摘　　要：借鉴陶瓷坯体挤出成型工艺,提出了固体浮力材料挤出成型方法,优化了固体浮力材料挤出成型工艺参数。以环氧树脂为基体,空心玻璃微珠(HGMS)为填充材料,采用挤出成型自由固化方法制备高HGMS含量的固体浮力材料,并对其性能进行了研究。结果表明:挤出成型自由固化方法适用于HGMS体积分数为66%~68%固体浮力材料的制备。工艺参数优化后,制得HGMS体积分数为67%和68%的固体浮力材料,密度分别为0.648 g/cm^(3)和0.635 g/cm^(3),抗压强度为80.0 MPa和59.8 MPa,可使用深度为12000 m和8000 m,最大吸水率均不超过0.55%。The extrusion molding method of solid buoyancy material was put forward referring to the extrusion molding process of ceramic,and the extrusion process parameters of solid buoyancy material were optimized.The solid buoyancy material with high HGMS(hollow glass microsphere)volume fraction was prepared by extrusion molding with epoxy resin as matrix and HGMS as filler,and the properties of the materials were studied.The results show that the extrusion and free curing method is suitable for the preparation of solid buoyancy materials with HGMS volume fraction of 66%~68%.Under the optimized process parameters,the solid buoyancy materials with HGMS volume fraction of 67%and 68%are prepared,and the density of the materials are 0.648 g/cm^(3) and 0.635 g/cm^(3),and the compressive strength of the material are 80.0 MPa and 59.8 MPa respectively.The usable depth of the material are 12000 m and 8000 m,respectively,and the maximum water absorption is not more than 0.55%.
