Description
Technical field
The invention belongs to fire proofing material and its preparation technical fields, and in particular to a kind of power equipment environment-friendly fireproof material
Material and preparation method thereof.
Background technique
With the rapid development of modern science and technology and power industry, power equipment has become our routine works and life is worked as
In important component, for we provide such as commercial power, civilian electric power, telecommunications, data transmission, internet, quotient
The multi-faceted electrical power services such as industry, finance, science and technology, medical treatment.We also become increasingly strong to the dependence of electric power.With past feelings
Condition is compared, and power equipment high-precision itself, function is more and more complete, and cost also becomes more and more expensive, so electric
The fire of very little of power equipment will all cause consequence very serious.It wherein not only include the loss of equipment itself, and by
It is even more inestimable that this electrical power services caused interrupts brought loss.Therefore, the safety of power equipment, especially to fire
Prevention, have changed into guarantee power equipment safety, it is ensured that electrical power services operate normally matter of utmost importance.Coating fire proofing material is
A kind of economic, safety measure, along with the fire-hazard protective system of modernization, the safety that can well solve power equipment is asked
Topic.
Fire proofing material presses its fire retardant mechanism, can be divided into two class of expansion fire-proof material and non-expansion type fire proofing material.It is non-
Intumescent coating is mainly the flame retardancy and noninflammability for passing through coating itself, while fire extinguishing can be released under flame or high temperature
Gas, and form non-flame properties inorganic " glaze film " layer isolation air, to prevent or retardation coated article ignition.Expansion fire-proof
It is expanded charred that material is that its coating occurs under flame or high temperature, formed one it is more several ten times larger than original film thickness or even hundreds of times
The spongy carbonaceous layer of low flammability, to completely cut off heating of the extraneous flame to substrate.It is generated during film melting expansion simultaneously
A large amount of non-flammable gases dilute the imflammable gas that ground thermal decomposition generates, can effectively prevent the sprawling of flame, be really to have
The fire proofing material of effect.Expandable flame retardant polymer is the novel Flame Retardant Technology to grow up on the basis of anti-flaming dope.It is by
Processing is blended with polymer for expansion type flame retardant containing carbon source, acid source and gas source, forms fire proofing.Expansion flame-retardant material combustion
Acid source releases inorganic acid, the polyhydric alcohol for containing carbon source when burning, and then dehydration carbonization, sticky carbonizing production are released in gas source
It expands, is formed under the action of the small molecule volatile matter of inert gas, the water vapour that reaction generates and the polymer degradation generation put
The layer of charcoal of microcellular structure.The foamed char have the function of it is oxygen barrier, heat-insulated, dripped without molten drop and make flame self-extinguishment.
Currently, fire proofing material on the market based on intumescent, can be effectively protected the damage and deformation of structures, once
Fire has occurred, the protective effect of fire proofing material can increase personnel and escape time and rescue time, greatly reduce maintenance cost,
Shorten engineering repair time, and avoids more casualties and property loss.Patent CN201210217965.7 is public
Bromine carbon alkyd resin cable fire-refractory coating and preparation method thereof, the component of the fireproof coating are opened are as follows: bromine carbon alkyd resin, poly- phosphorus
Sour ammonium, melamine, pentaerythrite, antimony oxide, zinc borate, bentonite, titanium dioxide, chlorinated paraffin, molybdenum sesquioxide, two
Methyl-silicone oil, drier, solvent.The invention fireproof coating is used for cable fire-proof, and properties are balanced, and comprehensive performance is prominent.But
Smoke-producing amount is more when being fire proofing material burning, and cracking resistance can need to be improved.Patent CN201610263081 discloses one

Outside, the present invention also added suitable alumina silicate fibre, on the one hand cooperate with expanded graphite, and the intensity of burning layer of charcoal can be improved,
Layer of charcoal crackle is reduced to generate；Another aspect alumina silicate fibre property is stablized, and thermal conductivity is low, can prevent flame, oxygen, caloic etc.
Transmitting, the thermal conductivity of material can be reduced, play the role of thermal insulation protection.Molecular sieve is a kind of alumino-silicate with skeleton structure
Crystal, addition can be improved the flame retardant property of substrate in fire proofing material, enhance melt stability, at the same improve layer of charcoal intensity and
Stability, charring layer inner structural strength increase, hole wall thickening.It is cooperateed with by above-mentioned each material, protects substrate, be allowed to prevent spoke
It penetrates heat and is contacted with the direct of flame, be effectively isolated the fuel gas generated when external firing and heat is internally propagated,
It is fire-retardant to achieve the purpose that.
Fire retardant of the present invention is used in compounding using tetraphenyl diphenol A diphosphonate, melamine phosphate and dipentaerythritol,
Experiments have shown that the solubility under the fire retardant room temperature in most common solvents is relatively low, there is good thermostabilization
Performance forms ideal cooperative flame retardant effect with film forming matter and its additive etc., can be formed in substrate surface suitable
When the stabilization layer of charcoal of thickness, burning without melting drip phenomenon, the flame retardant property of substrate is significantly improved, while being brushed in substrate table
Face can be improved the mechanical property of substrate.
Fire proofing material of the present invention is prevented fires applied to power equipment, has excellent cracking resistance energy, water resistance and weather-proof
Property, good expansion character, while heat release rate of the substrate under combustion state can be significantly reduced, mass loss is reduced,
And smoke-producing amount is small, and environment protecting is good.

It examines, if without aliquation, foaming, obscission, for qualification.
3, weatherability: the cold bundle steel plate for coating fire proofing material is placed in 18h in the air of (23 ± 2) DEG C, then by test specimen
It is put into the cryogenic box of (- 20 ± 2) DEG C, 3h is freezed from the temperature inside the box reaches -18 DEG C and again takes out test specimen from cryogenic box,
It is immediately placed in the insulating box of (50 ± 2) DEG C, constant temperature 3h, takes out test specimen and repeat aforesaid operations totally 20 circulations, if without cracking, stripping
It falls, foaming phenomena, is then qualification.
4, expansion multiplying power n: recording the coating layer thickness of the cold bundle steel plate of each coating fire proofing material, center and back fire in test specimen
Two thermocouples, test sample plate internal temperature and the fiery temperature of back are placed in face respectively, and template are placed in trial furnace, gas flame
Size is adjusted to can coat template completely, start to test to test when flame temperature reaches 1000 DEG C to terminate, wherein furnace flame
Temperature ramp saves shown standard heating curve by 1.1.2 in GB/T9978.1-2008 and heats up.It is recorded after test
Internal temperature and the numerical value for carrying on the back fiery temperature, observe layer of charcoal situation in conjunction with ground, and take 3 respectively in template bottom surface and two sides
A point measures layer of charcoal expanded thickness, and expansion multiplying power n is calculated as follows, which is 9 expansion multiplying powers
Average.
N=(d-d0)/d0
In formula, d is layer of charcoal expanded thickness after test, d0To test Front-coating mirror brushing thickness.
