Elastic polyurea mortar and preparation method thereof
The invention belongs to the technical field of concrete crack repairing materials, and particularly relates to elastic polyurea mortar and a preparation method thereof. The elastic polyurea mortar is prepared from the following components in parts by weight: 20 to 25 parts of polyurea, 60 to 85 parts of inorganic filler, 0.5 to 1.5 parts of coupling agent, 0.5 to 1.5 parts of defoaming agent, 3 to 6 parts of diluent and 0.3 to 1.2 parts of anti-aging agent. The elastic polyurea mortar disclosed by the invention has the characteristic that existing mortar can be poured, has relatively high strength after being cured, and also has extensibility and flexibility, the elastic polyurea mortar is deformed under the action of external force, the elastic polyurea mortar recovers an original structure under the action of elasticity after the external force disappears, and the elastic polyurea mortar has the performance advantages of high toughness, high strength and low elastic modulus.
本发明属于混凝土裂缝修复材料技术领域，特别涉及一种弹性聚脲砂浆及其制备方法。一种弹性聚脲砂浆，以重量份计，包括聚脲20‑25份、无机填料60‑85份、偶联剂0.5‑1.5份、消泡剂0.5‑1.5份、稀释剂3‑6份和防老剂0.3‑1.2。本发明弹性聚脲砂浆，具有现有砂浆可浇筑的特性，固化后具有较高的强度，同时还具有延伸性和柔韧性，弹性聚脲砂浆受外力作用产生形变，外力消失后，弹性聚脲砂浆在弹性作用下恢复原始结构，具高韧性、高强度、低弹性模量的性能优点。
