This invention concerns a kit (41) for reducing noise in motor vehicles and comprises at least one flat vehicle part (11) with a sound-insulating assembly package (42) consisting of several layers and an at least partly interlaying air layer (25). This assembly package (42) has at least one porous cushioning layer (13), a microporous reinforcing layer (14) which is lightweight, stiff and openly porous, an air flow resistance between Rt = 500Nsm and Rt = 2,500Nsm , and a surface area of mF = 0.3kg/m to mF = 2.0kg/m . The reinforcing layer (14) has a stiffness of B = 0.05Nm to B = 10.5Nm. This permits replacing the weight of classic spring-mass-systems for noise reduction in vehicles with a system at least 50 % lighter. In addition to the dampening effect on oscillations, this kit (41) also quite effectively absorbs sound and provides thermal insulation. Preferably, this multifunctional, ultralight kit (41) is used to insulate the floor or fire wall, or as door lining or roof inner lining.

The invention provides a structure comprising two facing plates, wherein the two facing plates are positioned one on each side of a solid-state composition, which solid-state composition comprises in the range of from 70 to 99% by weight of solid particles, and in the range of from 30 to 1% by weight of an asphaltenescontaining binder having a penetration of less than 15 dmm, based on total weight of solid-state composition, and a pre-fabricated double skin panel of use in constructing such a structure.

The invention relates to a method and a device for soundproofing oscillatory components such as sheet metal, by connecting a soundproofing coating (5) to the component (1), at least one intermediate layer (2) being applied between the soundproofing coating (5) and the oscillatory component (1). Said intermediate layer (2) is advantageously an especially elastomer adhesive layer which is applied, in a free-flowing state, for example by means of coextrusion, before the soundproofing coating (5) or at the same time. In this way, a material used for adhesion can be used as the intermediate layer and a material for acoustics can be used as the soundproofing material. The invention also relates to a corresponding coating and a device which automatically applies the coating, especially to sheet metal.

摘要:
Abdichtbahnen (14) dienen insbesondere zur Bildung von (Flach-)Dachabdeckungen. Die Abdichtbahnen (14) bestehen überwiegend aus brennbarem Bitumen. Es ist deshalb erforderlich, die Abdichtbahn (14) so auszubilden, daß sie nicht brennt oder ein Brand derselben innerhalb kurzer Zeit erstickt wird. Die erfindungsgemäße Abdichtbahn (14) verfügt über wenigstens eine gelochte oder gitterartige Brandschutzschicht (18). Durch diese kann im Brandfall das brennbare Bitumen nach unten abfließen, wobei die Flammen an der Brandschutzschicht (18) zurückgehalten werden. Dabei erlischt der Brand automatisch nach dem Abfließen des gesamten Bitumens durch die gelochte oder gitterartige Brandschutzschicht (18).
摘要:
Disclosed is a damping member comprising, as main components, a petroleum resin, asphalt and mica. By selecting and using mica as the filler and incorporating mica in an amount smaller than the amount of asphalt, the adhesion follow-up property to a substrate can be improved. This damping material can be attached simply and assuredly to a substrate having a curved surface, such as a tube or pipe, an air-conditioning duct or a part of a building or vehicle by heat-pressing or heat-fusion-bonding, and a product having an excellent damping effect is provided.
摘要:
The invention pertains to a reinforced covering material, comprising a reinforcement layer with apertures therein, and a polyurethane-based layer comprising 20 - 100 % of thermosetting polyurethane, based on the weight of that layer, which polyurethane- based layer is arranged at least one side of the reinforcement layer and extends through the apertures. It may be used to provide weather- and water-proofing in construction materials, e.g. as lead flashings or in/on roofs, bridges and tunnels.
