Hazardous chemical substance-free magnesium-aluminum fluoride system alkali-free setting accelerator without hazardous chemical substances and preparation method thereof
The invention provides a hazardous chemical substance-free magnesium-aluminum fluoride system alkali-free accelerator which comprises the following components in parts by weight: 40-55 parts of aluminum sulfate, 0-15 parts of magnesium sulfate, 3-8 parts of magnesium fluosilicate, 0.5-1.5 parts of magnesium hydroxide, 0-8 parts of cryolite, 1-14 parts of amine compounds and 20-30 parts of water. According to the hazardous chemical substance-free magnesium-aluminum fluoride system alkali-free setting accelerator provided by the invention, the reaction system reaction can achieve the dissolutionreaction, and the prepared accelerator does not contain hydrofluoric acid and fluosilicic acid, so that harmful gas cannot be generated during the construction process, the influence of the harmful gas on the health of the construction personnel is avoided, the pollution of the harmful gas on the air is avoided, and the safety and the environmental protection are provided.
本发明提供一种无危化品的氟化镁铝体系无碱速凝剂，包括以下组分，按重量份计算，硫酸铝40～55份、硫酸镁0～15份、氟硅酸镁3～8份、氢氧化镁0.5～1.5份、冰晶石0～8份、胺类化合物1～14份和水20～30份。本发明所提供的无危化品的氟化镁铝体系无碱速凝剂，反应体系反应能够溶解反应，制得的速凝剂不含有氢氟酸和氟硅酸，因此在施工过程中，不会产生有害气体，避免了有害气体对施工人员健康的影响，以及避免了有害气体对空气的污染，因此更加安全、环保。
