Description

Technical Field

[0001] This invention relates to the field of fiberglass cloth technology, and in particular to a temperature-resistant and flame-retardant fiberglass cloth. Background Technology

[0002] Temperature-resistant and flame-retardant fiberglass cloth is a functional material based on fiberglass weaving, which undergoes special treatment to enhance its high-temperature resistance and fire resistance. It has applications in construction and engineering, industrial protection, transportation, and energy and power industries.

[0003] (1) When improving the flame retardant properties of heat-resistant and flame-retardant fiberglass cloth, a high-temperature heat insulation layer is generally formed on the surface of the fiberglass base cloth. This does not change the heat insulation and flame retardant nature of the base cloth. Once the surface layer falls off, the flame retardant effect will be reduced.

[0004] (2) Existing fiberglass cloth can withstand high temperatures of 600℃ and can maintain the integrity of its shape and structure at high temperatures. However, when encountering higher temperatures, fiberglass cloth cannot achieve the effect of high temperature resistance, which reduces the applicable range of fiberglass cloth.

[0005] (3) When fiberglass cloth is connected to adjacent layers, pressure-sensitive adhesive is generally used for direct bonding. However, the pressure-sensitive adhesive has poor effect and is not resistant to high temperature, making the two layers easily dispersed. Utility Model Content

[0006] In order to solve one or more technical problems existing in the prior art, the purpose of this application is to provide a temperature-resistant and flame-retardant fiberglass cloth that can improve the temperature resistance and flame-retardant effect of fiberglass cloth.

[0007] To address the aforementioned technical problems, one of the objectives of this application is achieved through the following technical solution: A heat-resistant and flame-retardant fiberglass cloth includes a fiberglass cloth, a heat-resistant layer fixedly provided on the top of the fiberglass cloth, a connecting layer fixedly provided on the bottom of the fiberglass cloth, a heat insulation layer fixedly provided on the bottom of the connecting layer, and the heat insulation layer is fixedly disposed on the fiberglass cloth through the connecting layer. The heat insulation layer includes a base cloth with a loose body and pores on the surface and inside, and vermiculite particles filled in the base cloth.

[0008] Furthermore, the fiberglass cloth is electronically graded.

[0009] Furthermore, the heat-resistant layer is formed by drying and sintering a polytetrafluoroethylene emulsion.

[0010] Furthermore, the base fabric is made of glass fiber bulked fabric.

[0011] Furthermore, the connecting layer is a PTFE membrane.

[0012] Furthermore, an anti-slip layer is provided at the bottom of the heat insulation layer.

[0013] Furthermore, the anti-slip layer is made of silicone.

[0014] Furthermore, an adhesive layer is fixedly provided at the bottom of the heat insulation layer.

[0015] Furthermore, the adhesive layer is made of pressure-sensitive adhesive.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) The fiberglass bulked cloth is loose and has many pores on its surface and inside. After being impregnated and dried in vermiculite emulsion, the vermiculite particles will be embedded in the pores of the bulked cloth and can fully combine with the bulked cloth. The fiberglass cloth can withstand a high temperature of 600℃ and can maintain the integrity of its shape and structure at high temperatures. Attached Figure Description

Detailed Implementation

[0018] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0019] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0020] The terms "first," "second," etc., used in this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class, not limited in number; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the preceding and following objects.

[0021] Example 1: As Figure 1 As shown, this embodiment provides a heat-resistant and flame-retardant fiberglass cloth, which includes a fiberglass cloth 1. A heat-resistant layer 4 is fixedly provided on the top of the fiberglass cloth 1. The heat-resistant layer 4 is a coated polytetrafluoroethylene emulsion. In use, electronic grade fiberglass cloth 1 is selected, and one side surface is uniformly coated with polytetrafluoroethylene emulsion. Then, it is dried and sintered at 300-350℃, so that the heat-resistant layer 4 can be better fixed on the fiberglass cloth 1. Polytetrafluoroethylene is a polymer compound formed by the polymerization of tetrafluoroethylene. It has excellent chemical stability, corrosion resistance, sealing performance, high lubricity and non-stickiness, electrical insulation and good anti-aging resistance. Polytetrafluoroethylene can work for a long time in the temperature range of -196℃ to +250℃, showing excellent temperature resistance.

