Inorganic water-based permeable sand consolidation agent and preparation method thereof
The invention discloses an inorganic water-based permeable sand consolidation agent and a preparation method thereof. The inorganic water-based permeable sand consolidation agent is prepared from, byweight, 40-50 parts of a sodium silicate solution, 2-5 parts of a curing agent, 0.05-0.25 part of a surfactant, 0.8-2 part of a surface hardening agent and 40-50 parts of deionized water. Sodium silicate is used as a main component, a sand layer can be solidified by utilizing a self solidification reaction, and stable silica gel is generated through a synergistic effect formed by compounding witha curing agent so that sodium silicate forms a layer of compact silica gel film on a concrete base surface to achieve the purpose of sand solidification, and meanwhile, a dispersion effect can be achieved, agglomeration of sodium silicate colloidal particles can be effectively hindered, the sodium silicate is kept in a nanoscale size and permeation in concrete is facilitated.
本发明公开了一种无机水性渗透型固砂剂及其制备方法，其中无机水性渗透型固砂剂，按重量份数包括硅酸钠溶液40‑50份、固化剂2‑5份、表面活性剂0.05‑0.25份、表面硬化剂0.8‑2份、去离子水40‑50份，本发明以硅酸钠作为主要成分，可利用自身的固化反应固结砂层，通过与固化剂的复配形成协同增效作用，生成稳定的硅胶，使硅酸钠在混凝土基面上形成一层致密的硅胶薄膜，以达到固砂的目的，同时还能起到分散的作用，可有效阻碍硅酸钠胶体粒子的团聚，使得硅酸钠保持以纳米级的尺寸，有利于在混凝土中的渗透。
