  • a typical specific heat for such a material is around SkJ.g ' 1 .
  • a constraint to using more alumina trihydrate (and thereby a greater endothermic effect) is that the specific heat of the alumina (that results on dehydration of the alumina trihydrate) is relatively high such that heat retained at the surface of the insulation after exposure to temperature can percolate through the insulation.

"Free water” (water in physical contact with the material which is free to flow away or evaporate) is not excluded from being present but is not necessary.
  • the endothermic materials may comprise endothermic materials set with an additional material providing a hydraulic bond, or the endothermic materials may themselves provide a hydraulic bond.
  • Suitable materials for use in the insulating material and capable of forming a hydraulic bond include (without limitation) hydratable alumina, high alumina cement, Portland cement, and plaster.
  • the materials may comprise alumina trihydrate bonded with hydrated hydratable alumina: or hydrated hydratable alumina may provide both the hydraulic bond and the endothermic material.
  • Hydratable aluminas are finely divided microporous alumina particles that readily hydrate and bond with each other or other particles to form a hydraulic bond. They are sometimes known as transition aluminas or activated aluminas and are formed by thermal decomposition of aluminum hydroxides or oxyhydroxides. Suitable materials include Alphabond ® from Alcoa, or Dynabond 3 activated alumina binder, from AluChem, Incorporated.

