〔産業上の利用分野〕
本発明は弾性体を積重ねた場合などに生じる粘着を防止
するための後処理表面処理方法に関しさらに具体的には
表面処理液に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a post-treatment surface treatment method for preventing adhesion that occurs when elastic bodies are stacked, and more specifically to a surface treatment liquid.
従来、ベアリングシールあるいはオイルシール等の弾性
体で形成された成型物は、重ね合せたり包装すると互い

要となり、その対策として表面処理液を塗布したり薬品
によって表面を化学的に変化させたりして対処していた
。Conventionally, molded products made of elastic materials, such as bearing seals or oil seals, have caused problems when stacked or packaged because they adhere to each other and cause blocking. For this reason, post-treatment to prevent adhesion is required, and countermeasures have been taken by applying a surface treatment liquid or chemically changing the surface with chemicals.

。However, in the former method of applying a surface treatment liquid, the surface treatment liquid obtained by dissolving silicone oil and a surfactant in an organic solvent, or the emulsion-type silicone oil-based surface treatment liquid, is used more as an aesthetic treatment than as an anti-blocking agent. Although they are effective as agents, they not only cannot sufficiently suppress the adhesive force, but also have the disadvantage that the surface of the elastic body leaks due to liquid components such as silicone oil, causing poor appearance. The latter type of chemical treatment chemically treats the surface, such as by halogenating the diene thread rubber, to lower the friction coefficient and harden only the surface to prevent blocking. In order to obtain the desired surface roughness and surface hardening, there remain very difficult problems in adjusting the chemical blend ratio and processing time, and it is also expensive, and there are many drawbacks such as the residual halogen that can lead to rust in composite products containing metal. It had

性をもっているので表面への吸着性にすぐれている。The composition of this surface treatment liquid is a mixture of 1.0 to 5-Oli i parts of n-paraffin wax emulsion and 0.5 to 2.0 parts by weight of silicone emulsion, and further alkyl sulfate. Add and dissolve 0.5 to 5.0 parts by weight (preferably 1.5 to 3.0 parts by weight to exhibit optimal blocking resistance) of a salt-based anionic surfactant. At that time, it may be slightly heated. [Operation] The surfactant is solid at room temperature and has a slippery property, but does not have a clear melting point like n-paraffin waxes. , no change in the state of the substance is observed even at high temperatures. Therefore, it exhibits lubricity even at high temperatures, and satisfactorily anti-blocking properties can be obtained. In addition, for vulcanized rubber having polar groups, this surfactant is suitable for sulfate groups (-3O3
M and M are metal salts) and have hydrophilicity, that is, strong polarity, so they have excellent adsorption to surfaces.

で存在しており、この界面活性剤の添加によりこの乳化
状態がさらに安定となり、処理液の管理が容易となる。Furthermore, since the concentration used in this treatment liquid is at least the Sissel limit concentration of the surfactant, it is sufficient to lower the surface tension of the emulsion. Therefore, the contact angle on the surface of the vulcanized comb becomes small, and it spreads easily over the rubber surface, making it easy to apply by dipping. In addition, the n-paraffin and silicone emulsions used in this treatment liquid are oil-in-water type (0/W type) in which oil particles are dispersed in water.
The addition of this surfactant makes this emulsified state more stable, making it easier to manage the processing solution.
さらにこの種の界面活性剤は生物分解が容易である。Furthermore, this type of surfactant is easily biodegradable.
該表面処理液の使用に際しては、この表面処理液中に加
硫ゴムを浸漬した後７０℃〜１５０℃で数分から士数分
乾燥させる。When using the surface treatment liquid, the vulcanized rubber is immersed in the surface treatment liquid and then dried at 70°C to 150°C for several minutes to several minutes.
乾燥後の加硫ゴム表面にはシリコン被膜上にｎ−パラフ

十分な耐ブロッキング性を有することができる。On the surface of the vulcanized rubber after drying, n-paraffin wax and solid surfactant are scattered on the silicone film. Therefore, as described above, it can have sufficient blocking resistance even at high temperatures.

Blocking did not occur in any of the vulcanized rubber pieces that had been treated with the surface treatment liquid, and blocking was observed in almost all of the untreated vulcanized rubber pieces, with blocking being particularly noticeable in half of the blocks.
