Description
Fireproof Container
Field
[0001] The invention relates to a fireproof container. lii particular, the invention relates to a multi-walled fireproof container.
Background
[0002] During a fire, particularly in large buildings such as airports or shopping malls.
there are typically a number of safety devices in place to localise and minimise the damage caused by fire. Many of these devices are managed by central control units which coordinate sprinkler systems. fire dampers, louvres and other fire safety devices when a lire is detected. However, electrica' or mechanical componenis within control boxes, actuators or sinillar devices arc themselves vulnerable to fire. As such, it is critical that such systems are protected from fire long enough to bring a fire under control or necessitate the escape of individuals trapped within the building.
[0003] Various devices have been used to protect such systems from fire. Typically, these systems involve fire retardant casings containing inturnescent materials, such as barns, which are used as a protective blanket to shield various systems from the heat and flames of a fire.
[0004] In addition to their fire-retardant properties, any device used to shield control systems from fires must also be lightweight and easy to enclose to a range of different sized control boxes as many of these systems are wall mounted.
[0005] A vancty of technologies are known in the art which have been used to deal with this problem. These include the so-called "thermal boxes", for example those sold by Fire Protection Coatings Limited. Such devices rely heavily on the use of inturnescent paints and intumescent materials which expand on heating and give off water in order to maintain the internal temperature of the box close to the boiling point of water. However, there are no devices that can provide effective protection to control systems and the like for a period of up to two hours. For instance, by maintaining an internal temperature of less than 100°C when exposed to a fire of 300°C for two hours and also maintaining an internal temperature of less than 100°C when exposed to a fire 400°C for thirty minutes.
[0006] The invention is intended to overcome or ameliorate some or all of the above problems.
Summary
[0007] There is provided in a lirst aspect of the invention, a fireproof container comprising one or more walls, wherein the walls comprise a plurality ol layers including: a first outer layer of a first synthetic fiber insulating material: a second inner layer adjacent the first layer, the second layer comprising one or more regions of a second synthetic fibre insulating material and one or more regions of intumescent material; and a third layer, positioned between the first and second layers, comprising a fire resistant material.
[0008] It has surprisingly been found by the inventors that incorporating a synthetic fiber insulating material into the wall of a container as an outer layer leads to a significant improvement in heat resistant properties compared to existing systems.
Containers making use of this construction have been found by the inventors to maintain an internal temperature of 100°C or less when the container is exposed to a fire of 300°C for at least two hours. Many existing fireproof boxes,fail to provide this duration of thermal protection, and where it has been achieved, this is on'y using complex and cxpensive designs. Further, where fireproof containers use synthetic fiber insulating materials, this is present as an internal insulating material, and not as a "Iront line" lire protection material. Therefore, the container dilTers from established systems as the synthetic fiber insulating material is on the outside of the container, fulfilling both a fire barrier and heat insulation function.
[0009] The walls of the lireproof box may contain more than three ayers and additional layers may be interspersed between the first, seconds and third layers to improve the insulating properties of the device. However, it is typically the case that the first layer and third layer of the fire proof container are directly adjacent one another. It is also often the case that the second layer and third layer are directly adjacent one another.
[0010] As used herein the term "directly adjacent" is intended to mean that the first and second (or other) layers are positioned next to one another, without an intentional gap, space or interleaving layer between. The layers may be joined to one another using methods such as by g'uing. mechanical retention (such as tacking. stapling.
etc.), lamination. combinations thereof, or other means, but this is not essential in order for the two layers to be "directly adjacent" as defined herein. Where the layers are joined to one another this can help to reduce movement of the layers relative to one another which is desirable as this could reduce the effectiveness of the container.
However, in many constructions of the container such joining will not he required.
[0011] The term walls' as used herein is intended to refer to each of the sides of the container when assembled not just those sides being substantially vertical. For instance, in a container of "box" (cuboid) construction, the bottom, four vertical sides and top of the "box" are each intended to be interpreted as walls' of the container, the walls are therefore any external face of the container, regardless of the overall shape of the container.
[0012] The fireproof container is intended for use with a range of control boxes and other devices requinng protection from fire. As many of these devices are wall mounted, it is desirable to minimise the weight of the fireproof container in order to assist with fixing of the container to a wall mounted device.
[0013] Usually, the second layer comprises two regions of synthetic fibre insulating material and two regions of intumescent material. Each of the regions of synthetic fibre insulating material may he positioned on opposite sides of the container to one another. Further, each of the regions of intumescent material may also be positioned on opposite sides of the container to one another. Typically, each of the regions of synthetic fiber insulating material are positioned on opposite sides of the container to one another.
[0014] The synthetic fiber insulating material typically comprise one or more polymers and the polymers typically include one or more polyamines.
[0015] Often the polyamide is an aromatic polyamide and may he selected from: poly-para-phenylene terephlthalamide. poly-rneta-phenylene isophthalarnidc or combinations thereof. Typically, the polymer is poly-meia-phenylene isophthalainide.
