The invention discloses a self-repairing protein-based cement foaming agent which comprises the following raw materials: a protein stock solution, sodium dithionite, zinc oxide, calcium chloride, sodium chloride, a stabilizer, a chelating agent, hexanediol and a preservative. The protein-based cement foaming agent is simple to prepare and high in compatibility with cement, foam can be self-repaired in the foam mixing operation process, less defoaming or even no defoaming can be achieved in cement slurry, the foam is stable, most of the foam in prepared foam concrete is of a more stable closed-cell structure. The prepared foam concrete product is light in weight and more excellent in mechanical property (especially compressive strength), thermal property and the like, and the compressive strength of the light foam concrete product with the volume weight of 500 kg/m<3> can reach 4-8 MPa.
本发明公开一种自修复蛋白基水泥发泡剂，其包括以下原料：蛋白原液、连二亚硫酸钠、氧化锌、氯化钙、氯化钠、稳定剂、螯合剂、己二醇、防腐剂。本发明的蛋白基的水泥发泡剂制备简单、与水泥的相容性强，且其在混泡操作过程中能够对泡沫进行自修复，在水泥浆料中能够达到少消泡甚至不消泡，泡沫稳定，其在制备的泡沫混凝土中的泡沫大多数为更为稳定的闭孔结构，所制备的泡沫混凝土制品的轻质、力学性能(尤以抗压强度)、热学性能等更为优异，其可使容重500kg/m3的轻质泡沫混凝土制品的抗压强度达到4‑8MPa。
