Embodiment

[0325] The following examples will be shown to describe the present invention concretely. However, the present invention is not limited by these Examples.

[0326]

[0327] 1. Polysiloxane 2

[0328] Install a stirrer and a reflux condenser in a 500mL 3-neck flask, add polysiloxane (polydimethylsiloxane-α,ω-diol, weight average molecular weight 49,000, trade name ss10) having silanol groups at both ends , manufactured by Shin-Etsu Chemical Co., Ltd. The same applies below.) 100 parts by weight, 10 parts by weight of tetramethoxysilane, and 0.1 parts by weight of acetic acid were reacted at 100° C. for 6 hours in a nitrogen atmosphere. pass 1 In H-NMR analysis, the disappearance of the silanol group possessed by ss10 was confirmed. The obtained organosiloxane was referred to as polysiloxane 2. The main structure of polysiloxane 2 is represented by the following formula. Polysiloxane 2 is both terminal trimethoxysilyl siloxane. The weight-average molecular weight (the we...

Abstract

The purpose of the present invention is to provide a silicone resin composition with excellent transparency and sulfuration resistance. Provided is a silicone resin composition comprising 0.01-5 parts by mass, per 100 parts by mass of a curable silicone resin compound (A), of a zinc compound (B) obtained by reacting 1.5 mol or more but less than 2 mol acid with 1 mol of at least one type selected from a group comprising zinc oxide, zinc carbonate, zinc hydroxide, zinc chloride, zinc sulfate, and zinc nitrate. Also provided is a method for using a silicone resin-containing structure, an optical semiconductor element sealed body, and the silicone resin composition, that use same.

Description

technical field [0001] The present invention relates to a silicone resin composition, a silicone resin-containing structure using the composition, an optical semiconductor element sealing body, and a method for using the silicone resin composition. Background technique [0002] Silicone resins are excellent in heat resistance, but have higher gas permeability than epoxy resins and the like. Therefore, there is a problem that the silver plating layer to which the silicone resin is applied is discolored and corroded over time due to hydrogen sulfide in the air. As countermeasures against discoloration over time, a method of increasing the crosslink density of a silicone resin to make the resin hard, and a method of copolymerizing a silicone resin with a resin having high gas barrier properties have been proposed (see, for example, Patent Document 1). [0003] In addition, the applicant of the present application has hitherto disclosed a silicone resin combination containing, ...
