Definitions

  • crude thermal insulation materials are composed of up to several inches of non-woven fiberglass fabric to ensure convective and conductive thermal insulation.
  • thermal insulation material 1 aims to insulate for instance, warmer parts of industrial installations.
  • This thermal insulation material 1 is divided into two parts which are high and low surface layers 2, 3 and a body 4 respectively, wherein both surface layers 2, 3 are aluminum foils; and the body 4 part consists of fiberglass fabric 5 and a glue solution 6.
  • the fiberglass fabric 5 is bonded to the aluminum foils by the glue solution 6 prepared from an epoxy resin previously treated by a fire retardant and a curing agent.
  • the insulation material used in CN101920587 may fuel the fire by creating flammable gases or fire-lit droplets, or may create toxic smoke.
  • the aim of the invention is therefore to overcome the drawbacks and meet the expectations listed above.
  • the invention therefore relates to a thermal insulation material, comprising inner and outer layers of reflective material with a reflectivity over than 90%, a non-combustible material located between said inner and outer layers and bonded to said inner and outer layers by a polymeric primary bonding agent containing a load of fire-retardant, characterized in that said polymeric primary bonding agent contains a load of fire-retardant.
  • the idea of the invention is therefore to provide a chemically inert radiative heat shield with overall mechanical strength and a fire retardant capacity.
  • the non-combustible material is chosen in the group comprising light weight mesh and fabric made material;
  • each additional layer comprises vent holes
  • each additional layer has a thickness of about 10 ⁇ ;
  • the outer layer is coated with an external layer made of a material that become less reflective when exposed to excessive heat to increase radiative losses toward the outside and dissipate excessive heat;
  • the inner and outer layers are made of aluminum foil; aluminum material advantageously provides radiative heat shielding;
  • the inner and outer layers have a thickness of about 30 ⁇ ;
  • the lightweight mesh or the fabric made of non-combustible material is fiberglass-based; advantageously provides mechanical strength, while being chemically inert, especially non-combustible;
  • the polymeric primary bonding agent contains primarily Polyethylene; the polymeric primary bonding agent contains Ethyl Vinyl Acetate; Ethyl
  • Vinyl Acetate (EVA) is advantageously used to increase the adhesion and bonding strength
  • the polymeric primary bonding agent contains Ethylene Methyl Acrylate; Ethylene ethyl Acrylate (EMA) is also advantageously used to increase the adhesion and bonding strength;
  • the inner layer is bonded to a layer of conductively-convectively insulating material, such as fiberglass or other mineral fiber-based « wool » or other specially fire-safe material.
  • FIG. 1 illustrates a thermal insulation material of the prior art
  • figure 2 illustrates a thermal insulation material according to an embodiment of the present invention
  • figure 3 illustrates a thermal insulation material according to another embodiment of the present invention
  • the thermal insulation material 10 comprises inner and outer layers 1 1 , 12 of reflective material. Different kinds of reflective materials can be used with a reflectivity over than 90%.
  • the aluminum is chosen because of its high reflectivity, and because of its adapted emissivity which can be improved after a polishing step.
  • both layers have a thickness from about 30 ⁇ . However, it is possible to vary the thickness of both layers 1 1 , 12 independently one another.
  • the inner layer 1 1 is in contact with a thick primary conductive- convective insulation layer 13, whereas the outer layer 12 is in contact with outside heat sources, indicated by reference HS.
  • the inner layer 1 1 further comprises several through vent holes 14, in the width over its entire surface.
  • Both layers 1 1 12 and non-combustible material 15 are bonded together by a polymeric primary bonding agent 16 containing a load of fire-retardant material.
  • the polymeric primary bonding agent 16 comprises primarily polyethylene, but can be also chosen among the non limitative list comprising Ethyl vinyl acetate (EVA) and Ethylene methyl acrylate (EMA).
  • the thermal insulation material 10 comprises first and second additional layers 17, 18 of reflective material located between the inner layer 1 1 and the non-combustible material 15, and bound to the inner layer 1 1 and the non-combustible material 15 by the polymeric primary bonding agent 16.
  • Different kinds of reflective materials can be used as the same manner as for the inner and outer layers 1 1 , 12.
  • the first additional layer 17 is bound to the non-combustible material 1 5 whereas the second additional layer 18 is bound to the first additional layer 17 and to the inner layer 1 1 .
