Abstract

The invention discloses a geopolymer-based light wallboard and a preparation method. The geopolymer-based light wallboard is composed of high-strength asbestos-fiber-free cement plates on two sides and geopolymer-based foamed concrete in the middle. The geopolymer-based foamed concrete is prepared from, by mass, 5-32 parts of bentonite fine powder, 3-28 parts of iron tailings slag fine powder, 5-17 parts of expanded vermiculite powder, 5-25 parts of alkaline activator, 0.05-0.8 part of ecological fiber, 0.05-1.0 part of foaming agent, 0.2-1.0 part of thickener and 10-30 parts of water. The bentonite fine powder is formed by smashing and grinding bentonite raw ore, particle size is 1.2-5.8 micrometers, density is 1.7-2.5 g/cm<2>, pores are thin, small and uniform and not connected mutually, the bentonite fine powder is excellent in sound-isolation, heat-insulation and flame-retardant properties, and the service life of the bentonite fine powder is the same to that of a body structure. Low weight and high strength are achieved, and the specific gravity is low, so that the foamed concrete is tough. Besides, China has rich ecological plant resources, a lot of resources can be saved, the survival environment of human is benefited, and the strength and the durability of the light wallboard are improved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a geopolymer-based lightweight wallboard and a preparation method thereof. Background technique [0002] With the improvement of people's awareness of environmental protection and energy conservation and the regulations of national policies, various industries have increased their research and development efforts in environmental protection and energy conservation to better protect the environment in which human beings live. [0003] Geopolymer is one of the non-metallic materials that has been studied very actively in the world in recent years. It is a new type of inorganic polymer material obtained by chemical reaction at a lower temperature with silicon-containing solid materials such as clay, industrial waste or slag as the main raw material. It can replace cement for construction, Roads, artificial islands, prefabricated components, refractory materia...
