Abstract
The invention discloses an environment-friendly moisture-proof plasterboard which is prepared from the following raw materials in parts by mass: 25 to 35 parts of plaster, 8 to 11 parts of wood fiber, 7 to 9 parts of expanded perlite, 4 to 6 parts of calcium carbonate powder, 7 to 12 parts of borax, 3 to 5 parts of cement, 4 to 6 parts of alum expanding agent, 6 to 9 parts of stearic acid latex, 9 to 12 parts of polyvinyl alcohol emulsion and 8 to 10 parts of paraffin emulsion. The environment-friendly moisture-proof plasterboard disclosed by the invention has the advantages of high moisture resistance, high strength and hardness, no cracking, good economy, high environment-friendly property, flame retardance and fire resistance.
Description
technical field [0001] The invention relates to the technical field of building materials, in particular to an environment-friendly moisture-proof gypsum board. Background technique [0002] Gypsum board is a material made of building gypsum as the main raw material. It is a building material with light weight, high strength, thin thickness, convenient processing, sound insulation, heat insulation and fire resistance. As one of the new lightweight panels, gypsum boards have been widely used in interior partition walls, wall cladding panels, ceilings, sound-absorbing panels, ground floor panels and various Decorative panels, etc. The existing gypsum boards have poor moisture resistance, which leads to a decrease in the strength and hardness of the damp gypsum boards, affecting normal use. Contents of the invention [0003] In order to solve the above existing problems, the present invention provides an environment-friendly moisture-proof gypsum board with strong moisture-...
