件において非常に厳しい環境下に置かれる。Conventionally, a generally known disk pad is formed by joining a pad which is a friction material on a backing metal, pressing a rotating disk with the pad and stopping the rotation of the disk by the frictional force. In this case, the driving of the automobile is stopped. In this case, the disk pad is not only subjected to a strong shearing force and frictional heat, but also exposed directly to the outside air, so that it is affected by wind and rain and a snow melting agent such as NaCl and CaCl 2. Is subjected to a very severe environment in mechanical strength and corrosive conditions.
【０００４】一方、ディスクブレーキは安全上万一の故

にパッドと裏金の接着面は絶対破断することのない接着
強度を有する必要がある。[0004] On the other hand, a disc brake is one in which a failure is not tolerated for safety reasons, and in particular, the bonding surface between the pad and the back metal of the disk pad needs to have an adhesive strength that never breaks.

生する危険があった。For this reason, conventionally, an uneven portion is formed by shots on the surface of the back metal to mechanically strengthen the adhesive force with the pad. However, this method is effective as long as the brake is new.However, if the brake is used for a long period of time, or when traveling on a salty road in a cold area, rust will be generated in the boss hole of the backing metal, There is a danger that a brake failure may occur when the vehicle is running due to the peeling of the pad and the back metal and a decrease in the adhesive strength, and finally an accident may occur.

No. 4836 discloses a method. Hereinafter, description will be made in order.

あった。[0007] JP-B-57-45939 discloses that a triiron tetroxide layer having a thickness of 0.1 to 5.0 µm is formed on the surface of a back metal. However, this method has a drawback that it is not possible to obtain a remarkable rust prevention effect that satisfies the reliability required for the disk pad.

However, this method has the drawback that the process becomes complicated, and that no remarkable effects can be obtained in terms of cost and rust prevention.

It has been disclosed. However, this chromic acid treatment liquid has drawbacks that it is difficult to handle from the viewpoint of safety, hygiene and pollution, and that it is expensive.

着剤に防錆効果を期待するのは困難であった。As described above, various methods have been proposed to prevent rust generated between the back metal and the pad. However, it is difficult to obtain a rust-preventive effect that can withstand the reliability required of the disc pad by any of the methods, and even if it is obtained, there is a problem in terms of safety, health, pollution, and cost. was there. Further, in the conventional disk pad, the back metal and the friction material are integrally formed via an adhesive. Since the adhesive is stretched by heat and pressure during molding of the friction material and is absorbed by the friction material, the thickness cannot be substantially specified. Even if the thickness of the adhesive is increased, the same applies because the adhesive has fluidity until it is cured. Therefore, it has been difficult to expect the adhesive to have a rust-preventive effect with the conventional disk pad.

A resin powder such as epoxy which becomes the organic film 2 is powder-coated on the surface of the substrate by an electrostatic spraying method. 18 base metal on an experimental basis
By heating to 0 ° C. and spraying the powder resin through a 100 mesh wire netting, an organic film having a predetermined thickness can be obtained. Thereafter, a heat treatment is performed at 180 ° C. for 1 hour to complete the cured organic film 2. A phenolic resin adhesive is applied to the organic film 2, dried at 80 ° C. for 30 minutes, and integrally molded with the friction base material 4 in a mold at 160 ° C.
Heat treatment for 0 hour to obtain a disk pad. The organic film 2 is not limited to phenol resin, but may be epoxy, melamine,
Acrylic, thermosetting resin, or rubber phenol powder may be used. It is conceivable to add a filler and a colorant to these organic substances, but it is more preferable to add no. It is desirable that the same material as the organic film 2 or a similar material be used for the adhesive 2. This is because the bonding strength between the organic film 2 and the adhesive is improved by using the same material or a similar material. The thickness of the organic film 2 is
If it is 5 μm or more, considerable rust-preventive hardening can be obtained, preferably 10 μm, more preferably 15 μm or more.

Example 3 is 11 μm. In Comparative Example 1, a back metal made of SAPH was subjected to a soft nitriding treatment, and a phenol resin adhesive was directly applied thereon and dried to form a 20 μm adhesive film, which was integrally formed with a friction base material. In Comparative Example 2, after cleaning the back metal made of SAPH with trichlorene, a triiron tetroxide layer was formed on the surface thereof at 4 μm.
The same processing as in Comparative Example 1 was performed.

It can be seen that the rust-preventing power of Examples 1 to 3 increases as the thickness of the organic film 2 increases.
Further, as a result of cutting the disk pad of Example 1 and observing it with a microscope, it was found that an organic film of about 25 μm was formed on the entire surface. In other words, the organic film is hardly affected by heat and pressure during integral molding with the friction base material. However, in Comparative Examples 1 and 2, a film having a clear thickness could not be observed.
