Abstract

The invention discloses an aqueous rust preventive capable of improving deformed steel bar concrete holding and wrapping performance. The aqueous rust preventive comprises raw materials including, byweight, 5%-15% of zircon salt, 2%-8% of sodium hypophosphite, 0.5%-5% of alkali, 0.1%-0.5% of a corrosion inhibitor, 0.1%-0.5% of a stabilizer, 0.05%-0.08% of nickel fluoride, 0.05%-0.1% of tert-butylhydroquinone, 0.02%-0.05% of potassium oxalate and the balance water. Compared with the prior art, the rust prevention effect is obvious, and the outdoor atmospheric and rain corrosion resistant performance is excellent; in addition, a high temperature deformed steel bar is free of obvious pungent smells in the rust prevention treatment process, the air environment of a steel rolling site is facilitated, and influences on the body health of operators are reduced; and meanwhile, the holding and wrapping strength of the deformed steel bar and concrete can be greatly improved after rust prevention treatment is treated.

Description

technical field [0001] The invention belongs to the field of iron and steel manufacturing, and in particular relates to an environment-friendly antirust treatment agent for the surface of threaded steel. Background technique [0002] Hot-rolled ribbed steel bar, commonly known as rebar, is the steel product with the largest amount of steel used in construction at present. As the skeleton material of reinforced concrete, rebar is widely used in various modern engineering constructions such as bridges, ports, dams, docks, platforms, roads, industrial and civil buildings. In recent years, in order to produce low-cost high-strength steel bars, most iron and steel enterprises have adopted the water-piercing cooling process after final rolling. This process can improve the structure to a certain extent and improve the mechanical properties of steel bars, but there is a big disadvantage in this process, that is, the rebars cooled by water are easy to rust during storage and transp...
