摘要
以双酚A型环氧树脂为基料，正丁基缩水甘油醚为活性稀释剂，3～5mm长的玻璃纤维为增强材料，在氨基聚酰胺＋水杨酸固化体系中合成了玻璃钢涂层。研究了稀释剂、固化剂和固化促进剂的用量对涂层表干时间和固化时间的影响，玻璃纤维的用量对涂层耐蚀性和耐磨性的影响。获得了最佳配方：32g双酚A型环氧树脂，10g氨基聚酰胺，1．6g水杨酸，5g正丁基缩水甘油醚，5g玻璃纤维，1.3g邻苯二甲酸二丁酯（增塑剂）。以此玻璃钢作为管道内涂层材料，满足了输送管道耐腐蚀和耐磨性的要求。
A coating of glass fiber reinforced plastic was synthesized with bisphenol A epoxy resin as substrate material, n-butyl glycidyl ether as active thinner, glass fiber of 3 - 5 mm in length as reinforcement and amino-polyamide ＋ salicylic acid as curing system. The effects of the dosages of thinner, curing agent and accelerator on coating＇s surface drying time and curing time, and the effect of the quantity of glass fiber on coating＇s corrosion resistance and wear resistance were studied. The optimal formula was gained as follows： bisphenol A epoxy resin 32 g, polyamide 10 g, salicylic acid 1.6 g, n-butyl glycidyl ether 5 g, glass fiber 5 g, di-n-butyl phthalate （plasticizer） 1.3 g. The internal coating material with glass fiber reinforced plastic thus obtained can fulfill the demand of corrosion resistance and wear resistance on transportation pipeline.
