Problems solved by technology

However, there is a problem that the resistance of the organic EL element to moisture is very weak, and the light-emitting material (light-emitting layer) is deteriorated due to water, and the luminance is lowered, or it no longer emits light, or the interface between the electrode and the light-emitting layer is Delamination occurs under the influence of moisture, or metal oxidation increases resistance

Embodiment

[0137] Hereafter, although an Example demonstrates this invention concretely, this invention is not limited to these Examples. In the following description, unless otherwise specified, "%" and "part" other than the reaction rate and thermal weight loss rate of the cured product represent "mass%" and "mass part", respectively. As the hydrotalcites, all commercially available hydrotalcites whose saturated water absorption rate, thermal weight loss rate, and X-ray diffraction peak were measured were used.

[0138]

[0139] The following steps were used to synthesize N-acetylglycine tetrabutylphosphonium salt as an ionic liquid curing agent. To 20.0 g of a 41.4% tetrabutylphosphonium hydroxide aqueous solution (manufactured by Hokko Chemical Industry Co., Ltd.), 3.54 g of N-acetylglycine (manufactured by Tokyo Chemical Industry Co., Ltd.) was added at 0° C., and stirred for 10 minutes . Using an evaporator, the reaction solution was concentrated at 60 to 80° C. for 2 hours at ...

Embodiment 2

[0144] Instead of hydrotalcite A (22 parts), hydrotalcite B (BET specific surface area 15m 2 / g, 15 parts), except that, it was carried out similarly to Example 1, the thermosetting resin composition varnish was manufactured, and the sheet|seat for sealing was obtained.

Embodiment 3

[0146] Instead of hydrotalcite A (22 parts), hydrotalcite A (14 parts) and hydrotalcite C (BET specific surface area 146m 2 / g, 5 parts) mixed hydrotalcite (BET specific surface area 48m 2 / g) except that, it carried out similarly to Example 1, the thermosetting resin composition varnish was manufactured, and the sheet|seat for sealing was obtained.

Abstract

The present invention provides a thermosetting resin composition for sealing, which contains (A) a thermosetting resin, (B) a curing agent and (C) semi-calcined hydrotalcite as an inorganic filler, wherein when the thermogravimetric loss rate prior to moisture absorption, as measured by thermogravimetric analysis, at 280 DEG C of a cured product of the thermosetting resin composition is denoted byX1 (%), the thermogravimetric loss rate prior to moisture absorption of the cured product at 380 DEG C is denoted by Y1 (%), the thermogravimetric loss rate following moisture absorption, as measuredby thermogravimetric analysis, at 280 DEG C of the cured product of the thermosetting resin composition is denoted by X2 (%) and the thermogravimetric loss rate following moisture absorption of the cured product at 380oC is denoted by Y2 (%), the relationships 2% <= X2-X1 and Y2-Y1 <= 10% are satisfied and the overall content of inorganic filler, including semi-calcined hydrotalcite, is 20-60 mass% relative to the overall quantity of non-volatile components in the thermosetting resin composition.

Description

technical field [0001] The present invention relates to a thermosetting resin composition for sealing and a sheet for sealing, and particularly relates to a thermosetting resin suitable for sealing light-emitting elements such as organic EL (Electroluminescence) elements, and photoelectric conversion elements such as light-receiving elements such as solar cells. Composition and sheet for sealing. Background technique [0002] An organic EL element is a light-emitting element using an organic substance as a light-emitting material, and has attracted attention in recent years because it can obtain high-intensity light emission at a low voltage. However, there is a problem that the resistance of the organic EL element to moisture is very weak, and the light-emitting material (light-emitting layer) is deteriorated due to water, and the luminance is lowered, or it no longer emits light, or the interface between the electrode and the light-emitting layer is Peeling occurs under t...
