Description
Technical Field
The invention relates to the technical field of fire-retarding bags, in particular to a fire-retarding bag for electric power as well as a preparation method and application thereof.
Background
To reduce the economic loss caused by fire of wires and cables, fire-retardant packages have been developed. The fire-fighting device has the functions of blocking various cable, penetrating body or hollow and gap of the cable shaft, effectively preventing the diffusion and spreading of flame and smoke when fire occurs, controlling the fire in a certain range and reducing loss. Considering that fire-retarding bags are frequently replaced in use places, the drop resistance and fire resistance of the fire-retarding bags are required to be higher. The requirement on fire resistance is particularly characterized in that the fire-retarding bag needs to have high fire resistance (more than or equal to 3.00 h); the fire-retarding bag needs to have anti-falling performance, and is characterized in that the fire-retarding bag falls freely from a position with the height of 5 meters, and the bag body is not damaged.
In a fire disaster, the outer layer fabric of the traditional fire retardant bag is easy to ablate, and after the filler in the fire retardant bag overflows, the fire retardant layer is easy to collapse, so that a fire source and hot air cannot be completely blocked. According to analysis, the fire resistance temperature of the traditional fire-retardant bag fabric is about 600 ℃, and the temperature in a fire disaster reaches 700 ℃ and above, so that the phenomenon of collapse of the fire-retardant bag easily occurs during high-temperature combustion. In order to achieve better fireproof effect, the practical application will increase the plugging thickness of the fire-retardant bag, and the use cost will also increase.
Based on the above, there is a need to develop a new fire-retarding bag with low cost, ablation resistance, long fire-retarding time and other comprehensive properties.
Disclosure of Invention
The first technical problem to be solved by the invention is as follows:
a firestop bag is provided.
The second technical problem to be solved by the invention is as follows:
a method for preparing the fire-retardant bag is provided.
The third technical problem to be solved by the invention is:
the invention also provides a fire-retardant bag for electric power.
In order to solve the first technical problem, the invention adopts the following technical scheme:
the fire-retardant bag comprises the following components in parts by weight:
45-75 parts of fireproof filler;
5-25 parts of heat insulation filler;
12-32 parts of an expansion material;
5-25 parts of fireproof cloth;
2-18 parts of wetting agent.
According to the embodiments of the present invention, one of the technical solutions has at least one of the following advantages or beneficial effects:
the fire-retardant bag has high fire-retardant temperature, the outer layer fabric is not ablated at 700 ℃, and the inner filler is not easy to spill.
According to one embodiment of the invention, the insulating filler comprises at least one of modified porous mullite fibers and modified aluminum silicate fibers.
According to the embodiment of the invention, the fire-retarding bag added with the modified porous mullite fiber has at least one of the following advantages or beneficial effects:
the modified porous mullite fiber improves the high temperature resistance by adding a specific modifier. This means that it can better withstand the heat in high temperature environments, preventing the temperature inside the firestop bag from rising, thus protecting the equipment and structures. The modified porous mullite fiber is modified, so that the physical properties, such as mechanical strength, wear resistance and the like, of the modified porous mullite fiber are improved. This may make the firestop package more durable and better resistant to the effects of external forces. In addition, the modified porous mullite fiber has excellent fireproof performance, can resist the erosion of high temperature and flame, prevent the spread of fire and reduce the damage of the fire to equipment. It can form a barrier against flame intrusion, protecting the components and structures inside the device. Furthermore, the modified porous mullite fiber is internally provided with a non-closed air hole channel, so that the heat insulation property of the fire retardant package can be further improved, and the air hole channel can physically obstruct heat conduction to a certain extent, so that the heat needs to pass through a complex channel path, and the conduction speed is reduced.
According to the embodiment of the invention, the fire-retarding bag added with the modified aluminum silicate fiber has at least one of the following advantages or beneficial effects:
the modified aluminum silicate fiber has excellent heat insulation performance, and can effectively reduce heat conduction, so that the temperature rise speed in the case of fire is reduced, and the fire spreading is delayed. The modified aluminum silicate fiber is not easy to burn at high temperature, has good fire resistance, can reduce the risk of fire spread, and protects the power equipment from damage. The fiber can play a role in reinforcing the structure in the fire-retarding bag, so that the mechanical strength and stability of the material are improved, and the material is prevented from losing efficacy under the condition of fire. In addition, the modified aluminum silicate fiber also has a synergistic effect with the following components in the firestop bag: the modified aluminum silicate fiber, other fireproof fillers and heat insulation fillers form a multi-layer heat insulation barrier, so that the fire spreading speed is reduced together, and the fire resistance of the power equipment is improved; the modified aluminum silicate fiber interacts with the expansion material when a fire disaster occurs to assist the expansion material to release the expansion gas to form a heat insulation expansion layer, so that the fireproof effect of the fire retardant bag is enhanced; the interaction of the modified aluminum silicate fiber, the fireproof cloth and the wetting agent enhances the overall structural strength of the fire retardant package, and meanwhile, the synergistic effect among the components can be promoted through a certain wetting effect to form tighter combination.
According to one embodiment of the invention, the preparation method of the modified porous mullite fiber comprises the following steps: mixing mullite fiber, aluminum-zirconium coupling agent and resol, reacting, adding aramid fiber, calcined alumina, silica sol, sodium hypochlorite, starch and sodium carboxymethyl cellulose, and sintering to obtain the modified porous mullite fiber.
According to one embodiment of the invention, the aramid fiber and mullite fiber may form a mixed structure in the material, thereby improving the mechanical strength and stability of the modified porous mullite fiber. The two fibers may interweave with each other to form a network that helps to resist external forces and maintain the overall structure of the material. The resol resin and the mullite fiber surface undergo a grafting reaction, so that the combination of the fibers and the resin is realized. This helps to enhance the cohesiveness and overall strength of the material, improving the durability of the material. The calcined alumina and the silica sol act synergistically in the material to jointly improve the heat insulation performance and the high temperature resistance. Both alumina and silica sol have thermal insulation properties, and their combination can form a thermal insulation layer, reducing heat conduction. In addition, they interact with other components to promote the formation of pores. Sodium hypochlorite is decomposed during the high temperature sintering process, releasing gas, resulting in the formation of pores. It cooperates with alumina and silica sol to increase the porosity of the material and thus raise the heat insulating performance. Starch and sodium carboxymethyl cellulose are used to adjust the flowability and formability of the material. They may act as binders in the slurry, helping to mix the various ingredients evenly and maintain good formability. The aluminum-zirconium coupling agent chemically bonds with the mullite fiber at the interface, thereby enhancing the cohesiveness between the fiber and other components. This may help to improve the overall strength and structural stability of the material.
According to one embodiment of the invention, in the process of preparing the modified porous mullite fiber, the mass ratio of the mullite fiber to the aluminum-zirconium coupling agent is 100-150:10-15.
According to one embodiment of the invention, in the process of preparing the modified porous mullite fiber, the ratio of the total mass of the mullite fiber and the aluminum-zirconium coupling agent to the mass of the resol is 100-150:10-15.
According to one embodiment of the invention, the mullite fiber, the aluminum zirconium coupling agent and the resole resin are subjected to reaction and then further comprise the step of washing to be neutral and drying, wherein the pH is controlled to be about 7, the drying time is 2-4h, and the drying temperature is 60-80 ℃.
According to one embodiment of the invention, the sintering temperature is 500-1000 ℃ and the sintering time is 4-6 hours in the process of preparing the modified porous mullite fiber.
