Abstract

The invention belongs to the technical field of building decorating materials and relates to a building decorating plate produced by using mineral slag and desulfurized gypsum as main raw materials. The decorating mineral slag and desulfurized gypsum composite plate for a building is prepared from the following raw materials in percentage by weight: 100 parts of mineral slag, 50 to 80 parts of desulfurized gypsum, 0.5 to 3 parts of salt cake, 0.5 to 4 parts of alum, 1 to 5 parts of water glass, 2 to 7 parts of lime hydrate, 1 to 4 parts of chopped glass fiber and 1 to 3 parts of VAE latex, and the mass ratio of the water to the raw materials is 0.40-0.70. The decorating mineral slag and desulfurized gypsum composite plate for the building has the characteristics of light weight, heat insulation, sound insulation, fire resistance, water resistance, worm resistance, breathing function and the like, has the advantages of low production cost, energy conservation and environment friendliness, and is a green and environment-friendly building decorating material.

Description

technical field [0001] The invention belongs to the technical field of new building decoration materials, and relates to a building decoration board produced from slag and desulfurized gypsum as main raw materials. Background technique [0002] In recent years, with the gradual improvement of people's living standards, residential construction has become a new growth point of the domestic economy and a hot spot for consumption. People pay more and more attention to architectural decoration. Among decorative materials, architectural decorative panels are required to have light weight, sound insulation, Heat insulation, waterproof, good processing performance, simple construction method and other properties. At present, the most widely used building decoration board on the market is paper-faced gypsum board. However, the water resistance of the paper-faced gypsum board itself is poor. If it is used in a humid environment for a long time, it will cause yellowing, deformation, ...
