摘要
以环氧树脂为基体,选用低分子聚酰胺树脂为固化剂,液体聚硫橡胶为增韧剂,并填充经表面活化处理的空心玻璃微珠,制得高强度、低密度、低吸水率的深海浮力材料。结果表明,随着空心玻璃微珠用量的增加,深海浮力材料的密度、压缩强度和冲击强度均逐渐降低,而吸水率上升。当固化剂TY–203的质量分数为环氧树脂的1/2、增韧剂液体聚硫橡胶的质量分数为10%、改性空心玻璃微珠的质量分数为35%时,制得深海浮力材料的综合性能较好,密度为0.633 g/cm3、压缩强度为45.21 MPa、冲击强度为36.39 J/m、吸水率为0.67%。
The deep-sea buoyancy materials with high strength, low density and low water absorption were prepared by mixing great amount of the activated hollow glass bead in epoxy resin. Low molecular weight polyamide was chosen as curing agent and the composite was toughened by liquid polysulfide rubber in the process of preparation. The results show that with content of the hollow glass bead increasing, the density, compressive strength and impact strength of buoyancy materials decrease, however, the water absorption of buoyancy materials increase. When the mass fraction of curing agent is 1 / 2 of epoxy resin, the mass fraction of toughening agent is 10%, and the mass fraction of modified hollow glass bead is 35%, the deep-sea buoyancy material has better comprehensive properties, the density, compressive strength, impact strength and water absorption are 0.633 g/cm3, 45.21 MPa, 36.39 J/m and 0.67% respectively.
