Description
Technical field
The invention belongs to technical field of coatings, and in particular to a kind of water super-thin expansion fire-resistant coating for steel structure.
Background technique
Relative to concrete, steel construction has apparent advantage in material property, economic benefit, environmental protection, wide
It is general to be applied to longspan structure, super high-rise building, ordinary residence and office building etc., just gradually become the mainstay material of building.So
And the fire protecting performance of steel construction is poor, largely constrains its development.Theoretically, steel construction can not be protected under full load
The critical-temperature for holding static balancing is 528 DEG C.Fire once occurs for building, and fire scene temperature just can reach 700 DEG C in 10 minutes
More than, exposed steel construction reaches critical-temperature in 10 minutes that fire occurs, will generate plastic deformation and lose and hold
Beijing South Maxpower Technology Co. Ltd's power, and then cause the rapid collapsing of steel building.Fireproof coating can play the role of effective flameproof protection to steel construction,
It can delay the heating of steel construction in a fire, extend its time for reaching critical-temperature, can be fire fighter's fire extinguishing and people
Escape is raced against time, and is had important practical significance.
Fire-resistant coating for steel structure has the characteristics that coating thickness is thin, facing type is good, is widely used in steel construction, is meeting
Under fiery heating condition can rapid expanding to more than ten times of original thickness even decades of times, it is fine and close at one layer of steel structure surface formation
Insulating prevents heat from transmitting to steel construction, plays the function of improving fire endurance.However, unexpansive relative to other
Type fireproof coating, existing fire-resistant coating for steel structure is lower in foaming and intumescing initial stage heat-insulating capability, causes steel construction in heat-insulated guarantor
Temperature rises larger before warm layer expands completely, and whole fire resisting effect is usually not so good as Non-expansive fireproof paint, and most coating
The weight bearing of steel construction is increased larger, application effect is undesirable, using being restricted.
Summary of the invention
The present invention proposes that a kind of water super-thin expansion fire-resistant coating for steel structure, the fireproof coating have coating thin and heat-insulated
The excellent feature of fire protecting performance.
The technical scheme of the present invention is realized as follows:

~6 parts, 8~16 parts of expanded perlite, 0.4~0.8 part of wetting dispersing agent, 0.3~0.6 part of levelling agent, 2~6 parts of coalescing agent
And 20~30 parts of wastewaters with modified calcium sulfate whiskers;Wherein, the wastewaters with modified calcium sulfate whiskers is mainly by calcium sulfate crystal whiskers, nano-titanium dioxide
It is prepared with aluminate coupling agent.
Preferably, the wastewaters with modified calcium sulfate whiskers the preparation method comprises the following steps:
Calcium sulfate crystal whiskers are added in the maleic acid solution of 3~6wt% and carry out ultrasonic disperse, are warming up to 80 DEG C~90
DEG C, then add nano-titanium dioxide and aluminate coupling agent, be stirred to react 2~6h, after centrifugal vacuum it is dry.
Preferably, the mass ratio of the calcium sulfate crystal whiskers and the aluminate coupling agent is 25~35:1, the sulfuric acid
The mass ratio of calcium pyroborate and the nano-titanium dioxide is 2~6:1.
Preferably, the wetting dispersing agent is calgon wetting agent;The levelling agent selects water-and acrylate total
Polymers, fluorine richness polyacrylate copolymer or Siloxane-Oxyalkylene Copolymers polymer are one such.
Preferably, the coalescing agent be propylene glycol phenylate, dipropylene glycol n-butyl ether, Lauryl Alcohol ester, methoxybutanol,
At least one of ethylene glycol monobutyl ether and dipropylene glycol propyl ether.
The preparation method of water super-thin expansion fire-resistant coating for steel structure of the invention:
After mixing the above components evenly according to the proportion.
Beneficial effects of the present invention:
Water super-thin expansion fire-resistant coating for steel structure of the invention is added to mainly by calcium sulfate crystal whiskers, nanometer titanium dioxide
The wastewaters with modified calcium sulfate whiskers that titanium and aluminate coupling agent are prepared, it is high with matrix resin binding force, it is not easy to be precipitated, improve
The refractory heat-insulating performance of fireproof coating.
The present invention uses two kinds of lotions for base-material, has taken into account fire line, anticorrosive property and the dicoration of coating, has avoided list
One lotion makees base-material and bring certain paint film defect.
