Beschreibung
Zusammenfassung:	A fire-resistant gypsum board comprises a fire-resistant base layer, paper surface layers and a plurality of combined type grid rib layers solidified in the fire-resistant base layer, wherein the paper surface layers are bonded to a first outer surface and a second outer surface of the fire-resistant base layer respectively; each combined type grid rib layer comprises multiple layers of fiberglass meshes which form the combined type grid rib layer in a stacking manner. The fire-resistant gypsum board adopts the structure of multiple layers of combined type grid rib layers formed by the fiberglass meshes with high heat resistance, so that the monofilament number and grid density of single fiberglass bundle of the grid rib layers are not limited by a fiberglass mesh production technology, and levels of the strength, the burning stability and the duration of fire resistance of a fire-resistant gypsum board product are increased effectively.
