Description

TECHNICAL FIELD

[0001] The utility model belongs to building board technical field, concretely relates to a fire -resistant high strength hydrophobic composite board structure. BACKGROUND

[0002] Fly ash is a kind of fly ash hollow ball that can float on the water surface, thin wall hollow, very light, and its chemical composition is mainly silicon dioxide and aluminum oxide. Fly ash can reduce density, heat insulation, improve fire resistance and strength in magnesium sulfate composite board composed of active magnesium oxide and magnesium sulfate. However, there are some outstanding problems in the actual use of fly ash-based magnesium sulfate composite board: (1) poor water resistance, when the plate is in a humid environment or is eroded by water, water molecules can enter the plate, which can reduce the mechanical properties and fire resistance of the plate, and even cause structural damage; (2) strength problem, although fly ash can enhance the strength of the plate to some extent, but in the long-term use process, especially under the impact of external force or maintenance bearing pressure, it is easy to damage, break and other problems. These outstanding problems make the fly ash-based magnesium sulfate composite board used in public places such as office buildings, hotels, restaurants, theaters, shopping malls, hospitals and underground parking lots, which need fire exhaust smoke duct, which can affect the service life of the plate, reduce the safety of the whole structure, and even cause safety hazards. CONTENT

[0012] Compared with the prior art, the fire-resistant high-strength hydrophobic composite board structure has the following advantages and beneficial effects:

[0013] The fire-resistant high-strength hydrophobic composite board structure provided by the present application can prevent liquid water from penetrating into the cured board through the surface or capillary action when the board is in a humid environment or is eroded by water, thereby bringing the overall hydrophobic effect to the board. The fiber reinforced layer is laid with a fiber mesh in the middle of the floating bead plate. When the floating bead plate is subjected to external force, the fiber mesh can bear part of the load and disperse the external force to the entire board, thereby improving the overall strength and load-bearing capacity of the board. The fiber mesh is laid with fiber filaments intersecting at 90°. When the board is impacted or bent, the fiber can absorb energy and prevent further expansion of cracks, so that the board deforms to a certain extent without sudden rupture, thereby enhancing the impact resistance and bending resistance of the board.
