Description of the Related Art Since an automobile muffler is exposed to a road deicing agent such as rock salt on the outside and exposed to high-temperature exhaust gas on the outside, an aluminum plated steel sheet or a stainless steel sheet which is mainly excellent in corrosion resistance and heat resistance is conventionally used. in use. However, since the catalyst converter has been incorporated into the exhaust system of the muffler, the temperature and composition of the exhaust gas have changed and the inside of the muffler has been significantly corroded.

樹脂を用いていた。Therefore, the inventors of the present invention, as a corrosion-resistant muffler material, firstly (1) form a heat-resistant transparent silicone resin coating film on the surface to a thin thickness of 0.5 to 2 μm to obtain heat resistance and spots. Silicone resin-coated aluminum-plated steel sheet having weldability (Japanese Patent Laid-Open No. 172640/1988) or (2) Aluminum powder is added to the silicone resin as a conductive agent to thicken the coating film to 3 to 10 μm. Even so, a silicone resin-coated aluminum-based plated steel sheet (JP-A-2-265742) having spot weldability was proposed. In these pre-coated steel sheets, as the silicone resin, the general formula R

問題があった。However, the precoated steel sheet (1) has a thin coating film to secure spot weldability.
Corrosion resistance and heat resistance were insufficient. On the other hand, the precoated steel sheet (2) does not have such a problem, but when the conductive agent is aluminum powder, there is a problem in spot weldability.
Further, the muffler has a strong color tone of black, but since both of the precoated steel sheets have a transparent coating film or contain aluminum powder, the muffler can be produced only in a silver-colored appearance. . A black pigment may be added to the coating film to give a black color tone, but since ordinary pigments such as carbon black have poor heat resistance, the coating film peels off when used at high temperatures for a long time. There was a problem of causing.

It was found that the composite oxide powder of Cu, Fe, and Mn can be colored black without impairing the spot weldability, and that the heat-resistant coating film adhesion can be improved more than that of carbon black.

接部を損傷する。Here, the nickel powder is spherical,
Particle size distribution of 2 to 40 μm (average particle size of 5 to 15 μm
m) is used. There are other scales of nickel powder, but scales cause more sparks during welding than spherical scales. Also, the particle size distribution is 2μ
Manufacturing powders less than m is difficult or expensive. vice versa,
If it exceeds 40 μm, the adhesion of the coating film decreases and the spark during welding increases. The compounding amount is 20 to 40 parts by weight per 100 parts by weight of the organopolysiloxane resin.
If the amount is less than 20 parts by weight, the spot weldability is inferior and 40
If it exceeds the weight part, the spark during welding becomes large and the weld part is damaged.

Add 0 to 30 parts by weight. This is because when it is less than 10 parts by weight, when the coating film thickness is 4 μm, the hiding power becomes insufficient and the desired blackness cannot be obtained, and when it exceeds 30 parts by weight, the coating film adhesion decreases. Because. Coating thickness is 4μ
If it is less than m, the hiding power and corrosion resistance will be weak, and if it exceeds 12 μm, the coating film adhesion will be poor, so it is set to 4 to 12 μm.
Further, if the complex oxide powder and the coating film thickness are within the above ranges, for example, if aluminum powder or the like is added to the conductive agent instead of nickel powder, a metallic feeling is produced and the desired blackness cannot be obtained.
