Abstract
Description
【発明の詳細な説明】 産業上の利用分野 絶縁性樹脂膜材。[Detailed description of the invention] Industrial applications Insulating resin film material.
従来の技術
絶縁性樹脂膜材としては従来から種々のものが知られて

い製品が得られない。Problems to be Solved by the Invention However, the thickness of the film material made of silicone rubber as described above cannot be made sufficiently small, for example, 200 μm.
There is a limit to how thin the layer is, and it is impossible to obtain a thinner layer than this, so there are restrictions on its use. In addition, the tensile strength is significantly reduced by thinning the layer, and from this point as well, a desirable product cannot be obtained.
「発明の構成」

とができる。EXAMPLE To explain the specific embodiment of the casing according to the present invention as shown in the attached drawings, an example of a porous membrane material stretched with polytetrafluoroethylene resin is shown in an enlarged scale in FIG. Countless fibers 11 between fine nodules 12
Although it is formed in a spider web shape, in the present invention, silicone rubber is made to resist seeping into such a stretched porous membrane material 1, and its cross-sectional structure is shown in FIG. When further enlarged, it is shown in Fig. 2, and the silicone rubber layer 2 is filled in the structure of the fibers 11 described above, and those that adhere excessively to the front and back are scraped off as much as possible, but the surface is smoothed. Therefore, it may be covered with an extremely thin silicone rubber layer 2&, whose thickness is generally 50 μm.
m or less, particularly around 20 μm,
As a product, a plurality of sheets can be appropriately polymerized to have a weight of about 2W.

としてよい。In order to obtain the product of the present invention as described above, the stretched porous membrane material 1 as described above is spread on a smooth plane or a curved surface, and a crosslinking agent, a catalyst, etc. are applied as appropriate on the porous membrane material 1. Add an appropriate amount of silicone rubber solution contained in the silicone rubber solution, spread it with rubber grade, etc., and spread it while impregnating the entire surface. That is, the above-mentioned porous membrane material 1 itself is in an opaque state such as white, but when this material is sufficiently impregnated with the silicone rubber solution as described above, the entire material becomes transparent. The excess silicone rubber existing on the surface of the object is scraped off with the rubber grade to form an impregnated body.It goes without saying that such an impregnation treatment requires only one porous membrane piece 1, but in some cases two or more pieces may be used. It can be carried out in a polymerized and expanded state. In any case, the impregnated material as described above is placed in a constant temperature bath together with the flat or curved surface forming member (gold plate, etc.) and cross-linked and polymerized at about 150 to 200"C to produce a "C" product. In addition, the impregnated silicone rubber before crosslinking is made thin with a hot roll, and at the same time, a part or the whole is crosslinked and polymerized, and then completely crosslinked and polymerized in a constant temperature bath to obtain a product. Of course, in order to eliminate stickiness on the surface, a roll with a satin-like pattern may be placed behind the hot roll, or the hot roll itself may be a roll with a satin-like pattern.

Generally, the ratio is about 100 to 250%, and the strength can be effectively increased even though it has desirable flexibility and elasticity.

。６−ら工業的ｔこその効果の大きい発明でおる。"Effects of the Invention" According to the present invention as explained above, an insulating resin film copper product can be produced which has the same desirable properties as silicone rubber in terms of flexibility and elasticity, but which has sufficiently improved tensile strength. Since it is manufactured as a thin layer material with a thickness of less than 1/10 of the original material, it is useful as an insulating film material, and is also preferred in fields such as the electronic industry where conventional products have many problems in use. When used for plating masking related to 4#ζ IC, it has advantages such as excellent chemical resistance and insulation properties, and easy peeling. 6-It is the industrial t that is the most effective invention.
