Embodiment

[0035] Hereinafter, the present invention will be specifically described based on examples. However, the present invention is not limited thereto.

[0036] In this example, according to figure 1 The friction material raw materials were mixed in the indicated compounding amounts to obtain the friction material compositions of Examples 1-13 and Comparative Examples 1-7. In addition, the unit of the compounding quantity of each friction material raw material in a table is weight% with respect to the whole friction material composition. The friction material composition was mixed for 10 minutes using a Lodige mixer, and the mixture was molded at a molding temperature of 160°C and a molding pressure of 200kgf / cm 2 , The molding time is 10 minutes under pressure and heating. Next, the molding was cured at 200° C. for 4 hours.

[0037] The following items were evaluated about the friction materials of Examples 1-12 and Comparative Examples 1-7 which were produced.

[0038] (rust...

Abstract

A non-asbestos friction material containing a fibrous substrate, a binder, and a friction modifier, wherein said material contains no copper components, carbonaceous raw materials, and metal sulfides but does contain an inorganic material having a laminar crystal structure and differing from the above copper components, carbonaceous raw materials, and metal sulfides. At least one inorganic material selected from titanates, talc, kaolin, mica, vermiculite, and smectite is preferably used as the above inorganic material.

Description

technical field [0001] The present invention relates to an asbestos-free friction material used, for example, in a disc brake with a parking mechanism for a vehicle. Background technique [0002] Conventionally, for example, when a disc brake with a parking mechanism is left with the parking brake activated for a long period of time and the friction material is pressed against the rotor for a long period of time, the rotor and the friction material may adhere due to rust. Such a phenomenon is generally called rust adhesion, and as a technique for suppressing this rust adhesion, for example, the technique described in Patent Document 1 is known. [0003] In the above-mentioned document, improvement of wear resistance and rust resistance adhesion is achieved by using a friction material composition containing a specific amount of Bonding materials, organic fibers, metal sulfide lubricants as lubricants, carbon lubricants, titanates, wollastonite as inorganic friction regulato...
