Definitions
- the invention relates to a storage mat for storing an exhaust gas catalytic converter used for the cleaning of motor vehicle exhaust gases in a metallic catalytic converter housing.
- the storage mat is arranged on the circumference of the ceramic carrier body of an exhaust gas catalytic converter and seals the annular gap between the ceramic carrier body and the catalytic converter housing, which consists of a metallic material. It is intended to enable safe, vibration-free storage of the ceramic support body and must compensate for a change in the width of the annular gap to be sealed when the metallic catalyst housing expands at the operating temperature specified by the combustion exhaust gases.
- the storage mat also forms a thermal barrier coating on the inner wall of the catalytic converter housing and reduces the sound noise transmitted to the outside by the flowing exhaust gases.
- the storage mat consists of short inorganic fibers, an organic binder, and particulate inclusions made of an expanding material, for example mica or vermiculite, which expands under the action of heat and causes the storage mat to increase in volume at operating temperature.
- the inorganic fibers embedded in the binder consist of ceramic staple fibers or comminuted Si0 2 filaments with an average length of a few millimeters. (DE-U 93 11 571).
- a storage mat with short inorganic fibers tends to erode and Abrasion. Both fibers and particulate expandable material are discharged with the flowing combustion exhaust gases, with the result that the sealing of the annular gap becomes worse and the erosion increases.
- the invention has for its object to provide a storage mat for catalytic converters that is blow-out-proof and seals the annular gap between the catalytic converter and the catalyst housing well both at low and at high exhaust gas temperatures.
- a storage mat in the form of a binder-free, multi-layer fabric made of temperature-resistant threads, which is mechanically consolidated by stitching, wherein
- the threads consist of a crimped yarn made of filaments and are fixed by the stitching under tension in the fabric and the stitching is carried out with a sewing thread whose temperature resistance is lower than the operating temperature of the storage mat.
- the resulting crimped yarns are voluminous and are characterized by high elasticity.
- the threads consisting of a crimped yarn have been deposited under tension to form a flat structure which has a thickness which is customary for bearing mats.
- the threads are fixed within the fabric by quilting seams, while the tension is maintained.
- the sewing thread used for the stitching is made of a material whose temperature resistance is lower than the operating temperature of the storage mat.
- the storage mat according to the invention can thus be used in exhaust gas catalysts which are operated at relatively low temperatures, just as in exhaust gas catalysts for hot combustion exhaust gases, as are customary in gasoline engines. Since the storage mat according to the invention does not contain any particulate expanded materials or fiber fragments but instead consists exclusively of long filament threads, the risk of erosion or abrasion under the action of the flowing combustion exhaust gases is low.
- the crimped yarn preferably consists of Si0 2 filaments and / or filaments made of textile glass and / or AL 2 0 3 -containing inorganic filaments.
- other high-temperature-resistant crimped yarns made from organic or inorganic materials should not be excluded.
- the invention teaches that seams made of a temperature-resistant thread are provided on cut edges of the storage mat. The seams on the cut edges made of a temperature-resistant thread material ensure additional edge protection and contribute to a further improvement in the blow-out safety of the bearing mat according to the invention. Threads are suitable which still have sufficient tensile strength at the working temperature of the storage mat. Threads made of textile glass, Si0 2 , metals and the like come into question.
- the invention also relates to a method for producing the storage mat with the following features: a) crimped yarn made of temperature-resistant filaments is drawn off from rolls in several strands and placed under tension on a transport device moved transversely to the pull-off direction to form a flat, multi-layered flat structure.
- Fabric is released from the transport device.
- the invention teaches that mats are punched out of the continuous web, which is mechanically consolidated with quilting seams, and before or after the punching
- crimped yarn made of inorganic filaments is rolled in a plurality of strands 1 2 pulled off and placed under tension on a transport device 3 moved transversely to the pull-off direction to form a flat, multi-layered sheet-like structure 4.
- the strands 1 are hooked onto the edge-side chains 5 of the transport device 3. This maintains the tension in strands 1.
- the thickness of the fabric depends on the application. Depending on the diameter and weight of the catalyst for which the storage mat is intended, storage mats with a thickness of a few millimeters to a few centimeters are used. The thickness of the fabric is set up accordingly.
- the transport device 3 passes through a station 6, in which the fabric 4 is mechanically consolidated with stitching 7 so that the threads of the fabric continue to be under tension when the fabric 4 is released from the transport device 3.
- a sewing thread is used for the stitching seams 7, the temperature resistance of which is lower than the operating temperature of the storage mat.
- mats 8 are punched out of the continuous web, which is mechanically consolidated with quilting seams 7, seams 9 being made with a thread of temperature-resistant material in the area of the cut edges before or after the punching process.
- the material web mechanically consolidated with quilting seams can also first be rolled up to form an endless belt and the assembly into mats is carried out by the customer through punching operations elsewhere.
- binder-free storage mats for the storage of exhaust gas catalysts are produced. They consist of a multi-layer fabric made of inorganic threads, which is mechanically consolidated by stitching.
- the threads consist of a crimped yarn made of filaments and are fixed in the fabric by the stitching under tension and that the stitching is carried out with a sewing thread whose temperature resistance is lower than the operating temperature of the storage mat.
- the crimped yarn preferably consists of Si0 2 filaments and / or filaments made of textile glass and / or AL 2 0 3 -containing filaments.
- Synthetic sewing threads are used for the quilting seams, which are not heat-resistant and are destroyed when the storage mat is heated to working temperature. With the destruction of the sewing threads, deformation energy of the crimped yarn is released, whereby the volume of the storage mat increases and the sealing force of the storage mat clamped between the catalyst and the catalyst housing increases.