[0016] The synthetic fiber insulating material typically comprises a polysilicic acid which may comprise 85-99 wt% Sift and 1-10 wt% A1203.
[0017] In one example, the synthetic fiber insulating material comprises a polyamide and a polysilicic acid as described herein. The inventors have found that by combining these materials together, it is possible to make a material which is both lightweight and demonstrates excellent insulating properties. Usually the ratio of polyarnide to polysilicic acid is in the range of 5:1 and 1:5. However, it may be the case that the ratio of polyamide to polysilicic acid is in the range of 1:1 and 1:4 and it may he the case that the ratio is 2:5 and 2:7.
[0018] Further, it is typically the case that the synthetic fiber insulating material consists essentially of 25% poly-meea-phenylene isophthalamide and 75% polysilicic acid comprises 85-99 wt% Sift and 1-10 wt% A1203. The synthetic liher insulating material used in thc first layer of the container may be FabBloc 45A Insulating Fabric.
The synthetic fiber insulating material used in the second layer of the container may be FabBloc Plain hisulating Fabric. The difference between FabBloc 45A and FabBloc plain is that FahBloc 45A includes a fire rcsistant coating of chemical coating Fahshield LP 1205 (RTM).
[0019] By combining these two insulating materials together (pol y-meta-phenylene isophthalamide and polysilicic acid), this provides an extremely light weight and efficient insulation layer. This technology is conventionally used in the insulation of aircraft fuselages to retain heat. When applied to the fire proof containers, this allows for containers to be made that are not only light weight but that can also provide enhanced fire protection.
[0020] Alternatively, the synthetic fiber insulating material may comprise 90% - 100% poly-meta-phenylene isophthalamide. Further, the synthetic fiber insulating material may he a needlefelt, and typically a non-woven, material. The synthetic fiber insulating material may he a weaved (or serimped) material as well as a felt type material. The synthetic fiber insulating material usually also comprises a finish which can be tailored to specific applications as would be well appreciated by a skilled artisan.
[0021] The inventors have found that if the synthetic fiber insulation material is used as a second layer to lag the portions of the container having high thermal conductivity, this reduces heat transfer to the chamber and provides a substantial increase in effectiveness. Typically, this enables the internal temperature of the container to remain at 100°C or less whilst exposed to an external temperature of 300°C for a duration of two hours. Alternatively, the synthetic fiber material may be used to lag at least a portion of the contents positioned within the chamber of the container.
[0022] The intumescent material used in the invention is typically an intumescent foam and it is often the case that the intumescent material comprises intumescent graphite. Such materials are useful in the fire proof container as they expand when exposed to heat. Typically. these materials are positioned about regions of the containers were gaps or ports are present to seal any air gaps in the event of a fire.
[0023] The third layer of the container is typically made from a rigid material. The inventors have found that existing containers can he outfitted with layers of material as described herein to repurpose existing containers for use as fire proof containers.
The third layer may therefore serve as a scaffolding about which the various layers described herein can be positioned. As such, it is advantageous to use rigid materials.
[0024] Often, the third layer will be manufactured from a fire resistant plastics material and the third layer may be made from glass reinforced plastic (GRP).
[0025] Typically, the walls of the fireproof container have a thickness in the range of 10mm to 50mm and maybe in the range of 20mm to 40mm. It is often the case that the walls have a thickness in the range of 10mm to 50mm.
[0026] It is sometimes the case that the fireproof container further comprises a fourth outermost layer. The term "outermost" is intended to mean that the fourth layer is the layer on the outside ol the container which is exposed to the elements or fire (in the event of a fire). It is typically the case that the fourth layer is directly adjacent the first layer, however it is possible that there may he one or more layers between the first and fourth layers. For example layers of adhesives or additional insulating or intumescent material may he sandwiched between these layers in order to alter the thermal properties of the container.
[0027] This fourth layer cm be used to provide structure to the container and/or can including indications and markings. Examples of such indications or markings may include instructions for operation of the control box and/or the container, warnings notices or fire safety information.
[0028] The fourth layer may be a fire resistant coating which is applied to the first layer of the container. This may include fire retardant chemicals andlor agents which modify the physical and thermal properties of the insulating foam material. It is typically the case that the fourth layer is a coating material selected from Fabshield LP12O5 (RTM). This is advantageous as the containers undergo wear and tear throughout the course of their lifetime. Muhiple openings, closings and remountings can damage the outer skin of the container. It is therefore important that outer first layer of synthetic fiber insulating material does not become significantly damaged in normal use as otherwise it wifl not perform correctly iii the event of a lire.
[0029] Alternatively, the fourth layer may a casing. The casing may be fabricated from a variety of materials that show good fire resistant. However, typically, the easing is made from fire resistant plastic which may be glass reinforced plastic.
