Embodiment 1
[0024] Embodiment 1: A kind of magnesium oxysulfide wallboard and preparation method thereof, this magnesium oxysulfide wallboard is made up of the raw material of following weight parts: 100 parts of magnesium oxide, 5 parts of modifiers, 130 parts of magnesium sulfate solutions, bamboo fiber 2 parts, 3 parts of brown silk, 30 parts of filler, 1 part of foaming agent, the mass fraction of the magnesium sulfate solution is 30%, and the magnesium oxide is lightly burned magnesite powder (hereinafter referred to as MgO).
[0025] Bamboo fiber has the characteristics of good toughness and high strength, and brown silk has the characteristics of low water absorption, easy dispersion and uniform distribution in random directions. The combination of the two as a reinforcing material can enhance the flexural strength of the product and the uniformity of its strength.
[0026] The modifying agent is polycarboxylic acid, sodium pyrophosphate and polyvinyl alcohol.
[0027] After mixing...
Embodiment 2
[0036] Embodiment 2: A kind of magnesium oxysulfide wallboard and preparation method thereof, this magnesium oxysulfide wallboard is made up of the raw material of following weight part: 100 parts of magnesium oxide, 0.5 part of modifier, 100 parts of magnesium sulfate solution, bamboo fiber 2 parts, brown silk 3 parts, filler 10 parts, foaming agent 1 part. The mass fraction of the magnesium sulfate solution is 24%.
[0037] The modifying agent is polycarboxylic acid, polyvinyl alcohol and aluminum oxide.
[0038] The effect and effect of adding polycarboxylic acid and polyvinyl alcohol are identical with embodiment one.
[0039] After adding alumina, aluminum gel and aluminosilicate are formed in the slurry, which block the capillary channels inside the plate product and improve the structure of the material.
[0040] The filler is mineral powder, silica fume and wood floor sawdust. The effect and advantage of adding slag powder are the same as in embodiment one; silica f...

Abstract
The invention relates to a magnesium oxysulfate wall plate and a fabrication method of the magnesium oxysulfate wall plate. The magnesium oxysulfate wall plate comprises the following raw materials in parts by weight: 100 parts of magnesium oxide, 0.5-5 parts of a modifier, 100-130 parts of a magnesium sulfate solution, 2 parts of bamboo fiber, 3 parts of palm fiber, 10-30 parts of a filling and 1 part of a foaming agent. The fabrication method of the magnesium oxysulfate wall plate comprises the steps of putting the modifier into the magnesium sulfate solution, injecting into an agitator after agitation, putting the bamboo fiber and the palm fiber into the agitator for agitation, putting magnesium oxide in the agitator for agitation, allowing slurry agitated by the agitator to fall into a foam mixing machine, injecting the foaming agent subjected high-pressure foaming into the slurry, performing foam mixing to form uniform foaming slurry, injecting the foaming slurry into a special mold car via a distribution system, and performing foam expelling, fiber stroking, curing, female groove forming, core pulling and push plate mold stripping. The magnesium oxysulfate wall plate is high in structural strength, good in water resistance and stable in physical property.
Description
technical field [0001] The invention relates to a wallboard and a preparation method thereof, in particular to a magnesium oxysulfide wallboard and a preparation method thereof. Background technique [0002] At present, in the light-weight wallboard manufacturing industry that uses magnesium oxide as the cementitious material, magnesium chloride is usually used as a coagulant to make light-weight wallboards, which are referred to as magnesium oxychloride light-weight wallboards in the industry. Wall panels have the advantages of light weight, fire prevention, fast condensation, sound insulation, and heat insulation. However, the magnesium oxychloride light wallboard also has strong corrosion to metal materials, and is prone to moisture absorption and halogen return. [0003] There are also manufacturers trying to produce magnesium oxysulfate light wallboards. Magnesium oxysulfate light wallboards are light wallboards made of magnesium oxide as a cementitious material and ma...
