HYDROPHILIC MEMBER AND METHOD FOR PRODUCING FIN MATERIAL FOR HEAT EXCHANGERS

WIPO Patent Application WO/2010/076872

A1

Disclosed is a hydrophilic member having excellent hydrophilicity, antifouling properties, lubricity, adhesion and anti-rust properties.  Also disclosed is a method for producing a fin material for heat exchangers having excellent hydrophilicity, antifouling properties, lubricity, adhesion and anti-rust properties. The hydrophilic member is characterized in that a hydrophilic layer, which is formed from a hydrophilic composition containing a hydrophilic polymer having a hydrolyzable silyl group, is provided on a base, and a lubricating layer having a friction coefficient of 0.05-0.25 is provided on the hydrophilic layer.  The method for producing a fin material for heat exchangers is characterized in that the surface of a fin material for heat exchangers, which has a hydrophilic layer that is formed by coating an aluminum plate surface with a hydrophilic composition containing a hydrophilic polymer having a hydrolyzable silyl group, and then drying the coating thereon, is coated with a lubricant composition and then the coating is dried thereon, so that the lubricant composition is adsorbed on or impregnated into the hydrophilic layer, thereby forming a lubricating layer having a friction coefficient of 0.05-0.25.
