preparation example Construction

[0082] [Preparation method of silylated modified isocyanurate compound]

[0083] The silylated modified isocyanurate compound of the present invention can be produced, for example, by subjecting triglycidyl isocyanurate to a hydrolysis reaction with chlorosilane and alkoxysilane. The conditions of the hydrolysis reaction only need to be properly adjusted. For example, the reaction ratio of epoxy group to trimethylchlorosilane is 1:1 in molar ratio.

[0084] [anticorrosion agent]

[0085] The silylated isocyanurate compound of the present invention can exhibit an excellent effect as a metal corrosion inhibitor. Therefore, it is preferable to prepare a metal anticorrosion agent containing the silylated isocyanurate compound of the present invention.

[0086] When the silylated isocyanurate compound of the present invention is used as a corrosion inhibitor, it may be added in an amount of 0.001 to 5% by mass, preferably 0.01 to 3% by mass based on the resin composition. The c...

Synthetic example

[0212] 297.3 g (1.0 mol) of triglycidyl isocyanurate was added to the reaction vessel, and dissolved in 350 g of toluene. 217.3 g (2.0 mol) of trimethylchlorosilane was added thereto, and the temperature was raised to 80°C. 18 g (1.0 mol) of water was added dropwise thereto over 30 minutes. After completion of the dropwise addition, the mixture was further heated and stirred at 80° C. for 3 hours. In addition, tris(pentafluorophenyl)borane was added as a reaction catalyst to carry out a chemical reaction.

[0213] After completion|finish of heating, it cooled to room temperature (25 degreeC), and it washed with water using 10 mass % sodium sulfate aqueous solution. Then, 50 g of magnesium-aluminum solid solution (trade name: KW-2200, manufactured by Kyowa Chemical Industry Co., Ltd.) was added, and stirred at 25° C. for 1 hour to remove tris(pentafluorophenyl)borane by adsorption. KW-2200 was removed by pressure filtration, and the residual solvent was distilled off under r...

Embodiment 2

[0269] Add the following ingredients and stir thoroughly to prepare a curable silicone resin composition:

[0270] (A1) Composition: 75mol% PhSiO 3 / 2 unit, 25mol% ViPhMeSiO 1 / 2 Branched-chain phenylmethylpolysiloxane composed of units (Mw=2,500, the amount of hydroxyl groups bonded to silicon atoms is 0.04 mol / 100g, and the amount of alkoxy groups bonded to silicon atoms is 0.06 mol / 100g) , which is 30 copies;

[0271] Component (B): An organohydrogenpolysiloxane represented by the following formula (6), in which the total number of hydrogen atoms bonded to silicon atoms in the component (B) is relative to the components (A) and (D) The ratio of the total number of silicon atom-bonded vinyl groups (hereinafter, sometimes expressed as SiH / SiVi ratio) is the amount of 1.0;

Abstract

The purpose of the present invention is to provide a silylated isocyanurate compound which can function as a metal anticorrosive agent having excellent heat resistance and vulcanization resistance, i.e., a silylated isocyanurate compound represented by general formula (1). In general formula (1), R independently represents a substituent selected from a hydrogen atom, an alkyl group having 1-10 carbon atoms, an alkenyl group having 2-10 carbon atoms, and a group represented by general formula (2-a) or general formula (2-b), and at least one R represents a general formula (2-b).

Description

technical field [0001] The present invention relates to a silylated isocyanurate compound used as a metal corrosion inhibitor, a curable silicone resin composition, and a semiconductor device. Background technique [0002] In recent years, optical semiconductor devices have been used as LED lighting such as outdoor lighting and vehicle lighting. As a sealing material for such an optical semiconductor device, a resin having high air permeability or water permeability, such as silicone resin, is generally used. Therefore, in harsh environments such as outdoors, there is a problem that the silver plating layer used as an electrode or a reflective layer of an optical semiconductor device is corroded by sulfur-based gases or moisture, resulting in a significant decrease in brightness. [0003] As a countermeasure, it has been studied to increase the refractive index and improve the gas barrier properties by introducing aromatic substituents such as phenyl groups (Patent Document...
