以环氧树脂E-4221为基质原料,十二烯基琥珀酸酐和甲基四氢苯酐为固化剂,以牌号为K20和HGS8000X两种空心玻璃微珠为轻质填充物,采用模压成型的方法制备了具有不同空心玻璃微珠配比的固体浮力材料。研究了玻璃微珠的配比对浮力材料的密度、抗压强度、吸水率及耐静水压性能的影响。结果表明,低密度空心微珠的引入,有效降低了固体浮力材料的密度;混合微珠填充更有利于固体浮力材料密度的降低;两种不同微珠相互配合可以得到适用于不同深度的高性能固体浮力材料。
Epoxy resin E-4221 as the matrix material, dodecenyl succinic anhydride and methyl tetrahydrophthalic anhydride as curing agent, two kinds of hollow glass beads with K20 and HGS8000X as light-weight filler, using molding method Solid buoyant materials with different hollow glass bead ratios were prepared. The effects of the ratio of glass beads on the density, compressive strength, water absorption and hydrostatic resistance of buoyant materials were studied. The results show that the introduction of low density hollow microbeads effectively reduces the density of solid buoyant materials; the mixing microbead filling is more conducive to the reduction of the density of solid buoyant materials; the two different microbeads cooperate to obtain the high performance Solid buoyancy material.
