Corrosion inhibitor for additive reinforced concrete and preparation method for corrosion inhibitor

Abstract

The invention discloses a corrosion inhibitor for additive reinforced concrete and a preparation method for the corrosion inhibitor. The invention aims to overcome the defects that a nitrite corrosion inhibitor is toxic, and the environment is polluted. The corrosion inhibitor for the additive reinforced concrete is prepared from the following components in weight percentage: 5-10 percent of sodium molybdate, 25-40 percent of calcium gluconate, 40-50 percent of polyaspartic acid and 10-15 percent of sodium dodecyl sulfate. The corrosion inhibitor for the additive reinforced concrete has the characteristics of good corrosion-prevention effect, low cost, convenience in use and environmental friendliness. The durability of a reinforced concrete structure can be effectively improved, and the long service life of the reinforced concrete structure is ensured.

Description

technical field [0001] The invention relates to an anti-corrosion material, in particular to an additive-type corrosion inhibitor for reinforced concrete and a preparation method thereof. Background technique [0002] Reinforced concrete structure combines the advantages of steel bars and concrete, and has a low cost. It is the preferred form of engineering structure design. Since the beginning of the last century, concrete structures have been increasingly widely used. As time goes by, people have gradually realized that the deterioration of concrete structures under many environmental conditions is difficult to meet the design requirements. The second concrete durability conference held in France in 1991, Professor Mehta pointed out that the main causes of concrete damage are corrosion of steel bars, freezing damage in cold climates, and physical and chemical effects in erosive environments, among which corrosion damage to steel bars has been identified as the first factor...
