Abstract

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.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a composite magnesite partition board and a production method thereof. Background technique [0002] In recent years, with the implementation of my country's energy-saving emission reduction and environmental improvement policies, the development of building materials, especially wall materials for thermal insulation and heat insulation has become an irresistible trend. Existing partition boards usually use silicon-calcium boards As the base material, the thermal insulation, sound insulation, and compressive strength of this type of partition board are not ideal. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a composite magnesite partition board to achieve better effects of compression resistance and fire prevention. [0004] Another object of the present invention is to provide...
