Abstract

The present invention discloses an environmental protection type thread steel surface antirust treatment agent, which comprises, by weight, 5-15% of a zirconium salt, 2-8% of sodium hypophosphite, 0.5-5% of an alkali, 0.1-0.5% of a corrosion inhibitor, 0.1-0.5% of a stabilizer, 0.05-0.08% of nickel fluoride, 0.5-0.8% of phenyl ethylene glycol ether, 0.05-0.1% of tert-butylhydroquinone, 0.05-0.08% of glycerol monostearate, 0.05-0.08% of 4-sulfo phthalic acid, 0.02-0.05% of 2-sulfo phenylpropionic acid, and the balance of water. With the present invention, the commonly existing problem of easy rust during a storage and transportation process of the thread steel is solved, wherein a common water base antirust agent can heavily pollute an environment, and antirust oil can affect bounding stress between the thread steel and concrete. Compared with the antirust treatment agent in the prior art, the antirust treatment agent of the present invention has characteristics of significant antirust effect, long antirust time, low cost, no pollution and high safety.

Description

technical field [0001] The invention belongs to the field of surface treatment of threaded steel bars, and in particular relates to an environment-friendly antirust treatment agent for the surface of threaded steel bars. Background technique [0002] Hot-rolled ribbed steel bar is commonly known as rebar. The raw material billet for producing rebar is carbon structural steel or low-alloy structural steel that has been quenched and smelted. The finished steel bar is delivered in a hot-rolled, normalized or hot-rolled state. Due to the effect of ribs, rebar and concrete have greater bonding capacity, so they can better withstand external forces. Rebar belongs to small section steel, which is widely used in various building structures, especially the skeleton of reinforced concrete building components of large, heavy, light thin-walled and high-rise buildings. Rebar is used as construction steel, and its consumption has always occupied a large proportion of my country's steel ...
