Description
Technical field
The present invention relates to a kind of new coating technical field, in particular to a kind of have the novel multiple of anti-corrosion fireproof
Steel structural traverse and the preparation method of the anticorrosion of steel structure fireproof coating are protected in cyclization.
Background technique
A kind of form of the steel construction as building structure, is widely used in construction industry.Due to steel construction itself
Non-ignitable, the fire-proof and thermal-insulation protection problem of steel construction was once once being ignored by people.Shutdown is reported and had according to domestic and international relevant information
The test of structure and statistics show that the fire resistance of steel building is poor compared with masonry structure and reinforced concrete structure.Steel
Mechanical strength reduced with the raising of temperature, at 500 DEG C or so, intensity drops to 40%~50%, the mechanical property of steel
Can, all decline rapidly such as yield point, compression strength, elasticity modulus and weight bearing power loses enabling capabilities quickly, causes
Building collapses.
The coating of usual structural steelwork application is divided into anticorrosive coating and fireproof coating, is painted on steel construction table
Face plays respective specific function, plays the protective effect to steel construction.Anticorrosive coating primarily serves antiseptic and rustproof, resists
Erosion of the external harmful substance to steel construction.The effect of fireproof coating is to play the work of isolation in protected object body surface face
With delaying the time of building collapse, to succour and fire extinguishing wins valuable time.
Fire-resistant coating for steel structure brushes or is sprayed on steel structure surface, plays fire-proof and thermal-insulation, prevents steel in a fire
It is brought rapidly up and reduces intensity, steel construction is avoided to lose enabling capabilities and building is caused to collapse.Fire-resistant coating for steel structure belongs to
Important species in fire proofing material accounts for about the 2/3 of entire fire proofing material dosage.China is risen by the research of fire-resistant coating for steel structure
In last century the eighties.With the foundation of China's fire codes, perfect, research produces and using also increasingly by industry
Pay attention on boundary.
But recently since fireproof coating finishing coat is incompatible with anticorrosive paint priming paint, intermediate coat, generation quality accident again and again is made
Rust, coating shedding failure are returned at steel construction matrix.Two kinds of coating application complex process simultaneously, cannot mix painting, interval time is long, shadow
Ring construction speed.Fireproof coating does not have antirust, anticorrosion function generally.
Therefore, industry is highly desirable to the improvement by formula, solves the poor compatibility generated between its different coating, easily takes off
Problem is fallen, it is strong to provide a kind of strong fire resisting, good weatherability, wearability, by antirust, anti-corrosive erosion resisting coating and the difunctional unification of fire resistant coating
Anticorrosion of steel structure fireproof coating.
Summary of the invention
The purpose of the present invention is to provide a kind of composite anti-corrosive fireproof steel structural traverses, to overcome above-mentioned existing skill
Art there are the problem of.
To achieve the above object, the present invention provides the following technical scheme that
The present invention provides a kind of anti-corrosion fire preventing steel structure coating, including following raw material forms in parts by weight:
The preferred Aluminate of coupling agent, the film forming help the preferred halogenated alkyl phosphate of drug.
Present invention simultaneously provides a kind of preparation methods of anti-corrosion fire preventing steel structure coating:
The first step, by fatty acid monoethanolamide ether carboxylic acid sodium, hexamethylenetetramine, water and, polyalcohol and polyisocyanates
Mixing, carries out heating reaction；
Second step, is added triethylamine, coupling agent Aluminate, and coalescing agent halogenated alkyl phosphate carries out high speed dispersion, system
Obtain silane-modified waterborne polyurethane resin；
Third step adds silicon nitride, titanium dioxide, is stirred 30~60 minutes, can be prepared by this hair after mixing
Bright anti-corrosion fireproof coating.
The above-mentioned first step is to third step controlled at 60 ± 2 DEG C.
Compared with prior art, the beneficial effects of the present invention are:
This anti-corrosion fire preventing steel structure coating of the invention avoids incompatible, caducous problem, reduces construction work
Sequence greatly reduces engineering cost.The coating has excellent Corrosion Protection, also has antistatic, water resistance, scrub resistance
Can, it can effectively have the function that fire-proof and thermal-insulation, steel is prevented to be brought rapidly up in a fire and reduce intensity.Moreover, preparation work
Skill is simple, it is pollution-free, low in cost, be widely used.This steel structural traverse designed by the present invention, in the actual engineering construction
Coating layer thickness can be applied by design requirement, 10 times of the expansion multiplying power of this coating, fire endurance was up to 120 minutes.The coating
Prepare that facility is simple, production process is pollution-free, application prospect is extensive.
Specific embodiment
In order to make those skilled in the art more fully understand the present invention, With reference to embodiment to the skill of this patent
Art scheme is described in more detail.
The present invention uses organosilane-modified waterborne polyurethane resin as basic resin, instead of traditional oiliness tree
Rouge.And efficient antiseptic is added, the homogeneous carboxy methylation synthetic environment friendly fatty acid monoethanolamide ether of fatty acid monoethanolamide
The addition application of carboxylic acid sodium, hexamethylenetetramine etc. realizes VOC zero-emission.This product high temperature creep-resisting ability is strong, thermal stability
Height, oxidation resistance is good, and has good chemical stability, is resistant to resistance to most of inorganic acids and 30% caustic soda below is molten
Liquid, also can almost all organic acid corrosion.
It is various multiple that the present invention adds silicon nitride powder, titanium dioxide, fatty acid monoethanolamide ether carboxylic acid sodium, hexamethylenetetramine
The proportion being combined point carries out collaboration optimization, and the anticorrosive fire-proof for improving novel fire resistant environmental protection steel structural traverse is difunctional.
