Abstract

The invention provides a heat-insulating film with high ultraviolet barrier property and a preparation method thereof. A section of the heat-insulating film has a layered structure sequentially including an anti-scratch layer, a base film, an ultraviolet barrier compound layer, a base film, an ultraviolet barrier installation adhesive layer and a release film, wherein the ultraviolet barrier compound layer and the ultraviolet barrier installation adhesive layer are formed by coating an ultraviolet absorption paint, the ultraviolet absorption paint at least comprises an ultraviolet light absorbent, a pressure-sensitive adhesive and a solvent; and the anti-scratch layer is formed by coating a photocuring paint or a photocuring nanometer heat-insulating paint, and the photocuring paint or the photocuring nanometer heat-insulating paint at least comprises photocuring resin and auxiliaries. The prepared heat-insulating film has high-weather-resistant, high-definition and high-ultraviolet barrier properties, the infrared barrier rate is greater than 85%, the haze degree is less than 0.1%, the ultraviolet permeability of the UVA long wave band is less than 1%, and the ultraviolet barrier property has no attenuation after being irradiated for 7 hours under the ultraviolet intensity of 100mw / m<2>.

Description

technical field [0001] The invention relates to a composite heat-insulating film, in particular to a heat-insulating film with high ultraviolet blocking performance and a preparation method of the composite film, belonging to the technical field of composite film processing. Background technique [0002] Solar film, also known as thermal insulation film, is widely used in automobiles and architectural glass windows. The main function of the heat insulation film is to block the ultraviolet and infrared energy in the sun. The former can reduce the damage of ultraviolet rays to the skin and interior decoration, and improve the service life of the heat insulation film itself; the latter can reduce the sunlight energy entering the room, thereby reducing Air conditioning energy consumption in summer. [0003] The ultraviolet energy in sunlight is mainly concentrated in the 200nm-400nm band range, which is divided into UVC (200nm-280nm), UVB (280nm-315nm) and UVA (315nm-400nm) ban...
