Problems solved by technology

[0003] The fireproof temperature of traditional building heat insulation boards and inorganic fireproof boards such as tobermelite calcium silicate board and magnesium oxychloride inorganic fireproof board is below 1000 °C, although it can barely meet the "Code for Fire Protection Design of High-rise Civil Buildings" (GB50045-2001) The fire resistance rating of the defined beam is a first-class requirement, but its disadvantages are: high cost, high brittleness, poor waterproof performance, etc.
[0004] At present, there is no inorganic fiber fireproof board specially designed for steel structures and high-rise buildings with a fireproof temperature of 1100 ° C and a fire resistance limit of more than 3 hours, and light fire protection panels for steel structures and high-rise buildings.

Abstract

The present invention is fireproof building board of ceramic fiber, and belongs to the field of ceramic fiber material technology. The fireproof building board of ceramic fiber is produced with aluminum silicate fiber or light refractory stuffing as base material, and through adding one or several kinds of enhancing fiber; adding proper amount of organic binding agent or inorganic binding agent, stuffing and additive; pulping; forming; drying and other steps. The fireproof building board of ceramic fiber is used as the heat insulating board in building, and has high fire rating, high fire resistance, high heat isolating performance, high strength, low density and low cost.

Description

technical field [0001] The invention belongs to the technical field of ceramic fiber materials, and in particular relates to a ceramic fiber building fireproof board. Background technique [0002] Traditional building insulation boards and inorganic fireproof boards, such as glass wool boards, rock wool insulation boards, slag wool insulation boards, mineral wool insulation decorative acoustic ceilings, asbestos boards, cement boards, gypsum boards, perlite boards, vermiculite boards, Tobermorite-type calcium silicate boards, etc., have a fire resistance temperature below 800°C, which cannot meet the requirements of the national standard "Code for Fire Protection Design of High-Rise Civil Buildings" (GB50045-2001), which defines the fire resistance level of beams as Class I (no The burning body is greater than 2.0h); it does not meet the requirements in the "Code for Design of Fire Protection of High-rise Civil Buildings" (GB50045-2001) that the fire resistance level of the ...
