【発明の詳細な説明】
〔産業上の利用分野〕
本発明はゴム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 rubber 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ゴム
弾性体で形成された成型物は、重ね合せたり包装すると
互いに粘着して接合し合うブロッキングを起すため作業
上程々の問題を起していた。Conventionally, molded products made of rubber elastic bodies, such as bearing seals or oil seals, have caused problems when stacked or packaged because they adhere to each other and cause blocking.
このため粘着防止の後処理が必要となり、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。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.
しかし、前者の表面処理液を塗布する方法の有機溶剤に

た高価で６す、ｔたノ・ロゲンの残存により金属を含む
複合製品では錆の発生につながるなど多くの欠点を有し
ていた。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 it is effective as an agent, it not only cannot sufficiently suppress the adhesive force, but also has 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 rubber, to lower the coefficient of friction and harden only the surface to prevent blocking.
In order to obtain the desired appropriate surface roughness and surface hardening, there remain very difficult problems in adjusting the chemical blending ratio and treatment time, and it is also expensive6. It had many drawbacks, including the fact that it led to outbreaks.
（問題点を解決するための手段〕
本発明はこの様な欠点を除去し、すべり及びブロッキン
グ対策に有効ですべり性のよい表面処理液を提供するも
のである。(Means for Solving the Problems) The present invention eliminates these drawbacks and provides a surface treatment liquid that is effective as a countermeasure against slipping and blocking and has good slipping properties.
本発明における表面処理液は、融点４５〜５０℃の低分

たは乳化せしめて得られる表面処理液である。The surface treatment liquid in the present invention is a solvent or dispersion of 0.1 to 10 weight percent of a low molecular weight vinyl polymer with a melting point of 45 to 50°C and 0.1 to 10 weight percent of dimethylsiloxane silicone oil of 10 to 1000 as. Alternatively, it is a surface treatment liquid obtained by emulsification.

好である。In general, polymer waxes such as polyethylene wax have a hard film and are advantageous for blocking, but their fluidity is poor even at temperatures above their softening point, making it extremely difficult to form a uniform film on the surface of vulcanized rubber. This is disadvantageous from an aesthetic point of view. On the other hand, hedral baraffin wax has high fluidity at temperatures above its melting point, which is advantageous for forming a uniform film on the vulcanized rubber surface, but the film is soft and disadvantageous against blocking. 0 However, the above-mentioned low molecular weight vinyl polymer has the same fluidity as solid paraffin at temperatures above its melting point, and can easily form a uniform film, and the film itself has a lower flow rate than solid paraffin. It is very hard, very advantageous against blocking, and good from an aesthetic point of view.
この様に低分子量ビニル系重合体を使用することにより
、ポリエチレンワックスなどの重合体、固形パラフィン
両者のもつ欠点を解消し、利点を兼ね備えたものとなる
。By using a low molecular weight vinyl polymer in this way, the disadvantages of both polymers such as polyethylene wax and solid paraffin can be overcome, and the advantages can be combined.

The dust prevention effect also increases.

表面処理液である。As explained above, the present invention is a surface treatment liquid that uniformly forms a hard coating, which is advantageous for blocking resistance, on the interface of stacked vulcanized rubber and provides satisfactory blocking resistance and slipping properties.

A surface treatment solution was prepared by adding a portion of the solution and dispersing it with a disperser.

おり、すべり特性にもすぐれていた。Prepare 1,000 pieces of 10 types of vulcanized rubber pieces of different sizes, dip them in the surface treatment liquid obtained by mixing them in the proportions above, and dry and harden them at 70°C for 5 minutes. Ta. In addition to stacking 100 pieces of this, 1000 pieces of vulcanized rubber without surface treatment liquid were also stacked.
Prepare 100 sheets, stack them in the same way, and heat them at 40°C.
After being left in the atmosphere for 7 days, the blocking state was observed. As a result of observation, no blocking was observed in the vulcanized rubber pieces treated with the surface treatment liquid of the present invention, and they remained in good condition and had excellent sliding properties.
しかし表面処理液を施こさない加硫ゴム片は１００枚中
はぼ全体にブロッキングを起し平均５３枚がブロッキン
グ度が大きく、なかなかとれない状態であった。However, out of 100 pieces of vulcanized rubber that were not treated with the surface treatment solution, blocking occurred throughout the pieces, and an average of 53 pieces had a high degree of blocking, which was difficult to remove.
この様に本発明による表面処理液はこれをゴム表面に塗

This provides an ideal surface treatment solution that also contributes to improvements in surface treatment.
