Abstract

The invention discloses an anti-corrosion paste. The anti-corrosion paste is prepared from the following components in percentage by weight: 35 to 80 percent of basic grease, 0.5 to 5 percent of high-permeability corrosion inhibitor, 0.5 to 20 percent of surfactant, 18 to 30 percent of thickening agent and 1 to 10 percent of plasticizer. The invention further discloses a preparation method of the anti-corrosion paste. The anti-corrosion paste is suitable for corrosion prevention of a concrete member in a water level change area, so that underwater construction is convenient, a water layer on the surface of concrete can be effectively replaced, pores on the surface of the concrete can be fully filled, the anti-corrosion paste has high crack followability, meanwhile, the permeable corrosion inhibitor can permeate into the concrete to effectively protect reinforcing steel bars, and the comprehensive anti-corrosion effect is excellent.

Description

technical field [0001] The invention belongs to the technical field of concrete anticorrosion, and specifically relates to a durable protective material suitable for concrete components in water level fluctuation zones and a preparation method thereof. Background technique [0002] The water level fluctuation area (including the tidal range area and the splash area) is the most severely corroded part of the bridge in the water environment, reaching 2 to 5 times the deterioration rate of the full immersion area. Solving the problem of concrete corrosion in the water level fluctuation area is an important part of improving the construction quality of the whole bridge , one of the key factors to ensure the service life of the bridge. Relying solely on the concrete layer is difficult to resist the comprehensive effects of corrosive medium penetration, dry-wet cycle, water erosion, and biological pollution. Therefore, applying surface protection is a necessary measure to resist c...
