Novel gypsum retarder and preparation method thereof
The invention discloses a novel gypsum retarder and a preparation method thereof, and the novel gypsum retarder comprises the following components in parts by weight: 200-500 parts of a protein raw material, 200-700 parts of an acidic substance, 10-100 parts of an alkaline substance, 2-100 parts of protease, 50-200 parts of an acyl halide synthetic raw material and water. The content of the water is 300 to 500 parts. The obtained novel gypsum retarder is high in effective product yield, can exert an excellent retarding effect at an extremely low mixing amount, and is better in adaptability to industrial byproduct gypsum.
本发明公开了一种新型石膏缓凝剂及其制备方法，包括蛋白质原料、酸性物质、碱性物质、蛋白酶、酰卤合成原料和水，各成分按重量份计为：所述蛋白质原料200‑500份，所述酸性物质200‑700份，所述碱性物质10‑100份，所述蛋白酶2‑100份，所述酰卤合成原料50‑200份，所述水300‑500份。本发明所得新型石膏缓凝剂有效产物收率高，在极低掺量就能发挥极佳缓凝效果，对工业副产石膏适应性更好。
