The invention discloses a heat shield with long service life. The heat shield comprises a heat shield body and stainless steel wires. The heat shield body comprises high-temperature-resistant layers,a heat insulation cotton layer and a stainless steel foil layer, wherein the heat insulation cotton layer is located between the upper high-temperature-resistant layer and the lower high-temperature-resistant layer, the stainless steel foil layer is located on the other side of one high-temperature-resistant layer, and the stainless steel wires are located on the edge of the heat shield body and sew the high-temperature-resistant layers, the heat insulation cotton layer and the stainless steel foil layer together. The stainless steel foil layer with good abrasion resistance is arranged on thehigh-temperature-resistant layers, so that the situation that the high-temperature-resistant layers are rubbed and broken due to high-temperature oxidation and vibration of an engine is effectively avoided, and the good heat insulation performance of an exhaust pipe is guaranteed.
Description
【Technical field】 [0001] The invention relates to the technical field of heat shields, in particular to the technical field of heat shields with long service life. 【Background technique】 [0002] The automobile exhaust system is used to discharge the exhaust gas discharged by the engine, and at the same time reduce the noise and the pollution of the exhaust gas. When the exhaust pipe system of the automobile discharges the exhaust gas, a large amount of heat carried by the exhaust gas will heat the exhaust pipe, causing the surface temperature of the exhaust pipe to reach as high as 500-600 °C. Due to the limited space in the chassis of the car, the parts around the car exhaust pipeline system are mostly close to the car exhaust pipe, and the normal operation of the surrounding parts has strict requirements on the temperature. If the temperature is high, it is easy to cause safety hazards. accident, so the exhaust pipe needs to be insulated. At present, the above-mentioned...
