Problems solved by technology

At present, the gypsum boards on the market mainly include paper gypsum boards, decorative gypsum boards, and gypsum hollow slats. However, these types of gypsum boards do not have the function of electromagnetic shielding. After solid waste and noise pollution, the fifth largest public hazard of human beings, the harm to human life and work and electrical equipment is immeasurable. Therefore, it is necessary to improve the new building material gypsum board

Description

technical field [0001] The invention relates to the technical field of gypsum board building materials, in particular to a lightweight gypsum board with electromagnetic shielding function and a preparation method thereof. Background technique [0002] Gypsum board is a new type of building material made of building gypsum as the main raw material. It has the characteristics of light weight, convenient processing, sound insulation and flame retardancy, and good compression and bending resistance. It is one of the new lightweight boards that are currently being developed. Gypsum boards have been widely used in interior partition walls, wall cladding panels (instead of wall plastering layers), ceilings, sound-absorbing boards, ground base boards and various types of buildings such as residences, office buildings, shops, hotels and industrial plants. Decorative panels, etc. At present, the gypsum boards on the market mainly include paper-faced gypsum boards, decorative gypsum b...
