Abstract

The aim of this research was a comparative analysis of selected mechanical properties of epoxy compounds that were modified with metallic fillers and aged in aqueous environments. The tested epoxy compounds consisted of three components: styrene modified epoxy resin based on Bisphenol A, triethylenetetramine curing agent (resin/curing agent ratio of 100:10) and two types of metallic fillers in the form of particles: aluminum alloy (EN AW-2024-AlCu4Mg1) and tin-phosphor bronze (CuSn10P). Samples were subjected to ageing in 4 water environments: low-, medium- and high-mineralized natural water and in a sugar-containing solution for 1, 2 and 3 months. The epoxy samples were subjected to compressive strength tests in accordance with the ISO 604:2002 standard. It was observed that, among others, the compositions seasoned in low-mineralized water usually achieved the highest average compressive strength. As for filler type, using the bronze filler (CuSn10P) usually achieved the highest average compressive strength results.

摘要

本研究的目的是对用金属填料改性并在水环境中老化的环氧化合物的选定机械性能进行比较分析。所测试的环氧化合物由三种成分组成：基于双酚A的苯乙烯改性环氧树脂、三亚乙基四胺固化剂（树脂/固化剂比例为100:10）以及两种颗粒形式的金属填料：铝合金（EN AW-2024-AlCu4Mg1）和锡磷青铜（CuSn10P）。样品在4种水环境中老化：低矿化度、中矿化度和高矿化度的天然水以及含糖溶液，老化时间为1、2和3个月。根据ISO 604:2002标准对环氧样品进行抗压强度测试。结果发现，在低矿化度水中老化的组合物通常具有最高的平均抗压强度。至于填料类型，使用青铜填料（CuSn10P）通常能获得最高的平均抗压强度结果。
