Embodiment 1

[0020] Groups of light-transmitting roller blinds with composite structure for all seasons

[0021] 1. Functional optical film: material optical PET film, thickness 25um, reflectivity 55%, light transmittance 30%, total solar energy blocking rate 73%. UV blocking rate 99%

[0022] 2. Outer protective film: high permeability biaxially stretched PE film, thickness 12um,

[0023] 3. Adhesive for compounding: the thickness of EVA adhesive is controlled between 5um-10um, and the thickness of the film after compound curing is controlled between 4um-5um.

[0024] The composite of the roller blind material adopts a conventional tunnel laminating machine. First, the EVA adhesive is first coated on the coating layer of the functional optical film, dried to remove water, and then the biaxially stretched high-transparent PE film is hot pressed to the functionality The optical film is cooled and rewinded neatly to complete the production of the shutter material. The shutter is a three-layer compos...

Abstract

The invention relates to a shutter material for a transmitting curtain with a flexible composite structure. The shutter material comprises functional optical thin films, a protecting film and adhesive for connecting the various thin films, and preferably, ultra-thin threads which are array at equal or unequal intervals are further disposed among the thin films. The shutter material can effectively isolate ultraviolet light and infrared light, is high in visible light transmittance, and overcomes the shortcoming that a conventional shutter for a curtain is light-tight. In addition, the tensile strength can be improved by means of compounding the ultra-thin threads into the shutter material, and the shutter material is more suitable for manufacturing sunshade and lighting products for large-span large buildings without guide tracks.

Description

Technical field [0001] The invention relates to a roller blind material for light-transmitting curtains with a flexible composite structure and a manufacturing method thereof. Background technique [0002] The main function of the roller blind is to isolate it from the outside world and maintain the privacy of the room. At the same time, it is an indispensable decoration. [0003] In modern times, due to the development of science and technology, the curtain material has made a leap forward, and roller blinds made of aluminum alloy, wood chips, and non-woven fabrics have appeared. The common feature is that the material itself does not transmit light, so that the light is completely blocked, resulting in insufficient indoor light, and local lighting needs to be turned on to increase energy consumption; when a part of the roller blind is mechanically opened to make part of the light enter the room, the other part of the light is still blocked , Resulting in uneven distribution of i...
