Abstract
The invention provides antimagnetic plasterboard applicable to high-humidity environments. The antimagnetic plasterboard is mainly prepared from the raw materials, i.e., coir fibers, a foamer, plaster clinker, graphene oxide, a humectant and causticized white clay. According to the antimagnetic plasterboard applicable to the high-humidity environments, the coir fibers and the causticized white clay are added on the basis of the conventional plaster clinker and foamer, so that the waterproof performance of the plasterboard is improved, and a very good wetted bonding effect can be achieved without adding additives such as CMC powder; by adding the graphene oxide, the strength of the plasterboard can be further improved; in order to improve the dispersion effect in the entire system, the humectant is required to be added, and proven by a large number of experiments, a very good dispersion effect can be achieved through adding a small amount of humectant Hyonic PE-100; after basalt fibers are added, the plasterboard has a very good screening effect on electromagnetic waves with the frequency band of 8GHz to 16GHz. The antimagnetic plasterboard applicable to the high-humidity environments, provided by the invention, is low in cost and high in strength, particularly, has very good bonding strength in the high-humidity environments and is free of powder falling in long-term use, and the electromagnetic screening effect is good.
Description
technical field [0001] The invention relates to the field of building materials, in particular to an antimagnetic gypsum board suitable for high-humidity environments and a preparation method thereof. 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. It is one of the new lightweight panels that are currently being developed. Gypsum boards have been widely used in interior partition walls, wall cladding panels (replacing plastering layers), ceilings, sound-absorbing panels, ground floor panels and various Decorative panels, etc. [0003] Compared with traditional interior decoration materials, gypsum board has the following advantages: [0004] (1) Low production energy consumption. Gypsum, the binder used in the production of gypsum boards, has 78% lower energy co...
