example 1

[0134] Working Example 1 - Composition 1

[0135] (A) 30.0 parts of polydimethylsiloxane (plasticity: 1.15; hexenyl group vinyl (CH2=CH-) part content) having hexenyl groups at both terminals and on the side chain : 0.80 mass %), (B) 1.5 parts of dimethylsiloxane (plasticity: 1.20; vinyl group content: 0.02 mass %), (C) 1.3 parts of 25 mPa Dimethylmethylhydrogenpolysiloxane of s viscosity (such that the SiH / Vi ratio of the composition is overall 1.5), (E) 66.2 parts of toluene, and (F) 1.0 parts of 3-methyl-1 - Butyn-3-ol was mixed to a uniform consistency to obtain a solvent-containing curable organopolysiloxane composition (Composition 1). Next, the obtained organopolysiloxane composition was diluted with (E) a 50:50% by weight mixture of toluene and hexane to adjust the solid concentration to 3.0% by weight, and (D) chloroplatinic acid / 1, 3-divinyl-1,1,3,3-tetramethyldisiloxane complex (metal platinum content: 0.6% by mass) was added in a certain amount (the amount was ...

[0136] Working Example 2 - Composition 2

[0137] Composition 2 was obtained in a similar manner to Working Example 1, except that the amount of component (B) used in Working Example 1 was changed to 0.4 parts. Using this composition, the ease of applying the ceramic binder resin to the cured layer and the peeling force required to peel the ceramic binder resin from the cured layer were measured. The results are shown in Table 1.

example 3

[0138] Working Example 3 - Composition 3

[0139] Composition 3 was obtained in a similar manner to Working Example 1, except that the amount of component (B) used in Working Example 1 was changed to 3.0 parts. Using this composition, the ease of applying the ceramic binder resin to the cured layer and the peeling force required to peel the ceramic binder resin from the cured layer were measured. The results are shown in Table 1.

Abstract

A curable organopolysiloxane composition comprising: (A) an organopolysiloxane having a form of anywhere from a liquid having a viscosity of 20 mPa.s or greater to a gum that exhibits plasticity,containing the following components a1) and a2) at a mass ratio of 100:0 to 50:50: a1) organopolysiloxane comprising an alkenyl group having 4 to 12 carbon atoms, the alkenyl group having a vinyl moiety content of 0.5 to 3.0 mass%, and a2) organopolysiloxane with an alkenyl group having 2 to 3 carbon atoms, the alkenyl group having a vinyl moiety content of 0.5 to 3.0 mass%; (B) an organopolysiloxane having a form from a liquid having a viscosity of 1,000,000 mPas or greater to a gum that exhibits plasticity, the organopolysiloxane optionally comprising an alkenyl group having 2 to 12 carbon atoms, the alkenyl group having a vinyl moiety content of less than 0.100 mass%; (C) an organohydrogen polysiloxane comprising at least two silicon-bonded hydrogen atoms within its molecule; (D) a hydrosilylation catalyst; and (E) as desired, an organic solvent; the mass ratio of components (A) and (B) being in a range from 90:10 to 99:1.

Description

technical field [0001] The present invention relates to a curable organopolysiloxane composition and a separator for use thereof with a dielectric ceramic layer-forming material, and more particularly to a separator for forming a ceramic green sheet. Background technique [0002] Conventionally, when manufacturing multilayer ceramic products (such as multilayer ceramic capacitors, multilayer inductors, and multilayer ceramic circuit boards), especially multilayer ceramic electronic parts, such a method is known in which The unfired ceramic material is mixed with a binder, a solvent, etc. to form a paste mixture, which is applied to a plastic carrier film and dried to form a dielectric ceramic layer forming material (generally called a "ceramic green sheet"). ” sheet), after which, an internal electrode material having a paste form is printed on a ceramic green sheet to form an internal electrode, and stacked with a plurality of ceramic green sheets so that the electrode patt...
