摘要/Abstract

摘要： 采用湿热老化、冻融循环及紫外老化等加速试验方法,通过质量变化率、弯曲强度保留率及SEM分析,对189不饱和聚酯玻璃钢及MFE-2环氧乙烯基酯玻璃钢在海洋环境中的腐蚀机理和耐久性进行了详细研究。试验结果表明,湿热老化150d后,189不饱和聚酯玻璃钢及MFE-2环氧乙烯基酯玻璃钢的质量变化率分别为-6.03%和0.31%,弯曲强度保留率分别为26.2%和47%;紫外老化300h后,弯曲强度保留率分别为84%和94%;1000次冻融循环后,弯曲强度保留率分别为30%和65%。基体树脂分子链上酯基的密度是影响玻璃钢在海洋环境中耐久性的关键因素,MFE-2环氧乙烯基酯树脂分子链上酯基的密度约为189不饱和聚酯树脂分子链上酯基密的1/3,所以MFE-2环氧乙烯基酯玻璃钢在海洋环境中具有更好的耐久性。

Abstract: In recent years, GFRP composites are gradually used to wrap ocean engineering structures, which act as substitutes of anti-corrosion paints or coatings, working as protective layers to prolong the service life of these ocean engineering structures. In order to research the durability of GFRP composites in ocean environment, hydrothermal aging, freeze-thaw aging and ultraviolet aging were adopted to study the corrosion behavior of glass fiber-reinforced plastics composites in ocean environment. The mass variation rate, retention rate of bending strength and SEM were used to analyze the corrosion mechanism and durability of 189 unsaturated polyester resin based and MFE-2 epoxy vinyl ester resin based glass fiber-reinforced plastics (GFRP) composites. The results show that the number of ester group on the resin molecular chain is the main factor that affects the durability of GFRP composites in ocean environment. The number of ester group on the MFE-2 epoxy vinyl ester resin molecular chain is about 1/3 of the 189 unsaturated polyester resin. To be concludes, the MFE-2 GFRP possesses better durability in ocean environment.

Key words: unsaturated polyester resin, epoxy vinyl ester resin, glass fiber-reinforced plastics composites, seawater corrosion resistance
