Definitions

  • the invention relates to a thermal and / or sound insulating product, based on mineral wool, such as glass wool, intended to be used in particular for the manufacture of insulating gaskets. These fittings allow acoustic and / or thermal insulation of the engine, or of the passenger compartment, of a vehicle.
  • the invention also relates to the method of manufacturing such a product and the method of manufacturing such a liner.
  • Phonic insulators made from foam-type materials, such as polyurethane or melamine foams, which attenuate sound through viscous losses, are known.
  • foams derived from petroleum products, are unecological and highly toxic in case of fire. They emit, in fact, volatile organic compounds commonly called VOCs. In addition, they have an auto-lift that is not satisfactory because of their low rigidity.
  • Glass Wool Automotive Green Mat which is in the form of a layer or layer of glass wool impregnated with a thermosetting binder at about 200 Formophenolic resin, having a basis weight between 400 and 1800 g / m 2 , in particular 425 g / m 2 .
  • This glass wool layer or batt is coated with polyester or polypropylene, and is fire-resistant or water and oil resistant. This type of product, uncooked, is used to manufacture insulating gaskets of vehicles, molded by thermo-compression.
  • the fiberglass web is produced in a forming line where the formed fibers are sprayed with phenol formaldehyde resin binder in a proportion of 10 to 26% by weight based on the weight of the final fiber product.
  • the fibers thus treated then fall at random and gather in the form of a tablecloth.
  • the dimensions of the glass fibers produced may vary within wide limits and have a diameter of less than 0.009 mm.
  • a 50 mm thick blank with a density of 16 g / dm 3 (ie 800 g / m 2 ) is cut from a sheet of glass fibers containing uncooked binder, and placed in a mold to be compressed to to reach a thickness of 6.4 mm after cooking.
