大型车辆要有坚固的防腐层。例如,全金属客车车体内表面现在使用213、580、579号高粘性沥青玛脂防护层,可确保防腐期达4年至8年。但在大多数情况下,当客车使用几年以后,就在1.5至2.0毫米厚的涂层下面发生腐蚀,而防腐层仍然状态良好。为了提高玛脂的保护和防水性能,本文提出了使用低溶解的阻蚀剂对沥青基进行改性处理。试验表 Large vehicles have a strong coating. For example, all-metal passenger car body surfaces now use 213,580,579 high-viscosity bitumen masonry to ensure a corrosion-resistant period of 4 to 8 years. In most cases, however, corrosion occurs below 1.5 to 2.0 mm thick coatings when the bus is used for several years, and the coating is still in good condition. In order to improve the protection and water-repellent performance of the mascara, this paper proposes to modify the asphalt-based using a low-solubility corrosion inhibitor. Test table
