| 摘 要： | 采用硅烷偶联剂KH-560对氮化硼(BN)进行表面处理,用于制备BN/环氧树脂导热灌封胶。结果表明,随着BN用量的增加,环氧导热灌封胶的剪切强度下降,导热性能则增加,表面改性有助于提高环氧灌封胶的剪切强度和导热性能。CTBN的加入可有效提高剪切强度。当改性BN和CTBN质量分数均为15%时,BN/环氧灌封胶具有较理想的剪切强度、热性能和导热性能。

| Abstract: | The boron nitride （BN） micro particles treated with silane coupling agent KH-560 were performed to prepare the thermal conductive BN/epoxy pouring sealant by blending-casting method.The results showed that with increasing mass fraction of BN,the shear strength of epoxy pouring sealant was decreased,however,the thermal conductivity was increased.Both the shear strength and the thermal conductivity of the epoxy sealant were further improved after treating of BN.Meanwhile,the shear strength was obviously improved by adding CTBN.The BN/epoxy pouring sealant had ideal shear strength,thermal properties and good thermal conductivity properties by adding 15wt% treated BN and 15wt%CTBN. |
