Alkali-free chloride-free powdery master batch soluble accelerator as well as preparation method and use method thereof
The invention discloses an alkali-free chloride-free powdery master batch soluble accelerator as well as a preparation method and a use method thereof, and belongs to the technical field of building material admixtures. According to the invention, sulfate and a fluorine-aluminum compound are used as base materials, and the water-based cutting fluid specifically comprises 45-60 wt.% of the base materials, 5-10 wt.% of a stabilizer, 3-5 wt.% of polycarboxylic acid, 5-10 wt.% of lignosulfonate, 1-1.5 wt.% of a pH regulator, 5-8 wt.% of an antifoaming agent, 10-12 wt.% of calcium formate and the balance of water. The preparation method comprises the following steps: pretreating the base material, dissolving and mixing, feeding, adjusting the pH value, decolorizing, concentrating and drying. The prepared accelerator has an efficient coagulation accelerating effect, good crack resistance and impermeability, is environmentally friendly and efficient, and can be widely applied to various cement-based materials; the liquid setting accelerator can be prepared by adding water to dissolve the powdery master batch, and is applied to tunnel spraying construction, so that a powerful guarantee is provided for the safety and stability of a tunnel.
本发明公开了一种无碱无氯粉状母料可溶速凝剂、制备方法及其使用方法，属于建筑材料外加剂技术领域。本发明以硫酸盐和氟铝化合物为基料，具体包括：基料45‑60wt.％，稳定剂5‑10wt.％，聚羧酸3‑5wt.％，木质素磺酸盐5‑10wt.％，pH调节剂1‑1.5wt.％，消泡剂5‑8wt.％，甲酸钙10‑12wt.％，余量为水。制备过程为基料预处理、溶解混合、加料、调节pH值、脱色处理、浓缩干燥。本发明制备所得的速凝剂具有高效促凝作用，良好的抗裂性、抗渗性，环保高效，可广泛应用于各类水泥基材料中；粉状母料加水溶解可制得液体速凝剂应用于隧道喷射的施工，为隧道的安全与稳定提供有力保障。
