Concrete rust inhibitor

Abstract

The invention discloses a concrete rust inhibitor. The concrete rust inhibitor comprises the following components in parts by weight: 1-8 parts of sodium molybdate, 300-500 parts of diethylenetriamine, 80-180 parts of allyl thiourea and 100-180 parts of benzoic acid. According to the concrete rust inhibitor, the corrosion of steel bars in reinforced concrete can be effectively retarded and prevented, and the damage caused by chloride ions to passivation coatings of the steel bars can be prevented or retarded.

Description

technical field [0001] The invention relates to an antirust agent, in particular to a concrete antirust agent. Background technique [0002] Traditional rust inhibitors need to be used in large quantities in reinforced concrete, and their ability to prevent steel bars from being corroded is poor. Contents of the invention [0003] The object of the present invention is to provide a concrete rust inhibitor to solve one or more of the above-mentioned problems in the prior art. [0004] According to one aspect of the present invention, a concrete rust inhibitor is provided, comprising 1-8 parts of sodium molybdate, 300-500 parts of diethylenetriamine, 80-180 parts of propenylthiourea, and 100-180 parts of benzoic acid. [0005] During production, add all the above materials into the mixing tank, add water with a mass ratio of 30%, and stir to mix evenly. [0006] The concrete rust inhibitor of the invention can effectively slow down and prevent the corrosion of steel bars i...
