ラ、あるいは、すじが発生しやすい。 Silicone-coated plastic film has superior surface smoothness, dimensional stability, heat resistance, transparency, and flatness compared to paper, which is the conventional base material.
Because of its high tensile strength, it has a wide range of uses, including not only as a substitute for release paper, but also for tightening the grips of fishing rods and golf shafts.
However, it is not easy to uniformly apply the silicone resin to the surface of the plastic film because of the insufficient wettability of the silicone resin to the plastic film and the static electricity charged on the plastic film. For example, when looking at the surface wetting properties of plastic films, which indicate how easily paints and inks get on them, polyester has a wettability of 38 to 45 dyne/cm, and polyolefin has a wettability of 38 to 45 dyne/cm.
32dyne/cm, 39-45dyne/cm for PVC (all according to JISK-6768), etc. On the other hand, the wetting properties of silicone resin vary depending on the type, but are 18 to 25 dyne/cm. Furthermore, the static electricity of the film itself and the distribution of frictional charges during processing are not uniform, and this static electricity tends to cause repelling phenomena, coating unevenness, or streaks.

果が得られなかつた。 These non-uniformities in the thickness of the silicone coating cause variations in peel resistance when it is used as a release paper. In order to solve this problem, various measures have been taken, such as selecting a silicone resin, devising the diluting solvent used, and removing static electricity from not only the film but also important parts of the coating equipment, but none of them have been able to achieve a satisfactory effect.

が判つた。 Another method was to use a film pre-contained with a non-metallic antistatic agent, but this method had poor adhesion between the film and the silicone, and the silicone was not applied after drying and curing. A smear that becomes cloudy when you rub the surface with your finger,
This causes rub-off, where the silicone coating falls off.
Furthermore, it has been found that some combinations of silicone resin and antistatic agent have defects that cause curing inhibition.

経時変化によつて劣化する欠点がある。 Another possibility is to apply an antistatic agent to the surface that is not coated with silicone, but this may cause the antistatic agent to migrate and impair the coating properties of the silicone.
It has the disadvantage that it reduces the inherent properties of silicone or deteriorates over time.

チツクフイルムに関するものである。 The present invention improves the adhesion between the silicone resin and the film by providing a conductive layer such as a metal thin film layer on the surface of the film, dissipating static electricity generated on the surface or inside the plastic film, and eliminating local charging. This invention relates to a silicone-coated plastic film in which a silicone resin is coated uniformly and beautifully on the film.

In addition, even if coating processing is performed at high speed, these drawbacks are small.

Alternatively, a conductive layer 3 made of a resin layer containing these powders is provided so that the surface resistance is 10 13 Ω or less, preferably 10 8 Ω or less, or a conductive layer 3 is provided on one side of the plastic film 2 as shown in FIG. As in the case of FIG. 1, a conductive layer 3 such as a metal thin film is provided, and a silicone resin layer is provided on the surface of the conductive layer.

Further, this film may contain a plasticizer, a coloring agent, a slip improver, etc., as necessary, to the extent that it does not interfere with conductive layer processing such as vapor deposition and silicone resin processing.

縁計を用いて20゜Ｃ、65％RHの条件で行なう。 Various methods such as vacuum evaporation, sputtering, and ion plating are used to provide these conductive layers. Furthermore, a blend of these powders in a resin may be applied. The thickness of the conductive layer formed by metal vapor deposition varies depending on the material, but is usually about 0.01 to 0.2 microns.
If transparency is required, in a region with a thickness of several tenths of the above lower limit or more, the surface resistance should be 10 13 in relation to the required electrostatic properties.
An appropriate thickness of Ω or less, preferably 10 8 Ω or less, is determined based on the relationship with the specific resistance of the material.
In addition, if a metallic luster is required for the appearance, use a material with a metallic luster and a thicker material; conversely, if a translucent material is required, or if transparency is required, a thinner material is used. , use something that has transparent properties. That is, the conductive layer to be used may be selected based on the electrical properties and optical properties specific to the material.
When coating with a resin containing metal powder or carbon particles, the thickness is usually 1 to 2 microns.
Note that the surface resistance is measured using, for example, a super megohmmeter manufactured by Yokogawa Electric under conditions of 20°C and 65% RH.

In reality, solvent types are often used due to productivity, economy, performance, etc. A coloring agent, an antifoaming agent, a dispersing agent, etc. may be added to the silicone resin. In addition, the coating amount of the silicone resin layer varies depending on the application, but the silicone resin solid content is 0.005
A range of ~5 g/ m2 is preferred.

It goes without saying that it has extremely good performance in other uses, and is also effective as a separator for general adhesives. In particular, when used as a release paper during the production of multilayer capacitors made from ceramic sheets, there is no peeling charge during release and no dust is trapped. It has the same effect when used as a release paper when manufacturing plywood, etc.
