Description

Technical Field

[0001] The utility model relates to the technical field of curtain fabrics, in particular to a heat-insulating and flame-retardant curtain fabric. Background Art

[0002] The main function of a curtain is to isolate from the outside world and maintain the privacy of the living room. At the same time, it is an indispensable decoration for home improvement. In winter, the curtain divides the indoor and outdoor into two worlds, adding a warm atmosphere to the room. Ordinary curtain fabrics have the function of shading, but most of the curtain fabrics on the current market cannot effectively inhibit the burning of the curtain fabric in case of a fire. Instead, they will intensify the fire, increasing the difficulty for the victims to escape from the scene.

[0003] Currently, an existing heat-insulating and flame-retardant curtain fabric (such as patent number: CN210174325U) discloses a heat-insulating and flame-retardant curtain fabric, including a base fabric layer. A flame-retardant layer is bonded to one side of the base fabric layer. An insulating layer is bonded to the side of the flame-retardant layer away from the base fabric layer. A waterproof layer is provided on the side of the insulating layer away from the flame-retardant layer. An inner layer is provided on the side of the base fabric layer away from the flame-retardant layer. The beneficial effects of the utility model are as follows: By setting the flame-retardant layer, when a fire breaks out indoors, the flame-retardant layer in the curtain fabric can inhibit the spread of the fire, buying more escape time for the escapees. When the curtain fabric is continuously opened or closed during use, the inner layer of the curtain fabric will get dirty. By separating the hook surface of the magic tape on the base fabric layer from the loop surface of the magic tape on the inner layer, the inner layer can be removed. After cleaning the inner layer, it can be bonded again through the hook surface and loop surface of the magic tape, which is convenient to use and does not require the whole curtain fabric to be cleaned, reducing the labor intensity of cleaning the curtain fabric.

[0004] However, in the process of implementing the above technical solution, it is found that there are at least the following technical problems: The heat-insulating and flame-retardant effect of the existing curtain fabric mainly depends on its use of special fire-resistant and fire-proof materials. For the fabric used for the curtain of this device, even if the flame-retardant effect of the flame-retardant layer and the insulating layer is very good, the silk used for its base fabric layer will slowly melt under high-temperature baking, even if it is not directly ignited, resulting in the whole fabric falling apart and the flame-retardant and heat-insulating effects disappearing. Therefore, there is a large room for improvement in the heat-insulating and flame-retardant effect of the existing curtain fabric. Summary of the Utility Model

[0005] (I) Technical Problems to be Solved

[0006] Aiming at the deficiencies of the prior art, the utility model provides a heat-insulating and flame-retardant curtain fabric, solving the technical problem that the existing device may melt under high-temperature baking, resulting in the failure of the flame-retardant and heat-insulating functions.

[0007] (II) Technical Solutions

[0008] To achieve the above objectives, the present utility model is realized through the following technical solutions:

[0009] A heat-insulating and flame-retardant curtain fabric, comprising a base fabric layer and a high-silica fireproof fabric. The top end of the high-silica fireproof fabric is annular, and a placement groove is formed inside the top ring of the high-silica fireproof fabric. The top end of the high-silica fireproof fabric is fixedly connected to the top end of the base fabric layer.

[0010] Preferably: The base fabric layer and the high-silica fireproof fabric are bonded by glue, and several penetration grooves are provided between the base fabric layer and the high-silica fireproof fabric.

[0011] Preferably: A polyethylene liquid bag is arranged in the placement groove, a phosphorus-based liquid flame retardant is wrapped in the polyethylene liquid bag, and the polyethylene liquid bag is fixedly connected with four heat-conducting metal bolts. The ends of the heat-conducting metal bolts away from the polyethylene liquid bag all penetrate through the high-silica fireproof fabric.

[0012] Preferably: Several magic tape hook surfaces are fixedly connected to the end of the high-silica fireproof fabric away from the base fabric layer. Several modular isolation layers are arranged on the side of the magic tape hook surface away from the high-silica fireproof fabric. A magic tape loop surface is arranged on the side of the modular isolation layer close to the magic tape hook surface, and the magic tape hook surface and the magic tape loop surface are bonded.

[0013] Preferably: The base fabric layer is woven from a composite material combining nylon fiber and metal wire.

[0014] Preferably: The modular isolation layer is made of glass fiber.

[0015] (III) Beneficial effects

[0016] 1. The base fabric layer made of a composite material combining nylon fiber and metal wire will not fall apart quickly even if it melts, and the high-silica fireproof fabric itself has high heat resistance and high melting point, avoiding the problem that the base fabric layer and the high-silica fireproof fabric lose their heat insulation and flame retardant functions due to melting caused by high temperature during a fire. And because there is a polyethylene liquid bag, under the continuous baking of the fire, the heat-conducting metal bolts will be heated. When the temperature of the heat-conducting metal bolts is higher than the melting point of the polyethylene liquid bag, the contact part between the polyethylene liquid bag and the heat-conducting metal bolts will melt, and the phosphorus-based liquid flame retardant wrapped in the polyethylene liquid bag will leak out and enter the penetration grooves under the action of gravity, partially wetting the base fabric layer and the high-silica fireproof fabric, making the flame retardant performance of the base fabric layer and the high-silica fireproof fabric reach the highest, solving the problem that the existing device may melt under high-temperature baking, resulting in the failure of the flame retardant and heat insulation functions.

