摘　　要： 研究绝缘导热加成型有机硅灌封胶的制备及性能。结果表明:当采用粘度为300和1 000 m Pa·s的端乙烯基硅油以质量比40∶60复配、选用活性氢质量分数为0.005 0的含氢硅油且硅氢基/硅乙烯基摩尔比为1.2时,有机硅灌封胶的物理性能较佳;当三氧化二铝用量为150份时,有机硅灌封胶具有良好的综合性能。 In this study,the electrical insulating and thermal conductive addition-cure silicone encapsulant was prepared and its properties were investigated. The results showed that,when the mass ratio of vinyl end silicone oils with viscosity of 300 and 1 000 m Pa·s was 40∶60,active hydrogen mass fraction of hydrogen-containing silicone oil was 0. 005 0 and molar ratio of Si H and Si Vi was 1. 2,the physical properties of silicone encapsulant were good. When the addition level of Al2O3 was 150 phr,the silicone encapsulant had good comprehensive performance.
