Preparation method of modified protein gypsum retarder
The invention relates to a preparation method of a modified protein gypsum retarder, which belongs to the field of gypsum building materials, and is characterized by comprising the following steps: hydrolyzing protein powder serving as a raw material into a hydrolyzed protein product; then carrying out graft modification with polysuccinimide, and finally neutralizing; the gypsum retarder prepared by adopting the method has a full-degradation characteristic, meanwhile, the retarding effect is good, and the mixing amount of the required retarder can be greatly reduced.
本发明涉及一种改性蛋白类石膏缓凝剂的制备方法,属于石膏建材领域,其特征在于,包括以下步骤:以蛋白粉为原料,将其水解成水解蛋白产物;然后与聚琥珀酰亚胺进行接枝改性,最后中和;采用本方法制得的石膏缓凝剂具备全降解特性,同时缓凝效果好,能够大大降低所需缓凝剂的掺量。
