Foaming agent for phosphogypsum as well as preparation method and application of foaming agent
The invention belongs to the technical field of foaming agents, and provides a foaming agent for phosphogypsum and a preparation method and application thereof. Sodium dodecyl benzene sulfonate and sodium dodecyl sulfate are added into the foaming agent for ardealite, so that the foaming agent has good compatibility with ardealite, and the performance of foam can be well maintained. Meanwhile, the sodium dodecyl benzene sulfonate, the sodium dodecyl sulfate, the coconut oil amide propyl amine oxide, the sodium alpha-olefin sulfonate and the lauryl sodium sulfate are added, so that the surface tension of the foaming liquid can be reduced, and the foamability can be enhanced. Besides, the protein foaming agent is added, so that surface active molecules adsorbed on the foam film are increased, the foam film is more compact, gas in foam is difficult to diffuse outwards through a liquid film, and the foam stability is enhanced; moreover, the addition of the foam stabilizer also ensures that the foam has better stability, so that the foaming agent for phosphogypsum disclosed by the invention can still keep a good foam form under high-speed stirring, and various properties of the prepared phosphogypsum block can be greatly improved.
本发明属于发泡剂技术领域，提供了一种磷石膏用发泡剂及其制备方法和应用。本发明在磷石膏用发泡剂中加入十二烷基苯磺酸钠和十二烷基磺酸钠，使得该发泡剂对磷石膏相性好，可以良好地维持泡沫的性能。同时，十二烷基苯磺酸钠、十二烷基磺酸钠、椰子油酰胺丙基氧化胺、α‑烯基磺酸钠和十二烷基硫酸钠的加入可以使发泡液的表面张力降低，增强起泡性。另外，蛋白发泡剂的加入，使得泡膜上吸附的表面活性分子增多，泡膜更加致密，泡沫内气体难以通过液膜向外扩散，增强了泡沫稳定性；而且，稳泡剂的加入也保证了泡沫具有更好的稳定性，使得本发明的磷石膏用发泡剂在高速搅拌下仍能保持良好的泡沫形态，可以大大提高制得的磷石膏砌块的各项性能。
