Abstract

The invention relates to a novel broad-breadth sun-shading material which consists of a substrate film, a dielectric film, a metal film, a dielectric film, a VO2-doped film and a dielectric film, wherein the dielectric film, the metal film, the dielectric film, the VO2-doped film and the dielectric film are deposited on the substrate film in sequence. A preparation method of the sun-shading material comprises the following steps of: taking a flexible continuous coil with a thickness of 8 mum and a width of 1000-2500 mm as a substrate; flattening with a guide roller and continuously entering a magnetron sputtering device reaction chamber; vacuumizing the reaction chamber, wherein the vacuum degree is not lower than 2*10-3 Pa; and depositing all the films on a substrate by adopting a vacuum film-coating technology. The sun-shading material simultaneously has the performances of light reducing and shading, and heat insulation.

Description

technical field [0001] The invention relates to a novel wide-width sunshade material and a manufacturing method thereof. Background technique [0002] In recent years, various materials and technologies have been introduced into the field of curtains and sunshade films. Such as thermal insulation materials, which can block outdoor heat from entering in summer and reduce indoor heat loss in winter; light reduction and shading materials can adapt to people's needs for different intensity of light, and solve the problem of insufficient indoor light when sunlight is completely blocked by ordinary sunshade materials. . With the change of consumers' aesthetic concepts and the gradual strengthening of environmental protection awareness, these two new materials are sought after by consumers. [0003] However, the above-mentioned new materials only have one of the properties, and there are no reports on materials that have the properties of light reduction, shading, and heat insula...
