I. Types and Characteristics of RustPreventive Additives
Rust preventive additives are categorizedbased on chemical structure and functionality:
  1. Sulfonates (e.g., composite barium sulfonate HA7404, calcium sulfonate HA C10)
  1. Carboxylic Acids (e.g., dodecenyl succinic acid HA746)
  1. Amine Compounds (e.g., fatty amines, imidazoline derivatives)
  1. Lanolin Magnesium Soap (metal soap-based additive HA M231)
  1. Composite Rust Inhibitors
II. Additive Formulation: BalancingScience and Craft
Optimal additive ratios maximize thestrengths of different rust inhibitors. Typical dosage ranges are as follows:
Additive Type
Typical Dosage
Key Features
Sulfonates
0.5%–2%
Cost-effective, broad applicability
Carboxylic Acids
0.3%–1.5%
Enhanced adhesion for precision parts
Amine Compounds
0.2%–1%
Synergistic protection in high temps
Composite Rust Inhibitors
1%–3%
Long-term protection for advanced needs
Lanolin Magnesium Soap
0.5%–2%
Non-ferrous metal protection, eco-friendly
Note: Forcopper alloy preservative oils, lanolin magnesium soap dosage may increase to2.5%. When blended with sulfonates, total additive content should not exceed 3%to prevent precipitation.
III. Future Trends and Applications
As industrial technology advances, rustpreventive additives continue to evolve. Future trends emphasize eco-friendlynatural ingredients, exemplified by the growing adoption of lanolin magnesiumsoap. Additionally, applications in electronics—particularly for coppercomponent protection—are gaining prominence.
By scientifically selecting and formulatingadditives, equipment service life can be extended, productivity enhanced, andmaintenance costs reduced, delivering significant economic and social benefits.
