Fire-resistant inorganic fiber composite ceiling board and production method thereof

Abstract

The invention discloses a fire-resistant inorganic fiber composite ceiling board. The adjacent ceiling boards are in lap joint on a T-shaped keel. The fire-resistant inorganic fiber composite ceiling board comprises a main body, a concave connecting element, a convex connecting element and support frames, wherein the main body comprises a filling material layer, an upper face plate and a lower face plate; the filling material layer is formed by inorganic fiber filling materials and inorganic fiber spray coating bonding agents through matched synchronous spray coating filling; the two support frames are respectively embedded between the upper face plate and the lower face plate; the convex connecting element and the concave connecting element are also embedded between the upper face plate and the lower face plate; and the convex connecting element and the concave connecting element are provided with installing grooves. The invention also discloses a production method of the ceiling board. The production method comprises the major steps of reserved splicing, mould installing, spray coating filling and installation reservation. The invention relates to the field of building and provides the fire-resistant inorganic fiber composite ceiling board and the mould pressing spray coating filling production method thereof. The fire-resistant inorganic fiber composite ceiling board has the advantages that the heat insulation and sound isolation performance is high; the fire-resistant performance is high; the mounting and the dismounting are convenient; and the cyclic utilization can be realized.

Description

technical field [0001] The invention relates to the construction field, in particular to a refractory inorganic fiber composite ceiling board and a production method thereof. Background technique [0002] The living or working environment of the house needs top decoration. Simply put, it refers to the decoration of the ceiling. Artistic image of interior space. In addition, the suspended ceiling has the functions of heat preservation, heat insulation, sound insulation and sound absorption, and it is also the hidden layer of electrical, ventilation and air conditioning, communication and fire protection, alarm pipeline equipment and other projects. In addition to the insulation performance and aesthetics of the suspended ceiling of the house, fire resistance is the most basic and important safety requirement. [0003] The traditional ceiling mode is mostly single-layer ceiling boards such as aluminum gusset boards, gypsum boards, and mineral wool boards. The fixtures instal...

AI Technical Summary

Problems solved by technology

Since the thickness of the above-mentioned ceiling panels generally does not exceed 20mm, the ceiling panels will soften, pulverize and fall off in the event of a fire, and at the same time, the hanging parts or aluminum or steel will soften or even melt at 400 to 600 degrees Celsius, causing the ceiling to collapse. It is difficult to reach the 1h level in the fire resistance level test of the existing technical suspended ceiling
