Novel aluminum powder foaming agent for autoclaved aerated concrete
The invention discloses a novel aluminum powder foaming agent for autoclaved aerated concrete. The novel aluminum powder foaming agent comprises aluminum powder, a surfactant, a bubble stabilizer, wax and triethanolamine, the mass ratio of the aluminum powder to the surfactant to the bubble stabilizer to the wax to the triethanolamine is (50-60): (15-20): (3-7): (2-4): (4-8); the aluminum powder comprises the following components in percentage by mass: 15 to 25 percent of aluminum powder with the particle size of 10 to 30 microns, 40 to 60 percent of aluminum powder with the particle size of 200 to 300 microns and 25 to 35 percent of aluminum powder with the particle size of 500 to 600 microns. The anti-freezing performance, the heat dissipation performance and the strength of the concrete are effectively improved by adding the aluminum powder with different particle sizes and the corresponding surfactant, the bubble stabilizer and the like.
本发明公开了一种蒸压加气混凝土用新型铝粉发泡剂，包括铝粉、表面活性剂、气泡稳定剂、蜡和三乙醇胺；铝粉、表面活性剂、气泡稳定剂、蜡和三乙醇胺的质量比为50‑60：15‑20:3‑7：2‑4:4‑8；所述铝粉中以质量百分比计，包括15‑25％径粒为10‑30μm的铝粉、40％‑60％径粒为200～300μm的铝粉、25％‑35％径粒为500‑600微米的铝粉。本发明通过添加不同径粒的铝粉以及对应的表面活性剂、气泡稳定剂等，有效提高了混凝土的抗冻性能、散热性能和强度。
