全海深浮力材料的研究与制备

Study on and Preparation of Full Ocean Depth Buoyancy Materials

选用缩水甘油醚型环氧树脂、芳香族多胺固化剂和空心玻璃微珠等原材料制备了低密度、高强度的全海深浮力材料,研究了低密度空心玻璃微珠K1的加入量对浮力材料的密度、单轴压缩强度、耐静水压强度和吸水率等性能的影响。结果表明,在空心玻璃微珠总体积分数为66.7%的全海深浮力材料中,加入适量空心玻璃微珠K1取代空心玻璃微珠HM42,能够降低全海深浮力材料的密度,浮力材料的单轴压缩强度不低于132 MPa,耐静水压强度不低于150 MPa,吸水率不高于0.2%。制备的全海深浮力材料有望满足全海深设备的安全使用。

Full ocean depth buoyancy materials were prepared with glycidyl ether type epoxy resin, aromatic polyamine hardener and hollow glass bubbles. Here were investigated the influences of the volume fraction of hollow glass bubbles K1 on such performances as density, compressive strength, resistance to hydrostatic pressure and water absorption rate. The results showed that when the total volume fraction of the hollow glass bubbles in the full ocean depth buoyancy material was 66.7%, the introduction of appropriate amount of hollow glass bubbles K1 instead of HM42 could reduce the density of full ocean depth buoyancy material, the compressive strength was not less than 132 MPa, the resistance to hydrostatic pressure was not less than 150 MPa, and the water absorption rate was not higher than 0.2%. It’s prospective to meet the safe usage of full ocean depth equipments.
