一、引言环氧沥青漆广泛应用于金属保护。这种配方适于做船底漆、管道漆和各种贮罐涂料以及适于做一般的维修漆。这是由于这种涂料具有良好的机械性能和极好的水下耐久性的缘故。事实上,不管聚合物基体上有多少数量的亲水环氧基团,疏水煤焦沥青的存在就能减少水的吸附和渗透,因而提高了漆膜的保护性能。另一方面,这些漆膜的环境老化,在很大程度上取决于由这种配方的不均匀组成而引起的树脂交联程度。溶剂、增塑剂和低分子量 First, the introduction Epoxy asphalt paint is widely used in metal protection. This formulation is suitable for boat primer, pipe paint and various tank coatings as well as for general maintenance paint. This is due to the good mechanical properties and excellent underwater durability of this coating. In fact, the presence of hydrophobic coal tar pitch reduces water adsorption and penetration regardless of the amount of hydrophilic epoxy groups present on the polymer matrix, thereby increasing the protective properties of the film. On the other hand, the environmental degradation of these films depends to a large extent on the degree of crosslinking of the resin caused by the inhomogeneous composition of this formulation.
