Description
Technical field
The present invention relates to a kind of superthin expansion steel structure fireproof coating and preparation method thereof, belongs to fireproof coating technology neck
Domain.
Background technology
Steel are a kind of construction materials that will not be burnt, and it has the characteristics such as antidetonation, bending resistance.But steel are as building
Material in terms of fire prevention again be difficult to avoid that in the presence of some the defects of, its mechanical performance, such as yield point, tension and modulus of elasticity
Can drastically it decline because of the rise of temperature.Steel construction will generally lose bearing capacity in 450~650 DEG C of temperature, occur
Very big deformation, cause steel column, girder steel bending, as a result can not be continuing with because of excessive deformation, typically be not added with the steel of protection
The fire endurance of structure is 15 minutes or so.The length of this time is also relevant with the speed of component heat absorption.Make steel construction material
In terms of material overcomes the shortcomings of fire prevention in actual applications, it is necessary to carry out fire prevention processing, its purpose is exactly by the fire resisting pole of steel construction
Limit brings up to limit range as defined in design specification.Because the spatial modelling of steel building is extremely complex, if with others
Method is extremely difficult to the requirement of thorough flameproof protection.Only its external coating chemical defence coating could thoroughly play fireproof mesh
, and prevent trouble before it happens.In addition, protective coating has lot of advantages, such as from heavy and light, low cost, easy for construction.Therefore,
It has irreplaceable important function compared with other means of defences, and is a kind of economical and practical, preferable reliable fire prevention
Measure.Now, up to 90% steel construction is all to carry out flameproof protection using this fireproof coating method.If according to using thick
Degree is classified to fireproof coating, and it is broadly divided into three classes, and it is thicker fire-resistant coating for steel structure, thin section steel structure fire prevention respectively
Coating and super-thin steel structure fire-proof paint.And wherein, super-thin steel structure fire-proof paint has fine size, coating by it
The features such as thin and good decorative property, steel structure fireproofing requirement can not only be met, can also meet the high-decoration requirement of people.
The coating layer thickness of superthin expansion steel structure fireproof coating is less than 3 mm.Hair is expanded rapidly when being characterized in heated
Bubble, form a kind of fine and close fire proof heat-insulation layer.Because this super-thin steel structure fire-proof paint has, coating is thin, decorative appearance
The advantages that good, enjoy market to pay attention at present, be the development trend of fire-resistant coating for steel structure.
Superthin expansion steel structure fireproof coating is by base-material, fire proofing, foaming agent, expanded material, filler and auxiliary agent
Formed Deng composition, wherein fire proofing, foaming agent, expanded material are the Intumescent Retardant Systems of fireproof coating.Now, in the market is adopted
It is melamine, APP and pentaerythrite with more Intumescent Retardant System.But APP has very strong suction
Tide and water solubility, it will severely impacted the performance of fireproof coating, such as weatherability, water resistance；And melamine is in height
Lower decompose of temperature can produce harmful cyanide gas, pollute environment, damage the health of people.And traditional ultra-thin fire retardant coating
Expanded material expansion rate is low after meeting fire, it is impossible to significantly plays the fire resistance of fire proofing so that steel fire resistance period is not
Long, this is also super-thin steel structure fire-proof paint urgent problem to be solved instantly.
Fire proofing and expanded material used herein are nano shape, and nano material has high specific surface area,
By the way that nano material is uniformly mixed in coating, the utilization rate of material can be greatly improved, so as to improve flame retardant effect.In addition
Using nano-graphite as expanded material, not only with anti-flammability, resistance to ag(e)ing and weatherability etc. with outstanding advantages, and
And compared with common expanded graphite, frothing percentage greatly improved.
The present invention uses acrylic acid series water-based adhesive, and compared with its solvent-borne type or other water-based adhesives, it has to be non-
Solvent, nonhazardous or flammability hazard, there is good water resistance and alkali resistance, and have good cementability to Steel material.Separately
It is outer to replace melamine as foaming agent to it also avoid melamine and decompose at high temperature that harmful cyaniding is produced using urea
The phenomenon of thing gas, meet green requirement.
The content of the invention
A kind of superthin expansion steel structure fireproof coating and preparation method thereof, by the present invention in that being made with nano expanded graphite
For expanding material and a variety of flame retardant nano-materials are used in mixed way, to improve fire resistance and fire resistance period.More importantly use
Water paint, the organic matters such as melamine, safety and environmental protection are not contained.It is made up of the component of following weight：Acrylic water-based bonds
Agent 30-60%, nano-zinc borate 1-10%, nanmeter antimong trioxide 1-10%, nano titanium oxide 0.2-8%, nano expanded graphite

Material, the effect of its each component is as follows, and acrylic water-based adhesive uses as the binding agent and film forming matter of coating.Nano-zinc borate
Fire retardant is used as, and by coordinating with nanometer antimony trioxide to improve flame retardant effect.Nano titanium oxide is as filling material
Material and modifying agent, the mechanical strength and weather resistance of coating can be improved, improve the effect of coating anti-ultraviolet aging again.Nanometer is swollen
Swollen graphite is used as expanded material, and urea uses as foaming agent, is promoted when fire occurs by the foaming effect of urea
Expanded graphite expands, so as to improve coating fire resistance.Deionized water uses as solvent, for disperseing nano-zinc borate, receiving
Rice antimony trioxide, nano titanium oxide and nano expanded graphite, and nano material is existed by adding dispersant and antisettling agent
