Technical Field

The invention belongs to the technical field of lubricants, and particularly relates to a rust removing and preventing lubricant and a preparation method thereof.

Background

With the development of economy, large and medium-sized enterprises, particularly the industries such as ships, machinery, metallurgy, exploration and the like, are rapidly emerging, and the replacement or the maintenance of some mechanical equipment can be involved in modern industrial production or daily maintenance and repair. However, some problems causing headache are encountered in the process of disassembling the mechanical equipment, and some iron or steel metal bolts or parts are locked by rust or pollutants in the operation of daily working equipment, so that the construction cannot be carried out, and the construction is time-consuming and labor-consuming.

In order to solve the above technical problems, a large amount of rust removing lubricants are now on the market. The rust removing lubricant is generally composed of base oil and additives. The base oil is the main component of the rust-removing lubricant, the basic properties of the rust-removing lubricant are determined, the additives can make up and improve the defects of the base oil in terms of performance, and the additives endow certain new performances and are an important component of the rust-removing lubricant. However, through professional tests and analysis, the existing rust removing lubricant is found to have the following problems: 1) the rust removal efficiency is low, only rust can be removed, and other pollutants cannot be removed; 2) after rust removal, the water-repellent rust-proof time of the surface of the treated object cannot be effectively prolonged, and the treated object is easy to rust again in a short time.

3) adding a surfactant into the reaction kettle in the step 3), and stirring and mixing uniformly to obtain the rust removing and preventing lubricant.

The third purpose of the invention is that: the rust removing and preventing lubricant is applied to a position of a workpiece needing rust removing and lubricating by coating, the workpiece is repeatedly coated until rust on the workpiece is completely removed, and finally the workpiece is taken out and then put into clean water to be rinsed.

As an improvement of the application of the rust removing and preventing lubricant, for the serious rust of the workpiece, the rust removing and preventing lubricant is directly soaked in the rust removing and preventing lubricant, or the temperature of the rust removing and preventing lubricant is heated to 45-55 ℃ before being coated.

Compared with the prior art, the beneficial effects of the invention include but are not limited to:

1) the invention adopts biodegradable base oil matched with organic environment-friendly rust dissolving agent and antirust agent, can quickly permeate along rust and other pollutants, has quick rust removing, lubricating and antirust effects, and is environment-friendly.

2) According to the rust-removing and rust-preventing lubricant, the fatty glyceride and the modified castor oil are added to serve as base oil, the fatty glyceride and the modified castor oil can play a lubricating role, the modified castor oil belongs to vegetable oil, the glyceride contained in the lubricant is easy to hydrolyze, the biodegradation rate is high, the viscosity index is high, the viscosity temperature stability is good, and a protective film can be formed on the surface of metal, so that the rust-removing and rust-preventing lubricant has better performance, has small influence on a processed workpiece, and can prolong the service life of the processed workpiece.

3) The 68# engine oil, the zinc epoxide and the barium petroleum sulfonate are added, wherein the 68# engine oil and the barium petroleum sulfonate are mixed to be used as a rust dissolving agent, the rust dissolving agent can quickly permeate and dissolve iron rust, and the good lubricating and rust removing effects are achieved, and the zinc naphthenate and the barium petroleum sulfonate are matched to be used as an antirust agent, so that the good antirust effect can be achieved.

4) The invention also adds propylene glycol methyl ether which is used as a cleaning component and can remove other pollutants on the surface of the processed workpiece while removing rust and lubricating.
