Mortar composite material for repairing masonry ancient building, and preparation method thereof
The invention relates to the technical field of building materials, in particular to a mortar composite material for repairing masonry ancient buildings, and a preparation method of the mortar composite material. According to the invention, an epoxy resin is combined with natural hydraulic lime, wherein the brittle fracture resistance of the prepared mortar is improved by utilizing the high-toughness effect of the epoxy resin, 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 parties are complementary, the adhesion and toughness of the mortar are improved, after the mortar is subjected to high temperature, water soaking and long-time illumination, the bonding strength of an interface is still higher than 1.5 MPa; and by adding a modified amine curing agent, an organic material (epoxy resin) and an inorganic material (natural hydraulic lime) are better compatible to solve the problem of interface layering, so that the overall performance of the mortar composite material is improved.
本发明涉及建筑用材料技术领域，尤其涉及一种砖石古建筑修复用砂浆复合材料及其制备方法。将环氧树脂与天然水硬性石灰结合，一方面，利用环氧树脂的高韧性作用使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；并且，通过添加改性胺类固化剂，使得有机材料(环氧树脂)与无机材料(天然水硬性石灰)更好的相容，解决了界面分层的问题，从而提高砂浆复合材料的整体性能。
