Cold-resistant high-water-retention wet-mixed mortar plastic stabilizer and preparation method thereof
The invention discloses a cold-resistant high-water-retention wet-mixed mortar plastic stabilizer and a preparation method thereof, and belongs to the technical field of building material additives. The plastic stabilizer is prepared from the following raw materials in percentage by weight: 15-25% of a water reducing agent, 8-15% of an early strength agent, 4-10% of a retarder, 1-5% of a water-retaining self-made auxiliary agent, 0.1-0.3% of an anti-freezing agent, 0.1-0.6% of sodium dodecyl benzene sulfonate and the balance of water. According to the invention, the water reducing agent, the retarder, the air entraining agent, the early strength agent and other components are selected and proportioned properly; the water retention aid is prepared from a natural polymer material namely sodium alginate, the water retention aid and the anti-freezing agent have a synergistic effect, the efficient plastic stabilization effect of the wet-mixed mortar plastic stabilizer is jointly achieved, and the obtained wet-mixed mortar is low in mixing amount, high in water retention rate, high in strength, long in plastic retention time, good in workability, simple in preparation method and wide inmarket application prospect.
本发明公开一种抗寒高保水湿拌砂浆稳塑剂及其制备方法，属于建筑材料外加剂技术领域。本发明稳塑剂是由以下百分含量的原料制备得到：减水剂15‑25％、早强剂8‑15％、缓凝剂4‑10％、保水自制助剂1‑5％、防冻剂0.1‑0.3％、十二烷基苯磺酸钠0.1‑0.6％，余量为水。本发明通过选择和配比合适的减水剂、缓凝剂、引气剂、早强剂等成分，使用天然高分子材料海藻酸钠制备得到保水助剂，其和防冻剂两者协同作用，共同实现了本发明湿拌砂浆稳塑剂高效的稳塑效果，所得湿拌砂浆掺量低、保水率高、强度高，保塑时间长，和易性好，且制备方简单，具有广阔的市场应用前景。