[0030] The skilled person would understand that the container could also include both types of fourth layer descnbed above. As such, the container may include a coating layer may be applied to the insulating material and this in tern may be located within a casing as described herein.
[0031] Control boxes and other electric devices typically include cables which communicate with a range of devices within a building. Therefore, the container may he equipped with one or more ports for receiving cables. Often, these ports will comprise a seal in order to prevent flames, hot air or smoke from entering the container via the ports. Tf a port seal is breached, the ability of the container to keep the contents at less than 100°C is reduced. The seal may be made from an elastic material, typically a rubberised or neoprene material which closes around the penmeter of cables and forms a tight seal together with the container. Alternatively or in addition to this, the ports may extend through the wall of the container and through the at least one region of intumescent material. Accordingly. when the intumescent material becomes hot, it will expand and seal any gaps permitting air, flames or smoke into the container.
[0032] The fireproof container may comprise a base portion and one or more walls extending upwards relative to the base. The container is, in one example, intended to he fitted with wall mounted control units and other wall mounted electronic or mechanical devices. Therefore, a base portion is often provided to which control units and the like can be secured to. These ensures that when positioned on a wall, an air gap is maintained between the inner surface of the container and the control unit or the like. The base portion may also bc used as a platform for fastening the containcr, with or with a contents, to wall or other suitace. The base may be fabricated from a different material to the walls. This face is typically adapted to abut against the wall on which the control unit sits. Accordingly, the external face of the base is not exposed to fire when positioned on a wall. It may he that the base is manufactured from wood which may be treated with one or more fire resistant chemicals.
[0033] It is typically the case that the container further comprises a lid portion which is cngageahlc with the one or more walls of the container to form a sealed chamber.
Although structures without lids are envisaged, it is useful to have a lid portion which can be removed and attached to the walls of the container in order to create an enclosed space or chamber and which also allows easy access to said space. This enables the lid to he removed when maintenance or operation of the electrical andlor mechanical device housed within the container is required and replaced once work is complete. Often, the lid portion is an integral part of the container and typically, the lid portion is hinged. In addition, when in use, the lid forms may form one of the walls of container.
[0034] In one embodiment, the lid comprises a fabric hood attached to the underside of the lid which, when the lid is positioned on the container, abuts against the contents or the container. Where the contents of the container is a control box, the fabric hood may contact a surface of the control box in order to from an effective seal between the lid and the container. The fabric hood is typically made from a synthetic fiber insulating material as described herein.
[0035] There is no particular restriction on the shape ol the container, hut it is typically the case that the container is substantially cuboid or box-shaped. This shape co-operates with most control units and other electrical or mechanical systems and is also straight forward to manufacture and retrofit to existing containers.
[0036] The contents of the container may comprise a control box and it is usually the case that the control box is encased in a casing material having a melting point of greater than 95°C. The container is therefore generally adapted to maintain a temperature of 100°C or less. This is because, if the temperature is high enough to melt the casing of the control box to he protected, then molten materia' (usually a plastics material) can seep into the control box and disrupt the electronic and mechanical systems continued within. Further, many electronics are themselves sensitive to heat and can melt or become damaged even if a heat resistant plastic is employed that resists becoming molien at high temperatures. However, in view of the risks associated with using lower melting point casing materials, such as plastics materials, typically it is the case that the casing material is a metal or metal alloy. For example, the casing material may comprise aluminium.
[0037] As mentioned above, the container is often adapted to maintain an internal temperature of 100°C or less when the container is exposed to a fire of 300°C for at least two hours. Further, it is typically the case that the container is adapted to maintain an internal temperature of 100°C or less when the container is exposed to a fire of 400°C for at least thirty minutes.
[0038] In a second aspect of the invention, there is provided a use of a fireproof container according to the first aspect of the invention, for protecting a contents of the container from a lire. Typically, the contents is an electronic or mechanical device.
[0039] In another aspect of the invention, the fireproof container cm be made by attaching fireproof "walls" to the faces of existing boxes. Panels or sheets of material having the layered structure outlined above can he attached to the external laces of a container in order to clad the existing container in a fireproof skin. This allows existing systems to be retrofitting to provide thermal protection. Unless otherwise stated each of the integers described may be used in combination with any other integer as would be understood by the person skilled in the art. Further, although all aspects of the invention preferably "comprise" the features described in relation to that aspect, it is specifically envisaged that they may "consist" or "consist essentially" of those features outlined in the claims. In addition, all terms, unless specifically defined herein, are intended to be given their commonly understood meaning in the art.
[0040] Further, in the discussion of the invention, unless stated to the contrary, the disclosure of alternative values for the upper or lower limit, of the permitted range of a parameter. is to be construed as an implied statement that each intermediate value of said parameter, tying between the smaller and greater of the alternatives, is itself also disclosed as a possible value for the parameter.
[0041] In addition, unless otherwise stated, all numerical values appearing in this application arc to he understood as being modified by the term "about".
