のブレーキ用に用いられる摩擦摺動材(以下、単に摩擦
材と称す)に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a friction sliding material (hereinafter simply referred to as a friction material) used for brakes of vehicles such as automobiles and railways, and industrial machinery.
焼結摩擦摺動材は、従来摩擦構成材、潤滑剤および結合
剤としての金属配合材料を混合、成型した後高温還元雰
囲気中で焼結して製造していた。Sintered friction sliding materials have conventionally been manufactured by mixing and molding metal compound materials as friction constituent materials, lubricants, and binders, and then sintering the mixture in a high-temperature reducing atmosphere.
しかしこれらの各配合成分を単独のままで混合する際に

せることが困難で、摩擦材としての品質安定性維持上好
ましくなかった。However, when these ingredients are mixed individually, non-uniformity called segregation is unavoidable due to the difference in specific gravity of each ingredient and the attached shape. It was difficult to maintain this uniform dispersibility until the molding process, which was undesirable in terms of maintaining quality stability as a friction material.
本発明は、上述の問題点を解決するため成されたもので

である。The present invention has been made to solve the above-mentioned problems, and by pre-mixing the ingredients and granulating them, coating and bonding them with metal, the ingredients can be uniformly dispersed and between each single particle. The composition of each formulation was the same! The purpose of the present invention is to provide a friction material with uniform quality and excellent stability.

摺動材である。The present invention is made by bonding particles of mixed ingredients, and the particles have an average particle diameter of 005 to 3111111, and the particle surface is coated with metal, and the constituent material is metal powder and/or powder. This friction sliding material is characterized in that it uses carbonaceous material as a soil material and contains these components by volume of 10 to 90%.
本発明の摩擦材を製造するには、先ず粒子を構成する摩
擦構成材、潤滑剤等の配合成分を、比重差による分離偏
析の少ない、例えば湿式混練等により混合して均一分散
させた後、平均粒子径0.05〜3 mmの粒子に造粒
される。To manufacture the friction material of the present invention, first, the friction components, lubricant, and other ingredients constituting the particles are mixed and dispersed uniformly by, for example, wet kneading, which reduces separation and segregation due to differences in specific gravity. It is granulated into particles with an average particle diameter of 0.05 to 3 mm.
この場合平均粒子径0.0511m未満では結合材とし
ての金属被覆材料の比が犬となり、摩擦摺動材としての
性能が極限される。又3 Tlmを越えると結合粒子間
隙の比が犬となり、構造強度が低下する欠点を生じ易く
なる。In this case, if the average particle diameter is less than 0.0511 m, the ratio of the metal coating material as a binder will be too low, and the performance as a friction sliding material will be at its limit. Moreover, if it exceeds 3 Tlm, the ratio of the gaps between bonded particles becomes too large, which tends to cause the disadvantage that the structural strength decreases.
粒子はその表面に金属がめつき、メタリコン、蒸着等に
より被覆される。被覆する金属としては銅、銅系合金等
が用いられ、これにより、各粒子の破壊を防ぎ、後の結
合を容易にする。The surfaces of the particles are plated with metal and coated with metallization, vapor deposition, or the like. Copper, a copper-based alloy, or the like is used as the coating metal, which prevents each particle from breaking and facilitates subsequent bonding.
次に金属被覆された摩擦構成材、潤滑剤等を含む粒子は

還元性雰囲気下での焼結、銅ろう付け、或いは有機バイ
ンダー、無機バインダー(例、セラミックバインダー)
等による硬化結合などの方法のいずれによっても良い。The particles containing the metallized friction component, lubricant, etc. are then preformed in the presence or absence of other auxiliary binders and then subjected to a bonding process. This bonding process may be performed, for example, by sintering in a reducing atmosphere, by copper brazing, or by using organic or inorganic binders (e.g. ceramic binders).
Any method such as hard bonding according to et al.

ども含まれる。In the present invention, the metal powder used as the constituent material of the particles is a friction constituent material, and is made of, for example, copper, iron (steel), tin, titanium, chromium, nickel, or an alloy of these metals, and has a shape and shape. In addition to powders such as pulverized powder, atomized powder, and electrolytic powder, it also includes chopped fibers, cutting waste, etc.

不十分な金属被覆であが成り立たなくなる。In addition, the powdered carbonaceous material used as a constituent material of particles acts as a caking substance during particle formation, which is later solidified by high-temperature heating to form particles, and after solidification, a metal coating such as plating is formed on the surface. The capacitance of the constituent material, which also functions as a conductive material, is 10 to 90. These ingredients are 10
If the capacitance is less than 1, the conductivity during surface metal plating will be low.
Insufficient metal coating will make the process untenable.

There is no problem in containing the above, and there is also no problem in containing other inorganic or organic fillers and suitable binders.

摺動材を提供する利点がある。As described above, the friction sliding material of the present invention is made by bonding particles of mixed ingredients, and the particles have an average particle diameter of 0.05 to 3 mm and have metal-coated surfaces. Because the particles are formed and bonded without being destroyed while maintaining the ingredients uniformly dispersed within the single particles, the ingredients are the same between each single particle and the ingredients are distributed throughout the friction material. is uniformly dispersed, providing a friction material with uniform quality and excellent stability.Since it contains 10 to 90% of these components by volume, it provides a friction sliding material with a stable coefficient of friction without segregation of components. There are advantages to doing so.
