Retarder for lightweight gypsum and preparation method thereof
The invention discloses a retarder for lightweight gypsum and a preparation method thereof. The retarder for the light gypsum comprises the following raw materials in parts by weight: 300-350 parts of a protein component raw material, 50-150 parts of a pure amino acid raw material, 10-30 parts of a pH value regulator, 20-60 parts of an organic acid, an acid tincture or an ester raw material, 0.1-0.5 part of an odor regulator, 2-8 parts of a reaction catalyst and 350-650 parts of water, the protein component raw material is dissolved in the water, and the mixture is stirred uniformly to obtain the retarder for the light gypsum. The preparation method comprises the following steps: adding a part of a pH value regulator, carrying out a hydrolysis reaction, sequentially adding a pure amino acid raw material, an organic acid, an acid tincture or ester raw material and a reaction catalyst, adjusting the pH value to 7-8, carrying out a heating reaction to obtain a mixture, adding an odor regulator, cooling, and uniformly stirring to obtain the retarder for light gypsum. Through the mode, the retarder for the light gypsum and the preparation method of the retarder have the advantages that the retarding effect is good, the strength loss is small, the influence on the foaming efficiency of foamed gypsum is reduced, and the gypsum setting time is convenient to adjust.
本发明公开了一种轻质石膏用缓凝剂及其制备方法，轻质石膏用缓凝剂包括以下重量份的原料：300~350重量份的蛋白组分原料、50~150重量份的纯氨基酸原料、10~30重量份的pH值调节剂、20~60重量份的有机酸、酸酊或酯类原料、0.1~0.5重量份的气味调节剂、2~8重量份的反应催化剂以及350~650重量份的水，将蛋白组分原料溶解于水中，加入部分pH值调节剂，进行水解反应，依次加入纯氨基酸原料、有机酸、酸酊或酯类原料、反应催化剂，调节pH值至7~8，加热反应，得到混合料，加入气味调节剂，冷却并搅拌均匀，得到轻质石膏用缓凝剂。通过上述方式，本发明所述的轻质石膏用缓凝剂及其制备方法，缓凝效果好，强度损失小，减少了对发泡石膏的发泡效率影响，方便石膏凝结时间的调节。
