Rapid-curing high-interface bonding strength coating material for cement pavement and preparation method of rapid-curing high-interface bonding strength coating material
The invention relates to a cement pavement rapid curing high interface bonding strength coating material and a preparation method thereof. The material is prepared by mixing a solid component and a liquid component, the solid component is prepared by mixing Portland cement, sulphoaluminate cement, quartz sand, alpha semi-hydrated gypsum, silica fume, silane and rubber powder; the liquid component is prepared by mixing water-borne epoxy resin, a water-borne epoxy curing agent and water. The coating material has the advantages that the coating material can be cured within 30 min to form a coating, the interface bonding strength reaches 0.8 MPa after curing is conducted for 3 h, the interface bonding strength reaches 1 MPa after curing is conducted for 24 h, and therefore it is ensured that a repairing layer and old concrete are tightly combined, and the repairing layer is effectively prevented from falling off. Construction is convenient and efficient, and the repairing efficiency can be improved by 10-20 times. The coating has good freeze-thaw resistance, and the durability of the coating can be prolonged.
一种水泥道面快速固化高界面粘结强度涂层材料及制备方法。材料由固态组分和液态组份混合而制成；固态组分由硅酸盐水泥、硫铝酸盐水泥、石英砂、α半水石膏、硅灰、硅烷和胶粉混合而制成；液态组分由水性环氧树脂、水性环氧固化剂和水混合而制成。本发明效果：本涂层材料可在30min内固化而形成涂层，固化3小时的界面粘结强度达到0.8MPa，24h界面粘结强度达1MPa，从而确保了修复层与旧混凝土之间的紧密结合，有效防止了修复层脱落。施工便捷高效，修复效率可提升10‑20倍。涂层具有较好的抗冻融性能，有助于延长涂层的耐久性。
