  • a disadvantage of the known solution is that the heat-insulating material in it has an increased weight and low flexibility, which complicates its use and application, for example, when connecting individual elements of the product into a single unit, as well as its low efficiency due to insufficient reduction of the thermal conductivity of the layers of its insulation.
  • a more effective flexible thermal insulation material is known (RF Patent for the invention N ° 2194915) containing a base in the form of a layer, a metal layer and an adhesive, characterized in that a heat-resistant polymer layer with a softening temperature of at least 1 10 ° C and a melting point of below 140 ° C, fixed by adhesive on the base, the metal layer is made in the form of an opaque metallized coating of the polymer layer deposited on the latter from the opposite side of the side, and the base is in the form of a woven or non-woven layer th material.
  • the known invention also has insufficiently low total thermal conductivity, which reduces its effectiveness, and also has low adaptability, due to the complexity of its installation on pipelines and (or) thermal equipment with high operating temperature.
  • the purpose of the claimed utility model is to overcome the shortcomings of known heat-insulating systems by achieving a technical result - increasing the efficiency and manufacturability of a flexible heat-insulating material, in particular a roll type.
  • a multilayer flexible heat-insulating material containing at least three layers of insulation from non-woven material, and at least two of them are bonded with aluminum foil by adhesive.
  • the first layer of insulation is a foiled needle-punched mat made of fiberglass with a thickness of 6 to 12 mm and a foil thickness of 35-50 microns.
  • the second (next) layer of insulation is ceramic fiber with a thickness of 9 to 75 mm.
  • the foil needle-punched mat made of fiberglass with a thickness of b to 25 mm and a foil thickness of 40-55 ⁇ m was used as the final surface layer of the insulation, and quick-hardening adhesive was used as an adhesive.

  • the inner insulation layer formed from ceramic fiber of low thermal conductivity very well prevents heat consumption from heated pipe into the surrounding space by direct heat transfer and partially convection. At a sufficiently high temperature of the operated pipeline, the amount of heat loss will increase due to increased thermal radiation. To combat heat loss from infrared radiation, the inner layer of the foil is intended to be glued to the surface of the first insulation layer in the form of a fiberglass needle-punched mat.
  • the use of fiberglass insulation as the first layer precisely in the interval from 6 to 12 mm is due to the need to achieve the following technical result: such a thickness is less than 6 mm the material does not provide sufficient thermal insulation properties, and with a thickness above 12 mm, manufacturability is unreasonably reduced when the insulation layer is wound, since the flexibility of the material is reduced, which leads to a significant increase in the complexity and complexity of this operation.
  • the thickness of the foil coating from 35 to 50 mm thick is determined by the fact that a thinner foil when working with it in this operation often breaks and periodically needs to be replaced, and a thicker foil does not provide sufficient flexibility for the metallized layer of insulation, increasing labor intensity and thus , reducing the manufacturability of the operation of its winding.
  • a thickness of less than 9 mm of such material does not provide the required thermal insulation properties, and with a thickness of more than 75 mm, manufacturability is unreasonably reduced when winding the inner layer of the insulation, since the flexibility of the material is significantly reduced, which inevitably increases the complexity and, as a consequence, the complexity of this operation; however, this material is more flexible in its properties than a fiberglass mat, which makes it possible to use a thicker layer (up to 75 mm).
  • a fiberglass insulation layer as a finishing (external, surface) layer precisely in the range from 6 to 25 mm is due to the need to achieve the following technical result: the thickness of a fiberglass mat less than 6 mm does not provide sufficient thermal insulation properties, and unnecessarily decreases with a thickness above 25 mm manufacturability when winding a layer of insulation, as the flexibility of the material decreases, which leads to a significant increase in the complexity and complexity of this operation, but unlike the operation winding the first layer, the diameter of the finishing layer is somewhat higher, which causes the possibility of increasing the thickness of the material used up to 25 mm without substantially reducing the complexity, and hence the processability.
  • the optimal thickness of the foil layer is also determined. So, not allowing the possibility of breaking through the foil with a thickness below 40 mm, it is permissible to use its thickness up to 55 mm without significantly increasing the stiffness of the material, which ensures a sufficiently high level of manufacturability in this operation.
  • the design of the inventive multilayer flexible heat-insulating material ultimately leads to a decrease in the total heat loss of an operated pipeline or other thermal equipment.
  • the use in the inventive utility model of quick-hardening glue and fixing each layer of insulation with a tape retainer makes it easy to assemble, which improves processability.
  • Foil mats are manufactured industrially by caching standard needle-punched fiberglass mats with foil, the use of tape retainer for assembling the inventive multilayer flexible heat-insulating material ensures the simplicity of this process, which does not require highly skilled workers.
  • the high adaptability of the inventive multilayer flexible thermal insulation material ensures its widespread use in industry, in particular in the field of heat power.

Abstract

Le matériau d'isolation thermique souple à couches multiples comprend au minimum trois couches d'isolant en non-tissé dont au moins deux sont recouverts au moyen d'un adhésif par un feuil d'aluminium. La première couche de matériau isolant est constituée par une natte aiguilletée recouverte de feuil, en fibre de verre d'une épaisseur de 6 à 12 mm, et d'un feuil d'une épaisseur de 35-50 micromètres. La deuxième couche (couche suivante) de matériau isolant est constituée d'une fibre d'une épaisseur de 9 à 75 mm. On utilise en tant que couche de finition de surface la natte aiguilletée recouverte de feuil, faite en fibre de verre d'une épaisseur de 6 à 25 mm, et d'un feuil d'une épaisseur de 40-55 micromètres. On utilise en tant que adhésif une colle à durcissement rapide. Pour améliorer le confort de formation, chaque couche d'isolant est fixée par une fixation à bande.
