Problems solved by technology

[0007] At present, automobile sunshade film is prepared by magnetron sputtering process and multi-layer coating with functional coating. Not only is the process complicated and the cost is high, but also aluminum plating affects light transmission, the aluminum layer is easy to fall off, and the metal layer is easy to cause strong reflections and other problems. For this reason, the present invention proposes a sunscreen and sunshade film for automobiles, and further specifically discloses a preparation method of the sunscreen and sunshade film

Embodiment 1

[0034] Step 1: Heat aluminum to 700°C under vacuum to completely melt to obtain aluminum paste; heat copper and silver at a mass ratio of 20:5 to 1100°C to completely melt under vacuum to obtain composite copper-silver paste;

[0035] Step 2: Preheat nano-glass microspheres with a particle size of 20-50nm to 500°C, and use high-pressure argon to transport the nano-glass microspheres and aluminum slurry to the upper part of the settling chamber through two opposing nozzles at high pressure with a 2MPa airflow. In the upper part of the chamber, the nano-glass microspheres collide with the aluminum paste and disperse. The aluminum paste coats the surface of the nano-glass microspheres, and gradually settles down to cool down. The aluminum-coated nano-glass microspheres are collected at the bottom of the settling chamber; the nano-glass microspheres , The mass ratio of aluminum paste is 100:15;

Abstract

The invention belongs to the technical field of functional films, and particularly relates to a sun-screening and sun-shading film for automobile window glass and a preparation method thereof. The nanometer glass microspheres are coated with aluminum, nanometer glass microspheres are coated with copper and silver, the nanometer glass microspheres are dispersed in PET, and a PET biaxially orientedfilm is prepared, so that the nanometer glass microspheres coated with different metals are dispersed on a upper layer and a lower layer of the film respectively; the surface of the nano glass microsphere is coated with aluminum, reflection and diffuse reflection exist, and reflection of the aluminum metal layer can reflect part of infrared rays and ultraviolet rays in light back; diffuse reflection enables the rest of infrared rays and ultraviolet rays to be absorbed when the ultraviolet light absorber and the infrared light absorber repeatedly diffuse, so that the heat insulation effect is effectively achieved; the surfaces of the nano glass microspheres are coated with copper and silver on the bottom layer, and missed infrared rays and ultraviolet rays are reflected and diffused; furthermore, the metal-coated glass microspheres are dispersed in the PET, so that the problems that light transmission is influenced by aluminizing, an aluminum layer is easy to fall off, a metal coating has strong light reflection and the like are solved.

Description

technical field [0001] The invention belongs to the technical field of functional films, and in particular relates to a sunscreen and sunshade film for automobile window glass and a preparation method. Background technique [0002] Sunlight is composed of ultraviolet rays (200nm-380nm), visible light (380nm-760nm) and infrared rays (760nm-2500nm). Ultraviolet light is an invisible light with a wavelength shorter than visible light. The wavelength range is 280nm-400nm. It has significant chemical effects and is often used for sterilization and disinfection. The sun's rays contain more ultraviolet rays. If exposed to ultraviolet rays for a long time and excessively, it will cause burns to human skin and eyes. Ultraviolet rays can damage human skin cells and cause wrinkles and stains. Infrared rays are fundamental to generating heat in sunlight. While the car is pursuing permeability, it uses a large area of ​​window glass, front glass, sunroof glass, etc., which causes a lot...
