A high-permeability epoxy waterproof coating material includes a first fluid and a second fluid. The first fluid by mass percentage includes 50-75% bisphenol A epoxy resin, 5-15% reactive diluent, 10-20% epoxy resin toughening agent, and 20-40% benzene diluent. The second fluid by mass percentage includes 15-20% polyether amine D2000, 10-15% D230, 50-70% diluent, 2-5% accelerant, and 20-30% benzene diluent. The first fluid is mixed with the second fluid to obtain the coating material. The coating material has strong permeability and good flexible, and is able to penetrate and repair surface cracks and pores of the concrete, for forming a layer of sealed integral waterproof structure on the concrete surface. Even if the surface film forming material is destroyed, the concrete surface is also closed by the coating, so as to form the dense waterproof structure, thereby achieving the permanent water proofing. |
