〔産業上の利用分野〕
本発明は、加硫ゴム成形品の表面処理方法に関する。更
に詳しくは、加硫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。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for surface treatment of vulcanized rubber molded articles. More specifically, the present invention relates to a surface treatment method for achieving low friction and non-adhesion of vulcanized rubber molded articles.
〔従来の技術〕および〔発明が解決しようとする課題〕
加硫ゴムは、一般に摩擦抵抗が大きくまた粘着性を有す

性質が十分に生がされず、使用用途に制限がみられる。[Prior art] and [Problem to be solved by the invention]
Vulcanized rubber generally has a high frictional resistance and may be sticky, so that other desirable properties of the vulcanized rubber base material are not fully utilized, and the applications of the vulcanized rubber are limited.
このため、加硫ゴム成形品表面の低摩擦化ならびに非粘
着化の要請が、近年とみに高まっている。For this reason, there has been an increasing demand for low friction and non-adhesive surfaces of vulcanized rubber molded products in recent years.
加硫ゴム成形品表面の低摩擦化ならびに非粘着化のため

題となり易いなどの課題を抱えている。Conventional techniques for reducing friction and non-adhesion on the surface of vulcanized rubber molded products include a method of curing the vulcanized rubber surface with chemicals, and a method of coating it with a polytetrafluoroethylene resin dispersion. However, the former method has the disadvantage that the chemical structure of the cured part changes significantly, resulting in a significant loss of rubber-like elasticity, which is the most important characteristic of rubber. In addition to requiring the following steps, there are other problems such as bondability with the base material.
本発明は、成形品全体の弾性などゴム本来の特性を実質
的に低下させることなく、加硫ゴム成形品表面の低摩擦
化ならびに非粘着化を達成させることを目的としている
。The object of the present invention is to achieve low friction and non-adhesion on the surface of a vulcanized rubber molded product without substantially reducing the inherent properties of rubber such as the elasticity of the entire molded product.

機過酸化物分解温度に加熱する方法により達成される。The object of the present invention is achieved by a method of heating an organic peroxide crosslinked vulcanized rubber molded article having a dialkyl type organic peroxide adhered to one surface thereof to the decomposition temperature of the organic peroxide.

ゴムあるいは合成ゴム、例えばスチレン・ブタジェンゴ
ム、シリコーンゴム、ニトリルゴム。The organic peroxide vulcanized rubber molded product to be surface-treated is natural rubber or synthetic rubber, such as styrene-butadiene rubber, silicone rubber, and nitrile rubber.

ム（ＥＰＤＭ）などを架橋可能な任意の有機過酸化物で
架橋させた加硫成形品である。It is a vulcanized molded product made by crosslinking hydrogenated nitrile rubber, ethylene-propylene copolymer rubber (EPDM), etc. with any crosslinkable organic peroxide.

Dicumyl peroxide, α,α'-bis(tert-butylperoxy-m-isopropyl)benzene, 2,5-dimethyl-2,5-di(tert-butylperoxy)hexane, 2,5-dimethyl- 2,5-di(tert-butylperoxy)hexyne-3 and the like are used.

応じた溶液濃度を形成するようにして用いられる。These dialkyl type organic peroxides can be used as they are if they are in liquid form, but they are preferably used as a solution in a soluble solvent with a concentration of about 1% or more. The solvent used for this purpose is one that does not dissolve the vulcanized rubber molded product, but it is desirable to use a solvent that swells the vulcanized rubber molded product to some extent so as to penetrate the surface of the molded product by several tens of micrometers. Actually, acetone, 2-butanone,
Methanol, ethanol, toluene, etc. are used to form a solution concentration depending on the degree of treatment.

of organic peroxide or its organic solvent solution at a temperature of about 1
After soaking for ~60 minutes and removing the solvent by air drying or preheating when used in solution, the organic peroxide-coated vulcanized rubber molded article is rapidly heated. The heating time varies depending on the type of rubber of the vulcanized product to be surface treated and the decomposition temperature of the organic peroxide used.
It is carried out at 00 to 300°C for about 1 minute to 24 hours, preferably at about 150 to 250°C for about 10 minutes to 2 hours.

ることもできる。Active radicals are generated by the decomposition of organic peroxides by heating, but if oxygen is present in the atmosphere, the radicals disappear by recombination, so treatment under an inert atmosphere is required. By controlling the amount of organic peroxide used, surface treatment can also be performed in the presence of oxygen. In addition, in the surface treatment liquid, radicals are generated by organic peroxide radicals such as triallyl isocyanurate, triallyl cyanurate, N,N'-m-phenylene bismaleimide, diallyl phthalate, etc., and are co-produced with polymer radicals. A crosslinking polyfunctional unsaturated compound can also be present.

られる。[Action] and [Effects of the Invention] By heating and surface-treating the dialkyl type organic peroxide, the surface layer of a vulcanized rubber molded product can be reduced from several μm to several μm.
It is believed that the kneading density is several 100, and that hardened portions are formed locally.
これにより、加硫ゴム成形品表面の低摩擦化ならびに非
粘着化が，成形品全体のゴム本来の弾性などを実質的に
低下させることなく達成される。As a result, low friction and non-adhesion of the surface of the vulcanized rubber molded product can be achieved without substantially reducing the inherent elasticity of the rubber of the entire molded product.
また、硬化部分は、その組成が本質的に元のゴム組成に

ング膜とは異なり，剥離や亀裂などを生じさせない。Furthermore, since the cured portion has a composition essentially close to the original rubber composition and is formed integrally, unlike a mere coating film, it does not cause peeling or cracking.
