に一層増加することになる。 Vulcanized rubber exhibits high elasticity over a wide temperature range, but has drawbacks such as poor frictional properties and adhesive phenomena. Therefore, if these drawbacks can be overcome, the functions will be further improved and the usefulness of rubber molded products in product applications will be further increased.

であることを見出した。 An example of where these drawbacks are currently a problem is automobile wiper blades. Rubber molded products currently used for wiper blades have a large coefficient of dynamic friction (vertical load/tensile force), and this value is generally 1 or more. For this reason,
When using this, not only does it require a relatively large driving force, but it also has problems such as producing scraping noise and not being able to sweep a clean surface due to stick slip. In order to solve these problems, the inventors of the present invention have conducted extensive research and found that it is effective to form a specific mixture film on the surface of a rubber molded article by high-frequency sputtering.

The mixture coating is formed on the sliding surfaces and, in the case of other rubber molded products, on their sealing surfaces.

３〜50重量％の割合で用いられる。 Tetrafluoroethylene resin is generally used as the fluororesin that is one of the components used to form the mixture film. Further, as the other component, at least one of copper, zinc, carbon, glass, molybdenum disulfide, or boron nitride is used.
These other components are components for improving abrasion resistance, and when used together with fluororesin in applications that require both sliding properties and abrasion resistance, the fluororesin alone has insufficient abrasion resistance. improve.
In order to exhibit such an improvement effect, these components are used in a proportion of about 1 to 70% by weight, preferably about 3 to 50% by weight of the mixed components.
高周波スパツタリング法による混合物被膜の形

する。なお、符号１０は、圧力計である。 In the sputtering process, the air inside the reactor is first evacuated from the exhaust port 6 using a vacuum pump such as an oil diffusion pump (not shown) to reduce the pressure to the order of 10 -5 Torr, and then the air inside the reactor is evacuated to the order of 10 -5 Torr.
While adjusting the pressure, open the pressure adjustment valve 8, introduce argon gas etc. from the cylinder 9 of inert gas such as argon into the reactor, and increase the pressure there by 5x.
10 -3 Torr. Here, adjust the main valve (not shown) of the exhaust stack to set the pressure to 5×10 −2 Torr. In addition, the code|symbol 10 is a pressure gauge.

This is carried out by taking out the rubber molded article on which the mixture film has been formed from inside the reactor.

される。 The mixture film formed on part or all of the surface of the rubber molded product in this way was used as a target for high-frequency sputtering, even though it was a fluororesin with other components non-uniformly dispersed. Since each component of the mixture is uniformly mixed on a molecular order to form a coating, the coating itself has flexibility, low frictional resistance, and excellent wear resistance. Therefore, in a rubber molded article on which such a mixture film is formed, all of the above-mentioned drawbacks are effectively improved. Moreover, the film formed by high-frequency sputtering has a high particle collision energy of approximately 10 to 100 eV during film formation, and has a high adhesion strength to the rubber molded product substrate.
The coating life is long, and therefore the above effects are effectively maintained.

ることが確認された。 From the above results, the frictional resistance of the mixture coated according to the present invention is significantly reduced compared to the one not treated with high-frequency sputtering, and compared to the one coated with a single fluororesin. In fact, even when comparing the sliding parts after the friction and wear test, wear marks were seen on the sliding surfaces in the case of the single fluororesin coating, but in the case of the mixture coating. In this case, it was confirmed that there was no wear and that it was wear resistant.
