Fluorine-free anti-freezing liquid alkali-free accelerator and preparation method thereof
The invention discloses a fluoride-free anti-freezing liquid alkali-free accelerator and a preparation method thereof, and belongs to the technical field of building materials. The accelerator is prepared from the following raw materials in parts by weight: 20-40 parts of a macromolecular coagulation accelerator, 25-45 parts of aluminum sulfate, 2-7 parts of magnesium hydroxide, 2-6 parts of alkylol amine, 0.3-1.0 part of a complexing agent, 1-4 parts of an anti-freezing agent and 25-45 parts of water. By using the synthesized macromolecular coagulation accelerator, the overall performance of the accelerator can be greatly improved, the strength is improved, the setting time is shortened, any fluorine-containing raw materials such as hydrofluoric acid and fluosilicate are not used, and the accelerator has no toxic and harmful effects on the ecological environment in the production and use processes. The obtained accelerator has excellent stability and can be normally constructed and applied under the low-temperature condition of -15 DEG C or above.
本发明公开一种无氟防冻型液体无碱速凝剂及其制备方法，属于建筑材料技术领域。本发明速凝剂包括以下重量份的原料制备而成：高分子促凝剂20‑40份、硫酸铝25‑45份、氢氧化镁2‑7份、醇胺2‑6份、络合剂0.3‑1.0份、防冻剂1‑4份、水25‑45份。本发明使用合成的高分子助凝剂，可大幅提升速凝剂的整体性能，提升强度，降低凝结时间，且不使用氢氟酸、氟硅酸盐等任何含氟原料，速凝剂生产和使用过程对生态环境无毒害作用。所得速凝剂稳定性极佳，能够在‑15℃以上低温条件正常施工应用。
