Abstract
The present invention relates to a preparation method for steel structure fire bricks and belongs to the field of fireproof materials. According to the method, the soft kaolin and the nano-hole volcanic rock material are mixed and then crushed to form mixed powder materials. The mixed powder materials are blended in water to form a powder syrup. The powder syrup is placed in a mold cavity to be subjected to the treatments of de-molding, fettling and airing. After a resultant product is completely dried, the glaze is applied onto the inner and outer surfaces of the resultant product. After that, CaCO3 is rolled into CaCO3 powders and the CaCO3 powders are placed in a hollow structure. Then circular holes are sealed by the Kaolin powder syrup. Finally, an obtained product is fired, taken out and dried to obtain a steel structure fire brick having the fireproof function. According to the technical scheme of the invention, the fireproof requirement of the external environment on the fireproof brick can be met, and the thermal insulation property of the brick is ensured to be excellent by CO2. The duration of the fire resistance of the fire brick can last for 10-15 hours. The fire brick is formed through the one-shot firing and molding process, thus saving the cost and the time.
Description
Technical field
The present invention relates to a kind of preparation method of steel structure fireproofing brick, belong to fire-retardant material field.
Background technology
Steel are a kind of material of construction that can not burn, the characteristics such as it has antidetonation, bending resistance; In actual applications, steel both can increase the weight bearing power of buildings relatively, also can meet the needs of architectural design aesthetic feeling moulding; Also avoid the material of construction such as concrete can not bend, the defect of stretching; Therefore steel receive the favor of building trade, individual layer, multilayer, skyscraper, factory building, storehouse, waiting room, and boarding lounge etc. adopt steel all very general; But steel exist again some defects being difficult to avoid as material of construction in fire prevention, its mechanical property, as yield-point, tension and Young's modulus etc. all can Yin Wendu rising and sharply decline.
The casting concrete of current use or build refractory brick by laying bricks or stones and close steel construction completely fire prevention process is carried out to it, but common concrete fireproof takes up room larger, cannot adapt to instantly to the demand of space structure, general fire proofing tile just can reach 1.5 ~ 3h fire endurance when its thickness reaches 5 ~ 10cm simultaneously, so need one lighter, the while that volume being little, the good fire proofing tile of resistivity against fire is necessary.
Summary of the invention
The technical problem that the present invention mainly solves is: large for common fire proofing tile volume, the problem that fire resistance is poor, provides a kind of by ceramic heat resistant and inner CO
2have good heat insulating effect and carry out synergistic method architecture protection thing steel construction, this material produce cost is low, and fire resistance is good, and can reach fire endurance is 10 ~ 15h.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
(1) by mass percentage, choose the soft kaolin of 70 ~ 75%, 25 ~ 30% milli hole volcanics materials carry out mixing it are pulverized into 300 ~ 350 object kaolin volcanics mixed powders by high pressure rolling device, kaolin volcanics powder mix water is reconciled into the powder slurry that solid weight accounts for 80%, die cavity put into by the powder slurry above-mentioned mediation completed, and dries in the air and carry out demoulding process after half-dried;
(2) carry out repaired biscuit to the sun-dried mud brick after the demoulding, the mixing sun-dried mud brick thickness after reparation is the hollow structure of 20mm, simultaneously inside and outside smooth surface, and internal structure length, width and height are respectively 150 × 50 × 10mm, and bottom has a diameter to be the circular hole of 10mm;
(3) carry out airing outside the sun-dried mud brick holding chamber after being completed by repaired biscuit, after its complete drying, obtain the mixing sun-dried mud brick of hollow structure, subsequently to glazing inside and outside it, ensure that the glazing of outer wall inwall is even, leave standstill after glazing completes dry for subsequent use;
(4) by CaCO
3undertaken being rolled into 200 ~ 250 object CaCO by high pressure rolling device
3powder, is inserted in hollow structure, ensures CaCO
3powder fills up in whole hollow structure, simultaneously with kaolin powder slurry sealing circular hole;
(5) by above-mentioned injection CaCO
3the mixing sun-dried mud brick of powder is transported in ceramic sintering kiln to be fired, and sintering temperature is 1200 DEG C, after the firing time reaches 24 hours, takes out subsequently, dries, and obtains the steel structure fireproofing brick with fire-proof function.
The glaze paint of described glazing is that mark is counted by weight: the feldspar of 18 ~ 20 parts, the CaCO of 20 ~ 22 parts
3, the MgCO of 1 ~ 5 part
3, the kaolin of 25 ~ 29 parts, the titanium oxide of the silica of 25 ~ 28 parts and 2 ~ 5 parts.
Principle of the present invention is: in the inner oxygenizement by calcium carbonate of fire proofing tile, make its inside be filled with CO
2, CO
2effectively can be incubated with heat insulation, effectively prevent further thermal conduction and the thermal radiation of temperature, ensure that the performance of fire proofing tile excellence.
