Composite magnesite partition wall plate and production method thereof

The invention relates to the field of building materials, in particular to a composite magnesite partition wall plate and a production method thereof. The composite magnesite partition wall plate provided by the invention sequentially comprises a magnesite surface plate, a polystyrene foam magnesite slurry layer and a magnesite substrate plate, wherein the polystyrene foam magnesite slurry layer is formed by mixing magnesite slurry and polystyrene foam particles; and the magnesite plate and the polystyrene foam magnesite slurry are integrally pressed through a mould. Compared with the prior art, the composite magnesite partition wall plate provided by the invention has the effects of light weight, sound insulation, heat insulation, pressure resistance, fire prevention, fast installation, space saving and the like.
