Abstract
Description
Technical Field
[0001] The utility model relates to the field of decorative films, in particular to a durable PVC flame-retardant decorative film. Background Art
[0002] PVC film can be used for surface packaging of various panels, has good decorative effect, and is widely used in the fields of packaging, building materials and decorative materials.
[0003] The surface of wooden boards can be covered with PVC film to form decorative materials for buildings or furniture, which accounts for a large proportion of the applications of PVC film. Wooden boards are easily ignited, so the flame retardancy of PVC film is required to be high. In the existing technology, the flame retardancy of PVC film is mostly improved by adding flame retardants. However, the addition of flame retardants has a certain adverse effect on the mechanical properties and weather resistance of PVC film, which needs to be improved. Utility Model Content
[0004] The utility model aims to provide a durable PVC flame-retardant decorative film to enhance the flame-retardant effect and ensure durability.
[0005] To achieve this purpose, the utility model adopts the following technical solutions:
[0006] A durable PVC flame-retardant decorative film comprises: a first PVC film layer, a second PVC film layer, an isolation film layer, a first flame-retardant fiber bundle and a second flame-retardant fiber bundle, wherein the isolation film layer is arranged above the first PVC film layer in a wave-like continuous bending, the second PVC film layer is arranged above the isolation film layer, the top surface of the isolation film layer is provided with first wave valleys at intervals, the first flame-retardant fiber bundles are filled in the first wave valleys, the bottom surface of the isolation film layer is provided with second wave valleys at intervals, the second flame-retardant fiber bundles are filled in the second wave valleys.
[0007] Wherein, the first flame retardant fiber bundle and the second flame retardant fiber bundle are respectively made of polyester flame retardant fiber.
[0008] Wherein, an aluminum-plated reflective layer is arranged on the top surface of the isolation film layer.
[0009] The colors of the first flame-retardant fiber bundles in two adjacent first wave valleys are the same or different.
[0010] Wherein, a first flame retardant adhesive layer is arranged on the top surface of the first PVC film layer.
[0011] Wherein, a second flame retardant adhesive layer is arranged on the bottom surface of the second PVC film layer.
[0012] The beneficial effects of the utility model are: a durable PVC flame-retardant decorative film, which particularly adopts a first flame-retardant fiber bundle and a second flame-retardant fiber bundle to enhance the flame-retardant effect. There is no need to add flame retardants to the first PVC film layer and the second PVC film layer or reduce the addition of flame retardants, which is beneficial to ensure the mechanical properties and weather resistance of the first PVC film layer and the second PVC film layer, and is more durable. In addition, the color setting of the first flame-retardant fiber bundle is flexible, which can enhance the decorative effect. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION
[0014] Combine the following Figure 1 The technical solution of the utility model is further illustrated by specific embodiments.
[0015] like Figure 1 The durable PVC flame-retardant decorative film shown includes: a first PVC film layer 1, a second PVC film layer 2, an isolation film layer 3, a first flame-retardant fiber bundle 4 and a second flame-retardant fiber bundle 5. The isolation film layer 3 is continuously bent in a wavy shape and is arranged above the first PVC film layer 1. In this embodiment, a first flame-retardant adhesive layer 7 is provided on the top surface of the first PVC film layer 1, and the isolation film layer 3 and the first PVC film layer 1 are bonded and fixed by the first flame-retardant adhesive layer 7.
[0016] The second PVC film layer 2 is arranged above the isolation film layer 3. In this embodiment, a second flame retardant adhesive layer 9 is arranged on the bottom surface of the second PVC film layer 2 to bond and fix the isolation film layer 3 to the second PVC film layer 2. The second flame retardant adhesive layer 9 can be made of transparent UV flame retardant glue, which does not affect the color of the isolation film layer 3 below.
[0017] like Figure 1 As shown, the first wave valleys 8 are arranged on the top surface of the isolation membrane layer 3, and the first flame-retardant fiber bundles 4 are filled in the first wave valleys 8. The second wave valleys 6 are arranged on the bottom surface of the isolation membrane layer 3, and the second flame-retardant fiber bundles 5 are filled in the second wave valleys 6. By filling the first flame-retardant fiber bundles 4 and the second flame-retardant fiber bundles 5, the structural stability of the isolation membrane layer 3 is ensured, and the problem of being unable to reset after being compressed and deformed is reduced.
[0018] In this embodiment, the first flame-retardant fiber bundle 4 and the second flame-retardant fiber bundle 5 are respectively made of polyester flame-retardant fiber, which has good flame-retardant effect and long service life. There is no need to add flame retardants to the first PVC film layer 1 and the second PVC film layer 2 or reduce the addition of flame retardants in the first PVC film layer 1 and the second PVC film layer 2, which is beneficial to ensure the mechanical properties and weather resistance of the first PVC film layer 1 and the second PVC film layer 2, and the whole is more durable.
[0019] In addition, the first flame retardant fiber bundles 4 in two adjacent first troughs 8 have the same or different colors, and the decorative effect can be improved by flexibly setting the colors of the first flame retardant fiber bundles 4. The second PVC film layer 2 is a transparent PVC film, which does not affect the display of the color of the first flame retardant fiber bundles 4.
[0020] In this embodiment, an aluminum-plated reflective layer is provided on the top surface of the isolation film layer 3, and the aluminum-plated reflective layer reflects light to increase brightness and enhance the decorative effect of the first flame-retardant fiber bundle 4. The aluminum-plated reflective layer can also block light and enhance barrier properties, thereby avoiding the problem of the plate being exposed to light and enhancing the durability of the packaged object.
