【発明の詳細な説明】
本発明は最寿命の低面圧用のクラッチフェーシングとし
て好適な石綿を使用しない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 that does not use asbestos and is suitable as a clutch facing for low surface pressure applications with the longest life.
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１【９／地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沿い得ない。又
従来品としてコルク材によるものがあるが、これは摩耗
が早く、使用中摩擦係数が低下し、かつクラッチに接続
する際のノイズも大きいという欠点があった。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. However, 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 of, for example, 1 [9/2] or less. I can't follow it. In addition, there is a conventional product made of cork material, but this has the drawbacks of rapid wear, a decrease in the coefficient of friction during use, and high noise when connected to a clutch.
本発明はこのような欠点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、石綿を使用しないで
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。The present invention was made to eliminate these drawbacks, and aims to provide a friction material with a high friction coefficient of 0.5 or more and good wear resistance without using asbestos. .
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
皮粉末と岩綿、植物繊維素とを混在させた摩擦材配合を
用い、かつ摩擦調整剤及び熱硬化性樹脂の存在下に加熱
加圧成形することによって摩擦材製品としていることで
あり、これにより２ｋ９ノの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 major difference between the friction material of the present invention and conventional friction materials is that it uses a friction material formulation that is a mixture of leather powder, rock wool, and vegetable cellulose, and that it uses a friction modifier and a thermosetting resin. It is made into a friction material product by heating and press-molding it, and as a result, it has a high coefficient of friction (0.5 or more) and excellent wear resistance when used at low surface pressures of 2k9 or less. This effect can be obtained.
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
粉末１〜６の重量％、岩綿５〜５０重量％、植物繊維素
１０〜５の重量％であり、これに１〜１の重量％の熱硬
化性樹脂を予め配合するか或いは熱硬化性樹脂を除く上
記の配合を一たん抄紙してからこれに熱硬化性樹脂を浸
潤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 1 to 6% by weight of leather powder, 5 to 50% by weight of rock wool, 10 to 5% by weight of vegetable cellulose, and 1 to 1% by weight of vegetable cellulose. Either % by weight of a thermosetting resin is blended in advance, or the above-mentioned composition excluding the thermosetting resin is once made into paper and then the thermosetting resin is infiltrated into the paper.
上記配合において皮粉末の添加量並びに岩綿の添加量を
１〜６０％並びに５〜５０％としたのは、１％並びに５
％以下ではその添加効果がなく、又６０％並びに５０％
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 leather powder added and the amount of rock wool added were 1 to 60% and 5 to 50%.
% or less, there is no effect of addition, and 60% and 50%
This is because the improvement effect by increasing the amount added cannot be obtained.
上記本発明の摩擦材の耐摩耗性は従来品の１び音程度に
も向上し、しかも摩擦係数は従来品より高く安定してい
る。The abrasion resistance of the friction material of the present invention is improved by one degree compared to the conventional product, and the friction coefficient is higher and more stable than the conventional product.
その上クラッチ接続時のノイズがなく、摩擦時に臭の発
生がなく、又高温時の性能も従来品より優れている等の
利点をもっている。以下に本発明の実施例を示す。In addition, it has the advantages of no noise when the clutch is connected, no odor during friction, and better performance at high temperatures than conventional products. Examples of the present invention are shown below.

っている。As a result, the product 1 of the present invention has a higher friction coefficient than the conventional asbestos-based facing 3, and unlike the conventional cork facing 2, the friction coefficient does not change much even when the temperature rises, and the friction coefficient on the high temperature side is lower than that of the conventional product. It had the characteristic of being significantly superior to other products. In addition, it has the advantage that the amount of friction is comparable to that of the conventional asbestos-based facing 3.
