The invention discloses a 40Cr steel surface antirust agent. The 40Cr steel surface antirust agent consists of the following components in percentages by
mass: 10-14% of
barium petroleum sulfonate, 4-7% of 80# micro-crystalline
wax, 59% of commercial
castor oil, 11-14% of waterborne
acrylic resin, 3-4% of
naphthalene, 2-3% of 96% concentrated
hydrochloric acid, 1-3% of crospovidone, 1-2% of a
wetting agent, and 1-2% of a defoaming agent. Excellent materials are selected, a scientific
processing method is adopted, the problem that the surface of existing steel can be corroded is solved, and antirust operation is facilitated; the commercial
castor oil is used as a dispersion medium, and is
environmentally friendly and
pollution-free; the 40Cr steel surface antirust agent does not contain methylbenzene,
ethylbenzene or dimethylbenzene, is low in VOC and does not contain
formaldehyde, the heavy
metal content is lower than the national compulsory standard, irritating
odor does not exist,
surface corrosion,
cavitation and scaling of the steel can be prevented, a protecting layer is formed, time of
rust generation of the surface of the steel is prolonged,
chromic acid or dichromate in a formula is avoided, and the 40Cr steel surface antirust agent is low in cost, non-toxic, and excellent in construction performance, does not have adverse effects on
skin, and has remarkable environmental benefit, economic benefit and social benefit.
