Problems solved by technology

[0003] Ordinary track antirust grease is composed of base oil, film forming agent, antirust agent, etc. It has a short service life and is easily affected by high temperature and low temperature, and it will fail due to heat flow and low temperature cracking. It is a new task for scientific researchers to develop a new rail antirust oil with high temperature resistance, good freezing performance and long antirust time.

Embodiment 1

[0025] The composition ratio of each component of rail anti-rust oil is shown in the following table:

[0026] Composition Number of copies Base oil A 1

[0027] Take the base oil, anti-rust agent, and auxiliary agent according to the weight parts of the raw materials and add them into the reaction kettle and heat and stir at 120°C for 30 minutes, then add plasticizers, antioxidants, and film forming agents in sequence and continue stirring for 30 minutes until they are evenly mixed. , Vacuum filtration is performed again to obtain anti-rust oil product B1.

Embodiment 2

[0029] By adjusting the ratio of rust inhibitor aluminum stearate and calcium petroleum sulfonate, the role of rust inhibitor in the process of rust prevention was investigated. The composition ratio of each component of rail anti-rust oil is shown in the following table:

[0030] Composition Number of copies Base oil A 1

[0031] Take the base oil, anti-rust agent, and auxiliary agent according to the weight parts of the raw materials and add them into the reaction kettle and heat and stir at 120°C for 30 minutes, then add plasticizers, antioxidants, and film forming agents in sequence and continue stirring for 30 minutes until they are evenly mixed. , Vacuum filtration is performed again to obtain anti-rust oil product B2.

Embodiment 3

[0033] By removing the film-forming agent, the influence of the formation of the anti-rust film on the anti-rust effect was investigated. The composition ratio of each component of rail anti-rust oil is shown in the following table:

[0034] Composition Number of copies Base oil A 1

[0035] Take the base oil, rust inhibitor, and auxiliary agents according to the weight parts of the raw materials and add them to the reaction kettle and heat and stir at 120°C for 30 minutes, then add plasticizers and antioxidants in sequence and continue stirring for 30 minutes until they are uniformly mixed, and vacuum again Filter to obtain anti-rust oil product B3.

Abstract

The invention provides track antirust oil and a preparation method thereof, wherein the track antirust oil comprises the following components in parts by weight: 65-75 parts of base oil, 10-16 parts of an antirust agent, 5-10 parts of a plasticizer, 2-4 parts of an antioxidant, 1-3 parts of a film-forming agent and 1-3 parts of other auxiliary agents. The preparation method comprises the followingsteps: dewatering low-viscosity base oil, sequentially adding the raw material components, heating, stirring, and carrying out vacuum filtration to obtain the antirust oil product. According to the track antirust oil and the preparation method thereof, by using the film forming technology, the track antirust oil has strong adhesive force and less shedding; the track antirust oil is strong in adhesive force at a high temperature, does not flow, and does not crack at a low temperature; and by completely using engine oil with low viscosity as base oil, the track antirust oil has the characteristics of low cost, environmental friendliness and the like.

Description

Technical field [0001] The present invention relates to the technical field of new anti-rust materials, in particular to the preparation and use method of rail anti-rust oil. Background technique [0002] With the implementation of mid- and long-term railway network planning, my country’s railway construction has developed rapidly. Railway tracks are mainly composed of track rails, track fasteners, bolts and other components. The use of bolts and nuts as movable parts is extremely large. Sun and rain, wind and snow erosion, as well as the erosion of train excrement by acid, alkali, salt, and water, are prone to oxidation and chemical corrosion, which will cause heavy line maintenance and high maintenance costs, which will affect the normal railway Operation, there may even be security risks. Therefore, it is necessary to use rail anti-rust grease for smear protection. [0003] Ordinary road rail anti-rust grease, composed of base oil, film-forming agent, anti-rust agent, etc., has ...
