Description
Technical field
The present invention relates to building material field, more specifically, it relates to a kind of anti-fire door core board and preparation method thereof and
The application of the anti-fire door core board.
Background technology
The generation of 812 Binhai New Area in Tianjin explosion accidents, causes 165 people wrecked, 8 people's lost contacts, direct economic loss
68.66 hundred million yuan.This huge disaster while making people in bitter grief, also makes requirement of the relevant departments to fire proofing material more
Strictly.In numerous construction materials, fire resistant doorsets are one of the important fire prevention links in preventing fires link.
Currently, fire resistant doorsets mostly use greatly anti-fire door core board making, it is well known that the fire resistant doorsets made of anti-fire door core board
Skeletal support can be not only saved, the manufacturing process of fire resistant doorsets can also be simplified, improves production efficiency, reduces manufacturing cost.But
It is that for two kinds of current anti-fire door core boards, the first is the door panel using aluminium silicate wool as main material, due to its flue gas
National standard is not achieved in toxicity index, is prohibited use now；Another kind is using expanded perlite as main material
Door panel, due to the intensity difference of itself of perlite, after being bonded with steel plate or multi-layer board, the machining deformation of sheet metal, heat become
The factors such as shape and collision deformation, are easy to cause anti-fire door core board fragmentation, to influence the overall performance of fire resistant doorsets.Multi-layer board
After being bonded with core material plate made of perlite, in transport, installation process, by external force collision it is easy that core material plate is made to rupture, is being sent out
When calamity of lighting a fire, when the multi-layer board afterburnt, fire resistant doorsets, which just voluntarily fall apart, loses fireproofing function.
Also a kind of fire proofing material for being usually used in preparing fire-resistant door core --- magnesite material, magnesite foamed fireproofing Men Xin is new
The non-ignitable fireproof heat insulating product of a generation.Mainly natural chlorine oxygen magnesium inorganic environment-friendly material, through mechanical continuous productive process compacting it is compound and
At.It has it is non-ignitable not quick-fried, it is water-fast, oil resistant, resistant to chemical etching, the features such as nontoxic and high mechanical strength.But its there is also
Certain problem, containing a large amount of halide ions (mainly chlorion) in magnesite material ingredient, thus in the environment of hot humid
The moisture absorption easily occurs, returns halogen phenomenon, serious corrosion fire resistant doorsets steel matrix causes largely to waste.
In addition, the anti-fire door core board flexural strength for making a general survey of domestic production is low, fire protecting performance is poor, during high temperature fire
The problems such as structure is easily caved in.
Invention content
The object of the present invention is to provide a kind of anti-fire door core boards and the preparation method and application thereof, to solve existing fire-resistant door core
Plate there is technical issues that the moisture absorption, return halogen phenomenon and flexural strength low and high temperature fire during structure easily.
To achieve the above object, an aspect of of the present present invention provides a kind of anti-fire door core board, a kind of fire-resistant door core
Plate, including the group of following parts by weight are grouped as：
Advanced optimize for：A kind of anti-fire door core board, including the group of following parts by weight are grouped as：
Advanced optimize for：A kind of anti-fire door core board, including the group of following parts by weight are grouped as：
Advanced optimize for：The foaming agent is AB type composite foamable agents.
Advanced optimize for：The modifying agent is flyash or silicon ash or two kinds of combination.
As an aspect of of the present present invention, a kind of preparation method of anti-fire door core board is provided, the preparation method includes
Following steps：
One, each raw material is weighed according to components by weight percent；
Two, at normal temperatures, by MgCl2It is dissolved in a certain amount of water, the brine that Baume degrees is é -27 ° of B é of 25 ° of B is made；
Three, after the brine temperature obtained by step 2 is down to 40 DEG C or less, FeSO is added into above-mentioned brine4With
H3PO4, stir evenly to obtain clear solution；
Four, sodium tripolyphosphate, 801 glue, modifying agent and carbon fiber are added into the clear solution obtained by step 3, fully stirs
It mixes to obtain turbid solution；
Five, foaming agent is placed in another container, remaining water is added, fully foamed；
Six, the solution of gained in five is poured into and carries out first stage mixing treatment in four in the turbid solution of gained, obtained
Foam-like mixture；
Seven, the part of the MgO weighed is added in the foam-like mixture obtained by step 6 and carries out second stage
Mixing treatment obtains lean mixture；
Eight, the remainder of the MgO is added to the batch mixing that the phase III is carried out in the lean mixture obtained by step 7
Processing, obtains paste mixture；
Nine, the paste mixture obtained by step 8 molded curing is carried out to be molded to get anti-fire door core board.
Advanced optimize for：The molding condition of molded curing is：Normal temperature cure.
As another aspect of the present invention, anti-fire door core board of the present invention or fire prevention prepared by preparation method of the present invention are provided
Application of the door panel in fire-proof wooden door, fire resistance steel door, antitheft door, prized up-proof door, entering house door, art and craft door.
Compared with prior art, the beneficial effects of the present invention are：Flyash or silicon ash itself have the characteristics that the hydraulicity,
It adds it in the anti-fire door core board of the magnesium of oxygen containing chlorine, since itself generates hydraulicity hydrated product, and generates and quite count
The aluminium glue of amount effectively blocks the capillary channel of hardened paste during forming and hardening and forms protection in product surface
Layer, hence it is evident that improve the water repelling property of product, in addition can also form hydrophobic membrane in product surface, completely cut off product and outside moisture
Be in direct contact, slow down the infiltration of water vapour so that the surface halide accumulation resistance performance of product also improves a lot.For the first time will in the present invention
Carbon fiber is applied in the preparation of anti-fire door core board, and the axial strength and modulus of carbon fiber are high, and carbon fiber was formed in door panel
Network-like structure is spontaneously formed in journey, this network-like structure bundle bears other components and forms door panel, played by force to door panel
Gu effect so that anti-fire door core board High anti bending strength of the present invention.Carbon fiber also acts synergistically with other components, adsorption reaction
Magnesium, oxygen, phosphate anion in object, closer, the products therefrom intensity higher for making reaction product combine.By participating in reaction
Substance be inorganic matter, thermal conductivity is small so that the fire protecting performance and environmental-protecting performance of final product anti-fire door core board are excellent, and
It avoids the anti-fire door core board moisture absorption of the present invention, return the generation of the bad phenomenons such as halogen phenomenon.
