Definitions
- the present invention relates to a friction material used for disc brake pads and brake shoes of automobiles and the like.
- disc brakes and drum brakes have been used as braking devices for automobiles, etc.
- disc brake pads and brake shoes in which a friction material is bonded to a metal base member such as steel are used as friction members. ing.
- the friction material includes a semi-metallic friction material containing 30% by weight or more and less than 60% by weight of steel fiber as a fiber base material, and steel fiber in a part of the fiber base material. Is classified into low steel friction material containing less than 30% by weight of the total friction material composition and NAO (Non-Asbestos-Organic) material that does not contain steel fibers such as steel fibers and stainless steel as the fiber base material. Yes.
- NAO Non-Asbestos-Organic
- Friction members that use NAO friction materials which are made of a combination of these materials, and friction modifiers such as organic fillers, inorganic fillers, inorganic abrasives, lubricants, and metal particles, have come to be widely used. ing.
- aramid fibers are widely used as organic fibers, cashew dust as organic fillers, and barium sulfate as inorganic fillers. These raw materials are used in the presence of water. Since sulfate ions that cause rusting may be eluted, the disc rotor, which is the mating material of the disc brake, which is the mating material of the friction material, and the brake drum, which is the mating material of the drum brake, are rusted. It is easy to generate.
- the NAO friction material when used for a disc brake or drum brake equipped with a parking mechanism, the disc rotor or brake drum and the friction material are fixed by rust after being left for a long time in the parking state. There is a problem that so-called rust fixation tends to occur.
- an alkali metal salt may be added to the friction material as a pH adjuster.
- Patent Document 1 describes a friction material formed by heating and pressing a friction material composition containing 0.2 to 5% by weight of an alkali metal salt in the entire composition.
- Patent Document 2 discloses a friction material including a filler, a binder made of a resin, a fiber reinforcing material, and a friction modifier, and the filler is made of activated carbon particles having an average particle diameter of approximately 2 mm. There is described a friction material that contains a granular material and suppresses a decrease in a friction coefficient due to a gas generated at the time of a fade phenomenon and exhibits a sufficient braking force. Note that Patent Document 2 has no description regarding the problem of rust fixation.
- a friction material comprising a fiber base material, a binder, and a friction modifier, and formed from a friction material composition of NAO material containing at least one raw material that elutes sulfate ions, while ensuring good wear resistance.
- An object of the present invention is to provide a friction material in which rust fixation is suppressed.
- activated carbon has the property of adsorbing many materials in its fine holes, and it adsorbs gases such as nitrate ions and sulfate ions generated from the friction material during the fade phenomenon.
- the surface is non-polar, and polar molecules with a small molecular weight such as water are difficult to adsorb. Therefore, the friction material obtained by blending such activated carbon with the friction material composition does not show the effect of suppressing rust fixation.
- hydrophilic activated carbon is known in which the surface is modified by acid treatment with hydrochloric acid, sulfuric acid or the like to impart hydrophilicity.
- Hydrophilic activated carbon has good moisture adsorption, but its surface is acidic, and it is thought that it promotes rusting of the counterpart material, and has not been used for friction materials.
- hydrophilic activated carbon which was thought to promote rusting of the counterpart material, was added to the friction material composition, the hydrophilic activated carbon sufficiently adsorbed sulfate ions and moisture, and conversely, rust fixation could be suppressed. I found out.
- the present invention is a friction material comprising a fiber base material, a binder, and a friction modifier, and formed by molding a friction material composition of NAO material containing at least one raw material that elutes sulfate ions.
- a specific amount of hydrophilic activated carbon is blended in the part and is based on the following technique.
- a friction material composed of a fiber base material, a binder, and a friction modifier, and formed by molding a friction material composition of NAO material containing at least one raw material that elutes sulfate ions.
- a friction material comprising hydrophilic activated carbon as an adjustment material.
- a friction material composed of a fiber base material, a binder, and a friction modifier, and formed by molding a friction material composition of NAO material containing at least one raw material that elutes sulfate ions, has good resistance. It is possible to provide a friction material in which rust fixation is suppressed while ensuring wearability.
