Method for producing building lightweight wall board by using tailings powder as raw material

Abstract

The invention relates to a method for producing a building lightweight wall board by using tailings powder as a raw material, which comprises the following steps: (1) dissolving magnesium chloride into solution; (2) mixing and stirring magnesium oxide with the tailings powder, the solution of the magnesium chloride and an environment-friendly additive until the mixture is even; (3) frothing a foaming agent, then pouring the frothed foaming agent into the mixture, and continuously stirring the frothed foaming agent and the mixture evenly; (4) putting a material prepared by the previous steps into a mold, and maintaining the mold; and (5) after maintaining the mold, dismounting the wall board in the mold, and piling up and preserving the wall board. The method has the advantages of: 1, according with the demands on the sustainable development of the national recycling economy; 2, according with the demands on national establishment of economical building material enterprises; and 3, comprehensively using resources and changing wastes into valuable.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a method for producing light-weight building wall panels using tailings powder as a raw material. Background technique [0002] As people's demand for energy-saving green buildings is increasing, the problems of high energy consumption in buildings and the destruction of ecological resources by bricks, tiles and cement used in traditional buildings have increasingly become the focus of attention of the world and society. my country has a large population, and the area of ​​houses built every year is as high as 1.6 billion to 2 billion square meters, which exceeds the sum of the annual building areas of all developed countries. However, most of the domestic wall material manufacturers currently use clay, gravel, sand and light aggregates as Filling, which belongs to the production of building materials that destroy resources, does not conform to the national development strategy. ...
