Description

Technical Field

[0001] The utility model relates to a fireproof and flame-retardant rolling curtain fabric, belonging to the technical field of textile fabrics. Background Art

[0002] Roller curtains must have basic functions such as blocking solar radiation, blocking heat, lowering indoor temperature, saving indoor light illumination, and preventing glare, so it is very important to select the fabrics for roller curtains. With the development of the fabric industry, more roller curtain fabrics have flooded into the market. And as people's requirements for roller curtain fabrics become higher and higher, the requirements for roller curtain fabrics are getting higher and higher. In particular, people are paying more and more attention to safety, and indoor decorative fabrics are also required to have good flame retardant effects. However, the existing flame retardant fabrics have poor dimensional stability at high temperatures. How to prepare a fire-retardant roller curtain fabric with dimensional stability has become a problem to be solved. Utility Model Content

[0003] The utility model aims to provide a fireproof and flame-retardant rolling curtain fabric, which has good dimensional stability while having fireproof and flame-retardant effects.

[0004] In order to solve the above technical problems, the purpose of the utility model is achieved as follows:

[0005] The utility model relates to a fireproof and flame-retardant roller shutter fabric, comprising a flame-retardant fabric layer, a base fabric layer, a TPU black shading film layer, a heat-insulating fabric layer and an anti-ultraviolet fabric layer which are arranged in sequence and compounded by a flame-retardant adhesive; the flame-retardant fabric layer is interwoven with PTFE composite flame-retardant yarns, and the PTFE composite flame-retardant yarns include parallel-twisted PTFE split film filaments and polyacrylonitrile pre-oxidized silk fiber yarns; the heat-insulating fabric layer is a polyimide fiber / TiO2-SiO2 composite aerogel layer; the base fabric layer is a flame-retardant polyester fabric.

[0006] On the basis of the above scheme and as a preferred scheme of the above scheme: the base fabric layer is fluorescent yellow intrinsic flame-retardant polyester double-line twill.

[0007] On the basis of the above scheme and as a preferred scheme of the above scheme: the anti-ultraviolet fabric layer is interwoven with anti-ultraviolet polyester.

[0008] On the basis of the above scheme and as a preferred scheme of the above scheme: an electroplated aluminum film is arranged on the surface of one side of the anti-ultraviolet fabric layer close to the heat-insulating fabric layer.

[0009] On the basis of the above scheme and as a preferred scheme of the above scheme: the surface of the side of the UV protection fabric layer away from the heat insulation fabric layer is compounded with a PTFE microporous membrane.

[0010] The beneficial effects of the utility model are as follows: the fireproof and flame-retardant roller blind fabric of the utility model uses PTFE split film filaments to make the flame-retardant fabric layer have good dimensional stability, and the use of the TPU black light-shielding film layer provides the fabric with good light-shielding effect and anti-peeping effect. The use of the heat-insulating fabric can improve the heat-insulating performance and thermal insulation effect of the roller blind fabric, and the use of the anti-ultraviolet fabric layer can increase the service life.

[0012] Figure 2 It is a schematic structural diagram of the fire-retardant roller shutter fabric involved in the second embodiment.

[0013] The markings in the figure are as follows: 1-flame retardant fabric layer; 2-base fabric layer; 3-TPU black light-shielding film layer; 4-heat-insulating fabric layer; 5-anti-ultraviolet fabric layer; 6-electroplated aluminum film; 7-PTFE microporous film. DETAILED DESCRIPTION

[0014] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] Embodiment 1

[0016] Combination Figure 1 The fire-retardant rolling curtain fabric involved in this embodiment comprises a flame-retardant fabric layer 1, a base fabric layer 2, a TPU black light-shielding film layer 3, a heat-insulating fabric layer 4 and an anti-ultraviolet fabric layer 5 which are sequentially arranged and compounded by a flame-retardant adhesive.

[0017] The flame retardant fabric layer 1 is interwoven with PTFE composite flame retardant yarns, and the PTFE composite flame retardant yarns include PTFE split film filaments and polyacrylonitrile pre-oxidized silk fiber yarns twisted in parallel. Since the PTFE split film filaments are made of PTFE material, the yarns have good dimensional stability and are not easily deformed when heated, so that the fireproof and flame retardant roller blind fabric has good shape retention. In addition, the polyacrylonitrile pre-oxidized silk fibers used also have a high oxygen limiting index and will not burn when exposed to fire, giving the roller blind fabric a good fire retardant effect.

[0018] The base fabric layer 2 is a flame retardant polyester fabric, specifically a woven fabric interwoven with flame retardant polyester filaments, which gives the roller blind fabric a flame retardant effect. At the same time, the polyester filaments are used to make the base fabric layer 2 have a higher strength. In this embodiment, the base fabric layer 2 is a fluorescent yellow flame retardant polyester double-line twill. The gram weight is selected as 120-180gsm, and the flame retardant performance adopts the ISO-15025 protective clothing flame spread test, the bottom edge burns, smoldering <2s, continued burning <2s, char length <100mm, no melt drops and no holes, airfoil tear strength>50*50, breaking strength>900*600.

[0019] The TPU black light-shielding film in the TPU black light-shielding film layer 3 used is obtained by uniformly mixing 30 parts of polyurethane, 8 parts of low-density polyethylene, 20 parts of carbon black, 30 parts of opalescent agent, 8 parts 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.

[0020] The thermal insulation fabric layer 4 is a polyimide fiber / TiO2-SiO2 composite aerogel layer, which can improve the performance of the fire-retardant roller shutter fabric involved in this embodiment in blocking external heat, reduce the exchange of indoor and outdoor heat, and thus enhance the indoor temperature maintenance ability.

[0021] The anti-ultraviolet fabric layer 5 is a woven fabric made of anti-ultraviolet polyester filaments. When in use, it can block ultraviolet rays from passing through the fabric into the room. First, it can reduce the impact of ultraviolet rays on the room, and then reduce the strong impact of ultraviolet rays on the fabric, slowing down the aging rate of the roller blind fabric and increasing its service life.

[0022] Embodiment 2

[0023] Combination Figure 2 , this embodiment is described in detail. The fire-retardant rolling shutter fabric involved in this embodiment is different from that in the first embodiment in that: an electroplated aluminum film 6 is provided on the surface of the anti-ultraviolet fabric layer 5 on the side close to the heat-insulating fabric layer 4. The provision of the electroplated aluminum film 6 can improve the reflection of the external temperature, thereby further reducing the influence of the external heat on the room.

[0024] Another difference from the first embodiment is that the surface of the anti-ultraviolet fabric layer 5 away from the heat-insulating fabric layer 4 is compounded with a PTFE microporous membrane 7. The use of the PTFE microporous membrane 7 can improve the waterproof effect of the fire-retardant roller shutter fabric and avoid the influence of rain on the interior on rainy days.

[0025] 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.
