesia (MgO) accounts for about 30%~40% weight in adhesive,
And ammonium dihydrogen phosphate then accounts for about 20%~30% weight.
Meanwhile the magnesia (MgO) calcines obtained weight for (1300~1700 DEG C) at high temperature by magnesite (MgCO3)
Burn MgO particles.The ammonium dihydrogen phosphate (NH4H2PO4) belongs to phosphoric acid salt, and main function is to provide hydrogen with Mg2+ ionic reactions
Ion and phosphate anion and magnesia (MgO) reaction generate magnesium phosphate cement.And in order to effectively control setting time,
Borax is added as retarder, the present invention utilizes the solvent based on water by the magnesia (MgO) and ammonium dihydrogen phosphate
(NH4H2PO4) it is uniformly mixed.
When making plank, there is different correspondence technique according to plank pattern difference, the present invention using adhesive of the present invention
The bonding solidification process of adhesive is that one between magnesia (MgO) and ammonium dihydrogen phosphate (NH4H2PO4) is anti-with acid-base neutralization
Reaction based on answering.
When ammonium dihydrogen phosphate (NH4H2PO4) dissolves rapidly and generate PO3-4, H-, NH+4 in water, solution is made to present
Faintly acid, the meeting of these ions and Mg2+ ionic reactions, the equation of reaction are as follows：
MgO+NH4H2PO4+5H2O=MgNH4PO4.6H2O
MgO+NH4H2PO4=MgNH4PO4.H2O
3MgO+2NH4H2PO4+H2O=Mg3 (PO4) 2.4H2O+2NH3
And it is as follows as retarder principle with borax：
It can be deposited in the surface of magnesia (MgO) particle after borax dissolving, form the aquation based on B4O72- and Mg2+
Product layer hinders contact of the particle surface with water to hamper the formation of gel so that crystallized to slow down hydrolytic process
Journey is slack-off.
A kind of timber adhesive of the present invention and preparation method thereof, preparation method is：
It is persistently stirred after Sodium Polyacrylate ([C3H3O2Na] n) is mixed with water until the consistency needed is presented, then again
Ammonium dihydrogen phosphate (NH4H2PO4) and borax (Na2B4O7.10H2O) are mixed into the above-mentioned consistence solution for having prepared completion, continued
Stirring makes it completely dissolved；Flour and magnesia (MgO) powder uniform stirring are mixed spare, when use is then mixed with above-mentioned pulvis
It closes and states mixed liquid, continue stirring until substantially uniformity mixing, you can complete the preparation of the adhesive.
A kind of timber adhesive of the present invention and preparation method thereof has the beneficial effect that：It can reach plank and be free of first
The effect of aldehyde, VOC；And the adhesive film formed after magnesia (MgO) solidification has good strength and water resistance and anti-flammability, is promoted
Safety in utilization..
Specific implementation mode
Magnesia included in adhesive (MgO) and for condensing the di(2-ethylhexyl)phosphate of the magnesia (MgO) particulate
Hydrogen ammonium (NH4H2PO4), and uniformly reconcile into aqueous adhesive mixed liquor and using poly- using the solvent based on water (H2O)
The stickiness that sodium acrylate ([C3H3O2Na] n) adjusts mixed liquor with Strong flour as filler material enables it to reach in application
The effect of initial set is with convenient working, and application borax (Na2B4O7.10H2O) adjusts hardening time, reaches convenient for application
Purpose.
