。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.

いた。(Problems to be Solved by the Invention) 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 surface treatment Although the liquid is more effective as an aesthetic treatment agent than as an anti-blocking agent, it is not able to sufficiently suppress the adhesive force, and the surface of the elastic body may leak due to liquid components such as silicone oil, causing poor appearance. In addition, the latter chemical treatment chemicals reduce the coefficient of friction by chemically treating the surface, such as by converting diene rubber into chloride, and harden only the surface, resulting in blocking. It is intended to prevent
In order to obtain the desired appropriate 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 the residual halogen can lead to rust in composite products containing metal. It had many drawbacks.
本発明はこの様な欠点を除去し、すべり及びブロッキン
グ対策に有効な表面処理液を提供するものである。The present invention eliminates these drawbacks and provides a surface treatment liquid that is effective as a countermeasure against slippage and blocking.
本発明者は、上記従来の欠点を克服するため鋭意研究し

型品の外観を損なわないことを見い出した。As a result of intensive research to overcome the above-mentioned conventional drawbacks, the present inventors have discovered that by dispersing and mixing an aqueous ionomer dispersion into an emulsion-type silicone surface treatment liquid, the blocking effect of the elastic body can be sufficiently improved and molding can be achieved. It has been found that this method does not impair the appearance of the product.

を起こす。In addition, the particle size of the ionomer in the surface treatment liquid in the present invention is preferably a rectangular aqueous dispersion with a particle size of 0.5 μm or less, preferably 0.2 μm or less. If the particle size exceeds α5μ, the appearance of the molded product will be impaired and coating will not be uniform. Further, the concentration of the ionomer is preferably 0.1 to 5 parts by weight, preferably 0.5 to 2.0 parts by weight. If it is less than 0.1 part by weight, the anti-blocking effect of the molded product will be significantly reduced, and 5
．． If the amount exceeds 0 parts by weight, uniform application will not be possible, resulting in poor appearance.

−等による強制乾燥であっても良く特に限定はしない。In the present invention, the surface treatment liquid may be applied by any method such as dipping or spraying, and the drying method may be natural drying or forced drying by heating or air blowing. There are no limitations.

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. However, out of 100 vulcanized rubber pieces treated with a conventional surface treatment solution, blocking occurred throughout the entire area, and an average of 90 pieces had a high degree of blocking, which was difficult to remove.