- FIG. 1 is a diagram showing an example of a manufacturing process of a disc brake pad using the friction material of the present invention.
- FIG. 2 is a perspective view showing an example of a disc brake pad using the friction material of the present invention.
- FIG. 3 is a diagram showing an example of a manufacturing process of a brake shoe using the friction material of the present invention.
- FIG. 4 is a perspective view showing an example of a brake shoe using the friction material of the present invention.
- a friction material comprising a fiber base material, a binder, and a friction modifier, and formed by molding a friction material composition of NAO material containing at least one raw material that elutes sulfate ions. Part of it is blended with hydrophilic activated carbon.
- the hydrophilic activated carbon is obtained by treating activated carbon with an acid such as sulfuric acid or hydrochloric acid to form an oxide on the surface.
- the hydrophilic activated carbon is preferably blended in an amount of 0.4 to 5% by weight based on the total amount of the friction material composition.
- the blending amount of hydrophilic activated carbon is 0.4% by weight or more with respect to the total amount of the friction material composition, a sufficient effect of suppressing rust fixation can be obtained, and the blending amount of hydrophilic activated carbon is the total amount of the friction material composition. On the other hand, if it is 5% by weight or less, necessary wear resistance can be ensured.
- the average particle diameter of the hydrophilic activated carbon is preferably 80 to 200 ⁇ m. If it is this range, the rust sticking inhibitory effect will improve more and abrasion resistance will become more favorable.
- a hydrophilic phenol resin as a binder is added in an amount of 8 to 12% by weight based on the total amount of the friction material composition.
- the blending amount of the hydrophilic phenol resin is in the range of 8 to 12% by weight with respect to the total amount of the friction material composition, the effect of suppressing rust fixation is further improved.
- hydrophilic phenol resin examples include straight phenol resins and phenol resins modified with a hydrophilic elastomer such as NBR and acrylic rubber. Since phenolic resin modified with silicone and phenolic resin in which fluoropolymer is dispersed have water repellency, when the wear powder is adsorbed on activated carbon, it becomes difficult for activated carbon to adsorb moisture, further increasing the effect of inhibiting rust fixation. I cannot expect improvement.
- the friction material of the present invention includes, in addition to the above-mentioned hydrophilic activated carbon and hydrophilic phenol resin, fiber base materials such as metal fibers, organic fibers, and inorganic fibers used in ordinary friction materials, and thermosetting. It consists of a friction material composition including a binder such as a resin and a friction modifier such as an organic filler, an inorganic filler, an inorganic abrasive, a lubricant, and metal particles.
- the fiber base material examples include metal fibers such as copper fibers and brass fibers excluding steel fibers, organic fibers such as aramid fibers and acrylic fibers, and inorganic fibers such as carbon fibers, ceramic fibers, and rock wool.

- binder examples include phenol resins, resins obtained by modifying phenol resins with cashew oil, silicone oil, various elastomers, and the like, resins obtained by dispersing various elastomers, fluoropolymers, and the like in phenol resins.
- the binder content is preferably 9 to 15% by weight with respect to the total amount of the friction material composition in order to ensure sufficient mechanical strength and wear resistance.
- 8 to 12% by weight of a straight phenol resin or a phenol resin modified with a hydrophilic elastomer such as NBR or acrylic rubber is contained in the total amount of the friction material composition. More preferred.
- friction modifiers other than the hydrophilic activated carbon described above include organic fillers such as cashew dust, tire tread rubber pulverized powder, various unvulcanized rubber particles, various vulcanized rubber particles, barium sulfate, calcium hydroxide , Inorganic fillers such as vermiculite and mica, inorganic abrasives such as iron oxide, aluminum oxide, zirconium silicate and magnesium oxide, lubricants such as graphite, coke and metal sulfide, tin particles and zinc particles A metal particle is mentioned.
- the content of the friction modifier is preferably 60 to 90% by weight based on the total amount of the friction material composition, depending on the desired friction characteristics.
- Fiber base materials can be used in appropriate combinations according to desired quality, mechanical characteristics, and friction and wear characteristics.
