本発明は低面圧用のクラッチフヱーシングとして好適な
摩擦材に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a friction material suitable as a clutch facing for low surface pressure.
従来この種の摩擦材は石綿を主体とし、これに例えばフ

無機塩類を混合して加熱加圧成型していたが、この方法
では摩擦材の摩擦係数を０．５以上にすることは困難で
あって、例えば２ｋ９／欲ないしはそれ以下の低面圧用
のクラッチフェーシングの目的には十分に沿い得ない。Conventionally, this type of friction material is mainly made of asbestos, mixed with friction performance improvers such as various modified products of phenolic resin, friction performance stabilizers such as phenol resin, and further mixed with inorganic salts and heated. Pressure molding was used, but with this method it is difficult to increase the friction coefficient of the friction material to 0.5 or higher, and it is not sufficient for the purpose of clutch facings for low surface pressures such as 2k9/lower or lower. I can't follow it.
本発明はこのような問題を解消するためになされたもの
で、摩擦係数が０．５以上と高く、耐摩耗性の良い摩擦
材を提供することを目的としたものである。本発明の摩
擦材が従来の摩擦材と異っている大きな点は皮屑と石綿
とコルクとを混在させた摩擦材配合を用い、かつ熱可塑
性樹脂（又は熱硬化性樹脂）を使用して摩擦材製品とし
ていることであり、これにより２ｋ９／鮒以下の低面圧
で使用する場合に摩擦係数が高く（０．５以上）、耐摩
耗性も優れているという効果が得られる。The present invention has been made to solve these problems, and aims to provide a friction material with a high coefficient of friction of 0.5 or more and good wear resistance. The major difference between the friction material of the present invention and conventional friction materials is that it uses a friction material composition that is a mixture of leather dregs, asbestos, and cork, and uses thermoplastic resin (or thermosetting resin). This is because it is a friction material product, and as a result, it has the effect of having a high friction coefficient (0.5 or more) and excellent wear resistance when used at a low surface pressure of 2k9/carp or less.
本発明の摩擦材を構成する基本配合の代表例としては皮
膚１〜６の重量％、石綿５〜５広重量％、コルク１０〜
５の重量％、繊維５〜３の重量％であり、これに５〜１
の重量％の熱可塑性樹脂又は熱硬化性樹脂を予め配合し
たものが用いられる。A typical example of the basic composition constituting the friction material of the present invention is skin 1-6% by weight, asbestos 5-5% by weight, cork 10-6% by weight.
5% by weight of fibers, 5% to 3% by weight of fibers, and 5% to 1% by weight of fibers.
% by weight of a thermoplastic resin or thermosetting resin is used.
上記配合において皮肩の添加量並びにコルクの添加量を
１〜６０％並びに１０〜５０％としたのは、１％並びに
１０％以下ではその添加効果がなく、又６０％並びに５
０％以上では添加増による向上効果が得られないからで
ある。In the above formulation, the amount of skin shoulder added and the amount of cork added were set to 1 to 60% and 10 to 50%, because if it was less than 1% or 10%, there would be no effect, and if it was less than 1% or 10%, there would be no effect.
This is because if it is 0% or more, no improvement effect can be obtained by increasing the addition amount.
又上記配合中の繊維としては例えばリンター等の植物繊

I can give it to you.

The above formulation was thoroughly mixed, weighed out, and heated and pressed in a predetermined mold at a pressure of 250 k9 or less according to a conventional method to obtain a friction material product.

ルクフェーシング及び石綿系フェーシングと本発明のフ
ェーシングとを定速型試験方法により性能の比較を行い
、添附図面の如き結果を得た。In order to further clarify the effects of the friction material of the present invention, performance comparisons were made between conventional cork facings, asbestos-based facings, and the facings of the present invention using a constant speed test method, and results were obtained as shown in the attached drawings.
尚上記試験条件はＶ＝７．５の／ｓ、Ｐ＝３ｋ９′めで
行った。The above test conditions were V=7.5/s and P=3k9'.
その結果、本発明品は従来の石綿系フヱーシングに比べ
て摩擦係数が高く、しかも従来品のコルクフェーシング
と異り、温度上昇によっても摩擦係数の変化が少なく高
温側の摩擦係数が従釆品に比べ顕著に優れているという
特徴を示した。又摩耗量については従来品の石綿系フェ
ーシングと比べてもそん色がないという利点をもってい
る。As a result, the product of the present invention has a higher coefficient of friction than conventional asbestos-based facings, and unlike conventional cork facings, the friction coefficient does not change much even when the temperature rises, and the friction coefficient on the high temperature side is similar to that of the subordinate product. It showed characteristics that are significantly superior compared to other methods. It also has the advantage that the amount of wear is comparable to that of conventional asbestos-based facings.
