TBN Boosters (Total Base Number)

TBN boosters are critical additives in lubricant formulations such as internal combustion engine (ICE) oils, marine oils, and other high-performance lubricants. They function by neutralizing acids that form during combustion and by enhancing the detergency and rust protection of the oil. The proper use of TBN boosters helps maintain engine performance, prolong lubricant life, and protect sensitive engine components under demanding operating conditions.

Types of TBN Boosters

  • Magnesium-Based TBN Booster
  • Calcium-Based TBN Booster

A. Magnesium-Based TBN Booster

Chemical Composition: A super overbased synthetic magnesium sulfonate produced through the neutralization of long-chain linear alkylbenzene sulfonic acid, followed by a high alkalization reaction.

Key Properties

  • Acid Neutralization: Neutralizes acids produced during combustion, preventing corrosion.
  • Anti-Rust Performance: Provides excellent protection against rust, especially in high-temperature environments where moisture is present.
  • High-Temperature Detergency: Enhances the cleaning ability of the lubricant by preventing the build-up of sludge and deposits.

Applications

Primarily used in internal combustion engine oils where robust acid neutralization and rust prevention at elevated temperatures are essential.

Usage Recommendations

  • Dosage: Varies, typically in a formulation at a level that maintains the desired TBN value.
  • Blending Conditions: Maximum recommended blending temperature is approximately 90°C.
  • Stability: Remains stable for at least 1 year when stored properly.

B. Calcium-Based TBN Booster

Chemical Composition: An overbased calcium petroleum sulfonate designed to perform effectively even with high sulfur content in fuels.

Key Properties

  • Rust Prevention: Provides excellent rust and corrosion protection, a key feature in environments with moisture and high temperatures.
  • Detergency: Improves the self-cleaning properties of the lubricant by maintaining engine cleanliness.
  • Dispersant and Corrosion Inhibition: Acts as a dispersant to keep contaminants in suspension and inhibits corrosion to protect engine parts.
  • Non-Staining: Does not discolor or leave residue on engine components, ensuring aesthetic and functional benefits.
  • Environmental Friendliness: Biodegradable and non-toxic, making it an eco-friendly option.

Applications

Ideal for use in marine oils and high-sulfur fuel engine oils. Also used as a short-term rust preventer and dispersant in various engine oil formulations.

Usage Recommendations

  • Dosage: Typically determined to achieve the necessary TBN level; adjusted based on formulation requirements.
  • Blending Conditions: Recommended maximum blending temperature is around 90°C (specific to some products, e.g., when lower temperatures are used, blending may be adjusted to prevent degradation).
  • Stability: Stable for at least 1 year when stored under appropriate conditions (cool, shaded areas not exceeding 40°C).

Environmental Advantages The calcium-based boosters, in particular, are biodegradable and non-toxic, meeting eco-friendly formulation requirements.

TBN boosters, including both magnesium-based and calcium-based formulations, are indispensable in modern lubricant technology. They improve the performance and longevity of lubricants by providing essential acid neutralization, enhanced detergency, and robust rust protection. These additives are particularly valuable in high-performance engine oils and marine lubricants, where they ensure cleaner operation and extended equipment life, even under adverse conditions. By incorporating these high-quality TBN boosters, lubricant formulators can optimize the protective properties of their oils, achieving improved engine performance, reduced maintenance costs, and enhanced environmental compatibility.
