Calcium sulfate retarder and preparation method thereof
The invention relates to the field of gypsum building materials, and discloses a calcium sulfate retarder. The calcium sulfate retarder is prepared from the following components in percentage by mass: 20-30 percent of a protein component raw material, 3-5 percent of an alkaline substance, 7.5-15 percent of sodium dihydrogen phosphate, 3.75-7.5 percent of organic acid, anhydride or ester, 0.01-0.05 percent of phenethyl acetate, 0.05-0.1 percent of sodium benzoate, 0.2-0.8 percent of diisopropylethylamine and 50-65 percent of water. The invention further discloses a method for preparing the calcium sulfate retarder. The calcium sulfate retarder is used for regulating the coagulation of building gypsum, and has the characteristics of low cost, good delayed coagulation effect and small strength loss.
