An exhaust system for an automobile is used to discharge exhaust gas discharged by the operation of an engine while reducing noise and pollution of the exhaust gas. When the exhaust gas is exhausted from the exhaust pipe system of the automobile, a large amount of heat carried by the exhaust gas heats the exhaust pipe, so that the surface temperature of the exhaust pipe reaches 500-600 ℃. Because the space of the automobile chassis is limited, parts around the automobile exhaust pipeline system are mostly close to the automobile exhaust pipeline, and the normal operation of the surrounding parts has strict requirements on the temperature, if the temperature is high, safety accidents are easily caused, so that the exhaust pipeline needs to be subjected to heat insulation treatment. There are two main heat-insulating treatment modes at home, one of which is to wrap the glass fiber by silica gel cloth, refractory cloth and other materials. The other method is to split the heat shield into two parts outside the exhaust pipe by means of cap nails or welding and the like. The exhaust pipe shield assembly wrapped by the soft refractory material has the defects of appearance wrinkles, poor heat insulation performance and the like. The existing heat shield is usually prepared by three-layer stamping and welding of a ceramic fiber plate and a metal plate, more metal materials are adopted, the weight of the product is larger, and the problem of falling off between the metal plate and the ceramic fiber plate is easy to occur, so that the failure of the heat shield is caused.
