Problems solved by technology

According to the statistics of the test data, it is known that the antirust effect of barium-free antirust oil is not as good as that of barium-containing antirust agents (such as barium petroleum sulfonate, barium dinonyl naphthalene sulfonate, etc.) Excellent performance, but barium is a heavy metal, and its compounds will cause harm to the human body, and can cause death in severe cases
Although the oil-soluble barium antirust agent used in conventional antirust oil itself is a non-toxic organic compound, it will decompose into soluble barium salts when it is scattered in nature, thereby generating toxic substances, which have serious harm to the human body and the environment. harm
[0006] Patent CN103992842 discloses a quick-drying spray anti-rust oil for automotive cast iron engine workpieces. The invention is a quick-drying anti-rust oil, but its components contain barium corrosion inhibitors; Quick-drying anti-rust oil for engine workpieces and its preparation method. The invention is a quick-drying anti-rust oil, but its components also contain barium corrosion inhibitors; patent CN104531299 discloses a

Abstract

The invention discloses environment-friendly nodular cast iron antirust oil which comprises the following components in parts by weight: 0.2-1 part of a corrosion inhibitor, 17-26 parts of an antirustagent, 0.1-1 part of an antioxidant, 1-3 parts of a film-forming agent, 2-8 parts of a dispersing agent, 30-50 parts of base oil and 20-50 parts of environment-friendly solvent oil. The antirust agent comprises lanolin metallic soap and mahogany petroleum sulfonate. Under the condition that barium and other heavy metal elements are not contained, the salt mist resistance, the damp-heat resistanceand the water replacement performance of the ductile iron casting all reach the rust prevention effect of barium-containing rust prevention oil, the long-term marine transportation rust prevention requirement can be met, and marine transportation is facilitated; and because of not containing barium and other heavy metal elements, the application range is wider, and export is facilitated.

Description

technical field [0001] The invention relates to an antirust oil, in particular to an environment-friendly nodular cast iron antirust oil. Background technique [0002] Ductile iron is a high-strength cast iron material developed in the 1950s. Its comprehensive properties are close to steel. The so-called "substituting iron for steel" mainly refers to ductile iron. Based on its excellent performance, it has been successfully used to cast some parts with complex stress, high strength, toughness and wear resistance, and it has rapidly developed into a widely used cast iron material second only to gray cast iron. [0003] Ductile iron belongs to the category of cast iron. Cast iron is an iron-carbon alloy with a carbon content greater than 2.11%. It is obtained from industrial pig iron, scrap steel and other steel and its alloy materials through high-temperature melting and casting. In addition to Fe, it also contains other components. The carbon in cast iron is precipitated in...
