Low-carbon foam concrete composite foaming agent and preparation method thereof
The invention belongs to the field of low-carbon environment-friendly materials, and particularly relates to a low-carbon foam concrete composite foaming agent and a preparation method thereof. The invention relates to a low-carbon foam concrete composite foaming agent, which comprises the following components in percentage by mass: 10% of hydrolyzed protein with gelatin powder as a base material; the alkaline protease is selected from papain, and the mass fraction is 2.1%; the surface active substance is fatty ether polyoxyethylene alcohol sodium sulfate, and the mass fraction is 1-2%; sodium caseinate with a mass fraction of 8-9%; deionized water is selected as water for dissolving and accounts for the rest mass fraction. Compared with the existing foaming agent for foam concrete, the low-carbon foam concrete composite foaming agent provided by the invention avoids the problems of high cost, toxicity to operators and the like of the existing foaming agent; other organic solvents with dangerous properties do not need to be doped, only physical change occurs in the whole preparation process, no harmful gas is emitted, and no danger is caused by the fact that a solid powdery foaming agent is inhaled into a human body; the method has the advantages of fewer operation steps, reasonable process optimization, easiness in large-scale industrial production, and realization of the targets of low carbon and environmental protection.
本发明属于低碳环保材料领域，具体地，涉及一种低碳泡沫混凝土复合发泡剂及其制备方法。低碳泡沫混凝土复合发泡剂，配方组份如下：选用吉利丁粉为基料水解蛋白质，质量分数为10％；碱性蛋白酶选用木瓜蛋白酶，质量分数为2.1％；表面活性物质为脂肪醚聚氧乙烯醇硫酸钠，质量分数为1‑2％；酪蛋白酸钠，质量分数为8‑9％；溶解用水选用去离子水，占剩余质量分数。与现有的泡沫混凝土用发泡剂相比，本发明的低碳泡沫混凝土复合发泡剂避免了现有的发泡剂存在的高成本、对操作者的毒性等问题；不需掺加其它有危险性质的有机溶剂，且制备全程只发生物理变化，无有害气体放出，无固体粉质发泡剂吸入人体所带来的危险；操作步骤较少、过程优化合理、易用于大规模工业生产，实现低碳环保的目标。
