Special rustproof oil for iron powder stamped parts

Abstract

The invention discloses special rustproof oil for iron powder stamped parts. The rustproof oil is prepared from the following raw materials in parts by weight: 70-80 parts of No. 30 mechanical oil, 2-3 parts of dimethyl tetrachloroterephthalate, 0.4-1 part of dioctylmethyl tertiary amine, 4-6 parts of a rustproof agent t746, 0.5-1 part of xylene, 0.5-2 parts of polytetrafluoroethylene, 2-3 parts of dimethyl fumarate, 1-2 parts of benzotriazole, 1-2 parts of calcium ricinoleate, 6-10 parts of liquid paraffin, 2-3 parts of ethylene glycol, 0.6-1 part of phytic acid, 1-2 parts of triethanolamine and 14-20 parts of rare earth film-forming hydraulic oil. Rare earth film-forming hydraulic oil is added into the rustproof oil; propylene glycol phenyl ether is added into a modified gelatin system disclosed by the invention, propylene glycol phenyl ether is completely absorbed by the gelatin system particles and thus the coalescence property and stability of the system are increased and the film-forming property of the rare earth film-forming hydraulic oil is enhanced; and added rare earth ions can react with OH- generated in oxygen absorption corrosion process happening on the surface of a metal substrate to produce an insoluble complex and thus the corrosive electrode reaction is alleviated and good corrosion-inhibition effect is achieved.

Description

technical field [0001] The invention mainly relates to the field of lubricating oil, in particular to a special antirust oil for iron powder stamping parts. Background technique [0002] 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 va...

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
