In the preparation technology of aforementioned dual-component polyurethane super-thin steel structure fire-proof paint, the coat-thickness of the frie retardant coating that this preparation technology prepares is 1-3mm, and fire endurance reaches 150-160min.
The insulating mechanism of frie retardant coating of the present invention is:
Frie retardant coating of the present invention is primarily of material compositions such as binder resin, char forming catalyst, char-forming agent, whipping agent and smoke suppressants, and when coating is heated, carbonifying catalyst decomposes discharges flame retardant resistance gas NH3 and H
2while O, produce acid catalyst, require that the mineral acid boiling point discharged is high, and oxidisability is not too strong, char-forming agent is the carbon source of expanded porous layer of charcoal, is the polyfunctional group containing carbon rich, can separately or be heated into charcoal under catalyst action, char-forming agent dewaters through multistep under acid catalysis, resolve into charcoal, fluoropolymer resin melted by heating in base-material, and it is expanded foamed under the effect of whipping agent, form fine-celled foam layer of charcoal further simultaneously, this layer of carbonaceous layer effectively can break off the direct heating of flame to ground, the contact of isolated ground and air, and effectively stop heat to the transmission of ground, simultaneously, softening of coating, melting, the physical changes such as expansion and polymkeric substance, filler, the decomposition of auxiliary agent, the chemical actions such as evaporation and charing will absorb amount of heat, reduce temperature of combustion and flame propagation velocity, the non-flammable gases decomposited can water down the concentration of oxygen, the hydrogen halide of high temperature release, the free radical that burning produces can be caught, combustion reactions is stopped, play fire extinguishing.
The invention has the beneficial effects as follows:
In material, mainly add fire retardant to improve the flame retardant properties of material at present, general halogenated flame retardant good flame retardation effect, but the amount of being fuming is large during its burning, produce corrodibility and toxic gas, and in the present invention, select bromide fire retardant significantly can reduce the discharge of toxic gas when fire-retardant superpolymer burns, be conducive to environment;
The more frie retardant coating of domestic use is still and reaches fire-retardant object by adding a large amount of small molecules fire retardant, due to the interpolation of a large amount of small molecules fire retardant, reduces the water resistance of coating, and can not ensure the long-term highly effective flame-retardant of coating; And bromine carbon urethane resin matrix material of the present invention is a kind of brominated flame retarded polymeric material of synthesis, its matrix resin being used as frie retardant coating solves the inflammable problem of frie retardant coating matrix resin, bromine carbon urethane resin matrix material also solves in frie retardant coating as organic polymer material and adds because of a large amount of the problem that fire retardant causes the defect that frie retardant coating is water-fast, not good, the fire-retardant timeliness of weather resistance is short simultaneously, reaches long-term efficient fire-retardant object.
Bromine carbon urethane resin in the present invention has higher intensity, elasticity and elongation at break, and aramid fiber has the excellent properties such as specific tenacity is high, specific modulus is high, aramid fiber is joined in bromine carbon urethane resin to make it to combine and obtain bromine carbon urethane resin matrix material, high strength, high-modulus, high abrasion, tear-resistant material can be obtained, enhance the performance of frie retardant coating, extend the work-ing life of steel construction, ensure that security.
Subsection charging method is adopted when preparing bromine carbon urethane resin matrix material in the present invention, the base polyurethane prepolymer for use as of molecular weight can be obtained, due to the obvious oligoethylene glycol-400 of OH and NCO reactive behavior in tetrabromo-bisphenol, the reactive behavior of TriMethylolPropane(TMP) and NCO, react if all raw materials are once added, then PEG-4000, TriMethylolPropane(TMP) and 2, after in 4-tolylene diisocyanate, contraposition NCO reacts, tetrabromo-bisphenol reacts with ortho position or the remaining NCO of contraposition again, to such an extent as to product structure irregularity, molecular weight distribution is uneven, if when there is no the effect of hydrogen bond yet, even if when low temperature or high stretch ratio, also not easily crystallization, cause the sharply reduction of intensity level on stress-strain curve, be unfavorable for improving its ultimate property, and extend the reaction times, therefore first by tetrabromo-bisphenol and excessive 2, 4-tolylene diisocyanate fully reacts, add PEG-4000 again, TriMethylolPropane(TMP) continues reaction and stablizes to nco value, this subsection charging technique is simple, product structure is regular, substantially reduce the time of reaction.
Primary ammonium phosphate, Secondary ammonium phosphate, ammonium polyphosphate, melamine phosphate etc. all can be used as char forming catalyst, and wherein melamine phosphate foaming is best, but cost is higher; Primary ammonium phosphate, Secondary ammonium phosphate water tolerance are poor, ammonium polyphosphate cheap, toxicity is low and wide material sources, consider from price, performance, raw material sources and the requirement to water resistance, ammonium polyphosphate is good.
Aluminium hydroxide is have employed in the present invention, aluminium hydroxide can issue raw decomposition reaction at 200 DEG C, generate aluminum oxide and water, and absorbing amount of heat, the water vapour of generation effectively can dilute inflammable gas and the oxygen of steel structure surface, makes it heat up slowly, slowed down the speed of burning, the pellumina simultaneously generated covers charring layer surface, and further starvation, plays an important role in frie retardant coating.
Fire-retardant material of the present invention is two component mixing system, adopts the binder resin of bromo element, reaches long-term fire retardation efficiently, also reduces the consumption of inorganic molecules fire retardant simultaneously, further increase the mechanical property of coating.
