Description

technical field [0001] The invention relates to a phenyl silicone rubber composite material modified by sodium aluminum silicate and a preparation method thereof. Background technique [0002] With the continuous improvement of the power and brightness of light-emitting diodes (LEDs), the existing packaging materials are far from meeting the requirements in terms of reliability, life and performance. Therefore, research institutions at home and abroad are developing organic materials for LED packaging with better performance. . Compared with the traditional epoxy resin and polyurethane packaging materials used in LED packaging, silicone resin has high light transmittance (light transmittance greater than 98% in the visible light range) and good thermal stability (can withstand temperature 200 ℃) , low stress (low Young's modulus) and low moisture absorption (less than 0.2%) and other characteristics, it is recognized as an electronic packaging material with excellent perfor...
