Alkylated rust-preventative oil for metal parts

Abstract

The invention discloses alkylated rust-preventative oil for metal parts. The alkylated rust-preventative oil for metal parts is composed of the following raw materials in parts by weight: 0.8-1 parts of erythritol, 70-80 parts of 400sn basic oil, 2-4 parts of oleic acid polyoxyethylene ester, 2-5 parts of paraffin, 1-2 parts of dimethylpropylmethane, 1-2 parts of benzotriazole, 1-2 parts of zinc dialkyl dithiophosphate, 0.5-2 parts of sodium nitrite, 2-4 parts of ethyl acetyl citrate, 0.4-1 part of methylisobutylketone, 0.5-1 part of dialkyl hydroquinone, 15-20 parts of rare-earth corrosion-inhibition hydraulic oil, 0.2-0.4 part of polysiloxane and 1-3 parts of glycerinum. The rare-earth rust-preventative hydraulic oil is added to the rust-preventative oil disclosed by the invention; a great synergistic effect can be acted by mixing polyepoxysuccinic acid with phosphate, and a stable corrosion-inhibition function is realized; an aluminosiloxane sol is capable of promoting the compatibility among the various materials and improving the film-forming effect of the finished product; the added rare-earth ions are capable of generating insoluble complexes with the OH<-> generated during an oxygen absorption corrosion process on the surface of a metal base material, slowing down the electrode reaction of the corrosion and acting a great slow-release effect.

Description

[0001] technical field [0002] The invention mainly relates to the field of lubricating oil, in particular to an alkylated antirust oil for metal parts. Background technique [0003] During the storage, transportation and use of metals, due to the influence of water vapor, oxygen, acid, alkali, salt and carbide in the ambient atmosphere, physical and chemical changes will occur under certain temperature, humidity and time extension conditions. rust due to change. 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. Corrosion is one of the main forms of damage to fasteners, which will cause great losses to automobiles, motorcycles, various vehicles and machinery. . According to statistics, the annual direct economic loss caused by metal corrosion accounts for about 2% to 4% of the total output value of th...

Problems solved by technology

According to statistics, the annual direct economic loss caused by metal corrosion accounts for about 2% to 4% of the total output value of the national economy. Material is the most common method, and there are many problems in today's anti-rust oil, such as corrosion resistance, durability, adhesion, poor, prone to hardening, falling off, cracking, so it is necessary to continuously improve the anti-rust oil Comprehensive quality, to achieve better rust and corrosion inhibition effect
