Mortar composite material for repairing historic building, and preparation method thereof
The invention relates to the technical field of building materials, in particular to a mortar composite material for repairing ancient buildings and a preparation method of the mortar composite material. The mortar composite material is characterized in that an epoxy resin composition is added into an inorganic cementing material composition containing natural hydraulic lime, wherein the epoxy resin as an organic material for buildings has many excellent characteristics such as high adhesion and high toughness in the repair work of ancient buildings; the organic material and the inorganic material are combined, so that the brittle fracture resistance of the prepared mortar is improved by utilizing the high toughness effect of the epoxy resin; and the characteristic of poor durability of the epoxy resin is made up by high durability of the natural hydraulic lime, and the problem of insufficient adhesion of the natural hydraulic lime is made up by high adhesion of the epoxy resin, so that the advantages of the two materials are complementary, the adhesion and toughness of the mortar are improved, and after the mortar is subjected to high temperature, water soaking and long-time illumination, the bonding strength of the interface is still higher than 1.5 MPa.
本发明涉及建筑用材料技术领域，尤其涉及一种古建筑修复用砂浆复合材料及其制备方法。本发明通过在具有天然水硬性石灰的无机胶凝材料组合物中添加环氧树脂组合物，环氧树脂作为建筑用有机材料，在古建筑的修复工作中具备很多优良特性，如高粘接性和高韧性，本发明将有机材料与无机材料结合，一方面，利用环氧树脂的高韧性作用使得制备出的砂浆抵抗脆性断裂的能力提高；另一方面，以天然水硬性石灰的高耐久性弥补环氧树脂耐久性差的特点，而以环氧树脂高粘接性弥补天然水硬性石灰粘接性不足的问题，从而使得双方优势互补，既提高了砂浆的粘接性和韧性，又使得砂浆在经过高温、水浸泡以及长时间的光照作用后，界面的粘接强度仍然高于1.5MPa。
