Hydrophilic aluminum foil coated nano material and preparation method is a major piece for aluminum heat exchange, so that it has excellent corrosion resistance. Self-lubricating ability and excellent hydrophilic properties, the coating material is made of hydrophilic polymer A and a hydrophilic polymer nano-composite surface or particles B, wherein the hydrophilic polymer A include polyether, hydrophilic polymeric nano macromolecular compound particles B comprises a surfactant 5-50% (wt), acrylamide 20-90% (wt), acrylic acid 10-80% (wt), can be cross-linked unsaturated monomer 1-30% (wt ), the mass ratio of the hydrophilic polymer A hydrophilic polymer nano particles B is 9 to 9:1, to calculate the weight of the water-soluble polymer A and methanol was added at room temperature to dissolve the ingredients added to the kettle after ionized water, alcohol blue, mildew, even after mixing nano-added hydrophilic polymer particle B, then stir to obtain a nano hydrophilic aluminum foil after the coating material.

A book, a nano hydrophilic aluminum foil coating material as claimed in claim wherein the coating material comprises a hydrophilic polymer A and the hydrophilic polymer nano-composite surface or particles B, wherein A comprises a hydrophilic polymer polyethers, hydrophilic polymer nano particles B comprise macromolecular surfactant 5-50% (wt), acrylamide 20-90% (wt), acrylic acid 10-80% (wt), the crosslinkable unsaturated monomer 1-30% (wt), the quality of the hydrophilic polymer A hydrophilic polymer nano particles B ratio of 9 to 9 to 1.
