Abstract

The invention discloses an environment-friendly nontoxic gypsum board which is prepared from the following raw materials in parts by weight: 8-14 parts of mineral cotton, 45-48 parts of quicklime, 7-9 parts of superfine sand, 13-16 parts of glass fiber, 6-8 parts of iron oxide powder, 1-4 parts of plant ash, 11-14 parts of water glass, 11-14 parts of wood fiber, 7-9 parts of expanded perlite, 6-10 parts of calcium carbonate powder and 35-40 parts of water. The environment-friendly nontoxic gypsum board contains no harmful substance, and is high in strength, strong in anti-cracking ability, non-toxic and harmless and good in water resistance.

Description

technical field [0001] The invention relates to the technical field of inorganic non-metallic materials, in particular to an environment-friendly non-toxic gypsum board. Background technique [0002] Due to its light weight, high strength, thin thickness, convenient processing, sound insulation, heat insulation and fire resistance, gypsum board is widely used in interior partition walls and walls of various buildings such as residences, office buildings, shops, hotels and industrial plants. Cladding panels, ceilings, sound-absorbing panels, ground-based panels and various decorative panels, etc. Because it is in an indoor environment, its safety requirements are very high. The existing gypsum boards contain chemical elements harmful to the human body. After the decoration is completed or when encountering high temperatures, they are very easy to volatilize and pose a threat to human health. Contents of the invention [0003] In order to solve the above existing problems, ...