[0022] Furthermore, a connecting layer 2 is fixedly provided at the bottom of the fiberglass cloth 1, and a heat insulation layer 3 is fixedly provided at the bottom of the connecting layer 2. The heat insulation layer 3 is fixedly set on the fiberglass cloth 1 through the connecting layer 2. The heat insulation layer 3 includes a fiberglass bulked cloth, and vermiculite material is provided on the outer surface of the fiberglass bulked cloth. Using fiberglass bulked cloth as the matrix, the fiberglass bulked cloth is fully impregnated in vermiculite emulsion, and then dried at 120-150℃ to produce vermiculite-fiberglass bulked cloth. The fiberglass bulked cloth is fluffy and has many pores on its surface and inside. After impregnation and drying in vermiculite emulsion, vermiculite particles will be embedded in the pores of the bulked cloth, allowing for full bonding with the bulked cloth. Fiberglass cloth 1 can withstand high temperatures of 600℃ and maintain its shape and structure integrity even at high temperatures, preventing it from falling off the fiberglass cloth. Compared with existing technologies, it solves the technical problem that forming a high-temperature resistant heat insulation layer on the surface of the fiberglass base cloth does not change the heat insulation and flame retardant nature of the base cloth. Once the surface layer falls off, the flame retardant effect will be reduced.

[0023] Vermiculite has low thermal conductivity, which slows down heat transfer under high temperatures or flames. It also has good thermal stability, maintaining its shape and structural integrity even at temperatures of 800-1000℃. Furthermore, vermiculite expands at high temperatures, increasing its volume to form the insulation layer 3, further reducing heat transfer and achieving a flame-retardant effect. In summary, by incorporating the insulation layer 3 and the heat-resistant layer 4, the heat resistance and flame-retardant effect of the fiberglass cloth 1 can be improved, resulting in a wider range of high-temperature applications. Compared to existing technologies, this solves the technical problem that fiberglass cloth cannot achieve high-temperature resistance in situations with even higher temperatures, thus reducing its applicability.

[0024] Furthermore, the fiberglass cloth is electronically graded, making it even more compatible.

[0025] Furthermore, the connecting layer 2 is a PTFE membrane, which is used to hot-press the heat insulation layer 3 and the fiberglass cloth 1 together. The PTFE membrane is a microporous film made from polytetrafluoroethylene through special processes such as extrusion and biaxial stretching. It has a fibrous microporous structure with a porosity of over 85%, approximately 1.4 billion micropores per square centimeter, and a pore size range of 0.02μm-15μm. Its performance advantages include unique nodal fibrillation, smooth surface, chemical resistance, air permeability but water impermeability, high porosity, flame retardancy, high temperature resistance, resistance to strong acids and alkalis, and non-toxicity. This eliminates the need for pressure-sensitive adhesives for hot-press bonding. The PTFE membrane is heat-resistant and the bond is less prone to dispersion. Compared to existing technologies, this solves the technical problem of poor performance and easy dispersion of the two layers when fiberglass cloth is bonded to adjacent layers using pressure-sensitive adhesives, which are generally ineffective and not heat-resistant.

[0026] Furthermore, an anti-slip layer 5 is fixedly installed at the bottom of the insulation layer 3. The anti-slip layer 5 is made of silicone. The silicone layer provides an anti-slip function and can be directly laid on the ground to provide an anti-slip effect.

[0027] Example 2: The only difference between this example and Example 1 is that an adhesive layer 6 is fixedly provided at the bottom of the heat insulation layer 3. The adhesive layer 6 is made of pressure-sensitive adhesive, which can serve as a bonding agent and can be directly laid on the ground. Pressure-sensitive adhesive is an adhesive that can achieve bonding with only slight pressure without heating, solvents, or other special treatments. It is widely used in tapes, labels, medical products, and other fields. Its core characteristics include adhesive properties such as peel strength, cohesive strength, and adhesion strength, as well as functional indicators such as temperature resistance, flame retardancy, and aging resistance.

[0028] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
