中文摘要:
      以粘度为300mPa.s和1000mPa.s的端乙烯基硅油复配,含氢硅油为交联剂,氧化铝(Al2O3)为导热填料,氢氧化铝(Al(OH)3)为阻燃剂,制备了无卤阻燃导热加成型有机硅灌封胶,研究了氢氧化铝对导热加成型有机硅灌封胶性能的影响。结果表明,随着氢氧化铝用量的增加,加成型有机硅灌封胶的阻燃性能和导热性能提高,粘度增大,体积电阻率和力学性能下降。当Al(OH)3用量为60份时,加成型有机硅灌封胶的综合性能最佳。
英文摘要:
      Halogen-free flame retardant and thermal conductive addition-cure silicone encapsulant was prepared using complex of vinyl end silicone oils with viscosity of 300mPa.s and 1000mPa.s, hydrogen silicone oil as cross-linker, alumina (Al2O3) as thermally conductive filler, aluminium hydroxide (Al(OH)3) as flame retardant. The effect of aluminium hydroxide on properties of thermal conductive addition-cure silicone encapsulant was investigated. The results showed that with the increase of the amount of Al(OH)3, flame retardancy and thermal conductivity of the encapsulant enhanced, viscosity of the encapsulant increased, and volume resistivity and mechanical properties of the encapsulant decreased. When the content of Al(OH)3 was 60phr, silicone encapsulant showed good comprehensive performance.
