摘要

摘要: 借鉴陶瓷材料模压成型工艺提出了适用于环氧树脂基固体浮力材料制备的真空辅助模压成型自由固化方法，实现了固体浮力材料制备过程中成型与固化环节的分离，为高性能固体浮力材料的制备提供了新方法。以环氧树脂(E-4221)为基体，空心玻璃微珠(Hollow glass microsphere, HGMS)做填充材料，采用模压成型自由固化方法制备高HGMS体积分数的HGMS/E-4221固体浮力材料，研究了HGMS体积分数、成型压力对HGMS/E-4221固体浮力材料密度、抗压强度、吸水率等性能的影响。结果表明，真空辅助模压成型自由固化方法适用于HGMS体积分数为65%~67%的HGMS/E-4221固体浮力材料制备，所获得的HGMS/E-4221固体浮力材料密度为0.621~0.655 g/cm³，适用深度可达到8 000~10 000 m。

Abstract: A vacuum-assisted compression molding and free curing method suitable for the preparation of epoxy resin-based solid buoyancy materials was proposed by learning from the ceramic material molding process, which realized the separation of molding and solidification during the preparation of solid buoyancy materials and provided a new method for the preparation of high performance solid buoyancy materials. The epoxy resin (E-4221) was used as the matrix, and the hollow glass microsphere (HGMS) was used as the filling material. The HGMS/E-4221 solid buoyancy material with high HGMS volume fraction was prepared by compression molding and free curing method. The effects of volume fraction of HGMS and molding pressure on the density, compressive strength and water absorption of HGMS/E-4221 solid buoyancy materials were studied. The results show that the vacuum-assisted compression molding and free curing method is suitable for the preparation of HGMS/E-4221 solid buoyancy materials with HGMS volume fraction of 65%-67%. The obtained HGMS/E-4221 solid buoyancy material has a den-sity of 0.621-0.655 g/cm³ and a suitable depth of 8 000-10 000 m.
