Abstract

The invention discloses a high-strength environment-friendly fiber gypsum board and a preparation method thereof. Iron powder 10‑20 parts, fly ash 10‑20 parts, expanded perlite 8‑16 parts, tourmaline powder 6‑15 parts, glass fiber 10‑20 parts, aluminum silicate fiber 5‑15 parts, tea polyphenol 3 ‑8 parts, 1‑5 parts of adhesive, 4‑10 parts of water glass and 45‑65 parts of water. The invention provides a high-strength environment-friendly fiber gypsum board and a preparation method thereof. The fiber gypsum board has high strength, is not easy to crack, has a low thermal conductivity, and has the function of adjusting the indoor environment. At the same time, the fiber gypsum board has a simple preparation process and is easy to realize. Suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a high-strength environment-friendly fiber gypsum board and a preparation method thereof. Background technique [0002] In recent years, gypsum board has been favored by users for its advantages of light weight, non-combustibility, and "breathing" function. It is widely used in interior wall decoration of houses. It is easy to break, and the wall is easy to crack after installation, which brings inconvenience to the construction; it also causes huge losses. Although fibers are added to reinforce the gypsum board in the prior art, the mechanical strength of the gypsum board still cannot meet the requirements of many application occasions due to the problem of unreasonable fiber layout. [0003] Gypsum board is widely used in various buildings such as residential buildings, office buildings, shops, hotels and industrial plants for interior partition walls, w...
