Abstract
The present invention relates to a light magnesium oxychloride building material which mainly uses magnesium oxide and magnesium chloride as base materials. Raw materials of tri-alum waterproof agent water solution, phosphonic acid of 85%, quartz sand, talcum powder, sawdust, etc. are added in the base materials, and are stirred at a room temperature of 20 to 25 DEG C. The building material can be used for water resistance, moisture protection and anti-seepage. The disadvantages of porosity and easy leakage of a magnesium oxychloride material are overcome, and the problem of low strength of a later stage of the magnesium cement products is further solved. The material products have no phenomena of warping deformation and hygroscopicity, the colour is distributed uniformly, and the material products can be sawn and nailed, and has the advantages of high strength, non-toxicity, harmlessness, fire prevention and corrosion prevention. The reaction speed of magnesium oxide and magnesium chloride can be nicely controlled.
Description
The present invention relates to a kind of light magnesium oxychloride building material.
In the prior art, magnesium cement product is because shortcoming such as itself performance of magnesium cement exists the moisture absorption, returns halogen, buckling deformation and later strength are low.
