Description
Technical field
The present invention relates to fireproof coating technical field, more particularly to a kind of aging-resistant flame-proof expansible graphite water super-thin
Fire-resistant coating for steel structure and preparation method thereof.
Background technology
Solvent-borne type super-thin steel structure fireproof coating contains substantial amounts of volatile organic matter（VOC）, which is applied and is increasingly subject to
Limit, or even disabled by developed country.Water super-thin steel structure fire-proof paint is reduced using waterborne polymeric as film forming matter
The discharge capacity of VOC, reduces the coating harm to human body and pollution to environment in the links such as production, construction, application, symbol
Energy-saving and emission-reduction, the development trend of environmental protection are closed, is the emphasis of fireproof coating research.This paper is directed to water super-thin steel structure
The fire protecting performance of fireproof coating is poor, expansion multiplying power is low, low expanding layer structural strength, poor water resistance the problems such as deeply ground
Study carefully, and to film forming matter（The tertiary polymer of vinegar）Thermal decomposition process and charcoal forming machine reason, APP to the thermal decomposition of vinegar tertiary polymer
The impact of process is discussed；Nano zirconium dioxide and aqueouss phosphorous polymer are have studied exploratoryly in fireproof coating
Using.Main research work is as follows：（1）Film forming be have studied from the angle of thermal decomposition characteristic, Dynamic Rheological Properties and compound viscosity
Impact of the material to fireproof coating expansible fireproof performance.Result of study shows：Pure third and the storage modulu of cinepazid polymer melt
（G ＇）More than loss moduluses（G ＂）, based on elasticity flowing, it is combined viscosity high（>1000Pa·s）；The G ＂ of the tertiary polymer melt of vinegar
More than G ＇, based on VISCOUS FLOW, viscosity is combined low（33Pa·s）.With heat stability is good, char forming ability strong, compound viscosity
The polymer of low, viscous fluid characteristics is suitable as the film forming matter of fireproof coating, is conducive to expansion and the fire protecting performance of coating
Raising.（2）With the tertiary polymer of vinegar（VAc-VeoVa）As film forming matter, APP/tetramethylolmethane/tripolycyanamide/can be swollen
Swollen graphite（APP/PER/MEL/EG）As Intumescent Retardant System（IFR）, have studied IFR and its with VAc-VeoVa with comparing
The impact of Properties of Fire-Proofing Coatings.Orthogonal experiment analysis result directly perceived shows that impact of each component to Properties of Fire-Proofing Coatings is suitable in IFR
Sequence is followed successively by：APP ＞ EG ＞ PER ＞ MEL, optimum proportioning is APP:PER:MEL:EG=22:8:8:4.5.When VAc-VeoVa is used
Measure for 30%, IFR consumptions be 40% when, the fire protecting performance of fire resistant coating is optimal（After burning 30min, steel plate back of the body temperature is 262 DEG C）.（3）
Have studied impact of the factors such as composition, granular size and the form of inorganic filler to fireproof coating.TG, capillary rheology test,
The results of study such as fire protecting performance test show：With TiO2/SAp/HNTs（8/1/1）As during inorganic filler, fireproof coating it is anti-
Fiery excellent performance（3327s）, expansion multiplying power is higher（28.14）, expansion Rotating fields are good, intensity is high.Inorganic filler is by being constrained to
Membrane polymer strand lax and rotate, and APP is reduced on the catalytic dehydration efficiency of PER and VAc-VeoVa to affect to prevent
The expansion multiplying power and fire protecting performance of fiery coating.Simultaneously when viscosity is higher, inorganic filler is difficult to move to expanding layer surface aggregation
Inorganic thermal insulation layer is formed, causes the fire protecting performance of fireproof coating to decline.By formulation optimization, the performance of aqueous fire-proof coating is made by oneself
Famous foreign brand is exceeded.（4）Have studied nano zirconium dioxide（nano-ZrO2）Effect in fireproof coating.Research knot

There is in VAc-VeoVa emulsions good dispersibility.In the halogen-free flameproof coating without EG, nano-ZrO is added2After expand
Layer no longer has continuous fine and close structure, and structural strength is reduced, and fire protecting performance is with nano-ZrO2Under consumption ground increases on the contrary
Drop.There is halogen fireproof coating containing EG, EG is interspersed in expanding layer, play a part of structural support；ZrO2In expanding layer
In play a part of heat-insulated and prevent thermal oxide from decomposing, the fire prevention time reaches 3837s.XRD results are generated in showing expanding layer
Titanium pyrophosphate（TiP2O7）, zirconium pyrophosphate（ZrP2O7）With zirconium pyrophosphate magnesium-titanium solid solution（Ti0.8Zr0.2P2O7）.（5）Have studied
Impact of the thermal decomposition process and APP of Vac-VeoVa to VAc-VeoVa thermal decomposition processes.Result of study shows：In air atmosphere
The thermal oxide catabolic process of middle VAc-VeoVa is divided into three phases：（1）Removing acetic acid and tertiary carbon acid groups, generate unsaturated carbon
Chain；（2）The oxidative dehydrogenation of unsaturated carbon chains, cyclisation, aromatisation, generate hexagonal crystal system carbon；（3）The thermal oxide of hexagonal crystal system carbon.
In nitrogen atmosphere, VAc-VeoVa thermal decomposition processes are divided into two stages：（1）Removing acetic acid and tertiary carbon acid groups, generate insatiable hunger
And carbochain；（2）The chain rupture or cyclisation of unsaturated carbon chains, aromatisation, generate hexagonal crystal system carbon.Density functional theory（DFT）Meter
Calculate relation of the removing for competition fracture that result shows versatic acid and acetic acid group in VAc-VeoVa molecules.TG and FTIR results
Show, APP reduces the heat decomposition temperature of VAc-VeoVa, accelerate the removing speed of VAc-VeoVa side-chain radicals.Additionally,
The pendant hydroxyl group reaction that the polyphosphoric acid that APP is thermally decomposed to generate is generated after removing ketenes with VAc-VeoVa molecules generates P-O-C
Key.The product generated after ethylenic unsaturation hydrocarbon aromatizing is connected to become cross-linked network shape structure by P-O-C keys, has charcoal residue
More preferable heat stability.（6）The phosphorous cinepazid polymer P of aqueouss is synthesized（MMA/St/BA/MAA/PAM100）, and in this, as
Film forming matter, have studied its application in fireproof coating.Result of study shows, vinyl alkoxy phosphate ester（PAM100）Carry
The high heat stability of polymer, belongs to the condensed phase mechanism of action.Fire protecting performance test result shows, using StA-P1.5 as into
The fire protecting performance of fireproof coating prepared by membrane substance is optimal.Flymn-Wall-Ozawa（FWO）Method and Kissinger-
Akahira-Sunose（KAS）Method result of calculation shows that PAM100 considerably increases the thermal degradation activation energy of polymer, but
Activation energy increasing with PAM100 consumptions and reducing.The mechanism function of polymer thermal decomposition is respectively g（α）=-ln（1-α）, f（α）
=1- α, order of reaction n=1, rhermal decomposition rate expression formula are ddtAexpE/RT1.
《The preparation of water super-thin steel structure fire-proof paint and fireproofing function study mechanism》The fireproof coating that one text is obtained
Containing substantial amounts of phosphate group, water absorption rate is big, easily causes coating and metal erosion, expansible graphite and organic macromolecule phase
Capacitive is poor, the insufficient strength of coating, needs to improve, in addition it is also necessary to improve aging resistance, the fire resistance of coating.
