LUBRICANT COMPOSITION FOR FIN, FIN AND HEAT EXCHANGER

Title:

LUBRICANT COMPOSITION FOR FIN, FIN AND HEAT EXCHANGER

Document Type and Number:

Japanese Patent JP2007084695

Kind Code:

A

Abstract:

To provide a lubricant composition which can improve the drying properties of volatile press oils and reduce the stay of the volatile press oils on the surfaces of the fins.

This lubricant composition for fins comprises a lubricant component (I) having surface tension of ≥50 [mN/m] in a 1 mass% aqueous solution and a hydrophilic resin (II) prepared by partially neutralizing the acid groups of a ternary copolymer comprising a carboxy group-having monomer (a1), a hydroxy group-having monomer (a2) and an amide group-having monomer (a3). Thereby, the drying properties of volatile press oils can be improved, and the stay of the volatile press oils on the surfaces of fins can be reduced. No problem is caused in an air tightness test by the water immersion method of a heat exchanger.
