[0036]

[0037] To a mixture of polydimethylsiloxane having a vinyl group and a hydrogenated diene silane compound, a platinum-based catalyst is added to carry out an addition reaction, and the addition reaction-type hardened silicone resin (Shin-Etsu Chemical Co., Ltd.) manufactured, KS-847H) were dissolved in various organic solvents shown in the following Table 1 to prepare silicone resin coatings with a total solid content concentration of 3.0% as release coat coatings. The compounding quantity of each material is as follows.

[0038] Hardening silicone resin KS-847H 300g

[0039] (Manufactured by Shin-Etsu Chemical Co., Ltd., 90 g of resin with a solid content concentration of 30%)

[0040] Platinum catalyst CAT-PL-50T (manufactured by Shin-Etsu Chemical Co., Ltd.) 3.0 g

[0041] Organic solvent 2700g

[0042] Using a bar applicator, the obtained silicone resin coating was coated on a 38 μm thick biaxially stretched polyethylene terephthalate (PET) film as a base mat...

Abstract

A stripping membrane for preparing the ceramic substrate of printed circuit by coating ceramic paint on it and then stripping the ceramic paint layer from it, and its preparing process are disclosed. The obtained ceramic substrate has high size and shape precision. Said stripping membrane is prepared through coating it on at least one surface of basic membrane in such manner that there are two non-coated ends on said basic membrane and coating the oily ink on said stripping membrane and said non-coated ends.

Description

technical field [0001] The present invention relates to a release film and a method for producing the same, and more particularly to a release film for producing a laminated ceramic capacitor and a method for producing the same. technical background [0002] When manufacturing ceramic electronic components such as capacitors, piezoelectric components, positive thermistors, negative thermistors, or varistors, for example, ceramic coatings containing ceramic powder, organic binders, plasticizers, solvents, etc., are used It is coated on a flexible support by the doctor blade method to form a printed circuit board (dielectric layer), on which electrodes such as palladium, silver, and nickel are formed by screen printing. In the manufacturing process, when a laminated structure is obtained, the obtained printed circuit boards are laminated to form a desired laminated structure, and a ceramic printed circuit board is obtained through a punching and cutting process. The binder in...
