The second-hand naphthalene sulfonate can be strongly adsorbed on the iron oxide powder, and they have an unusually large umbrella shape, so that they can only interact with a few active sites on the surface of the metal oxide. As a result, small water molecules can penetrate the sulfonate layer and adsorb to the open position of the oxide. In the oil-containing corrosion inhibitor system, some polar components of the oil can be adsorbed on a part of the free position of the oxide, thus changing the balance of surface water and water in micelles, which helps the process of corrosion inhibition.

American King Industries, In e, u produces zinc salt and salt of dinonyl sulfonic acid. Nn corr 1552 is the zinc salt of dinonyl zephyl sulfonic acid, which can be used in solvent-based, water-based and high-solid coatings. During low-temperature baking, it can also act as a catalyst for cross-linking amino resins, thus helping to increase hardness. Na corr 1151 is the barium salt of dinonylnaphthalenesulfonic acid. For alkyd and expanded ptfe powder alkyd/melamine coatings, it can replace zinc chromate to provide corrosion resistance.

The zinc, calcium and sodium salts of aliphatic acids or aromatic acids are used as corrosion inhibitors in many aspects including coatings. Generally, the use of ammonium and sodium benzoic acid is effective in improving the flash corrosion resistance, but reduces Anti-salt spray and anti-impregnation properties. Barium salts of citric acid, tartaric acid or salicylic acid can be used as corrosion inhibitors in acrylic, alkyd, epoxy, polyvinyl acetate, rubber latex or chlorinated rubber coatings.

Petroleum fractions can be partially oxidized to produce hydrocarbon oxides, which are mixtures of carboxylic acids, hydroxy acids, lactones, esters, and unsaponifiables. The metal soap derived from it is a low-cost corrosion inhibitor that can be used in temporary protective coatings. A lox 165 prepared by American Alox Corp. 13J is such a type of corrosion inhibitor, which is a calcium salt. , It is compatible with petroleum hydrocarbons. 10% A lox 165 petroleum solvent solution can form a thin coating film, provide 60-day moisture resistance on the steel plate, and can also drive water away from the steel surface.
