Abstract

The invention discloses a concrete waterproofing agent which is prepared from the following raw materials in parts by weight: 15-23 parts of hydrophobic fumed silica, 9-16 parts of superfine slag powder, 5-10 parts of sodium tall oil pitch sulfonate, 5-9 parts of dicyclohexylamine nitrite, 3-6 parts of octadecylamine, 7-9 parts of octyl dodecyl polyglucosides, 1-5 parts of 4-p-phenylphenol, 6-10 parts of water-based trihydroxymethylaminomethane-epoxy resin, 3-6 parts of mill wood lignin, 3-5 parts of gypsum, 1-5 parts of ethylene glycol, 5-10 parts of polyvinylpyrrolidone and 8-11 parts of silica-coated titanium dioxide. The concrete waterproofing agent disclosed by the invention has the beneficial effects that the concrete waterproofing agent has a good waterproofing effect and has good water-reducing and impervious effects.

Description

technical field [0001] The invention relates to a concrete waterproofing agent. Background technique [0002] After ordinary concrete is hardened under general curing conditions, there will always be a certain degree of water seepage or leakage. It is very important to improve the waterproof and impermeable performance of concrete. It has the function of improving the impermeability and waterproof of concrete, and the impermeability grade can reach above P25. At the same time, it has the functions of retarding, early strength, water reduction, and crack resistance, and can improve the workability of fresh mortar: it can replace lime paste. It is especially suitable for concrete for bungalow roofs, large-volume waterproof concrete, hydraulic concrete, waterproof mortar, etc. Existing waterproofing agents have shortcomings in varying degrees, and people are working hard to improve the performance of concrete waterproofing agents. Contents of the invention [0003] Aiming a...
