Quick-acting repair strip for road and bridge cracks
The invention provides a quick-acting repair strip for road and bridge cracks, and relates to the technical field of road and bridge crack reinforcement. The quick-acting repair strip for the road and bridge cracks comprises a curing raw material group, a repair raw material group and a stable raw material group, and the repair raw material group comprises the following raw materials in parts by weight: 30-40 parts of epoxy resin, 5-10 parts of ethylene-vinyl acetate copolymer, 2-4 parts of polyisocyanate and 3-5 parts of magnesium acrylate. Magnesium acrylate is added into a high-temperature reaction kettle, an ethylene-vinyl acetate copolymer is added, the capillary infiltration capacity of epoxy resin is inversely proportional to the crack width, the smaller the width is, the more obvious the capillary action is, and the higher the capillary infiltration capacity is; the ethylene-vinyl acetate copolymer and the polyisocyanate improve the flexibility, impact resistance, filler intermiscibility and heat sealing performance, the boiling point of the isophorone diisocyanate is high, and the isophorone diisocyanate is matched with the ethidene diamine to reduce the influence of external temperature and humidity on the repairing effect.
本发明提供一种道路桥梁裂缝用速效型修复条，涉及道路桥梁裂缝加固技术领域。该道路桥梁裂缝用速效型修复条，包括固化原料组、修复原料组与稳定原料组，所述修复原料组包括以下重量份数的原料：环氧树脂30‑40份，乙烯‑醋酸乙烯酯共聚物5‑10份，多异氰酸酯2‑4份，丙烯酸镁3‑5份。通过将丙烯酸镁加入至高温反应釜内，并添加乙烯‑醋酸乙烯酯共聚物，环氧树脂的毛细渗透能力与裂缝宽度成反比，宽度越小毛细作用越发明显，毛细渗透能力越强，而乙烯‑醋酸乙烯酯共聚物以及多异氰酸酯提高了柔韧性、抗冲击性、填料相溶性和热密封性能，异佛尔酮二异氰酸酯的沸点较高，配合乙二胺，降低外界温度以及湿度对修复效果的影响。
