The present invention relates to a dry sintered friction material having a high coefficient of friction, and more particularly to a dry sintered friction material for automobiles, industrial vehicles,
This invention relates to friction materials useful as brake lining materials, clutch facing materials, etc. for railway vehicles, etc. Conventionally, resin molds containing asbestos have been used as friction materials for vehicles, particularly for two-wheeled and four-wheeled vehicles, but in order to meet the current demands for pollution prevention, semi-metallic type materials containing metal fibers have been used. materials are becoming more widely used. However, this semi-metallic type friction material also has drawbacks, such as a decrease in the coefficient of friction during rain, and a decrease in the coefficient of friction due to carbonization of the resin under severe conditions such as high loads. Therefore, although sintered alloy-based friction materials have recently come to be used more and more, there is also a need for further improvements in performance. That is, automobiles are rapidly becoming smaller and lighter to save energy, and brake mechanisms and the like are also required to be smaller. In order to downsize brake mechanisms, new sintered friction materials with high friction coefficients and low wear are needed. The present invention was made to meet these demands, and includes (1) 45 to 65% by weight of copper, (2) 3 to 8% by weight of tin, (3) 3 to 15% by weight of graphite, (4) molybdenum disulfide,
0.5 to 5% by weight of at least one of tungsten disulfide, bismuth, and antimony, (5) 2 to 15% by weight of at least one of alumina, silica, mullite, silicon nitride, and zircon sand, and (6) rare earth element fluoride. and 5 to 30% by weight of at least one of oxides. According to the present invention, it is possible to obtain a sintered friction material that has excellent wear resistance, a high coefficient of friction, and whose coefficient of friction does not substantially decrease even when it rains. Each component of the sintered friction material of the present invention will be explained below. Since each of these components is mutually related and affects the physical properties of the friction material, it is not necessarily appropriate to discuss the reasons for each limitation individually, but the reasons for the limitations will be shown together. (1) Copper and (2) Tin These make up the base of friction materials, and are alloyed by sintering to form what is called a bronze base, increasing the strength of the base. Especially from the viewpoint of strength, copper is 45 to 65% by weight and tin is 3 to 8% by weight.
shall be. When tin is less than 3% by weight, sufficient strength to hold graphite and other non-metals cannot be obtained, while when it is more than 8% by weight, the friction material becomes brittle and its strength is reduced. (3) Graphite The addition of graphite mainly stabilizes the coefficient of friction. That is, in general, the frictional force generated between two surfaces of friction materials that slide against each other is (a) the force required to shear the adhesion that occurs in a part of the two surfaces, and (b) the force required to shear the adhesion that occurs on a part of the two surfaces, and (b) the force caused by the hard particles of the opposing material. It is said that this is due to the ability to revitalize the moat. By existing between these two surfaces, graphite controls adhesion that occurs between the two surfaces.
Therefore, the presence of an appropriate amount of graphite improves and stabilizes the friction coefficient of the friction material, and also improves the wear resistance. If the amount of graphite is less than 3% by weight, the above effects will not be sufficiently exhibited, whereas if it exceeds 15% by weight, the material strength will decrease and the coefficient of friction will decrease. (4) At least one of molybdenum disulfide, tungsten disulfide, bismuth, and antimony Molybdenum disulfide not only has the same effect as graphite, but also prevents so-called "squeal" and provides lubricity under high loads. It also has remarkable effects. The amount of molybdenum disulfide, etc. used is
The amount should be 0.5 to 5% by weight. The usage amount of these is 0.5
If it is less than 5% by weight, the effect of addition will not be sufficiently exhibited, while if it exceeds 5% by weight, the material strength and friction coefficient will decrease. (5) At least one of alumina, silica, mullite, silicon nitride, and zircon sand Alumina, etc., in the range of 2 to 15% by weight, not only produces the above-mentioned excavation effect, but also generates frictional heat on the mating sliding surface. By removing the oxide film that forms on the surface of the friction material, adhesion between the friction materials is stably generated and stable frictional force is exerted. If the amount used is less than 2% by weight, the above effects will not be fully exhibited, while if it exceeds 15% by weight, there is a tendency for the mating sliding surface to become rough. (6) At least one of rare earth element fluorides and oxides These compounds basically have the same effects as alumina, etc. However, these compounds have lower hardness than alumina and the like, so although their digging effect is inferior, they can remove the oxide film without significantly damaging the mating sliding surface. Therefore, in the range of 5 to 30% by weight, these compounds impart a stable and appropriate coefficient of friction to the friction material when used in combination with alumina or the like. If the amount of these compounds used is less than 5% by weight, it is difficult to achieve the desired effect, whereas if it exceeds 30% by weight, the friction material becomes brittle and wear increases. Specific examples of these compounds include fluorides such as cerium fluoride, lanthanum fluoride, yttrium fluoride, and samarium fluoride, and oxides such as lanthanum oxide, yttrium oxide, cerium oxide, and samarium oxide. Examples of the present invention will be shown below to further clarify the characteristics of the present invention. Example 1 57% by weight of copper powder, 5% by weight of tin powder, 9% by weight of graphite powder
% by weight, molybdenum disulfide powder 2% by weight, silica powder 4% by weight, mullite powder 3% by weight and cerium fluoride powder 20% by weight, and a molding pressure of 5 tons/
cm 2 , the molded body was stacked on a low carbon steel plate that had been previously plated with copper, and heated at 800°C in a nitrogen atmosphere for 7 days.
A sample was obtained by sintering while applying pressure at Kg/cm 2 to simultaneously perform sintering and bonding to a steel plate. The thus obtained sample was brought into sliding contact with the mating disk material (13 chrome steel) under the conditions of an inertia force of 1 Kg m sec 2 and an initial braking speed of 50 Km/hr (contact area 20 Km/hr).
cm 2 ), friction coefficient in dry state and wet state (water sprayed height), etc. were measured. The results are shown in Table 1. Comparative example 1 75% by weight of copper powder, 7% by weight of tin powder, 9% by weight of graphite powder
A sample in which a sintered body and a steel plate were joined in the same manner as in Example 1, except that a mixed powder consisting of 2% by weight of molybdenum disulfide powder, 4% by weight of silica powder, and 3% by weight of mullite powder was used. I got it. Table 1 shows the results of friction coefficients, etc., measured in the same manner as in Example 1.

The results are also shown in Table 2. However, when measuring the friction coefficient, the pressing force was 14.1 Kg/cm 2 .
