The invention discloses a high-performance nanometer composite heat insulation film. The high-performance nanometer composite heat insulation film is formed by sequentially arranging a
wear resistant layer, a first PET layer, a magnetron
sputtering layer, a nanometer heat
insulation layer, a second PET layer, an installation layer and a release layer. The
wear resistant layer is formed through
coating an
ultraviolet-curable
coating and curing; the first PET layer undergoes magnetron
sputtering and then is coated with a nanometer heat insulation
adhesive, and the obtained layer is compounded with the second PET layer; the nanometer heat
insulation layer is formed by
coating the nanometer heat insulation
adhesive and
drying; the installation layer is formed by coating an installation
adhesive and
drying; and the release layer is a surface treated
polyester film. The composite heat insulation film made in the invention has excellent optical performances, a visible light
transmittance of above 55%, an
ultraviolet ray blocking rate of above 99% and an
infrared ray blocking rate of above 90%, and has the advantages of good mechanical performance, sturdiness, dampness resistance, scratch resistance, high and low
temperature resistance, simple operation during installation, and firm bonding to glass. The invention also discloses a making method of the high-performance nanometer composite heat insulation film.
