Compression-resistant fireproof plaster mortar and preparation method thereof
The invention relates to compression-resistant fireproof plaster mortar which is prepared from the following raw materials in parts by weight: 2-4 parts of stearic acid, 2-4 parts of sodium carboxymethylcellulose, 10-14 parts of magnesium oxide, 70-90 parts of expand perlite powder, 80-100 parts of quartz sand, 2-3 parts of sodium thiosulfate, 3-5 parts of potassium carbonate, 60-70 parts of pumice, a proper amount of water, 20-25 parts of auxiliaries, 150-160 parts of cement, 60-70 parts of steel slag micropowder and 100-130 parts of yellow sand. The mortar provided by the invention is good in compactness, high in compression strength and good in water resistance, further has excellent fireproof performance, and is exquisite in surface, good in durability and good in water resistance as plaster mortar. By using the auxiliaries, the compression strength and breaking strength of the mortar are improved, and the workability, the anti-sagging property, the thixotropy and the anti-sedimentation property are improved.
