Background
At present, the petrolatum-coated corrosion protection technology has developed relatively mature, and the basic structure of the technology is composed of 3 layers, namely petrolatum corrosion protection paste (also called primer), a corrosion protection belt and an outer layer protection cover (also called armor), wherein the outer layer protection cover has various forms, such as a high-density polyethylene armor, a polyethylene foam composite glass fiber reinforced plastic or a reinforced glass fiber reinforced plastic anticorrosion cover and the like. The petrolatum anti-corrosion paste is one of core materials of the coating technology, is positioned at the innermost layer, and is directly and tightly contacted with a protected metal matrix to form a protective sealing layer.
In the use process of the petrolatum coating technology, particularly under the condition of direct sunlight outdoors in summer, the phenomenon of oil leakage often occurs, namely the phenomenon of oil stain or oil dripping occurs on the outer protective cover, which is caused by the separation and seepage phenomenon of low molecular oil components in the petrolatum anticorrosion paste at a higher temperature for a long time.
