Background technology
Most of framework of modernization high level and building uses steel construction, although the steel as supporting member have
Have the advantages that intensity it is high, from heavy and light, load-bearing capacity is big, anti-seismic performance is good, easy construction, pollution-free, reusable edible, still, its
Thermal conductivity factor is big【52W/(m·K)】Once running into fire, its temperature can rise to 700 DEG C in 10-15min, considerably beyond
The critical-temperature (540 DEG C) of itself, now, lose and hold because the yield strength of steel drastically drops to 40% or so of normal-temperature
Power is carried, building can be caused to collapse.At present, China carries out coating protection using fire-resistant coating for steel structure to it more.For high level
The support column of civil buildings, general industry and the post that multilayer is supported in civil buildings, large-span steel factory building, petrochemical industry work
Journey etc., protected more using thick matter fire-resistant coating for steel structure of the fire endurance more than more than 2.5h.But thickness of the prior art
The fireproof coating of formed steel construction, although fire endurance more than 3 hours, coating layer thickness 25mm or so, because coating layer thickness is thick,
In work progress easily cracking, hollowing phenomena such as.Simultaneously in work progress, paint film is inevitably damaged, in order to
Phenomena such as preventing thicker fire-resistant coating for steel structure easily cracking in work progress, hollowing and the use longevity of fireproof coating
Life, improve fireproof coating function and be very important.
The content of the invention
For these reasons, applicant is by studying for many years, obtain using 42.5R portland cements and polyethylene glycol 2000 as
Compound adhesive, the fire-resistant coating for steel structure using alumina silicate fibre inorganic material as the thick coated type of crack resistence thermal insulating filling should
Thicker fireproof coating is a kind of low cost, excellent performance, easy for construction, good endurance, has the Novel ring of broad development prospect
Friendly coating, this product have that bond strength, water-tolerant, resistance to acids and bases are good, safe and non-toxic, smoke amount is few, cracking resistance and crack resistence
Property good, thick coated type steel structure fire-proof paint that fire protecting performance is excellent, the flame-proof finishing that can be widely applied to indoor and outdoor steel construction protects
Shield.
