Black bright antirust oil

Abstract

The invention discloses a black bright antirust oil which is prepared from the following raw materials in parts by weight: 4-6 parts of coal tar, 1-2 parts of methyl perfluoro-nonyl ketone, 0.5-1 part of copper chrome black, 0.5-1 part of lauryl nitro tropone, 60-70 parts of N68 machine oil, 1-2 parts of formamide, 0.5-1 part of fluorinated ethylene propylene copolymer, 1-2 parts of chitin, 2-4 parts of castor oil, 2-4 parts of tributyl citrate, 2-6 parts of chlorinated paraffin wax, 0.5-2 parts of lauroyl diethanolamide, 0.6-1 part of N-hydroxymethyl acrylamide, 0.5-1 part of ammonium molybdate, 3-5 parts of antifriction machine oil and 0.4-1 part of calcium lactate. The antifriction machine oil added into the antirust oil can form a molecular orientation adsorption film on the metal surface to reduce the friction; the obtained modified terpene resin has favorable binding property and high heat stability, and can enhance the compatibility among the materials and increase the adhesion of the coated film; the zinc dihydrogen phosphate used as a common metal surface treating agent has favorable derusting and antiseptic effects; and the added rare-earth lanthanum ions can be combined with -OH, which is generated in the oxygen-absorption corrosion process on the metal substrate surface, to generate an insoluble complex, thereby decelerating the corrosive electrode reaction and having favorable slow release effect.

Description

technical field [0001] The invention mainly relates to the field of lubricating oil, in particular to a black bright antirust oil. Background technique [0002] Corrosion is one of the main forms of damage to fasteners, and it will cause great losses to automobiles, motorcycles and various vehicles and machinery. According to statistics, the annual direct economic loss caused by metal corrosion accounts for about 2-4% of the total output value of the national economy. Under the influence of substances such as carbides, under certain conditions of temperature, humidity and time extension, physical and chemical changes will occur and rust will occur. The corrosion of metal will cause the loss of metal and the decline and loss of the function of metal parts. Metal corrosion is caused by the oxidation reaction of metal in contact with moist air or electrolyte solution. Therefore, it is necessary to continuously improve the anti-rust effect of anti-rust oil, prolong the...
