Abstract

The invention discloses a multifunctional nanometer composite heat insulation film. The multifunctional nanometer composite heat insulation film is formed by sequentially arranging a fog and wear resistant layer, a first PET layer, a discoloration nanometer heat insulation layer, a second PET layer, an installation layer and a release layer, and the fog and wear resistant layer is formed through coating an ultraviolet-curable fog resistant coating and carrying out light curing; the first PET layer is coated with a discoloration nanometer heat insulation adhesive, the obtained layer is heated and dried, and the heated and dried layer is compounded with the second PET layer; the discoloration nanometer heat insulation layer is formed by the discoloration nanometer heat insulation adhesive; the installation layer is formed by an installation adhesive; and the release layer is a polyester film with the surface subject to a low energy process. The composite heat insulation film has fog resistance, heat insulation, discoloration and ultraviolet resistance functions, can automatically change its color with the external temperature change or light irradiation, has good optical performances, high visible light transparency, high ultraviolet and infrared blocking rate and good mechanical performances, is sturdy and wearable, can resist high and low temperature, and has good adhesion on glass substrates. The invention also discloses a making method of the multifunctional nanometer composite heat insulation film.

Description

technical field [0001] The present invention relates to a multi-functional nano-composite heat-insulating film, especially a double-layer PET composite heat-insulating film in which color-changing micropowder and nano-ATO are used as a heat-insulating medium; in addition, the present invention also discloses the aforementioned multi-functional nano-composite heat-insulating film molding method. Background technique [0002] Solar insulation film is a common energy-saving material, usually used in construction, automobile and other industrial fields. At present, the common heat insulation film on the market is mainly composed of 5 parts, including the surface anti-scratch coating, the safety substrate layer, the heat insulation layer, the installation layer, and the release film layer. The anti-scratch layer on the surface is usually formed by UV-curable coating, the safety substrate is usually made of optical grade PET film or double-layer PET composite film, and the heat i...
