Calcium sodium silicate micro-nano fiber toughening agent and preparation method thereof
The invention belongs to the technical field of building material additives, and particularly discloses a preparation method of a sodium calcium silicate micro-nanofiber toughening agent and the sodium calcium silicate micro-nanofiber toughening agent obtained by the preparation method. The calcium sodium silicate micro-nano fiber toughening agent provided by the invention has the main component of calcium sodium silicate, is a sodium-doped calcium silicate substance, and when the calcium sodium silicate micro-nano fiber toughening agent is applied to a cement-based material, a hydration product is induced through chemical components to show an internal toughening mechanism; in addition, the fibrous morphology exists in a cement hydration product in a rivet form, so that an external toughening mechanism is shown, and the crack resistance of the cement-based material is realized. The calcium sodium silicate micro-nano fiber toughening agent is similar to components in a cement-based material and has good compatibility with the components in the cement-based material; all the components are inorganic components and do not contain organic matters, so that adverse effects on cement hydration can be avoided when the components are applied.
本发明属于建筑材料添加剂技术领域，尤其公开了一种硅酸钠钙微纳米纤维增韧剂的制备方法、以及由此获得的硅酸钠钙微纳米纤维增韧剂。本发明提供的该硅酸钠钙微纳米纤维增韧剂，主要成分为硅酸钠钙，是一种钠掺杂的硅酸钙类物质，当其应用至水泥基材料中时，不仅通过化学组分诱导水化产物而展现出内增韧机制，而且其纤维状形貌还以“铆钉”的形式存在于水泥水化产物中，展现出外增韧机制，实现水泥基材料抗裂。该硅酸钠钙微纳米纤维增韧剂，与水泥基材料中组分相似二者具有很好的相容性；且其中均为无机组分，不含有机物，其应用也不会对水泥水化产生不利影响。
