Description
Technical field
The invention belongs to fire proofing material and its preparing technical field, and in particular to a kind of power equipment environment-friendly fireproof material
Material and preparation method thereof.
Background technology
With developing rapidly for modern science and technology and power industry, power equipment has become our routine works and life is worked as
In important component part, for we providing such as commercial power, civilian electric power, telecommunications, data transfer, internet, business
The multi-faceted electrical power services such as industry, finance, science and technology, medical treatment.Our dependences to electric power also become increasingly strong.With past feelings
Condition is compared, and power equipment high-precision itself, function are more and more complete, and cost also becomes more and more expensive, so electric
The fire of very little of power equipment all will result in very serious consequence.Wherein not only include the loss of equipment itself, and by
It is even more inestimable that the electrical power services of this initiation interrupt brought loss.Therefore, the safety of power equipment, particularly to fire
Strick precaution, have changed into guarantee power equipment safety, it is ensured that the matter of utmost importance of the normal operation of electrical power services.Coating fire proofing material is
A kind of economic, safe measure, along with the fire-hazard protective system of modernization, the safety that can solve power equipment well is asked
Topic.
Fire proofing material can be divided into two class of expansion fire-proof material and non-expansion type fire proofing material by its fire retardant mechanism.Non-
Intumescent coating mainly passes through the flame retardancy and noninflammability of coating itself, while can discharge fire extinguishing under flame or high temperature
Gas, and form non-flame properties inorganic " glaze film " layer and completely cut off 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, forms the original thickness of ratio several ten times larger or even hundreds of times
The spongy carbonaceous layer of low flammability, to completely cut off heating of the extraneous flame to base material.Produce during film melting expansion simultaneously
A large amount of non-flammable gases, dilute the imflammable gas that ground thermal decomposition is produced, can effectively prevent spreading for flame, be really have
The fire proofing material of effect.Expandable flame retardant polymer is the novel Flame Retardant Technology grown up on the basis of anti-flaming dope.It is by
Expansion type flame retardant containing carbon source, acid source and source of the gas and polymer blending processing, form fire proofing.Expansion flame-retardant material fires
During burning, acid source releases inorganic acid, the polyhydric alcohol that carbon source contains, and then dehydration carbonization, sticky carbonizing production is released in source of the gas
Expand in the presence of the small molecule volatile matter of the inert gas, the water vapour that reaction is produced and depolymerization generation put, formed
The layer of charcoal of microcellular structure.The foamed char has oxygen barrier, effect that is heat-insulated, dripping and make flame self-extinguishment without molten drop.
At present, fire proofing material on the market can effectively protect the damage and deformation of structures based on intumescent, once
There occurs that fire, 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 avoid causing more casualties and property loss.Patent CN201210217965.7 is public
Bromine carbon alkyd resin cable fire-refractory coating and preparation method thereof is opened, the group of the fireproof coating is divided into：Bromine carbon alkyd resin, poly- phosphorus
Sour ammonium, melamine, pentaerythrite, antimony oxide, Firebrake ZB, 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 combination property is projected.But

Crystal, is added in fire proofing material and can improve the fire resistance of base material, strengthens melt stability, at the same improve layer of charcoal intensity and
Stability, charring layer inner structural strength increase, and hole wall is thickened.Cooperateed with by above-mentioned each material, protect base material, be allowed to prevent spoke
Heat and the directly contact with flame is penetrated, the fuel gas that produces during external firing is effectively isolated and heat is internally propagated,
So as to reach fire-retardant purpose.
Fire retardant of the present invention adopts tetraphenyl diphenol A diphosphonate, melamine phosphate and dipentaerythritol compounding use,
Test shows that the solubility under the fire retardant normal temperature in most common solvents is relatively low, with good thermally-stabilised
Performance, defines ideal cooperative flame retardant effect with film forming matter and its additive etc., can be formed in substrate surface suitable
When the stable layer of charcoal of thickness, without melting drip phenomenon during burning, the fire resistance of base material is significantly improved, while brushing in base material table
The mechanical property of base material can be improved in face.
Fire proofing material of the present invention is applied to power equipment fire prevention, with excellent cracking resistance energy, water resistance and weather-proof
Property, good expansion character, while HRR of the base material under fired state can be significantly reduced, reduces mass loss,
And smoke-producing amount is little, environment protecting is good.

Observe at 0.5m, whether range estimation surface has crackle, flawless is then qualified.
2nd, water resistance：By in 2/3 immersion running water of the cold bundle steel plate of coating fire proofing material, test specimen is taken out after 36h and is seen
Examine, if without aliquation, foaming, obscission, for qualified.
3rd, weatherability：The cold bundle steel plate of coating fire proofing material is placed in 18h in the air of (23 ± 2) DEG C, then by test specimen
It is put in the cryogenic box of (- 20 ± 2) DEG C, from the temperature inside the box reaches -18 DEG C, test specimen is taken out from cryogenic box by freezing 3h again,
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
Fall, foaming phenomena, then for qualified.
4th, expansion multiplying power n：The coating layer thickness of the cold bundle steel plate of each coating fire proofing material is recorded, in the center of test specimen and back of the body fire
Face places two thermocouples, test sample plate internal temperature and the fiery temperature of the back of the body respectively, and model is placed in trial furnace, gas flame
Size adjustment extremely can coat model completely, start to test to test when flame temperature reaches 1000 DEG C to terminate, wherein furnace flame
Temperature ramp is heated up by standard heating curve shown in 1.1.2 sections in GB/T9978.1-2008.Test is recorded after terminating
Internal temperature and the numerical value of the fiery temperature of the back of the body, are observed layer of charcoal and are combined situation with ground, and take 3 respectively in model bottom surface and two sides
Individual point measures layer of charcoal expanded thickness, is calculated as follows expansion multiplying power n, and the sample layer of charcoal expansion multiplying power is 9 point expansion multiplying powers
Average.
N=(d-d0)/d0
In formula, d is layer of charcoal expanded thickness after test, d0For testing Front-coating mirror brushing thickness.
