摘要: 对低酯基密度双酚A型乙烯基酯树脂(MFE 711型)在80 ℃碱溶液中的腐蚀性能进行研究,同等实验条件下与其他类型树脂耐腐蚀性能进行对比,碱液介质为质量分数为25%的氢氧化钠(NaOH)溶液。试验证明低酯基密度乙烯基酯树脂在高温条件下具有优异的耐碱性能,经25% NaOH浸泡600 d,弯曲强度保留率为75%,弯曲模量保留率为105%,质量保留率为98.6%,有效厚度变化率小于0.5%,巴柯尔硬度保留率为108%。

Abstract: Corrosion resistance of five different types of vinyl ester resin and unsaturated polyester resin was tested under the same experimental conditions in order to compare the corrosion resistance of low ester density in alkali with other different type resin. The alkali was sodium hydroxide (NaOH) solution, for which the mass fraction was 25% and temperature is 80 ℃. The test proved that low ester density had excellent alkali resistance at high temperature. The flexural strength retention rate is 75%, the flexural modulus retention rate is 105%, the mass retention rate is 98.6%, effective thickness change rate is less than 0.5%, and barcol hardness retention rate was 108% after soaking 600 days in 25% NaOH solution.

Key words: vinyl ester resin, VE, alkali corrosion resistance, strength retention rate, NaOH solution
