Graphene alkali-free liquid accelerator as well as preparation method and application thereof
The invention provides a graphene alkali-free liquid accelerator as well as a preparation method and application thereof. The graphene alkali-free liquid accelerator comprises an aluminum-containing solution, a few-layer graphene dispersion liquid, a coagulant aid and a pH regulator. The preparation method comprises the following step: mixing the aluminum-containing solution, the few-layer graphene dispersion liquid, the coagulant aid and the pH regulator to obtain the graphene alkali-free liquid accelerator. The graphene alkali-free liquid accelerator is used for spraying concrete. According to the invention, the few-layer graphene dispersion liquid prepared from expanded graphite is used for the graphene alkali-free liquid accelerator, and the graphene alkali-free liquid accelerator which is high in compressive strength, short in initial and final setting time and low in production cost can be obtained without a heating step.
本发明提供了一种石墨烯无碱液体速凝剂及其制备方法和用途，所述石墨烯无碱液体速凝剂包括：含铝溶液、少层石墨烯分散液、助促凝剂和pH调节剂；所述制备方法包括以下步骤：混合含铝溶液、少层石墨烯分散液、助促凝剂和pH调节剂，得到所述石墨烯无碱液体速凝剂，所述石墨烯无碱液体速凝剂用于喷射混凝土；本发明利用膨胀石墨配制少层石墨烯分散液用于石墨烯无碱液体速凝剂，无需加热步骤即可得到抗压强度高、初终凝时间短且生产成本低的石墨烯无碱液体速凝剂。
