CHENG JIANCHUN / CHENG XINGQIANG / GAO CHUANJIE

The invention discloses an inorganic salt alkali efflorescence prevention accelerator which comprises the following raw materials in percentage by weight: 30-50% of aluminum sulfate, 20-30% of aluminum nitrate, 10-14% of magnesium sulfate, 5-10% of aluminum lactate, 5-10% of aluminum citrate, 5-7% of alcohol amine, 0.3-0.5% of a thickening agent and 1-2% of a stabilizer. According to the inorganic salt alkali efflorescence prevention accelerator, the raw materials required by the accelerator are reasonably configured, so that the quality problems of building moisture regain and the like during use are well avoided, the structural strength of a building is ensured, and the building quality is guaranteed. Moreover, the preparation method of the inorganic salt alkali efflorescence prevention accelerator has simple steps, provides good preparation and processing conditions, avoids the alkali efflorescence problem occurring after the inorganic salt alkali efflorescence prevention accelerator is used with concrete, reduces exhaust emission, and better protects the environment.

本发明公开了一种无机盐防返碱速凝剂，包含原料配比为：硫酸铝30～50％、硝酸铝20～30％、硫酸镁10～14％、乳酸铝5～10％、柠檬酸铝5～10％、醇胺5～7％、增稠剂0.3～0.5％、稳定剂1～2％。该无机盐防返碱速凝剂合理配置速凝剂所需原料，较好的避免了使用出现的建筑物返潮等质量问题，确保了建筑结构强度，保障了建筑质量。并且，该无机盐防返碱速凝剂制备方法步骤简单，提供良好制备加工条件，避免了与混凝土使用后出现的返碱问题，也减少了废气排放，较好的保护的环境。
