Problems solved by technology

[0002] 40Cr steel is one of the most widely used steels in my country's machinery manufacturing industry. After quenching and tempering treatment, it has good comprehensive mechanical properties, good low-temperature impact toughness and low notch sensitivity, and is suitable for making molds. In order to improve the surface resistance of 40Cr steel Corrosion, anti-rust treatment needs to be carried out on the surface of 40Cr steel. At present, most of the anti-rust processes in my country are treated with chromic acid or dichromate solution. The raw materials contain hexavalent chromium and trivalent chromium, which are harmful to human health and the environment. Cause serious harm, various anti-rust agents developed for the above defects have unstable quality, poor self-healing performance, and fail to meet customer needs

Abstract

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.
