Abstract

The invention discloses a shielding film for exterior wall glass and a preparation method thereof, and particularly relates to the technical field of shielding films. The shielding film comprises polyethylene resin, starch, an antioxidant, an ultraviolet light absorber, a composite filler and an organic solvent. The anti-adhesion performance, the anti-aging performance, the high temperature resistance and the illumination resistance of the shielding film can be effectively improved, the shielding film can be effectively prevented from being attached to the surface of glass in the using process, and the cleanliness of exterior wall glass is guaranteed; after the starch, the organic solvent and the composite filler in the formula are subjected to blending ultrasonic treatment, the stability of electrostatic spinning processing is ensured; and graphite in the formula forms nano layered graphite after being subjected to microwave irradiation stripping treatment, and part of nano silver particles enter a deep layer of expanded graphite along with deionized water, so that the distribution uniformity of the nano silver particles in the shielding film can be effectively ensured, and meanwhile, the stability of the shielding film is enhanced, and the nano-silver and the silicon dioxide are prevented from being separated from the shielding film under high-strength long-time illumination.

Description

technical field [0001] The invention relates to the technical field of shielding films, more specifically, the invention relates to a shielding film for exterior glass and a preparation method thereof. Background technique [0002] Masking film, mainly used for covering paint, shielding paint and film materials for interior decoration during the painting process of automobiles, ships, trains, cabs, furniture and other products. The products are divided into high temperature resistant and normal temperature. The masking film is PE film As the substrate, it is made of adhesive tape. The masking film can prevent paint leakage, effectively improving the traditional masking method of using newspaper and textured paper. The glass curtain wall refers to the mirror glass of the exterior wall decoration of the building, which can absorb infrared rays and reduce the solar radiation entering the room, thereby reducing the indoor temperature. The glass curtain wall can not only reflec...
