The secret of lubricant additive formula is revealed - no less is enough!

As we all know, lubricating oil is generally composed of two parts: base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil, and additives can make up for and improve the shortcomings of base oil performance, give some new properties, and are an important part of lubricating oil.

75%-95% of our engine oil is base oil, and additives only account for 5%-25%, although the proportion is small, but extremely important!

So, do you really know about additives?

What are lubricant additives

Lubricant additives are one or several compounds added to a lubricant to obtain some new properties or improve some of the properties already existing in the lubricant.

Types of lubricant additives

Lubricating oil additives can be divided into cleaning and dispersing agents, antioxidant and anticorrosive agents, extreme pressure anti-wear agents, oily agents and friction modifiers, antioxidants and metal deactivators, viscosity index improvers, rust inhibitors, pour point depressants, antifoam agents, etc.

The role of lubricant additives

Cleaning dispersant

There are two types of detergents and dispersants.

It is mainly used for internal combustion engine oil (gasoline engine oil, diesel engine oil, railway diesel locomotive oil, two-stroke engine oil and marine engine oil).

Its main function is to keep the inside of the engine clean, so that the insoluble substances generated are in a colloidal suspension state, so that no further formation of carbon deposits, paint film or sludge. Specifically, its role can be divided into four aspects: acid neutralization, solubilization, dispersion and washing.

Antioxidant and antiseptic

Antioxidants and antioxidants can inhibit the oxidation of oil and improve the stability of oil oxidation.

It is mainly used for industrial lubricants, internal combustion engines and process oils.

Extreme pressure anti-wear agent

The products decomposed at high frictional temperatures can react with metals to form compounds with lower shear stress and melting points than pure metals, thus preventing contact surface seizure and welding, and effectively protecting metal surfaces.

Extreme pressure anti-wear agent is mainly used in industrial gear oil, hydraulic oil, guide oil, cutting oil and other lubricating oils with extreme pressure requirements, so as to improve the extreme pressure anti-wear performance of oil.

Oil-based agents

An oily agent is a surfactant with a polar group at one end of the molecule and an oil-soluble hydrocarbon group at the other.

The substance containing this polar group has a strong affinity for the metal surface, and it can be firmly and directionally adsorbed on the metal surface, forming a protective film similar to a cushion between the metals, preventing direct contact with the metal surface and reducing friction and wear.

Viscosity index improver

Also known as thickener, it can not only increase the viscosity of oil,

It can also improve the viscosity and temperature performance of the oil.

Rust inhibitors

A firm adsorption film is formed on the metal surface to inhibit the contact between oxygen and water, especially water, on the metal surface, so that the metal does not corrode.

With the development of industrial technology, the high speed, high performance, high automation, high efficiency and long life required by modern equipment are difficult to meet with mineral oil lubricating materials in terms of lubrication. Additives can give lubricating materials new properties and play an important role in the performance of lubricating oils.
