Problems solved by technology

However, in the environment where LEDs are used, the sulfur in the air will gradually penetrate the encapsulant into the interior of the LED component, and react with the silver layer on the bracket, causing the silver layer to vulcanize to produce black silver sulfide, thus reducing the light output of the LED.

[0064] Preparation Example 1: Preparation method of linear polysiloxane (A)_compound 1

[0065] 3499.92 grams (19.13 mole) of methylphenyl dimethoxysilane (phenylmethyldimethoxysilane, purchased from Hengqiao Industrial Co., Ltd., Taiwan), 288.48 grams (2.4 mole) of dimethyldimethoxysilane (Dimethyldimethoxysilane, Purchased from Hengqiao Industrial Co., Ltd., Taiwan), and 317.28 grams (2.4mole) of methylvinyldimethoxysilane (Methylvinyldimethoxysilane, purchased from Liuhe Chemical Co., Ltd., Taiwan) was added to the reactor and placed in Stir evenly at room temperature to form a mixed solution. This mixed solution was dripped into 5337.4 grams of sulfuric acid aqueous solution with a mass concentration of 5% to obtain a reaction solution. Then, the reaction solution was heated to 75° C. to carry out the hydrolysis reaction. After the reaction was complete, it was extracted to the organic layer with deionized water. The pH is neutral; finally, the solvent is removed to obtai...
