Description

Technical Field

[0001] The utility model relates to the field of membrane structure materials, in particular to a light and high-strength architectural membrane structure material. Background Art

[0002] Existing PVC architectural membrane structure materials generally use woven or knitted polyester fiber fabric as the base fabric, and use a scraper or magnetic roller to coat PVC on its surface. This type of architectural membrane structure material has low breaking strength, poor impact resistance, high unit area weight, and large thickness. Due to the poor flame retardant performance of polyester fiber, the flame retardant performance of ordinary architectural membrane structure materials is poor. When the breaking strength is greater than 10000N, the weaving of the polyester fiber base cloth becomes difficult, and the thickness of the membrane structure material is also greatly increased. In traditional architectural membrane structure materials with good flame retardant effect, glass fiber woven base cloth is used, and the architectural membrane structure material made of glass fiber as the base cloth has the disadvantages of unhealthy, low tensile breaking strength, poor impact resistance, high unit area weight, and large thickness. In addition, in order to improve the service life of the membrane structure material, it is necessary to use more functional coating materials. However, the use of too much functional coating materials greatly increases the weight of the entire membrane structure material. Therefore, in order to solve the above problems, we propose a lightweight, high-strength flame-retardant polyarylate-based architectural membrane structure material. Summary of the invention

[0003] The purpose of the utility model is to provide a light-weight and high-strength architectural membrane structure material with light weight and high strength in view of the above problems.

[0004] In order to achieve the above-mentioned purpose, the utility model discloses a lightweight and high-strength architectural membrane structure material, including a polyarylate fiber-based fabric layer, the upper and lower sides of the polyarylate fiber-based fabric layer are coated with a PVC resin layer, and the outer sides of the two PVC resin layers are coated with a surface treatment layer. The polyarylate fiber-based fabric layer can effectively improve the mechanical properties and dimensional stability of the membrane structure material, and can make the membrane structure material have excellent heat resistance, weather resistance, chemical resistance and flame retardancy, to a certain extent reduce the use of coating functional materials, and achieve high strength and lightweight membrane structure materials; the PVC resin layer can improve the anti-fouling self-cleaning ability and performance stability of the membrane structure material; the setting of the surface treatment layer can improve the anti-fouling self-cleaning performance, weather resistance and UV resistance of the membrane structure material.

[0005] Preferably, the polyarylate fiber base fabric layer is woven from warp yarns and weft yarns, and the weaving method is single warp single weft plain weave fabric. Compared with double warp double weft, single warp double weft, double warp single weft and other manufacturing methods, the single warp single weft weaving method is simple in manufacturing method and is conducive to reducing the overall weight of the membrane structure material.

[0006] Preferably, the fineness of the warp yarn and the weft yarn are both 500-1000D, and the warp and weft density of the polyarylate fiber base fabric layer are both 25 strands / inch. The warp yarn and the weft yarn adopt the fineness and the warp and weft density of 25 strands / inch, so that a gap is formed between two adjacent warp yarns and two adjacent weft yarns, and then the inner sides of the two PVC resin layers are bonded to each other at the gap, while reducing the overall weight of the membrane structure material, further enhancing the structural strength of the membrane structure material, and further realizing the high strength and lightweight of the membrane structure material.

[0007] Preferably, the membrane structure material has a grammage per square meter of 400-800 GSM and a thickness of 0.3-1.0 mm.

[0008] Preferably, the membrane structure material has a longitudinal breaking strength of 7100-14000 N / 5 cm, and a latitudinal breaking strength of 6900-13800 N / 5 cm.

[0009] Preferably, the PVC resin layer is formed by coating a functional PVC resin material having flame retardant, antistatic and anti-ultraviolet functions on the surface of the polyarylate fiber-based fabric layer by a doctor blade method.

[0010] Preferably, the warp yarns and the weft yarns are both polyarylate fiber filaments.

[0011] Preferably, the polyarylate fiber-based fabric layer is a woven fabric.

[0012] Preferably, the surface treatment layer is polymethyl methacrylate or polyvinylidene fluoride, so that the weather resistance, UV resistance, wear resistance and self-cleaning effect of the membrane structure material are improved.

[0013] In summary, the beneficial effect of the utility model is that coating the PVC resin layer on both sides of the polyarylate fiber-based cloth layer can improve its tensile breaking strength, impact strength and bending resistance while reducing the weight and thickness of the overall membrane structure material, thereby enhancing the safety of use of the membrane structure material and achieving high-strength and lightweight membrane structure materials.
