Definitions

• a known heat shield for motor vehicles consists of an aluminum sheet, a ceramic foam mat and an aluminum foil.
• the aluminum sheet serves as a carrier layer, the ceramic foam mat as thermal insulation and the aluminum foil as heat radiation-repellent, heat-resistant, mechanical protection of the sensitive ceramic mat.
• the sandwich-like structure of this heat shield is achieved by adhesion of the layers, for example by gluing.
• the implementation such as the chaining of these manufacturing operations, is associated with a lot of handling, which can be mastered either manually or by complex means of rationalization.
• the complex, multi-curved surfaces of such heat shields place high demands on the materials and tool construction, which can ultimately only be compensated for by high investment costs.
• the object of the present invention is to alleviate the disadvantages mentioned and to make the mentioned advantages of the heat shields accessible to smaller production series as well, by means of more rational construction and production.
• FIG. 1 shows a cross section through a heat shield with heat radiation-repellent, blank support layer made of metal sheet and a one-sided insulation layer,
• FIG. 2 shows a cross section through a heat shield with a support layer made of sheet metal and coated on one side and an insulation layer
• FIG. 3 shows a cross section through a heat shield with a support layer made of sheet metal coated on both sides and with an insulation layer on both sides,
• FIG. 4 shows a cross section through a heat shield with an insulation layer and two metal layers, one of which functions as a support layer and the other as a cover layer, and is each provided with a coating on one side.
• the heat shield 1 shown in FIG. 1 consists of a metal sheet, which is preferably made of aluminum and serves as a carrier layer 2 for the insulation layer 3 'adhering to it.
• the bare surface 10 of the carrier layer 2 is used as a mirror for rejecting the heat rays 20.
• the material for the insulation layer 3 1 condition organic and inorganic materials in question, which can be supplemented as required to influence the mechanical-thermal properties by bristles, fibers or flakes of various provinces. For example, the enrichment of the surface 10 of the insulation layer 3 '(see FIG. 2) with flakes made of silicon, which act like small scattering mirrors, without any noticeable increase in weight of the heat shield 1, the heat reflection of the insulation layer increase considerably.
• FIG. 3 Another thermal-mechanical parameter of the insulation is the density of the insulation layer 3 '. This can be adjusted by blowing gases into the ready-to-spread dough or into the ready-to-spray mass of the insulation 3, 3 ', 3 ", as by the metered admixture of powdered blowing agents.
• Figures 2 and 4 show the use of an adhesive , which is used for one-sided painting of the carrier layer 2 1. The double-sided use of adhesive is shown in FIG. 3, where the increased adhesion from the carrier layer 2 "benefits the connections with both insulation layers 3 1 and 3".
• a special, sandwich-like design finally shows FIG. 4, with two carrier layers 2 * treated on one side with adhesive and an insulation layer 3 arranged between these layers.
• the shape of the Heat shield before or after stacking is preformed, or with the layered insulation layer 3, 3 ', or 3" designed before full solidification.
• the insulation layer 3 for example, the physiologically completely harmless foam magnesium silicate is proposed, which is known as natural stone as "meerschaum” and has been valued since ancient times because of its excellent thermal-mechanical properties.
