At this time, since the tetrafluoroethylene resin has high heat resistance, chemical resistance, and electrical resistance, the heat resistance, chemical resistance, and high electrical resistance of the polyphenylene sulfide resin are not impaired.

As shown in the figure, tetrafluoroethylene resin has a II4 structure in which the skeleton of a chain of carbon atoms is surrounded by large fluorine atoms without any gaps, and the surface of the molecule is smooth and the surface friction The coefficient is very small, so the addition of tetrafluoroethylene l1411ti lowers the friction coefficient of polyphenylene sulfide resin, and furthermore, the reduction in friction coefficient improves the wear characteristics.

In addition, 0.1 to 1 of tetrafluoroethylene resin
Since 00 μm fine powder is added, the tree WBl! The product has a structure in which fine particles of tetrafluoroethylene resin are scattered,
It can also be used for parts with complex and minute shapes and parts that require high precision. Therefore, not only under normal usage conditions, but also in fields that require special conditions such as heat resistance, chemical resistance, high electrical resistance, and high precision, we need sliding parts materials with excellent friction and wear characteristics. can be provided.

ので、５０％（重量比）以下の添加量が好ましい。As the tetrafluoroethylene resin fine powder used in the resin composition of the present invention, for example, the product name "Sunflon SG #10
There are pulverized products of each grade commercially available as #00 and #3000J, and each grade can be selected and used depending on the size, shape, action (load, etc.) of the parts to be used. At this time, if the amount of tetrafluoroethylene resin (II) added exceeds 50%, the properties of the polyphenylene sulfide resin will be adversely affected, so the amount added is preferably 50% (weight ratio) or less.

有する。In addition, the above-mentioned "Sunflon" undergoes a so-called calcination treatment in which the resin is held at a temperature of around 380°C for a certain period of time before pulverizing the tiilJ fat. Since the ethylene resin powder has good dispersibility when heated with the polyphenylene sulfide resin powder, it is effective when the tetrafluoroethylene resin particles are uniformly distributed in the resin composition.

できる。Incidentally, glass fiber can be appropriately added to the resin composition of the present invention for the purpose of improving properties such as impact strength. Normal for polyphenylene sulfide resin! Glass fiber is often added for the purpose of improving properties such as li impact strength, but when doing so, there is a problem that friction properties and wear properties deteriorate. In other words, when glass fiber is added, the point 1' in the sliding part with other objects is
Gelasfu and var are exposed on the surface of phenylene sulfide 1D4 fat, which deteriorates the friction and wear characteristics. On the other hand, when glass fiber is added to the resin composition of the present invention, there is no such problem because the surface exposure of the glass fiber can be suppressed by the tetrafluoroethylene resin. While having excellent mechanical properties such as excellent high impact strength, it can exhibit excellent friction and wear properties.
