題である。[Problem to be Solved by the Invention 1] In such conventional PTFE sliding materials to which an inorganic filler such as glass fiber powder or a solid lubricant is added, the wear resistance of the sliding material itself is not sufficiently satisfactory. In addition, even if wear resistance is sufficient, soft shafts that are mating materials, especially soft shafts made of unhardened steel, aluminum, SUS, etc., may be damaged by abrasion powder from the sliding material. It has the disadvantage of causing wear. Conventionally, additives that do not cause wear on soft shafts exist, but they have problems with toxicity, cost, and handling. Furthermore, there is a problem of "F-squeak" which is a sliding sound generated by the behavior of abrasion powder during use. It is an object of the present invention to solve the above problems.

人手も簡単であり毒性についても問題はない。The main problems can be solved by the methods described above. However, even with the sliding material of the present invention, abnormal noise is generated during sliding depending on the conditions of use, and this "squeak" may become a problem during use. In order to prevent this, a special phenolic resin powder was found among many substances as an effective filler, and it was found that the addition of this powder could solve the problem of noise generation. This special phenolic resin powder is also commercially available.
It is easy to use manually and there are no problems with toxicity.

的強度を著しく低下させる。When the PTFE resin-based sliding material contains iron oxide powder in this proportion, it is effective in improving the wear resistance of the sliding material itself. If the amount of iron oxide powder is less than 0.1% by weight, this effect will not occur. Moreover, if the iron oxide powder exceeds 10% by weight, the mechanical strength of the sliding material will be significantly reduced.
（２）平均粒径１〜１０ μｍの酸化鉄粉末の添加量を
０．１〜１０重量％とする点について。(2) Regarding the point that the amount of iron oxide powder with an average particle size of 1 to 10 μm is 0.1 to 10% by weight.

的強度を著しく低下させる。When the PTFE resin-based sliding material contains iron oxide powder of this particle size and content, it is effective against the wear of the mating shaft, especially the soft shaft, and is also effective in improving the wear resistance of the sliding material itself. If the iron oxide powder of this particle size is less than 0.1% by weight, no effect on wear resistance will be produced. Moreover, if it exceeds 10% by weight, the mechanical strength of the sliding material will be significantly reduced.

ると、摺動材の機械的強度を著しく低下させる。PTFE resin-based sliding material When this amount of special phenolic resin powder is added, it is effective in preventing the generation of abnormal noise called "squeak" during sliding and in lowering the coefficient of friction. If the special phenol resin powder is less than 0.1% by weight, it will not be effective in preventing noise generation or reducing the coefficient of friction, and if it exceeds 20% by weight, the mechanical strength of the sliding material will be significantly reduced.

If the special phenol resin powder is less than 0.1% by weight, it will not be effective in preventing noise generation or lowering the coefficient of friction.
If it exceeds 0% by weight, the mechanical strength of the sliding material will be significantly reduced.

The mixed powder was put into a mold, and after compression molding, it was heated and fired at 370° C. for 13 hours to form a molded body. A test piece for tensile and elongation measurements and a cylindrical bearing for friction and wear tests were fabricated from the molded body by cutting.

4, the amount of glass fiber powder added was 10 to 3.
The amount of bearing wear was tested and compared within the range of 0% by weight. Composition and bearing tests were further conducted mainly on those with a small amount of bearing wear but with an added amount of glass fiber, that is, 20% by weight, and were used as the basis for determining other compositions. In Examples 1 to 5 and Comparative Examples 18 to 22, the effect of the filler added after the glass fiber powder is revealed. First, it can be seen that the addition of iron oxide powder improves the wear resistance of the bearing. Furthermore, Cd (S, Se) powder, PbO powder, and lead chromate powder are satisfactory as sliding materials in terms of friction coefficient, amount of bearing wear, and degree of damage to the mating shaft. Furthermore, Cd (S, Se) powder and lead chromate powder do not generate any abnormal noise and are satisfactory. However, these Cd (
S, Se), PbO, and lead chromate have problems with toxicity. Therefore, in actual production activities, equipment to prevent contamination during handling is expensive, and when it is commercialized, it cannot be used in applications where consideration of toxicity is important, such as food equipment, and its usage is limited.

奏することが明らかである。In this respect, by adding iron oxide powder, the wear resistance of the bearing can be sufficiently improved and a high quality bearing can be produced. Furthermore, in Examples 6 to 8, the effect of the specific iron oxide powder in which the average particle size of the iron oxide powder was adjusted to 4 to 6 μm becomes clear. It can be seen that by adjusting the particle size to 4 to 6 μm, the surface of the mating material is quickly polished, the generation of abrasion powder is reduced, and as a result, abrasive wear is prevented. In the end, Cd (S, S), which has the problem of toxicity mentioned earlier,
e) It has become clear that the same performance as powder, PBO powder, and lead chromate powder can be obtained with safe iron oxide powder by specifying its particle size. Furthermore, from Examples 9 to 11 and Comparative Examples 23 and 24, the addition of special phenol resin powder was found to be effective in reducing the generation of abnormal noise called "squeal" during sliding, and was also found to be effective in reducing the coefficient of friction. Special phenolic resin powder (Example 10.11.13.14) and B
a5O powder (Comparative Example 23), CaF2 powder (Comparative Example 24)
), it is clear that the addition of special phenol resin powder has a great effect on preventing noise generation and lowering the coefficient of friction.
