Conventionally, as a thermal insulation material for heat insulation and heat retention of exhaust pipes of ships, power plants, vehicles, etc., glass fiber is typically used. Glass fiber has excellent heat resistance, fire resistance, corrosion resistance, and electrical insulation, so it can be used without difficulty in high-temperature valves or pipes.

As a method for reinforcing the shortcomings of such glass fibers, the glass fiber workpiece is embedded and the outer surface of the glass fiber workpiece is reinforced with aluminum foil or coated cardboard. However, despite these efforts, it was difficult to install and use the insulating material made of glass fiber in the exhaust pipe. For example, when it is necessary to separate the insulating material from the exhaust pipe for repair of the exhaust pipe, when the insulating material is dismantled from the exhaust pipe, it is easily broken due to the weak durability of the aforementioned glass fiber, which makes reuse difficult, and replacement with a new insulating material there was In this case, the consumption cost of the insulating material increases, and a large amount of glass fiber waste is generated, which leads to a problem of environmental pollution.

In addition, since most of the conventional insulation materials are filled with only glass fiber for more than 90% as a material for insulation and insulation, there is a problem in that the efficiency of insulation and insulation is not high.

Accordingly, the present invention has led to the development of an insulating cover for an exhaust pipe of a power source, which can effectively heat and keep the exhaust pipe, increase the heat insulation and heat insulating effect of the exhaust pipe, and increase the service life.
