Fibrous inorganic toughening composite material and preparation method thereof
The invention belongs to the technical field of building material additives, and particularly discloses a fibrous inorganic toughening composite material for enhancing the toughness of a cement-based material and a preparation method of the fibrous inorganic toughening composite material. The fibrous inorganic toughening composite material provided by the invention is a polycrystalline material composed of calcium silicate fiber, calcium oxide, silicon dioxide and metal oxide, wherein the calcium oxide, the silicon dioxide and the metal oxide are attached to the surface of the calcium silicate fiber. The main component of the fibrous inorganic toughened composite material is calcium silicate substances, an internal toughening mechanism is shown by inducing a hydration product through chemical components, the fibrous morphology of the fibrous inorganic toughened composite material exists in the cement hydration product in a rivet form, an external toughening mechanism is shown, and crack resistance of a cement-based material is achieved. The fibrous inorganic toughening composite material 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，尤其公开了一种用于水泥基材料韧性增强的纤维状无机增韧复合材料、及其制备方法。本发明提供的纤维状无机增韧复合材料，是由硅酸钙纤维以及附着在该硅酸钙纤维表面上的氧化钙、二氧化硅、及金属氧化物构成的多晶材料。该纤维状无机增韧复合材料，主要成分为硅酸钙类物质，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。该纤维状无机增韧复合材料，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。
