Self-dispersing nano silicon dioxide particle for cement-based material and preparation method of self-dispersing nano silicon dioxide particle
The invention belongs to the technical field of building materials, and particularly relates to self-dispersing nano silicon dioxide particles for a cement-based material and a preparation method of the self-dispersing nano silicon dioxide particles. The preparation method of the self-dispersing nano silicon dioxide particles for the cement-based material in the embodiment comprises the following steps: (1) mixing alkyl silane and water, stirring and heating; (2) after the temperature is increased to 80 DEG C or above, adding nano silicon dioxide and continuously stirring; and (3) after the stirring is finished, carrying out solid-liquid separation, and drying to obtain the self-dispersed nano silicon dioxide particles for the cement-based material. The self-dispersing nano silicon dioxide particles for the cement-based material are beneficial to solving or relieving the problems that in the prior art, when nano silicon dioxide is applied to the cement-based material, agglomeration is prone to occurring, and dispersity is poor.
本发明属于建筑材料技术领域，具体涉及一种用于水泥基材料的自分散纳米二氧化硅颗粒及其制备方法。本实施例的用于水泥基材料的自分散纳米二氧化硅颗粒的制备方法，包括下述步骤：(1)将烷基硅烷与水混合搅拌并加热；(2)待温度加热至80℃以上，加入纳米二氧化硅并继续搅拌；(3)搅拌结束后，固液分离，干燥，即得所述用于水泥基材料的自分散纳米二氧化硅颗粒。本发明的用于水泥基材料的自分散纳米二氧化硅颗粒有助于解决或缓解现有技术中纳米二氧化硅应用于水泥基材料时，容易团聚、分散性差的问题。
