Description of the Related Art PTFE moldings are not only excellent in heat resistance and chemical resistance, but also have a small coefficient of friction and have self-lubricating properties, so that they are used as sliding members for piston rings, bearing seal rings, chip seals, etc. Widely used.

There has been proposed a method of improving wear resistance by adding a filler such as glass beads or bronze powder and molding.

発明を完成するに至った。As a result of earnest research for solving the above problems of the prior art, the present inventor has found that PTFE
A specific third component is further added to the system in which carbon fiber is added as a filler to the composition having these specific ratios,
It was found that a molded product having excellent wear resistance, a small friction coefficient and an appropriate elastic modulus can be obtained, and the present invention has been completed.

The present invention relates to a fluororesin composition characterized in that it is 10% and the volume sum of carbon fiber and solid lubricant is 15% or less of the volume of the molded product.

固体潤滑剤が１〜１０％である。The composition according to the present invention contains PTFE, carbon fiber and a solid lubricant as essential components. And, the weight ratio of each component in the total weight of these three is 75 to 98% for PTFE, 1 to 15% for carbon fiber,
Solid lubricant is 1 to 10%.

外のものを使用することもできる。The carbon fiber mainly contributes to the wear resistance of the molded product, and if the content is too small, the effect of improving the wear resistance cannot be obtained, and if it is too large, the mutual binding of PTFE in the molded product is hindered. As a result, the strength and elongation of the molded product decrease, and the elastic modulus increases and the sealing property deteriorates.
This carbon fiber has a diameter of about 5 to 20 μm and a length of about 5 to
It is preferable to use what is generally called "milled fiber" having a thickness of 300 µm, but it is also possible to use materials other than milled fiber.

ある。The solid lubricant is added in order to suppress the tendency of the friction coefficient to increase due to the addition of carbon fiber. Therefore, if this blending amount is too small, the effect of suppressing the increase in the friction coefficient becomes insufficient. On the other hand, even if the solid lubricant is blended in a large amount in excess of the above-mentioned predetermined amount, the effect of suppressing the friction coefficient will not be further exerted. A mixture of boron nitride and molybdenum disulfide is used as the solid lubricant. The mixing ratio of these two is not particularly limited, but it is preferable that the ratio of boron nitride in the total weight of the two is 30 to 95%.

より体積和の異なる組成物を得ることができる。Further, in the present invention, the volume sum of the carbon fiber and the solid lubricant must be 15% or less of the volume sum of PTFE, the carbon fiber and the solid lubricant.
If the total volume of the carbon fiber and the solid lubricant is larger than this, the strength and elongation of the molded product obtained from this composition will decrease, and the abrasion resistance will also decrease. The ratio of the volume sum of the carbon fiber and the solid lubricant in the volume of the three can vary mainly depending on the particle diameter of these particles. That is, even if PTFE, carbon fiber and the solid lubricant are mixed in the same weight ratio, if the particle diameters of these are changed, the volume sum of the carbon fiber and the solid lubricant in the volume of the three changes. Therefore, even when these three components are mixed in the same weight ratio, it is possible to obtain compositions having different volume sums by appropriately changing the particle diameters thereof.

る。The molded article according to the present invention can be obtained by the same method as the conventionally known PTFE molding method. For example, PTFE, carbon fiber and solid lubricant are uniformly mixed, and this mixture is filled in a mold to about 200-10.
It can be manufactured by a method of press-molding under a condition of 00 kg / cm 2 , taking out from the mold, heating the pre-molded product at a temperature of the melting point of PTFE or higher and firing it. Of course, the molded product obtained by this method can be further processed into a desired shape. For example, a rod-shaped or cylindrical molded product can be obtained by the above method, and then this can be cut into a flat plate, a ring, a spiral, or the like.

The characteristic value is not more than dyn / cm 2 .

It has been found that when the mating material is made of a soft metal such as aluminum, brass or copper, the smaller the elastic modulus of the sliding material is, the more excellent the adhesion and the sealing property with the mating material. And
It was confirmed that the molded product having the above elastic modulus has sufficient practicality.
