Definitions
- Intumescent materials have been known for many years and have been developed to the point where some claim to provide thermal protection up to approximately 2000°F. However, this is not a sufficiently high level of fire protection in a number of environments, including home, office, and industrial applications.
- intumescent materials are not capable of conducting an electric current and becoming part of an electrical circuit. Thus, they are not presently capable of forming part of an alarm system, or being used as an antenna, or preventing electromagnetic interference (EMI), or radio frequency interference (RFI). Accordingly, it is an object of the present inventio to provide an improved fire-retardant an electrically-conductive coating material that is effectiv at continuously-maintained temperatures as high as 4000° and that can be used in a number of different application to protect various types of substrates.
- EMI electromagnetic interference
- RFID radio frequency interference
- fire-retardant and electrically-conductive coating materia which includes a fluid intumescent material and a electrically-conductive material of various sizes disperse or suspended therein for particular applications.
- Th fluid intumescent material includes a foaming agent, blowing agent gas source, a carbonific or charring agent, film-forming binder, a solvent and, in some cases, pigment or filler.
- the electrically-conductive materia consists of a particle substrate and a conductive coating. In certain applications, such as housing and building frames to be coated, electrically-conductive particles having a bulk length of at least 1/32" are employed.
- larger electrically-conductive particles are employed having a bulk length of 1" to 4" or greater to provide a thicker coating consistency, which, in some cases, can be applied by using a trowel.
- the larger size particles also increase the amount of conductivity.
- milled particles are employed to provide a coating having a consistency which can be applied by painting or spraying and provides a fine or smooth finish, whereas the larger size particles provide a somewhat coarser finish or coating. In this manner, different size particles are employed, depending on the substrate to be protected by the fire-retardant, fire suppressant, and electrically-conductive coating material of the present invention.
- Figure 3 is a diagrammatic illustration of what happens to the coating material after prolonged application of heat
- Figure 6 is a diagrammatic illustration of the substrate of the conductive material being in the form of fibers
- the fluid intumescent base material consists of the following:
- Foaming agent such as mono- 10% to 40% ammonium phosphate, diammonium phosphate, ammonium polyphosphate, or potassium tripolyphosphate, or combinations thereof (in powder form or granules)
- composition of the present invention has a number of different applications and uses.
- the composition of the present invention is best suited for spraying onto residential structures and any other suitable surfaces.
- the composition of the present invention is best suited for industrial and commercial applications, such as structural beams and columns, floors, ceilings, elevator shafts, pipes, electrical cables, ducts, fire doors, stair wells, passageways, boiler rooms, electrical closets, electrical panel boards, and the like.
- the article to be coated can be dipped into the conductive coating and allowed to harden before it is used.
- the combination of conductive material and intumescent base material can be used as an effective fire-retardant material at continuously-maintained temperatures up to as high as
- a gallon of the intumescent material of the invention was mixed with 30 ounces of milled conductive fibers using an air jet.
- the composition was applied to an aluminum sample and tested in the same manner as described in Example I, and the same results were achieved as described in Example I.
- a gallon of the intumescent material of the invention was mixed with 30 ounces of long conductive fibers (1" to 4" bulk length) using an air jet.
- the composition was applied to an aluminum sample and tested in the same manner as described in Example I, and the same results were achieved as described in Example I.
- a gallon of the intumescent material of the invention was mixed .with 15 ounces of short conductive fibers (1/4" to 1/2" bulk length) and 15 ounces of long conductive fibers (1" to 4" bulk length) using an air jet.
- the composition was applied to an aluminum sample and tested in the same manner as described in Example I, and the same results were achieved as described in Example I.
- a gallon of the intumescent material of the invention was mixed with 15 ounces of milled conductive fibers and 15 ounces of long conductive fibers d" to 4" bulk length) using an air jet.
- the composition was applied to an aluminum sample and tested in the same manner as described in Example I, and the same results were achieved as described in Example I.
- Figure 1 illustrates how the composition 10 of the present invention operates when applied to a substrate 12, such as wood, aluminum, steel, a fabric, or any other usage mentioned herein.
- Composition 10 includes conductive particles, in the form of fibers 14, in bulk, as described herein in accordance with the present invention, dispersed within or mixed within the intumescent base material 16, as described herein in accordance with the present invention.
- Figure 2 illustrates what happens when heat initially reacts with the outer layer 16a of intumescent material and before the heat reaches the inner layer 16b of intumescent material. During this initial stage of heat application, the inner layer 16b is unaffected, but the outer layer 16a swells and expands as a result of air bubbles 16c being formed. These air bubbles 16c build up an outer barrier to protect the substrate 12.
- Figure 3 illustrates what happens when the heat builds up and reaches the inner layer 16b.
- the inner layer 16b starts to swell and expand as a result of air bubbles 16d being formed within the inner layer 16b. These air bubbles 16d build up an inner barrier to protect the substrate 12.
- the air bubbles 16c and 16d increase in number and in size until the air bubbles engage the conductive fibers 14.
- the fibers 14 then interfere with the air bubbles 16c and 16d continuing to increase in size and thus operate to limit or control their size.
- more and smaller air bubbles or air cells are formed, as compared to intumescent materials in the prior art, which typically have no restraints on the increasing size of the air cells being formed.
- Figure 4 diagrammatically illustrates the conductive material 14 in detail, including the inner substrate 14a, the conductive coating 14b, and surrounded by the intumescent material 16.
- Figure 5 diagrammatically illustrates the substrate 20 of the conductive material being in the form of spheres which overlap to form a conductive network.
- Figure 6 diagrammatically illustrates the substrate 22 of the conductive material being in the form of fibers which overlap to form a conductive network.
- Figure 7 diagrammatically illustrates the substrate 24 of the conductive material being in the form of flakes which overlap to form a conductive network.
- Figure 8 diagrammatically illustrates the substrate 26 of the conductive material being in the form of granules which overlap to form a conductive network.
- the conductive coating of the present invention can be used to conduct current, it can be used to apply heat to surfaces onto which it is coated.
- the conductive coating can be applied to aircraft fuselages, and when current is applied to the coating, it will heat up and melt ice on the fuselage.
- the coating composition of the present invention can be applied to any substrate, and when heat is applied at any temperature in the range of 350°F and 4000°F and higher, the coating will expand approximately 2 to 12 times or greater than the original thickness of the coating that is applied and thus provide a superior thermal barrier relative to the substrate being protected, as well as a coating which is electrically conductive, for carrying current, applying heat, or for RFI and EMI shielding.
