The invention relates to a foaming thermal insulation mortar material. The material comprises the following raw materials: cement, sand, slag, gypsum, a water reducing agent, a foaming agent, a foam stabilizer and water. The foaming agent is composed of tea saponin and sodium lauroyl sarcosinate, the mass ratio of the tea saponin to the sodium lauroyl sarcosinate is 1:(0.5-1), and the mass ratio of the foaming agent to the foam stabilizer is 1:(0.2-0.4). The chitosan and the tetradecyl dimethyl tertiary amine are grafted, so that the chitosan has better hydrophilicity and better water solubility; so that the liquid film can be prevented from discharging liquid, the viscosity of a liquid phase can be improved, a high-strength bubble film can be formed, and the molecular structure of an active matter in the bubble film is tighter, so that the foam has higher deformation resistance and high elasticity, and the retention of moisture in the film and the prevention of gas leakage in the bubble are facilitated.
一种发泡保温砂浆材料，包括以下原料：水泥，砂，矿渣，石膏，减水剂，发泡剂，稳泡剂和水，所述发泡剂由茶皂素和月桂酰基肌氨酸钠组成，茶皂素和月桂酰基肌氨酸钠质量比为1:0.5‑1，所述发泡剂与稳泡剂质量比为1:0.2‑0.4，本发明壳聚糖与十四烷基二甲基叔胺进行接枝，使壳聚糖具有更好的亲水性，具备更好的水溶性；可以阻止液膜排液，提高液相黏度，并且能够形成高强度的气泡膜，使气泡膜内活性物分子结构更加紧密，从而使泡沫具有较强的抗变形性能和富有弹性，且有利于膜内水分的保持和阻碍气泡内气体渗漏。
