Alkali-free liquid accelerator as well as preparation method and application thereof
The invention discloses an alkali-free liquid accelerator as well as a preparation method and application thereof, and the alkali-free liquid accelerator comprises the following raw material components in parts by mass: 12-18 parts of aluminum alkoxide; 7-13 parts of aluminum nitrate; 25-35 parts of aluminum sulfate; 4-8 parts of alcohol amine; 12-18 parts of fluorine-containing inorganic acid; 10-20 parts of a component A; and 6-12 parts of water, wherein the component A is dimethyl sulfoxide and/or dimethyl formamide. The low-temperature stability of the product can be greatly improved, and the product can be stored at -20 DEG C for a long time.
本发明公开了一种无碱液体速凝剂及其制备方法和应用，按质量份，所述无碱液体速凝剂的原料组分包括：醇铝12‑18份；硝酸铝7‑13份；硫酸铝25‑35份；醇胺4‑8份；含氟无机酸12‑18份；组分A 10‑20份；水6‑12份；其中，所述组分A为二甲基亚砜和/或二甲基甲酰胺。本发明可使产品的低温稳定性大幅增加，能够在‑20℃环境中长期储存。
