Description

Technical Field

[0001] The present application relates to the technical field of fireproof roller shutters, and in particular to a fireproof roller shutter having basalt fibers. Background Art

[0002] At present, fireproof roller shutters are mainly used in places that require fire separation, especially walls that require larger openings for production and use but cannot be equipped with fire doors, such as industrial buildings, factories and warehouses, civil buildings, large shopping malls, underground projects, high-end hotels, libraries, theaters, public buildings, stations, and large exhibition halls.

[0003] At present, the traditional fireproof rolling shutter doors used in the building fire protection industry have flexible inorganic curtain surface basic raw materials, which are composed of at least two layers of fire-resistant fabric on the outer layer and the inner layer of heat-insulating sandwich material with an intermediate lining layer. The thickness of the outer layer of fire-resistant fabric is ≥3.0mm, and the unit area mass is ≥1500g / m2; the thickness of the inner layer of heat-insulating sandwich material is ≥18mm, and the volume density is ≥150kg / m3. Additional load-bearing components are set in the vertical direction inside the curtain surface, and reinforced plywood is set in the horizontal direction of the surface, and the interval is ≤400mm; in its manufacturing technology, fire-resistant fiber cloth, mineral wool or aluminum silicate fiber, and metal plywood materials are used. Its disadvantages are that the basic raw materials of the curtain surface are heavy, thick, and have high energy consumption and operating noise, which leads to large occupation of building space, and there are problems such as low industrial energy efficiency, high structural energy consumption, and unsightly appearance. Summary of the invention

[0004] In order to make the fireproof roller shutter have a good fireproof rating and a lightweight property at the same time, the present application provides a fireproof roller shutter with basalt fiber.

[0005] The fireproof roller shutter with basalt fiber provided in the present application adopts the following technical solution:

[0006] A fireproof roller shutter with basalt fiber cloth, comprising a fireproof roller shutter cloth, the fireproof roller shutter cloth is arranged in multiple layers, the thickness of the fireproof roller shutter cloth is less than or equal to 0.5 mm, the fireproof roller shutter cloth comprises a fireproof heat insulation layer, the fireproof heat insulation layer is formed by interweaving and blending basalt fiber and aluminum silicate refractory fiber, and the thickness of the fireproof heat insulation layer is 0.1 mm to 0.3 mm;

[0007] The fireproof roller curtain fabric also includes a fire-receiving surface layer and a heat-radiation protection layer. The fire-receiving surface layer is combined with the fire-proof heat-insulating layer. The side of the fire-proof heat-insulating layer away from the fire-receiving surface layer is combined with the heat-radiation protection layer. The fire-receiving surface layer, the fire-proof heat-insulating layer and the heat-radiation protection layer are all combined by a fire-proof adhesive. The thickness of the fire-receiving surface layer and the heat-radiation protection layer are both 0.1 mm to 0.3 mm.

[0008] Preferably, the basalt yarn is formed by twisting basalt fibers, the diameter of the basalt fibers is 9-13 μm, and the fineness of the basalt yarn is 60-80 tex.

[0009] Preferably, the aluminum silicate refractory yarn is formed by twisting aluminum silicate fibers, the diameter of the aluminum silicate fibers is 20-35 μm, and the fineness of the aluminum silicate yarn is 30-45 tex.

[0010] Preferably, the spinning process of the aluminum silicate yarn is: opening, carding, drawing, and friction spinning. The aluminum silicate fiber is cut during the carding process, and the length after cutting is 30-40 mm.

[0011] The process parameters of the carding machine are: licker-in speed: 630-700r / min, cover speed: 80-100r / min.

[0012] Preferably, the warp yarns of the fireproof roller curtain fabric are the basalt yarns, the weft yarns of the fireproof roller curtain fabric are the aluminum silicate yarns, and the fabric structure of the fireproof roller curtain fabric is a plain weave.

[0013] By adopting the above technical scheme, interweaving and blending can effectively maintain the structural stability of the fireproof roller shutter cloth under high temperature and flame, and effectively prevent the spread of fire. At the same time, aluminum silicate refractory fiber has the characteristics of low thermal conductivity and small heat loss, and basalt fiber also has good thermal insulation. After the two are interwoven and blended, the thermal insulation effect of the fireproof roller shutter cloth is more prominent, which can significantly reduce the transfer of heat to the back of the fire and reduce the threat of fire to the surrounding environment. Furthermore, basalt fiber has the advantages of high strength and no thermal shrinkage, and aluminum silicate refractory fiber also has good tensile strength and wear resistance. The fireproof roller shutter cloth after interwoven and blended has higher durability and strength, and can maintain stable fireproof performance during long-term use.

[0014] Furthermore, the fireproof roller shutter cloth is reasonably layered. The fire-exposed surface layer is used to directly face the fire source, the fireproof and heat-insulating layer plays a role in blocking heat, and the radiation-proof layer is used to reduce the radiation propagation of heat. This allows the fireproof roller shutter cloth to effectively block the spread of fire, reduce the transfer of heat to the back-fire surface, and enhance the stability and durability of the fireproof roller shutter cloth.

