Definitions
- the present invention relates to a novel intumescent composition.
- the composition relates to an intumescent composition having improved properties.
- the intumescent material of the present invention finds particular utility in construction.
- Intumescent materials are substances that swell upon exposure to heat and produce a char. Because the materials swell and char they are poor conductors of heat and are used in passive fire protection. However existing intumescent compositions have a number of drawbacks, which can limit their use in certain applications.
- the intumescent compositions of the present invention are useful to provide fire retardant barriers in many construction applications, for example in ventilation units, to provide fire resistant sealants around doors and windows, and for use in ducting, air transfer grills and cable transit tubes.
- Some intumescent compositions of the prior art are not suitable for a range of applications. For example some intumescent materials need to reach very high temperatures before swelling and thus do not protect against fires which are small or at some distance away. These fires may still produce high levels of smoke which may be toxic and can cause significant damage to property. Some intumescent materials only swell by a small volume and thus cannot be used to close large spaces. Some intumescent materials swell only very slowly and thus significant smoke damage can occur before a complete seal is formed. Some materials do not form a very dense char and thus the intumescent material can be blown away causing the barrier to break down. It is also desirable that a fire stop barrier is not too bulky in normal use and does not affect normal operation of the opening which it is intended to seal in the event of a fire.

- the mesh is suitably substantially adjacent to the fin or fins.
- the damper comprises two meshes and the fin or fins are positioned therebetween.
- the mesh is suitably provided to prevent expanded intumescent material from being blown away through the ducting.
- the damper of the present invention comprises a ring shaped housing comprising a plurality of fins which comprise an intumescent composition ; wherein each circular face of the housing is closed by a mesh and wherein the fins are substantially parallel to each other and substantially perpendicular to the meshes.
- the or each fin of the dampers of the present invention comprises an intumescent composition.
- each fin is coated with the intumescent composition.
- each side of each fin is coated with the intumescent composition.
- Figure 1 shows a damper of the present invention
- Figure 2 shows a cross-sectional view of the damper of figure 2.
- Figure 3 shows the damper connected to a portion of ducting. Preferred features of this embodiment will now be described. However it will be appreciated that these features may as appropriate apply to other embodiments of the invention.
- the damper comprises a ring shaped housing 1 which is made of steel. Within the housing are a plurality of parallel fins 2 which are affixed to the internal surface of the housing 3. The fins each comprise a number of apertures 4. However it will be appreciated that fins which are solid or which are in the form of a grid or mesh could also be used.
- the fins in a preferred embodiment are made of steel but alternative materials may be used. In the embodiment shown the fins are spot-welded onto the inside of the housing, but other methods of fixing the fins into the housing are within the scope of the invention.
- Each fin is coated on both sides with a layer of intumescent material 5. This is only shown on the bottom fin in figure 2. However embodiments in which only one face of the fin is coated are also within the scope of the invention.
