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.
• Young's module that is to say the compression elastic module
• the tangent Delta, or tg o represents the factor of mechanical losses and expresses the dissipative characteristics of the material. It is measured in relation to the Young's modulus measurement.
• a material is all the more elastic the lower the value of the E 'module (ie the real part of Young's module) and it is more dissipative the higher the value of tg or
• Thermoplastic masses were prepared that were numbered from 1 to 5, the mass of example 1 corresponding to a typical mass prepared according to Spanish patent 554,644 and the masses of examples 2 to 5 to masses according to the invention.
• the sound pressure level is measured with the 0.8 mm steel plate, and then the one obtained if the complex formed by the steel plate, the absorbent (felt felt), is placed between both cabins 19 mm thick) and a sheet of 7 kg / m obtained according to the invention.
• the difference expressed in decibels, constitutes a measure of the sound insulation of the complex formed by the absorbent material and the soundproofing material tested.
• test sample is less in soundproofing than in examples ⁇ 2 to 5.
