The flame-retardant material is mainly made of inorganic materials, has a noncombustible property, and the weight is light, so that the load on a steel structure is not increased, and meanwhile, the structure of the flame-retardant material is compact and impact-resistant after high-temperature sintering, and the duration of fire resistant is more than 3 hours according to the proofness of fire resistance experiments.
Description
Technical field
The present invention relates to building material field, particularly relate to building fireproof meterial field.
Background technology
It is high, fast from heavy and light, the good construction speed of anti-seismic performance that steel building has intensity, the series of advantages such as structure footprint is few, industrialization degree is high, and it is compared with concrete structure, environmental protection and be more conducive to the development of architectural industrialization.But it is not from fire prevention angle, although steel construction is non-combustible component, very fire-resistant.The crystal inside tissue of steel is very responsive to temperature, temperature raises or reduces and steel performance power all can be made to change, and steel construction will lose supporting capacity when 450-650 DEG C usually, and very large deformation occurs, cause steel column, girder steel bending, result can not continue to use because being out of shape excessive.The U.S. 9.11 terrorist incident shows, steel construction is not fire-resistant, is that the World Trade Center caves in, the weight reasons of a large amount of injures and deaths of personnel.
The index weighing steel structure fire-resistant performance is fire endurance, and in standard fire, when burning to 1450 DEG C, back of the body temperature is no more than 550 DEG C, holding structure complete the maintained time.Steel structure fire-resistant experiment obtains steel beam column fire endurance and is: t=0.54 (Ts-50) (F/V)
-0.6
In formula: t-fire endurance, (min)
Ts-steel beam column temperature, (DEG C)
The sectional area coefficient of F/V-component, the fire area and its body that equal unit length component protect long-pending ratio, m
-1.
Experiment shows, Steel Fire Resistance Rating is low, only has 15-30min, and fireproof jointing sheath is easily destroyed, and determines steel building and must pay attention to fire safety problem.Steel building flameproof protection method will improve steel structure fireproofing performance, will intercept the transmission of fire heat to steel, to delay the speed of steel temperature rise, postpones the time of critical temperature when steel beam column reaches destruction.At present, normally take both at home and abroad directly do not roasted by flame way protection steel construction such as steel structure surface sprayed fire proofing coating or parcel refractory materialss and improve its fire-resistance capacity.Experience shows, quality, timeliness, the coating cohesive force of steel structure fireproofing spraying, use in whether have loosening, cracking or whether be subject to large impact, vibrations etc. and directly can have influence on the fire safety of steel beam column, and the fire endurance of 1.5 hours can only be reached.The domestic refractory materials for wrapping up steel construction mostly is the PLASTIC LAMINATED of the non-combustible material such as fiber reinforced cement board (as TK plate, FC plate), plasterboard, calcium silicate board, vermiculite board at present, but these refractory materialss but not impact resistance, and from great, add the load of steel construction.
Summary of the invention
The present invention is directed to above-mentioned defect, a kind of fireproof meterial for wrapping up steel construction is provided.
The preparation method of fireproof meterial, it is characterized in that by high temperature resistant silica gel, ceramics powder and stiffening agent mix after through twice high temperature sintering.
