に詳しくは、加硫フッ素ゴム成形品の低摩擦化ならびに
非粘着化を達成させるための表面処理方法に関する。TECHNICAL FIELD The present invention relates to a surface treatment method for a vulcanized rubber molded article. More specifically, it relates to a surface treatment method for achieving low friction and detackification of a vulcanized fluororubber molded article.

非粘着化の要請が、近年とみに高まっている。[Prior Art] and [Problems to be Solved by the Invention] Vulcanized rubber generally has large frictional resistance or may have tackiness, so that other preferable properties of the vulcanized rubber base material are sufficiently utilized. However, there are restrictions on the intended use. For this reason, demands for low friction and non-adhesion of the surface of vulcanized rubber molded products have been increasing in recent years.

題となり易いなどの課題を抱えている。Conventional techniques for reducing the friction and detackifying the surface of the vulcanized rubber molded product include a method of curing the vulcanized rubber surface with a chemical and a method of coating with a resin dispersion of polytetrafluoroethylene. However, the former method has the drawback that the chemical structure of the cured part changes significantly, and as a result the rubber-like elasticity, which is the most characteristic feature of rubber, is significantly lost, and the latter method involves spray coating, brush coating, etc. In addition to the above process, there is a problem that the bondability with the base material is likely to become a problem.

用いられる。Although these polyfunctional unsaturated compounds can be used as they are if they are liquids, they are preferably used as a soluble solvent solution. As a solvent for that,
Although a material which does not dissolve the vulcanized fluororubber molded article is used, it is desirable that the vulcanized fluororubber molded article swells to some extent so as to penetrate the surface of the molded article by about several tens of μm. In practice, acetone, methyl ethyl ketone, methanol, ethanol, toluene, tetrahydrofuran, etc. are used so as to form a solution concentration according to the degree of treatment.

る。The surface treatment is considered to be due to the co-crosslinking of the polyfunctional unsaturated compound radical and the polymer radical. Therefore, the organic peroxide is dissolved in the polyfunctional unsaturated compound (solution) and the inert gas atmosphere is set. Among them, the polyfunctional unsaturated compound-adhered vulcanized fluororubber molded article is heated to a temperature at which organic peroxide decomposes to generate radicals.

グ膜とは異なり、剥離や亀裂などを生じさせない。[Function] and [Effects of the Invention] By using a polyfunctional unsaturated compound and surface-treating it with an organic peroxide radical, the surface layer portion of the vulcanized fluororubber molded product is further cross-linked in the order of several μm to several hundred μm. It is considered that a high cross-linking density results and locally hardened parts are formed. As a result, the surface of the vulcanized fluororubber molded article is reduced in friction and detackified without substantially reducing the inherent elasticity of the fluororubber molded article as a whole. In addition, since the composition of the cured part is essentially close to the original rubber composition and is integrally formed, unlike a simple coating film, peeling or cracking does not occur.
