摘　　要：　采用丙烯酸改性酚醛环氧树脂,并对以此树脂为基体,以DDSA为增韧剂研制成功一种耐酸性玻璃钢拉挤电绝缘芯棒用树脂基体配方。应用DSC、TGA和FT-IR等分析技术对该改性树脂基体的固化反应进行了研究,对其浇铸体以及玻璃纤维增强的拉挤芯棒的耐酸性、耐热性等性能也进行了研究。结果表明:该树脂基体满足拉挤工艺要求,用此树脂基体制得的玻璃钢拉挤芯棒具有优异的耐酸性以及良好的机电热性能。By using acrylic acid to modify phenolic epoxy resin, an acid resistant resin matrix formulation for pultrusion insulant rod which was toughened by DDSA was optimized. The curing reaction of the modified epoxy resin system was studied by DSC, TGA and FT-IR. The acid resistance, heat resistance, mechanical and electrical properties of the cured compound epoxy resin (cast) and the glass fiber reinforced epoxy resin matrix pultrusion rod were also studied. Experiments show that the resin matrix is suited for pultrusion, and the properties of the insulant rod are excellent.