[0018] The following is combined with Figure 1-2 This application is described in further detail.

[0019] The present application embodiment discloses a fireproof roller shutter with basalt fiber cloth. Figure 1 and Figure 2 The fireproof roller curtain cloth 1 is arranged in multiple layers, and the thickness of the fireproof roller curtain cloth 1 is less than or equal to 0.5 mm. The fireproof roller curtain cloth 1 includes a fireproof and heat-insulating layer 3, which is formed by interweaving and blending basalt fiber and aluminum silicate refractory fiber. The thickness of the fireproof and heat-insulating layer 3 is 0.1 mm to 0.3 mm.

[0020] Interwoven blending can effectively maintain the structural stability of the fireproof roller shutter cloth 1 under high temperature and flame, and effectively prevent the spread of fire. At the same time, aluminum silicate refractory fibers have the characteristics of low thermal conductivity and small heat loss, and basalt fibers also have good thermal insulation properties. After the two are interwoven and blended, the thermal insulation effect of the fireproof roller shutter cloth 1 is more prominent, which can significantly reduce the transfer of heat to the back-fire surface and reduce the threat of fire to the surrounding environment. Furthermore, basalt fibers have the advantages of high strength and no thermal shrinkage, and aluminum silicate refractory fibers also have good tensile strength and wear resistance. The fireproof roller shutter cloth 1 after interwoven blending has higher durability and strength, and can maintain stable fireproof properties during long-term use.

[0021] The fireproof roller curtain cloth 1 also includes a fire-exposed surface layer 2 and a heat-radiation protection layer 4. The fire-exposed surface layer 2 is combined with the fireproof heat-insulating layer 3. The side of the fireproof heat-insulating layer 3 away from the fire-exposed surface layer 2 is combined with the heat-radiation protection layer 4. The fire-exposed surface layer 2, the fireproof heat-insulating layer 3 and the heat-radiation protection layer 4 are all combined by a fireproof adhesive. The thickness of the fire-exposed surface layer 2 and the heat-radiation protection layer 4 are both 0.1 mm to 0.3 mm.

[0022] As an example, the fireproof rolling curtain fabric 1 has a length of 300 cm and a width of 300 cm.

[0023] As an example, the thickness of the fireproof and heat-insulating layer 3 is 0.3 mm, and the thickness of the fire-exposed surface layer 2 and the heat radiation protection layer 4 are both 0.1 mm.

[0024] As another example, the thickness of the fireproof and heat-insulating layer 3 is 0.1 mm, and the thickness of the fire-exposed surface layer 2 and the heat-radiation protection layer 4 are both 0.1 mm.

[0025] The basalt yarn is twisted from basalt fibers, the diameter of the basalt fibers is 9-13 μm, and the fineness of the basalt yarn is 60-80 tex.

[0026] The aluminum silicate refractory yarn is formed by twisting aluminum silicate fibers, the diameter of the aluminum silicate fibers is 20-35 μm, and the fineness of the aluminum silicate yarn is 30-45 tex.

[0027] The spinning process of aluminum silicate yarn is: opening, carding, drawing, friction spinning. During the carding process, the aluminum silicate fiber is cut to a length of 30-40 mm. The process parameters of the carding machine are: licker-in speed: 630-700 r / min, cover speed: 80-100 r / min.

[0028] The warp yarn of the fireproof rolling curtain cloth is basalt yarn, the weft yarn of the fireproof rolling curtain cloth is the aluminum silicate yarn, and the fabric structure of the fireproof rolling curtain cloth is plain weave so as to have higher tearing strength.

[0029] Compared with the traditional fireproof rolling curtain cloth, the fireproof rolling curtain cloth 1 of this embodiment has the advantages of being light and thin, which not only saves the installation space of the fireproof rolling curtain and facilitates the installation of the fireproof rolling curtain; and in an emergency, the light and thin fireproof rolling curtain cloth 1 can be pulled up or put down more quickly. In addition, the manufacture of the light and thin fireproof rolling curtain cloth 1 generally requires relatively less materials, thereby effectively reducing the material cost.

[0030] The fireproof roller shutter 1 is rationally layered, the fire-exposed surface layer 2 is used to directly face the fire source, the fireproof heat-insulating layer 3 plays a role in blocking heat, and the radiation-proof layer is used to reduce the radiation propagation of heat, so that the fireproof roller shutter 1 can effectively block the spread of fire, reduce the transfer of heat to the back-fire surface, and enhance the stability and durability of the fireproof roller shutter 1.

[0031] According to the national standard GB-14102-2005 test, the fire resistance limit of fireproof rolling curtain fabric 1 is greater than or equal to 3h, and the smoke leakage of the curtain surface is less than or equal to 0.2m 3 / (m 2 ×min).
