Definitions

  • the present invention has as its object thermoplastic masses as well as laminated and laminated materials obtained therefrom, which have insulating and vibration insulating properties and which can be used, in particular, in the dividing wall between the mo ⁇ tor and the passenger compartment of an automotive vehicle, such as a passenger car, and, in general, in other places of cars, trains, airplanes, etc., as well as on walls, floors, ceilings, and roofs metallic buildings and in household appliances and industrial machines (in these last two cases for their vibration damping properties).
  • Said Spanish patent protects the exclusive for the production of a thermoplastic mass consisting of chlorinated polyethylene, mixed with an oil, which can be replaced by a plasticizer, and fillers.
  • a thermoplastic mass consisting of chlorinated polyethylene, mixed with an oil, which can be replaced by a plasticizer, and fillers.
  • thermoplastic mass, and laminated and laminated materials obtained from it, that are suitable for the aforementioned applications, and particularly for the dividing wall between the engine and the interior of a car, must have :
  • thermoplastic mass is constituted between 0.6 and 50% chlorinated polyethylene; between 20 and 95% of a load material; and between 4 and 60% of said extender component; containing the mass in addition to minor components, in order to adapt to the intended purpose the physical properties, both of the total mass and of some of the constituents; particularly, the value of "fogging" (release of volatile materials), measured according to standard 75201, is optimal.
  • thermoplastic mass is laminated, alone or in conjunction with an absorbent material, located in any position and / or in one or several layers, to give a laminated or laminated material, which is then placed in the intended place.

Abstract

Masse thermoplastique pour des applications d'insonorisation et d'amortissement des vibrations et matériaux laminés et stratifiés obtenus à partir de celle-ci, en particulier pour véhicules automobiles; cette masse est constituée de: 0,6 à 50 % de polyéthylène chloré; 20 à 95 % de matériau de charge; et 4 à 60 % d'un composant d'étalement, ce composant d'étalement étant choisi de sorte que la compatibilité avec le polyéthylène chloré est maintenue, cette compatibilité étant définie par un point d'aniline ayant des valeurs inférieures à 100 °C. Cette masse est utilisée pour produire des matériaux laminés et stratifiés destinés à être montés dans des véhicules automobiles ainsi que dans des édifices et des appareils électroménagers et des machines industrielles, à des fins d'insonorisation et d'amortissement des vibrations.
