摘要
采用聚氨酯、中空玻璃微球和纳米材料3种方式对环氧电子灌注材料进行了改性,研究了改性方式对密度、冲击韧性和压缩性能的影响。结果表明:中空玻璃微球改性时密度降低最大,比纯环氧降低了20%左右,密度达到近1.0g/cm^3,聚氨酯改性的冲击韧性最高,纳米材料改性能显著提高压缩性能。
Modification is performed to electronic epoxy potting materials by three methods of polyurathane, hollow glass microballoon and nano-powder,and the effects of modification on the density, impact toughness and compression properties of modified materials are studied. The results show that the modification of hollow glass microbal- loon can lower the density at the most, which reached to about 1.0g/cm^3, about 20% lower than that of single epoxy resin. The modification of polyurathane can elevate the impact toughness highest, and the modification of nano-powder can improve the compression properties obviously.
