摘要:

以雙酚A環氧樹脂E51為基質原料，甲基四氫苯酐為固化劑，K25空心玻璃微珠為輕質填充物，采用模壓成型的方法制備了具有空心玻璃微珠填充固體浮力材料。研究了玻璃微珠的填充率對體系粘度、浮力材料的密度、抗壓強度及耐靜水壓性能的影響。結果表明，低密度空心微珠的引入，有效降低了固體浮力材料的密度，并且隨著玻璃微珠填充量的增大，材料的理論計算密度與實際密度的偏差逐漸變大;浮力材料的單軸壓縮強度和耐靜水壓強度隨著空心玻璃微珠填充量的增大而降低，當玻璃微珠填充量超過18%時，材料性能下降幅度增大。

Abstract:

Solid Buoyancy Materials with different content of hollow glass microspheres was synthesized by molded forming, withbisphenolepoxy resin E51 as bulk material, methyl tetrahydrophthalic anhydride as the curing agent, hollow glass microspheres named K25 as lightweight filler. The influence of the content of glass microsphereson density, uniaxial compressive strength and resistance to hydrostatic pressure of solid buoyancy materialwas studied. The results showed that the introduction of microspheres with lower density could reduce the density of solid buoyancymaterial effectively. With the increasing of hollow glass microsphere content, the deviation between theoretical density and actual density increased, and the uniaxial compressive strength and resistance to hydrostatic pressure of solid buoyancy material decreased. Especially, when the content of hollow glass microsphere exceed 18%, the decrease amplitude of the uniaxial compressive strength and resistance to hydrostatic pressure increased.
