Description

本発明の摩擦材は、造粒物Ａからなる層Ａと造粒物Ｂからなる層Ｂを積層したものを一体に硬化してなり、該層Ａを摩擦面側に設置した摩擦材であって、該造粒物Ａ及び造粒物Ｂが、それぞれ少なくとも繊維基材、結合材及び摩擦調整材を含み、該造粒物Ａの結合材比率Ａ（質量比）と該造粒物Ｂの結合材比率Ｂ（質量比）が、結合材比率Ａ／結合材比率Ｂ＝１／５〜１／２であることを特徴とする。
本発明の摩擦材の製造方法は、バックプレート上に上記層Ａ及び層Ｂを積層したものを加熱加圧成形する。
本発明において、バックプレートとは、例えば、ディスク用ブレーキのプレッシャプレートやドラム用ライニングのシューリムを言う。 The friction material of the present invention is a friction material in which a layer A made of a granulated product A and a layer B made of a granulated product B are laminated, and the layer A is installed on the friction surface side. Te, granulation product a and granulation product B is at least fibrous substrate respectively, seen containing a binder and a friction modifier, a binder ratio a (mass ratio) of the granulated product a and the granulated product B binding material ratio B (mass ratio), wherein the binder ratio a / binder ratio B = 1 / 5~1 / 2 der Turkey.
Method for producing a friction material of the present invention, a material obtained by laminating the layer A and the layer B is molded under heat pressure to the back plate.
In the present invention, the back plate refers to, for example, a pressure plate for a disc brake or a shoe rim for a drum lining.

本発明の摩擦材を製造するには、バックプレート上に造粒物Ａからなる層Ａと造粒物Ｂからなる層Ｂを積層したものを加熱加圧成形することができる。所望により成形後、研磨等の処理を施すことができる。
上記加熱、加圧条件は、造粒物組成等に応じて適宜設定することができる。
上記積層は通常、バックプレート上に形成されるが、所望によりそれ以外の基板、例えば、硬化後に容易に剥離可能な基板に積層を形成し、硬化後、硬化物を剥離し、摩擦材としてもよい。また、この剥離した摩擦材と造粒物Ｂを用いてバックプレートに接着することもできる。 In order to produce the friction material of the present invention, a layer obtained by laminating the layer A composed of the granulated product A and the layer B composed of the granulated product B on the back plate can be heated and pressed . If desired, a treatment such as polishing can be performed after molding.
The heating and pressurizing conditions can be appropriately set according to the granule composition and the like.
The above laminate is usually formed on a back plate, but if desired, the laminate is formed on another substrate, for example, a substrate that can be easily peeled after curing, and after curing, the cured product is peeled off and used as a friction material. Good. Further, the peeled friction material and the granulated product B can be used to adhere to the back plate.

Claims
