Definitions

  • the present invention relates to an insulation material that provides sound and heat insulation.
  • bitumen is added into a solvent and is dissolved by being subjected to heat.
  • the fiber composite comprising fly ash is heated and the prepared bitumen solution is applied on the composite by spraying. Afterwards, the material to which hot-press is applied is dried and cooled, and thus the bitumen modified fly ash fiber composite is produced.
  • adding bitumen increases the impact strength, compressive strength and tensile strength of the material.
  • the used fly ash is the waste product of another process, the size of the particles is not controllable and their surfaces do not allow application of coating.
  • a thermal insulation material is formed between the bitumen material and the washing tub in order to improve the insulative properties of bitumen.
  • the said thermal insulation material is composed of foam glass granulate or clay foam material.
  • the aim of the present invention is the realization of an insulation material that provides effective sound and heat insulation.
  • the insulation material realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, is manufactured by mixing bitumen with hollow and equally sized ceramic microspheres.
  • the vibration dampening and heat insulative properties of the bitumen material are improved, and the heat moving away from the washing tub and the noise and the vibration transferred to the outside surrounding are minimized.
  • the microspheres being of ceramic material and the sphere shape facilitates adding thereof into bitumen.
  • the spheres being microsphere shaped provide their radiation reflecting properties to be at the desired level.
  • the microspheres are mixed into bitumen after being coated with a metal oxide such as T1O2, SnO2, CeO2, etc., suitable for reflecting the rays in the desired radiation wavelength. Accordingly, the ray reflecting property of the microspheres and hence the thermal insulation capability of the insulation material are increased.
  • the microspheres are mixed into bitumen after being coated by a compatibilizer material such as a polymer containing siloxane, an amine group, etc.
  • microspheres mixed into bitumen are in the ratio of 20 to 50,
  • microspheres preferably 30 percent by weight.
  • the dimensions of the microspheres are in between 50 to 300 micrometers.
  • the dishwasher comprises an insulation material that at least partially surrounds the outer surface of the washing tub.
  • the cover comprises a plate that faces the inside and an outer cover that faces the outside of the washing tub.
  • the plate is produced from metal material.
  • the outer cover is secured onto the plate and forms the portion of the cover that the user can view from the outside.
  • the insulation material is
  • Figure 1 - is the schematic view of the insulation material.
  • Figure 2 - is the schematic view of a dishwasher wherein the insulation material is used.
  • the insulation material (1) is formed by mixing bitumen (2) with hollow and equally dimensioned ceramic microspheres (3). Accordingly, an insulation material (1 ) is obtained that provides high sound and heat insulation that is low in cost and easy to manufacture.
  • the material (1 ) is composed by mixing the microspheres (3) coated by a metal oxide suitable for reflecting the rays in the desired radiation wavelength into bitumen (2).
  • a metal oxide such as T1O2 , SnO 2 , CeO 2 , etc.
  • the insulation material (1 ) is composed by mixing the microspheres (3) coated by the compatibilizer material into bitumen (2). Accordingly, the insulation material (1 ) is provided to be easily adhered on the desired application surface.
  • a polymer containing preferably siloxane or amine group is used as the compatibilizer material.
  • microspheres (3) mixed into bitumen (2) are in the ratio of 20 to 50 preferably 30 percent by weight.
  • microspheres (3) are in between 50 to 300
  • micrometers The dimensions of microspheres (3) to be used are selected to be suitable for reflecting the rays in the desired radiation wavelength.
  • the insulation material (1 ) is used in a dishwasher (4).
  • the dishwasher (4) comprises a box shaped washing tub (5) with the front open, produced from metal and a cover (6) that closes the front face of the washing tub (5) and provides access therein.
  • the insulation material (1 ) at least partially surrounds the outer surface of the washing tub (5) ( Figure 2).
  • the cover (6) comprises a plate (7) produced from metal, facing the inner surface of the washing tub (5) and an outer cover (8) secured to the outer surface of the plate (7) and forming the portion viewed by the user from the outside.
  • the insulation material (1 ) is also disposed between the outer cover (8) and the plate (7). Accordingly, the heat loss through the cover (6) is provided to be minimized.
