摘要
以GELR-128环氧树脂为基体树脂,石英砂为填料,双氰胺为固化剂,咪唑为促进剂,添加活性稀释剂烯丙基缩水甘油醚(AGE)和偶联剂(KH-550)等制备了环氧树脂人造大理石。通过红外光谱,电镜分析及力学性能、耐酸碱性和热老化性能测试研究了填料粒径大小和用量对环氧人造大理石性能的影响。结果表明,使用混合粒度的石英砂为填料,添加质量分数90%,固化工艺为80℃/1 h+120℃/1 h时,制得的环氧人造大理石冲击强度可达5.13 k J/m2,且具有较好的耐酸碱腐蚀和耐热老化性。
The epoxy resin artificial marble was prepared using GELR-128 epoxy resin as matrix resin,quartz sand as filler,dicyandiamide as curing agent,imidazole as curing catalyst and adding reactive diluents allyl glycidyl ether（AGE）and coupling agent（KH-550）. The effects of filler particle size and amount on the properties of epoxy artificial marble were investigated by the FTIR,SEM and testings of mechanical property,heat acid and alkali resistance and aging resistance. The results showed that the impact strength of epoxy artificial marble was up to 5.13 k J/m^2 and the marble had good acid and alkali resistance and heat aging resistance as the conditions as followed：mixed particle size quartz sand as filler,mass fraction 90% and curing at 80 ℃ 1 h＋120 ℃ 1 h.
