Magnesium oxysulfate wall plate and fabrication method thereof

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...

AI Technical Summary

Problems solved by technology

Some factories without technological conditions and modification technology produce magnesium oxysulfide lightweight wallboards, which limit their popularization and application because their strength is much lower than that of magnesium oxychloride light wallboards.