  • the materials may be made by forming a wet mixture, forming the resultant mixture into shape by casting or pressing, and permitting the mixture to undergo a hydraulic reaction, causing the mixture to set. If necessary the resultant material may be machined and tooled.
  • the hardened material is dried to a sufficient extent to remove free water, but not to remove chemically bound water. Other forming methods are not precluded (for example, spraying, troweling, or rolling).
  • a typical process for producing a thermal insulation material according to the present invention may follow the following steps:
  • the solid components are dry mixed [for instance, but not necessarily, in a Hobart mixer]. Once a suitably homogeneous mix is attained, continue the mixing process and add the water.
  • the flow and set time of the wet mix can be altered through the use of flow and set time additives.
  • the shaped material may be produced via pressing instead of casting; if so additives may be added to improve pressing behaviour. It has been discovered that if pressing substantially lower pressures are required compared to pressing of prior art microporous based- materials. Comparative Example 1
  • thermal insulation materials For the purpose of testing the properties of thermal insulation materials according to the invention, the materials were compared to an existing prior art material currently supplied to the industry for the purpose of flight data recorder protection. This formulation is as set out in Table 1 above.
  • the test standard for thermal insulation materials for the protection of flight data recorders is EU Civil aviation test procedure ED-212.
  • the US Federal Aviation Authority requires that solid state recorders must survive a minimum of 60 minutes under testing conditions.
  • the test entails setting up a flight data recorder can housing the thermal insulation, and directing three propane burners at the can to maintain a temperature at the surface of the can within the range of 933°C-1100°C (1712°F to 2012°F), with 1093°C (2000°F) being the target.
  • the temperature at the core of the thermal insulation material ["inside can temperature"] must not reach or exceed 260°C (500°F).
  • Figure 1 shows the thermal profiles measured in a test comparing the performance of the prior art material of Table 1 and a sample of 100% alumina trihydrate (ATH) formed by hydration of hydratable alumina with water using the method outlined above.
  • ATH alumina trihydrate
  • the temperature inside the can continues to rise as heat stored in the outer part of the can percolates inwards as the outer part cools.
  • the maximum temperature approaches the 260°C (500°F) at around 90 minutes whereas for the 100% ATH material the maximum temperature is significantly below the 260°C (500°F) at around 90 minutes.
  • Fig. 2 shows the result of using vermiculite as a filler in varying amounts in materials formed by the method outlined above and comprising alumina trihydrate (ATH) formed by hydration of hydratable alumina with water using the method outlined above.
  • ATH alumina trihydrate
  • the material behaves worse than the standard material: whereas with only 5% it is similar to the 100% ATH product of Example 1; again shows the maximum temperature significantly below the 260°C (500°F) level at around 90 minutes; and shows that the core is kept below 149°C (300°F) for the entirety of the 60 minutes.
  • the material with 25% vermiculite loading evolved about 240 kg.m “3 [15pcf]; that with 15% vermiculite loading evolved about 336 kg.m “3 [21pcf]; and that with 5% vermiculite about 528 kg.m “3 [33pcf].
  • fillers in this case vermiculite
  • materials of lower heat capacity per unit volume than the at least partially dehydrated residue of the endothermic material in this case alumina, following degradation of alumina trihydrate
  • the filler is substituting for endothermic materials, provision of too much filler reduces the effect of the endothermic.
  • Figure 3 shows the thermal profiles measured in a test comparing the performance of the prior art material and samples of thermal insulation materials produced according to the method outlined above. Each time, hydratable alumina, vermiculite, and water were used in the production of the thermal insulation material in such proportions that, after drying, the thermal insulation material comprised 95% of alumina trihydrate and 5% vermiculite (all percentages by weight). The samples of thermal insulation material varied in the temperature at which the materials were dried.
  • thermal insulation material produced according to the method of the present invention provided a superior performance to the prior art material: but also increasingly superior thermal insulation is produced as the drying temperature decreases, with the best results arising when the thermal insulation is dried at room temperature (said sample not quite reaching a core temperature of 149°C (300°F)).
  • drying takes place below 50°C, below 40°C or preferably at 30°C or below.
  • Example 4 Figure 4 shows the thermal profile measured in a test comparing the performance of the prior art material (plain line) and a sample of thermal insulation material prepared as in Example 3 and air dried (line with marker ⁇ ). However in this test the burners operated for 90 minutes instead of the
  • phase change materials in addition to endothermic materials comprising chemically bound water, permits absorption of heat through phase change.
  • Phase change materials typically are materials having a high heat of fusion, absorbing heat in the process of melting.
  • waxes provide a particularly useful material in this respect, since they may start to absorb heat through melting at relatively low temperatures, and can further absorb heat through vaporization at higher temperatures. The vapors produced can dissipate and take heat away from an article being protected.
  • Fig 6 shows temperature profiles for materials produced by setting a slurry comprising hydratable alumina and phase change material beads in the proportions for casting Mix A and casting Mix B set out in Table 3 below.
  • phase change material used (Microtek Laboratories MPCM 43D - microencapsulated phase change material), comprised a paraffin wax core material encapsulated in a polymer shell, having mean particle size 17-20 ⁇ and with a melting point in the region of 43°C.
  • Fig 7 shows temperature profiles at several points inside a module insulated using insulation formed by casting from the components of Table 5:
  • sodium carbonate evolves carbon dioxide endothermically at the elevated temperatures experienced in a fire, and the carbon dioxide produced can carry heat away, so both endothermic cooling and gas transfer will contribute to removing heat from the insulation material. This shows the advantage of having endothermic materials that liberate gases other than water vapor.
  • phase change materials having a phase change at temperatures between 25 Q C and 260°C provides additional absorption of heat in the core of the insulation, so lessening the amount of evolved water that needs to be evolved to maintain a given temperature. More than one phase change material may be used to provide cooling over a range of temperatures.
  • a pressing formula would ideally have significantly less water than a cast mix. Casting uses more water than is necessary to produce a hydraulic bond and this excess water can impair mechanical properties and require excessive drying times. By using water at a level such that the process of hydraulic bonding takes up all or most of the water during the setting process, detrimental effects of excessive water can be reduced.
  • Table 5 the formulation shown in Table 5, with the amount of water reduced to 25 parts by weight can be pressed
  • Fig. 8 shows in like manner to Fig. 7, temperature profiles at several points inside a module insulated using insulation formed by pressing the modified formulation.
  • the mixture is fluent enough that it can be pressed around an article to be insulated, providing that article has strength enough to resist the pressures involved.
  • Component Amount (parts by weight)
  • thermal insulation materials according to the present invention can pass substantially more stringent testing conditions than currently apply, conditions which would otherwise cause prior art thermal insulation materials to fail catastrophically.
  • the improved thermal protection provided by the materials of the present invention will permit less insulation material (by volume) to be used than previously, while still meeting the current regulatory tests. This will permit manufacture of data recorders occupying less space [and mass] than is currently required; or to allow for a greater volume of recording apparatus while retaining the same outside dimensions.
  • the hydraulic binder [which may be or form part of the endothermic material and is preferably hydratable alumina]) undergoes a hydraulic reaction - (so hydratable alumina will form alumina hydrates, including alumina trihydrate).
  • This hydraulic reaction hardens the shape after forming, allowing it to be machined and painted as required.
  • thermal insulation materials produced according to the present invention undergo less heating at the core after external heat sources are deactivated than the prior art materials.
  • One factor contributing to this is the use of filler material having a lower volume heat capacity than the at least partially dehydrated residue of the endothermic materials, minimizing the extent of core heating after the heat source is removed by minimizing thermal mass.
  • Such materials e.g. vermiculite, perlite
  • vermiculite perlite
  • Such materials also reduce the mass of the as-made product, weight being an important factor in aerospace applications.
  • Tested formulations show a 50% improvement in thermal insulation behavior over the prior art material with only a 20% increase in mass and this weight difference may be further minimized, for instance by optimizing the formulation density to balance thermal mass, thermal conductivity/insulation and endothermic ability.
  • compositions comprising the following components of Table 8 were cast and dried:- Table 8
  • Formulations according to the present invention also do not require (but do not preclude) opacifiers or the use of insulation fibers for product performance, unlike prior art materials.
  • Endothermic fillers may be added to work in conjunction with the hydrated hydraulic binder to increase endothermic potential and the timing/temperature at which the heat absorption occurs during a thermal event.
  • Air-setting binders may be added to add strength after drying, in order to prevent cracking and improve machinability. Their inclusion may reduce the amount of hydraulic binder needed if so desired.
  • Including a glass former into the formulation helps reduce open porosity, thereby slowing the convective transfer of hot air from the surface to the core of the thermal insulation material.
  • Such glass formers may either come from water glass air setting binders (silicates) or through

  • thermal insulation material may be shaped by casting or pressing under light load, it is even possible to incorporate the flight data recorder electronic data collection module into the lining as a monolithic piece, eliminating the need for an access port to allow for placement into the center of the module after forming and machining.
  • Other forming methods can be used to apply the materials, for example by spraying, troweling, or rolling.
  • An important advantage of the present materials is that they do not require exposure to high temperature during manufacture so enabling the retention of high quantities of endothermic materials that might otherwise degrade (for example at temperatures as might occur in curing a resin binder).