[0017] Second, the modular isolation layer pasted by the hook surface and loop surface of Velcro has higher transformability. The modular isolation layer can be pasted at the appropriate position according to needs. When a minor fire occurs and only a minor damage occurs to the modular isolation layer of the device body of the present application, the damaged modular isolation layer can be directly removed and a new modular isolation layer can be replaced without replacing the entire device, making the present application environmentally friendly, economical and highly transformable.

[0025] The embodiment of the present application provides a heat-insulating and flame-retardant curtain cloth, effectively solving the problem that the existing device may melt under high-temperature baking, resulting in the failure of the flame-retardant and heat-insulating functions.

[0026] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 shown, the technical solution in the embodiment of the present application effectively solves the technical problem that the existing device may melt under high-temperature baking, resulting in the failure of the flame-retardant and heat-insulating functions. The general idea is as follows:

[0027] In view of the problems existing in the prior art, the utility model provides a heat-insulating and flame-retardant curtain fabric, which comprises a base fabric layer 1 and a high-silica fireproof fabric 2. The top end of the high-silica fireproof fabric 2 is annular, and a placement groove 6 is formed inside the top ring of the high-silica fireproof fabric 2. The top end of the high-silica fireproof fabric 2 is fixedly connected to the top end of the base fabric layer 1.

[0028] The base fabric layer 1 and the high-silica fireproof fabric 2 are bonded by glue, and a plurality of penetration grooves 9 are provided between the base fabric layer 1 and the high-silica fireproof fabric 2.

[0029] A polyethylene liquid bag 7 is arranged in the placement groove 6. A phosphorus-based liquid flame retardant is wrapped in the polyethylene liquid bag 7. The polyethylene liquid bag 7 is fixedly connected with four heat-conducting metal bolts 8, and one end of each heat-conducting metal bolt 8 far away from the polyethylene liquid bag 7 penetrates through the high-silica fireproof fabric 2.

[0030] One end of the high-silica fireproof fabric 2 far away from the base fabric layer 1 is fixedly connected with a plurality of magic tape hook surfaces 3. A plurality of modular isolation layers 5 are arranged on one side of the magic tape hook surface 3 far away from the high-silica fireproof fabric 2. A magic tape loop surface 4 is arranged on one side of the modular isolation layer 5 close to the magic tape hook surface 3, and the magic tape hook surface 3 and the magic tape loop surface 4 are bonded.

[0031] The base fabric layer 1 is woven from a composite material combining nylon fiber and metal wire.

[0032] The modular isolation layer 5 is made of glass fiber.

[0033] The base fabric layer 1 made of a composite material combining nylon fiber and metal wire will not fall apart quickly even if it melts. Moreover, the high-silica fireproof fabric 2 itself has high heat resistance and a high melting point, avoiding the problem that the base fabric layer 1 and the high-silica fireproof fabric 2 lose their heat insulation and flame retardant functions due to melting caused by high temperature during a fire. And because the polyethylene liquid bag 7 is provided, under the continuous baking of the fire, the heat-conducting metal bolts 8 will be heated. When the temperature of the heat-conducting metal bolts 8 is higher than the melting point of the polyethylene liquid bag 7, the contact part between the polyethylene liquid bag 7 and the heat-conducting metal bolts 8 will melt, and the phosphorus-based liquid flame retardant wrapped in the polyethylene liquid bag 7 will leak out and enter the penetration grooves 9 under the action of gravity, partially wetting the base fabric layer 1 and the high-silica fireproof fabric 2, so that the flame retardant performance of the base fabric layer 1 and the high-silica fireproof fabric 2 reaches the highest, solving the problem that the existing device may melt under high-temperature baking, resulting in the failure of the flame retardant and heat insulation functions.

[0034] Working principle:

[0035] First step, in case of a fire, if the fire is located on one side of the modular isolation layer 5, due to the material properties of the modular isolation layer 5, it can play a role in isolating fire, separating the fire from the high-silica fiber fireproof cloth 2. And because of the setting of the hook surface 3 of the magic tape and the loop surface 4 of the magic tape, there is a large gap between the modular isolation layer 5 and the high-silica fiber fireproof cloth 2. This gap can play a large heat insulation effect, and the remaining heat is blocked by the body of the high-silica fiber fireproof cloth 2, so that the temperature of the fire conducted to the base cloth layer 1 is always lower than its melting point. And because the base cloth layer 1 is made of a composite material combining nylon fiber and metal wire, even if it melts, it will not fall apart quickly. The modular isolation layer 5, the high-silica fiber fireproof cloth 2, the base cloth layer 1, and the gap between the high-silica fiber fireproof cloth 2 and the modular isolation layer 5 play the function of heat insulation and fire prevention in the first stage.

[0036] Second step, under the continuous baking of the fire, the heat-conducting metal bolt 8 will be heated. When the temperature of the heat-conducting metal bolt 8 is higher than the melting point of the polyethylene liquid bag 7, the contact part between the polyethylene liquid bag 7 and the heat-conducting metal bolt 8 will melt, and the phosphorus-based liquid flame retardant wrapped in the polyethylene liquid bag 7 will leak out. Under the action of gravity, it will enter the penetration tank 9 and partially infiltrate the base cloth layer 1 and the high-silica fiber fireproof cloth 2, so that the flame retardant properties of the base cloth layer 1 and the high-silica fiber fireproof cloth 2 reach the highest level.

[0037] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, and are not limitations on the implementation modes. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation modes here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
