以环氧树脂为基体,空心玻璃微珠为填充物制备得到轻质高压浮力材料。采用排水法计算浮力材料的密度,变容深海耐压模拟试验装置测试了浮力材料在高压环境下的吸水率。结果表明:随着空心玻璃微珠含量的增加,浮力材料的密度下降,同一静水压下浮力材料吸水率先缓慢增加后急速升高;不同静水压条件下,材料的吸水率在40MPa以下基本不变,高于40MPa时,材料的吸水率急剧升高。 Epoxy resin as a matrix, hollow glass beads for the filler to prepare light high-pressure buoyancy material. Using the drainage method to calculate the density and buoyancy of the buoyant material, the deep sea pressure simulation test device tests the water absorption of the buoyant material in the high pressure environment. The results show that the density of buoyant material decreases with the increase of the content of hollow glass microbeads. The water absorption of buoyant material firstly increases slowly and then increases rapidly under the same hydrostatic pressure. Under different hydrostatic pressure, the water absorption of material under 40 MPa Unchanged, higher than 40MPa, the material’s water absorption rose sharply.
