して用いられるフッ素ゴム成形品の製造方法に関する。Description: TECHNICAL FIELD The present invention relates to a method for producing a fluororubber molded product used as a sealing member such as a packing or a gasket.
発明の技術的背景およびその問題点 フッ素ゴム成形品は、耐熱性、耐薬品性、耐油性など
に優れているため、パッキン、ガスケットなどの流体シ
ール用部材として広く利用されている。TECHNICAL BACKGROUND OF THE INVENTION AND PROBLEMS OF THE INVENTION Fluororubber molded articles are widely used as fluid sealing members such as packings and gaskets because of their excellent heat resistance, chemical resistance and oil resistance.
ところが、このようなフッ素ゴム成形品を摺動部での
シール用部材として用いた場合、摩擦係数が充分には小
さくなく、さらに摩擦係数が小さいフッ素ゴム成形品の
出現が望まれていた。However, when such a fluororubber product is used as a sealing member in a sliding portion, the appearance of a fluororubber product whose friction coefficient is not sufficiently small and whose friction coefficient is small has been desired.
そこでフッ素ゴムに加硫剤および充填剤とともにフッ

数が小さくなるが、現状ではこのフッ素樹脂粉末の充填
量に制限があるため、未だ摩擦係数が充分に小さなフッ
素ゴム成形品が得られていない。Therefore, by blending a powder of solid lubricant such as fluororesin with a vulcanizing agent and a filler together with a fluororubber to prepare a fluororubber compound, and then vulcanizing the compound to produce a molded product, A method for reducing the coefficient of friction of the fluororubber molded article has been proposed. According to this method, the obtained fluororubber molded article has a smaller friction coefficient as the amount of the fluororesin powder added to the fluororubber compound increases, but at present, there is a limit to the filling amount of the fluororesin powder. For this reason, a fluororubber molded product having a sufficiently low coefficient of friction has not yet been obtained.

直角の方向に避けやすいなどの問題点があった。That is, when using a fluororubber compound in which 30 parts by weight or more of fluororesin powder is mixed with respect to 100 parts by weight of fluororubber, the viscosity becomes too high at the time of kneading, and it becomes difficult to knead. The fibers are agglomerated or agglomerate, and the kneaded composition forms a layer in the grain direction and causes poor rubber dispersion. For this reason, the mechanical strength of the obtained molded article is remarkably reduced, and there is a problem that, for example, it is easy to avoid in a direction perpendicular to the grain.
