采用硅烷偶联剂（KH-550）改性磨碎玻璃纤维（MG）和空心玻璃微珠（HGB），制备有机硅改性环氧树脂（YE），以改性MG、改性HGB和改性MG-HGB作为增强材料填充YE，得到3种YE灌封料，比较增强材料对YE灌封料力学性能的影响。结果表明：当制备有机硅低聚物的用水量为理论用水量的0.5倍时，YE灌封料力学性能最佳，与环氧树脂（EP）灌封料相比，拉伸强度提高28.1%，弯曲强度提高35.3%，冲击强度提高266%。与YE灌封料相比，YE/改性MG材料冲击强度降低，YE/改性HGB材料冲击强度升高。YE/改性MG-HGB材料力学性能随改性MG用量比例减小，拉伸强度和冲击强度先升高后降低，弯曲强度一直升高。当YE∶改性MG∶改性HGB质量比为100∶100∶3时，材料力学性能最佳，拉伸强度提高137%，弯曲强度提高42%，冲击强度提高90%。

Silane coupling agent (KH-550) was used to modify milled glass fiber (MG) and hollow glass beads (HGB) to prepare organosilicon-modified epoxy resin (YE). Modified MG, modified HGB, and modified MG-HGB were used as reinforcing fillers to fill YE, resulting in three types of YE encapsulating material. The effects of reinforcing materials on the mechanical properties of YE encapsulating material were compared. The results show that when the water consumption for preparing the organic silicone intermediate is half of the theoretical water consumption, the mechanical properties of the YE encapsulating material are optimal. Compared with the epoxy resin (EP) encapsulating material, the tensile strength is increased by 28.1%, the bending strength is increased by 35.3%, and the impact strength is increased by 266%. Compared with the YE encapsulating material, the impact strength of the YE/modified MG material is decreased, while the impact strength of the YE/modified HGB material is increased. The mechanical properties of the YE/modified MG-HGB material vary with the proportion of modified MG, with tensile strength and impact strength first increasing and then decreasing, while bending strength continues to increase. When the mass ratio of YE∶modified MG∶modified HGB is 100∶100∶3, the mechanical properties of the material are optimal, with tensile strength increased by 137%, bending strength increased by 42%, and impact strength increased by 90%.
