Composition for alkali-free liquid accelerator, alkali-free liquid accelerator as well as preparation method and application of alkali-free liquid accelerator
The invention relates to the technical field of building materials, and discloses a composition for an alkali-free liquid accelerator, the alkali-free liquid accelerator as well as a preparation method and application of the alkali-free liquid accelerator. On the basis of the total weight of the composition, the composition is prepared from 53 wt%-56 wt% of aluminum sulfate octadecahydrate, 5 wt%-6.5 wt% of diethanol amine, 3 wt%-6 wt% of silane emulsion, 0.8 wt%-2 wt% of amino acid, 0.8 wt%-1.5 wt% of kaolinite, 0.7 wt%-1.2 wt% of a pH regulator and 30 wt%-35 wt% of water. The purity of the kaolinite is greater than or equal to 90wt%; the silane emulsion is an octyltriethoxysilane emulsion and/or a tetraethoxysilane emulsion, and the silane emulsion is an octyltriethoxysilane emulsion and/or a tetraethoxysilane emulsion; the amino acid is lysine and/or threonine. The alkali-free liquid accelerator provided by the invention is better in stability and more excellent in early-strength coagulation accelerating, seepage-proofing and hydrophobic properties.
本发明涉及建筑材料技术领域，公开了一种无碱液体速凝剂用组合物、无碱液体速凝剂及其制备方法和应用。以所述组合物的总重量为基准，所述组合物中含有：十八水硫酸铝53‑56wt％，二乙醇胺5‑6.5wt％，硅烷乳液3‑6wt％，氨基酸0.8‑2wt％，高岭石0.8‑1.5wt％，pH调节剂0.7‑1.2wt％，水30‑35wt％；所述高岭石的纯度≥90wt％；所述硅烷乳液为辛基三乙氧基硅烷乳液和/或四乙氧基硅烷乳液；所述氨基酸为赖氨酸和/或苏氨酸。本发明提供的无碱液体速凝剂稳定性更好，并且早强促凝和防渗憎水性能更优异。
