Description
Technical field
The invention belongs to building fire protection material fields, and in particular to a kind of fire proofing material of high-strength fireproof.
Background technique
In modern industry and civil buildings using ceiling do decoration it is more and more, on the ceiling aperture installation it is low
Pressing energy-saving lamp is even more a kind of inexorable trend；But this will bring biggish fire hazard: on the one hand, low-voltage energy-saving lamp transformer
It works long hours, if heat dissipation is bad, energy accumulation, temperature rises, Yi Yinqi appliance fire；On the other hand, ceiling
Fire endurance is greater than 1 hour, and the fire resistance of low-voltage energy-saving lamp does not reach requirement.Once fire occurs, flare will pass through
The mounting hole of low-voltage energy-saving lamp channels to the upper space of ceiling, to form stack effect, the intensity of a fire increases, and causes bigger break
It is bad.Flameproof enclosure covers the transformer and mounting hole of low-voltage energy-saving lamp, just can solve this problem.
Applied fireproofing is used in flameproof enclosure, patent of invention CN201410661311.2 discloses a kind of aluminum phosphate-expansion stone
Ink-alumina-silicate ceramic fibre heat-insulating and fire-proof composite material preparation method, with aluminium hydroxide, phosphoric acid, n,N-dimethylacetamide,
Expanded graphite, Tri-isopropylphenyl phosphate and alumina-silicate ceramic fibre are primary raw material, prepare aluminum phosphate lotion first, then match
Aluminum phosphate-expanded graphite-alumina-silicate ceramic fibre mixed serum processed, is later heat-treated mixed serum through graded series, is made
Aluminum phosphate-expanded graphite-alumina-silicate ceramic fibre heat-insulating and fire-proof composite material.The patent is a kind of thermal insulation material, and is not suitable for
It is generated in as fire proofing material, having organic exhaust gas in process of production, is absorbed with active carbon, chemical waste can be generated, it is dirty
Contaminate environment.
Summary of the invention
In order to solve the above-mentioned technical problems, the present invention provides a kind of flameproof enclosures of high-strength fireproof.Can effectively prevent or
Slow down the oxidation rate of expanded graphite, improves fire endurance.
In order to achieve the object of the present invention, the technical solution adopted by the present invention is that:
A kind of fire proofing material of high-strength fireproof, according to the mass fraction, including following component:
100 parts of high temperature fiber
10~100 parts of expanded graphite
0~20 part of filling powder
2~10 parts of binder
0.1~10 part of oxygen interleaving agent
0~2 part of hydrophober.
The rapid spatial expansion of expanded graphite under high temperature forms low-density, low thermal conductivity and air-locked enclosed material
Layer, completely cuts off the propagation of flare and flue gas, at the same can also trap heat transmitting, reach and fire behavior be confined to original space, and
It cannot be to the purpose of other spatials.
Including following component preferably, according to the mass fraction:
100 parts of high temperature fiber
10~100 parts of expanded graphite
2~20 parts of filling powder
2~10 parts of binder
0.1~10 part of oxygen interleaving agent
0.1~2 part of hydrophober.
Oxygen interleaving agent of the present invention is attached to the surface of expanded graphite.
Present invention discover that graphite can start to aoxidize in 300 DEG C or more of temperature, 700 DEG C will vigorous oxidation, will cause anti-
The decline of fiery cover fire endurance.Therefore oxygen interleaving agent is added in fire proofing material, barriers for oxygen melts shape at high temperature
At liquid and it is attached to the surface of graphite material, has completely cut off the contact of the oxygen and graphite material in air, has prevented from aoxidizing.
High temperature fiber of the present invention is alumina fibre, Zirconium oxide fibre, alumina silicate fibre or silicon oxide fibre.
Oxygen interleaving agent of the present invention is selected from least one of zinc borate, ammonium phosphate, trbasic zinc phosphate and aluminum phosphate, all
It can play the role of cladding expanded graphite, completely cut off air.
Preferably, the mass ratio of the oxygen interleaving agent and graphite is 6-20:100, and the covered effect under the ratio is most
It is good.
Preferably, the oxygen interleaving agent is zinc borate and aluminum phosphate, and mass ratio is 3-8:10.Zinc borate and phosphorus
Sour aluminium can form high temperature resistant network molecular structure at high temperature, and graphite is tightly coated, prevents oxidation effectiveness best.
Hydrophober of the present invention in warm octadecylsilane, butylsilane and vinyl silanes at least one
Kind.
The present invention also provides the preparation methods of the fire proofing material of high-strength fireproof, comprising the following steps:
A, expanded graphite pre-processes: expanded graphite and oxygen interleaving agent being added in high-speed mixer by formula rate and stirred, is added
The water for entering total amount 2-3%, is sufficiently mixed, spare；
B, pretreated expanded graphite, high temperature fiber, filling powder and bonding agent are uniformly mixed by formula rate；
C, the compression moulding in a mold of uniformly mixed above-mentioned material, hydrophober is sprayed, is toasted, is formed to get specific shape
Product.
Preferably, the step A toasts the material after being sufficiently mixed 60-120 minutes at 110-130 DEG C.
The beneficial effects of the present invention are:
1, the expanded graphite in fire proofing material, high temperature fiber and hydrophober collective effect play fire-retardant effect.Present invention discover that
Graphite can start to aoxidize in 300 DEG C or more of temperature, 700 DEG C will vigorous oxidation, will cause under fire proofing material fire endurance
Drop.Therefore oxygen interleaving agent is added in fire proofing material, barriers for oxygen melts to form liquid and adhere at high temperature
On the surface of graphite material, the contact of the oxygen and graphite material in air is completely cut off, has avoided the oxidation of graphite material and make
At fire prevention failure, improve the fire endurance of fire proofing material, be increased to 240min from 60min.
2, present invention selection zinc borate and the optimal oxygen interleaving agent combination of aluminum phosphate.Zinc borate and aluminum phosphate are at high temperature
High temperature resistant network molecular structure can be formed, graphite is tightly coated, effectively prevent aoxidizing.
3, preparation method of the invention first uses oxygen interleaving agent to pre-process expanded graphite, is added total amount 2-3%'s
Water is the surface in order to enable oxygen interleaving agent and water be attached to expanded graphite together in mixing；Toast again be in order to oxygen every
Expanded graphite can be preferably coated at high temperature from material.
