摘　　要：深海复合泡沫材料广泛应用于海洋开发、深海勘探等众多领域,除了提供浮力外,还能用于某些复杂结构的防腐保护。在复合泡沫材料树脂基体组成中,环氧树脂占有十分重要的地位。本文通过对双酚A、双酚F、氢化双酚A和混合型环氧树脂在静水压下的吸水性研究,考察了环氧值、主链柔顺性、侧基柔顺性和特殊基团结构对树脂性能影响。结果表明环氧值低的双酚A树脂吸水率较高,主链和侧基的柔顺性有利于树脂吸水,同时含有酯基基团环氧树脂吸水率较高。Abysmal sea syntactic foams are widely used in many fields of marine development, deep-sea exploration. Besides providing buoyancy, the foams also protect the complex structures from marine corrosion. In composite foam resin matrix composition, the epoxy resin occupies a very important position. We studied the influence of bisphenol A, bisphenol F, hydrogenated bisphenol A or mixed type epoxy resin on water absorption to investigate the effect of epoxy value, the main chain flexibility, pendant group and special group structure on resin properties under hydrostatic pressure. The results indicated that bisphenol A epoxy with lower epoxy value could lead to higher water absorption, flexibility backbone and side groups was beneficial to the absorption of resin, while the epoxy containing ester group exhibited high water absorption.
