摘要
采用重交70#沥青、聚丙二醇、脂肪族缩水甘油醚环氧树脂、芳香族酸酐和二聚脂肪酸酐(5个因素)及E-51环氧树脂制得环氧沥青材料。设计了五因素四水平正交实验,以拉伸强度和断裂伸长率为主要考核指标,研究了沥青、活性增容剂、固化剂等主要因素对环氧沥青材料力学性能的影响,并优化出最佳配方:10.0 gE-51双酚A环氧树脂,52.0 g重交70#沥青,1.5 g芳香族酸酐,8.0 g二聚脂肪酸酐,2.0 g脂肪族缩水甘油醚环氧树脂及0.5 g聚丙二醇,材料断裂伸长率可达231.65%,拉伸强度2.14 MPa。
The epoxy asphalt materials were prepared of heavy traffic 70# asphalt, polypropylene glycol, aliphatic glycidyl ether epoxy resin, aromatic anhydride and dimerized fatty acid anhydride （5 factors） and E -51 epoxy res- in. The five -factors and four -level orthogonal experiment was designed using tensile strength and elongation at break as the major assessment indicators. The major factors such as asphalt, reactive compatibilizer and curing agent on the mechanical properties of epoxy asphalt were investigated and the optimized best recipe was as followed： 10. 0 g E -51 bisphenol A epoxy resin, 52. 0 g heavy traffic 70# asphalt, 1.5 g aromatic acid anhydride, 8.0 g dimerized fatty acid anhydride, 2. 0 g of aliphatic glycidyl ether epoxy resin and 0. 5 g polyethylene glycol. The e- longation at break of the material was up to 231.65% and tensile strength was 2. 14 MPa.
