Embodiment 4

[0037] Example 4 included rubber compound B (see Table 3). Example 5 includes rubber compound C, embodiment 6 includes rubber compound D, embodiment 7 includes rubber compound E, embodiment 8 includes rubber compound F, embodiment 9 includes rubber compound G, embodiment 10 includes rubber compound H, comparative example 1 includes rubber compound I and comparative example 2 includes rubber compound J. Rubber mixtures B to J include raw material components, and the mixing amounts are shown in Table 1. Examples 4-10 and Comparative Examples 1 and 2 have the above-mentioned rubber mixture and other raw friction materials, and the mixing amount is shown in Table 2.

[0038] Therefore, Examples 1 to 3 each included the rubber compound A, and the addition amount of the rubber compound A was decreased in the order of Examples 1, 2 and 3.

[0039] Examples 1-3, 6-10 and Comparative Example 2 have mixtures A, D-H and J, respectively, and have silicone rubber (as non-ebony rubber), a...

Abstract

A friction material comprises a basic fiber, a friction regulation additive and an adhesive for bonding the basic fiber and the friction regulation additive. The adhesive is formed by rubber capable of ebonizing by sulfur and rubber not available of sulfur to ebonize.

Description

[0001] This application claims priority from Japanese Patent Application Serial No. 2006-2417, the contents of which are incorporated herein by reference. Background of the invention [0002] The present invention relates to friction materials such as brake linings or crutch facings, in particular it relates to friction materials comprising rubber as a binder. [0003] Various friction materials have hitherto been known, for example, friction materials using rubber as a binder are known. In the manufacturing method of the friction material, after base fibers, friction adjusting additives, and rubber are kneaded into a slurry, a sheet is then obtained from an extruder. Next, the sheet is cut to a desired size, bonded to a shoe such as a brake shoe, and then heat is applied, whereby the rubber is ebony with sulfur to obtain a hard friction Material. Therefore, the friction material using rubber as a binder can conform to the shape of, for example, a shoe of a brake pad. There...
