High-strength repairing material for highway bridge expansion joints and preparation method of high-strength repairing material
The invention belongs to the technical field of road engineering, and particularly relates to a high-strength repairing material for a highway bridge expansion joint and a preparation method. The coating comprises the following components in parts by weight: 100 parts of epoxy resin, 20-40 parts of cement, 30-50 parts of fly ash, 10-30 parts of silicon powder, 15-25 parts of a carbon material, 10-20 parts of alumina fiber coated POSS (Polyhedral Oligomeric Silsesquioxane), 5-15 parts of a plasticizer, 5-15 parts of a diluent and 3-7 parts of a curing agent. By adding the carbon material and the alumina fiber coated POSS, the mechanical property and strength of the repairing material can be enhanced, the durability of the repairing material is enhanced, and the repairing material has a good application prospect.
本发明属于道路工程技术领域，具体涉及一种用于公路桥梁伸缩缝的高强度修补材料和制备方法。按重量份计，包括以下组分：环氧树脂100份，水泥20～40份，粉煤灰30～50份，硅粉10～30份，碳材料15～25份，氧化铝纤维@POSS 10～20份，增塑剂5～15份，稀释剂5～15份，固化剂3～7份。本发明通过添加碳材料和氧化铝纤维@POSS，能够增强修补材料的力学性能和强度，增强修补材料的耐久性，具有很好的应用前景。
