Low-temperature foaming agent for foamed light soil
The invention discloses a low-temperature foaming agent for foamed light soil, which comprises the following components in parts by weight: 30-50 parts of modified alpha-alkenyl sodium sulfonate, 10-30 parts of dodecyl methyl benzyl ammonium chloride, 5-20 parts of polyethyleneimine, 1-5 parts of a foam stabilizer, 1-3 parts of an anti-caking agent, 10-15 parts of a solvent and 0.5-1 part of an acid substance. Alpha-alkenyl sodium sulfonate is modified, so that the foaming agent has a relatively high foaming rate, the low-temperature water solubility of the foaming agent is enhanced, and the salt and alkali resistance of the foaming agent is greatly improved. And the modified alpha-alkenyl sodium sulfonate and dodecyl methyl benzyl ammonium chloride are adopted to generate a synergistic effect, so that the foam stability is enhanced. Through the synergistic effect of the components in the formula, the foaming agent has high foaming ratio, the generated foam is uniform, fine and smooth,the foam wall is stable, and a bubble group is formed by independent closed bubbles; the foaming agent has good stability in cement paste or slurry, and the hardened foamed light soil has the characteristics of uniform honeycomb pores, independence, no large bubbles, suitability for low-temperature environment and the like.
本发明公开了一种泡沫轻质土用低温发泡剂，按重量份计，包括改性α‑烯基磺酸钠30‑50份，十二烷基甲基苄基氯化铵10‑30份，聚乙烯亚胺5‑20份，稳泡剂1‑5份，抗结剂1‑3份，溶剂10‑15份，酸类物质0.5‑1份。将α‑烯基磺酸钠进行改性，不仅使该发泡剂具有较高的发泡率增强其低温水溶性，还使得其抗盐碱性得到了很大的提升。改性α‑烯基磺酸钠与十二烷基甲基苄基氯化铵产生协同作用，增强了泡沫稳定性。配方组分间的协同作用使得该发泡剂具有发泡倍率高，生成的泡沫均匀细腻、泡壁稳定，由独立密闭气泡形成气泡群；在水泥浆或料浆中稳定性好，硬化后的泡沫轻质土的蜂窝孔隙均匀、独立，无大气泡，适用于低温环境等特点。
