摘　　要：采用α烯基磺酸钠（AOS）、十二烷基硫酸钠（SDS）、十二烷基苯磺酸钠（LAS）等阴离子表面活性剂以及硅树脂聚醚乳液（MPS）、十二醇、羟乙基纤维素等稳泡剂,对混凝土用蛋白质发泡剂进行复配改性.结果表明：阴离子表面活性剂的发泡能力远高于蛋白质发泡剂,但泡沫稳定性不及蛋白质发泡剂;掺入适量三类表面活性剂可有效提高蛋白质发泡剂的发泡能力和泡沫的稳定性,合适掺量为0.9-1.0g/L;硅树脂聚醚乳液和十二醇均能较好提高发泡剂的发泡与稳定性能,但两者不宜同时掺加;羟乙基纤维素是一种性能优异的稳泡剂,合适掺量在1.0g/L及以下.using the anionic surfactant and the foam stabilizer to compound modified with Protein-concrete foaming agent.the anionic surfactant includeα-olefin sulfonate(AOS),sodium dodecyl sulfate(SDS),sodium dodecyl benzene sulfonate(LAS),the foam stabilizer include Polyether silicone emulsion(MPS),dodecyl alcohol and hydroxyethyl cellulose.The results show that the foam stability of proteins foaming is much better than the anionic surfactant,however the foam volume is inadequate.The three kinds anionic surfactants can all be used to improve the foam property of Protein-concrete foaming agent,the appropriate dosage is 0.9-1.0g/L.Polyether silicone resin emulsion(MPS)and dodecyl alcohol all can improve the foam property of composite system but they can not be doped together.Hydroxyethyl cellulose is a high performance foam stabilizer,the right dosage at 1.0g/L or less.
