摘　　要：以三聚氰胺与甲醛为原料,制备了三聚氰胺甲醛树脂,采用间歇法工艺将发泡聚苯乙烯(EPS)微球填充到三聚氰胺甲醛树脂基体中制备了三聚氰胺甲醛树脂基固体浮力材料,对浮力材料的断面微观结构、力学性能、吸水率和压缩强度进行了测试与分析,并对影响浮力材料密度的EPS微球粒径和影响浮力材料储能模量的EPS微球含量进行了研究。结果表明:随着静水压力的增加,固体浮力材料的吸水率增大,当静水压力超过80 MPa时,固体浮力材料结构受到明显破坏,吸水率急剧上升;该固体浮力材料的水下性能良好,力学性能和动态力学性能也符合基础应用要求。Melamine formaldehyde resin was prepared with melamine and formaldehyde as raw materials,which was filled with expandable polystyrene(EPS)microspheres to prepare melamine formaldehyde resin-based solid buoyancy material via intermittent process.The cross-sectional microstructure,mechanical properties,water absorption rate,and compressive strength of the buoyancy material were tested and analyzed.The particle size of EPS microspheres that affects the density of the buoyancy material and the content of EPS microspheres that affects the energy storage modulus of the buoyancy material were discussed.The results show that with the increase of hydro static pressure,the water absorption rate of buoyancy materials increases.When the static water pressure exceeds 80 MPa,the structure of buoyancy materials is significantly damaged,and the water absorption rate increases sharply.The material performs excellently underwater,whose mechanical properties and dynamic mechanical properties meet the basic application requirements.
