Damping glass magnesium fireproof plate with sound insulation and noise reduction functions

The utility model belongs to the technical field of glass magnesium fireproof plates, and particularly relates to a shock-absorbing glass magnesium fireproof plate with sound insulation and noise reduction, a glass magnesium fireproof plate body comprises a magnesium oxide layer plate, a plant fiber plate and a PU (polyurethane) foaming plate which are bonded with one another, and the magnesium oxide layer plate, the plant fiber plate and the PU foaming plate are all of a porous structure. The magnesium oxide laminate and the plant fiber board are formed by pressing, a noise reduction groove is formed in the upper surface of the magnesium oxide laminate, and the plant fiber board is bonded between the magnesium oxide laminate and the PU foaming board; the magnesium oxide laminate, the plant fiber board and the PU foam board form the magnesium oxide fireproof board body, so that the magnesium oxide fireproof board body is buffered and damped through the PU foam board during use, and meanwhile, the hardness of
