Backfill foaming agent as well as preparation method and application thereof
The invention provides a backfill foaming agent and a preparation method and application thereof, and the preparation method comprises the following steps: (1) adding 69.2-79.6 parts by mass of water into a dispersion machine, then adding 0.2-0.4 part by mass of cellulose ether, 0.2-0.4 part by mass of a thickening agent and 20-30 parts by mass of a surfactant, stirring for 10-20 minutes, and stopping stirring when the water temperature is reduced to 35 DEG C or below to prepare a foaming agent component A; (2) adding 13.6-33.8 parts by mass of water into a dispersion machine, then adding 3-6 parts by mass of a foam stabilizer, stirring for 5-10 minutes, adding 0.2-0.4 part by mass of a bactericide, adding 70-80 parts by mass of a foaming agent component A, adding 7-9 parts by mass of modified composite particles, and continuously stirring for 10-20 minutes; the backfilling foaming agent is obtained. The backfill foaming agent improves the volume stability of foam concrete and solves the problems of shrinkage and collapse of the foam concrete.
本发明提供了一种回填发泡剂及其制备方法和应用，包括以下步骤：(1)按质量份数计，将69.2‑79.6份水加入分散机中，然后加入0.2‑0.4份纤维素醚，加入0.2‑0.4份增稠剂，加入20‑30份表面活性剂，搅拌10‑20min，当水温降至35℃以下停止搅拌，制得发泡剂组分A；(2)按质量份数计，将13.6‑33.8份水加入分散机中，然后加入3‑6份稳泡剂，搅拌5‑10min，加入0.2‑0.4份杀菌剂，加入70‑80份发泡剂组分A，加入7‑9份改性复合粒子，继续搅拌10‑20min；得到回填发泡剂。本发明的回填发泡剂提高了泡沫混凝土的体积稳定性，解决泡沫混凝土的收缩和塌陷问题。
