Description
Technical field
The present invention relates to a kind of fireproof door core material and its core plate production methods.
Background technique
With the rapid development of China's high-rise, miscellaneous steel, wooden, steel is wooden, composite material etc. is anti-
Vent constantly emerges in large numbers.Since fire resistant doorsets Market competition (counts, entirely according to Tianjin Fire Research Station and Sichuan Fire Research Station
State fire resistant doorsets goods producer has totally 1600 or so), some enterprises in order to make a profit and using price is low, insulating refractory performance is poor
Material substitution fire-resistant door core, lead to that fire resistant doorsets intensity is low, structural stability is poor, heat insulation is poor, occur when fire it is easily-deformable,
And release toxic and harmful gas, thus caused fire resistant doorsets quality problems are very serious.
Summary of the invention
The purpose of the present invention is to provide a kind of fireproof door core material and its core plate production method, solution is prevented fires in the prior art
Door core material intensity is low, structural stability is poor, heat insulation is poor, and skill that is easily-deformable when fire and discharging toxic and harmful gas occurs
Art problem.
In order to solve the above-mentioned technical problem the present invention, adopts the following technical scheme that：
A kind of fireproof door core material, the raw material of the fireproof door core material include expanded perlite, animal foaming agent, magnesium chloride,
Magnesia, anticracking fiber and water；Calculated by quality proportioning, expanded perlite account for 5-8 parts, animal foaming agent account for 8-20 parts, chlorine
Change magnesium account for 45-65 parts, magnesia account for 20-38 parts, anti-crack fiber account for 1-2 parts, water account for 4-7 parts.
Animality fire-resistant door core foaming agent is added certain using selected animal (ox, sheep) keratoprotein as main raw material(s)
The industrial chemicals such as the caustic soda (NaOH) of amount, hydrochloric acid, sodium chloride, heating dissolution, dilute filtration, high temperature dehydration and produce it is a kind of newly
Type foaming agent.Using foaming machine and fabrication process, production process carries out stringent qualitative control, and product is viscous in crineous
Property liquid, be a kind of nuisanceless, free of contamination water-soluble liquid, the low penetrating odor of impurity content is lighter, greater homogeneity, matter
It is good to measure consistency, there is good foaming characteristic and excellent foam stability.Since the foam surface generated with the foaming agent is strong
Degree is very high, and foam is extremely stable, and with the foaming door panel that it makes, each bubble is in mutually independent closed state, bubble
Be not connected between bubble, door panel permeability resistance very well, good heat-insulation effect, and stability is strong, and high temperature is unlikely to deform.Same
Under density, its leakproofness and heat insulating ability are preferable compared with the door panel made of vegetalitas foaming agent, and intensity is high, does not collapse.
Magnesia is white or pale yellow powder, odorless, tasteless, nontoxic, is typical alkaline earth oxide, chemical formula
MgO, white powder, fusing point are 2852 degree, and boiling point is 3600 degree, and relative density is 3.58 (25 DEG C), are dissolved in acid and ammonium salt indissoluble
Yu Shui, solution alkaline mix easy gel hardening with magnesium chloride solution.The physical characteristic of high-purity magnesium oxide is that have at high temperature
There are excellent alkali resistance and electrical insulating property.It is widely used as high-temperature heat-resistance material.
Magnesium chloride hexahydrate is easily reacted with magnesia and water mixing：
MgCl2.6H2O+3MgO+4H2O=3MgO.MgC12.10H2O, gel hardening improve door core strength and stability.
It is further improved, the raw material of fireproof door core material further includes grid cloth, accounts for 0.5-1 parts.When making anti-fire door core board
Grid cloth is laid on bottom surface, prevents core plate surface from cracking.
It is further improved, the raw material of fireproof door core material further includes ammonium polyphosphate flame retardant, accounts for 8-13 parts, ammonium polyphosphate is gathered
It is right to be greater than 100.Ammonium polyphosphate is that long chain is phosphorous, inorganic polymer of nitrogen, and general molecular formula is：(NH4P03)n.It has
Chemical stability is good, hygroscopicity is small, dispersibility is excellent, specific gravity is small, low toxin.The degree of polymerization of ammonium polyphosphate is to determine it
As the key of flame retardant products quality, the degree of polymerization is higher, and fire retardant effect is better.By adding ammonium polyphosphate flame retardant,
Further increase the flame retardant property of fire resistant doorsets door core.It buys in Shandong Zibo Sai Da flame-retarding new material Co., Ltd.
It is further improved, the anti-crack fiber is polypropylene anti-crack fiber, resistance to strong acid, resistance to highly basic, weak thermal conductivity, with pole
Its stable chemical property.
The production method of anti-fire door core board, includes the following steps：
Step 1: taking suitable magnesia and water, magnesium chloride solution is configured, and cracking resistance fibre is added in magnesium chloride solution
Dimension；
Step 2: expanded perlite, animal foaming agent, magnesia and ammonium polyphosphate are weighed, by it according to formula rate
It is placed in blender machine, and the solution in step 1 is added, stir evenly；
Step 3: cleaning mold, is laid at least one layer of grid cloth in the bottom of mold, then will stir evenly in step 2
Raw material be filled into mold；
Step 4: being press-formed to the filler material in step 2, pressure 10-30Mpa, pressing time is 10-15 points
Clock, filler material temperature is 15-35 DEG C when pressurization；Using hot pressing, core plate compactness is good, and structure is uniform, and intensity is high.
Step 5: the shape plate preliminarily formed is removed from the molds, then in 20 ± 1 DEG C of relative humidity 55 ± 2% of temperature
Maintenance 10 days, that is, be made anti-fire door core board in the workshop of rh.
It is further improved, is stirred using UJZ400 horizontal shaft blender, mold is aluminium sheet casting die, using NY-1 roller
Pressing machine is press-formed filler material.
Be further improved, the expanded perlite account for 6 parts, animal foaming agent account for 10 parts, magnesium chloride account for 60 parts, magnesia
Account for 24 parts, anti-crack fiber account for 1.2 parts, ammonium polyphosphate account for 10 parts, water account for 5 parts, grid cloth account for 0.7 part.
According to the anti-fire door core board that the above method makes, internal structure is honeycomb, anti-fire door core board fire resistance temperature
More than or equal to 1100 DEG C technologies.According to GB8624-2012《Classification on burning behaviour for building materials》, persistently risen in high temperature furnace
Temperature, flame bombard specimen surface, T≤30 DEG C sample surfaces temperature rise △, and mass loss △ m≤50%, tf=0 (without lasting combustion
Burn), sample reaches A1 index.
Internal structure is that cellular anti-fire door core board flexural strength is more than or equal to 0.95MPa, and deformation resistance refers to fire prevention
Door resists the ability that the temperature difference generates stress zone to deform in unidirectional thermal histories, since fire resistant doorsets are unidirectionally heated, along plate thickness
The temperature difference that direction generates is huge, and side towards the fire temperature is up to 1000 DEG C or so, and unexposed surface temperature is up to 180'C, therefore side towards the fire
Swelling stress it is very big, cause the deformation of plate larger.
