DETAILED DESCRIPTION

[0015] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] Embodiment 1

[0017] Combination Figure 1 , this embodiment is described in detail. The environmentally friendly foamed coated shading cloth involved in this embodiment includes a bonded base fabric layer 1, an environmentally friendly foaming layer 2, a TPU black shading film layer 3 and an anti-ultraviolet fabric layer 4; the base fabric layer 1 is compounded with a jacquard flame-retardant fabric layer 5 on one side away from the environmentally friendly foaming layer 2. The jacquard flame-retardant fabric layer 5 can not only provide a good flame-retardant effect, but also because it is a jacquard fabric, the pattern can be designed according to actual needs, so that the fabric can provide a beautiful pattern. The layers are compounded by flame-retardant hot melt adhesive.

[0018] Furthermore, the base fabric layer 1 is interwoven with flame-retardant composite yarns, and the flame-retardant composite yarns include a core yarn and a coating layer coated on the outside of the core yarn, the core yarn is a PTFE split film filament, and the coating layer is a polyacrylonitrile pre-oxidized silk fiber. Since the PTFE split film filaments are made of polytetrafluoroethylene, they have good shape retention when used, especially when heated, which can also make the fabric have good dimensional stability and reduce its deformation. And the polyacrylonitrile pre-oxidized silk fiber used has a high oxygen limiting index, so that together with the jacquard flame-retardant fabric layer 5, the blackout cloth has a good flame retardant effect.

[0019] Furthermore, the jacquard flame-retardant fabric layer 5 is formed by interweaving flame-retardant warp yarns and flame-retardant weft yarns according to a jacquard weave, wherein the flame-retardant warp yarns are flame-retardant polyester filaments, and the flame-retardant weft yarns are flame-retardant viscose fiber yarns. The color of the flame-retardant polyester filaments used can be selected according to the pattern of the jacquard weave.

[0020] Furthermore, the environmentally friendly foaming layer 2 is made of water-based foaming material, which has good environmental protection, and is specifically made of water-based polyurethane foaming material.

[0021] Further, the TPU black light-shielding film in the TPU black light-shielding film layer 3 is formed by uniformly mixing 30 parts of polyurethane, 8 parts of low-density polyethylene, 20 parts by mass of carbon black, 30 parts by mass of opalescent agent, 8 parts by mass of titanium dioxide, 10 parts of nano-gelatin microbeads, and 5 parts of phenyl salicylate, and then extruding and blow-molding. The obtained parts are parts by mass. The nano-gelatin microbeads used are nano-gelatin microspheres, and their particle size is 150 nanometers.

[0022] Furthermore, the anti-ultraviolet fabric layer 4 includes a fabric layer interwoven with anti-ultraviolet polyester and a titanium dioxide coating attached to the fabric layer. The titanium dioxide coating has a good anti-ultraviolet effect.

[0023] Embodiment 2

[0024] Combination Figure 2 , this embodiment is described in detail. The environmentally friendly foam coating shading cloth involved in this embodiment is different from the embodiment 1 in that: the side of the anti-ultraviolet fabric layer 4 close to the TPU black shading film layer 3 is compounded with a microporous membrane 6. The specific microporous membrane used is a PTFE microporous membrane, so that the shading fabric has a good waterproof effect. Specifically, it can be compounded with a hot melt adhesive.

[0025] Another difference from the first embodiment is that a polyimide fiber / TiO2-SiO2 composite aerogel layer 7 is provided between the environmentally friendly foam layer 2 and the base fabric layer 1 through a flame-retardant hot melt adhesive. The performance of the fire-retardant roller curtain fabric involved in this embodiment in blocking external heat can be improved, and the exchange of indoor and outdoor heat can be reduced, thereby enhancing the indoor temperature maintenance capability.

[0026] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
