Abstract

The invention discloses an environment-friendly preparation process of a light magnesium oxysulfate wall material, which comprises the following steps: S1, mixing light calcined magnesia powder, a magnesium sulfate solution and a magnesium oxysulfate modifier to obtain a first mixture; S2, mixing polystyrene particles, a foaming agent, an active filler, foaming agent foam and the first mixture toobtain a second mixture; S3, injecting fibers and the second mixture into a mold of which the bottom is provided with a layer of laid glass fiber net, sending the material into a forming machine for natural forming, and laying a layer of glass fiber net at the top of the mold; and S4, conducting demolding, naturally forming the sample at normal temperature, and then naturally conducting curing. Inthe environment-friendly preparation process of the light magnesium oxysulfate wall material, no pollutant is discharged, and the light magnesium oxysulfate wall material has good environment-friendly performance. The light magnesium oxysulfate wall material produced by the invention has the advantages of good sound insulation, bending resistance, bearing resistance and anti-halogenation effect,the fire resistance reaches the A1-level standard, and meanwhile, the requirements of light products are met.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an environmentally friendly preparation process for light magnesium oxysulfide wall materials. Background technique [0002] With the continuous development of science and technology, the demand for environmentally friendly and non-toxic decorative materials has gradually increased, and people have put forward higher requirements for building materials, and the original materials are becoming less and less suitable for people's needs. The existing magnesium oxysulfide wall materials have the following disadvantages: secondary pollution caused by toxic and non-degradable inorganic materials, cumbersome construction, high cost, no high temperature resistance, no acid and alkali resistance, and no corrosion resistance. Therefore, traditional building materials emit a large amount of pollutants during the production process, which seriously damages the environment. Contents of the...
