Steel materials are widely used in marine environments as the most commonly used building materials. However, since the marine environment has high salinity and high humidity, the corrosion is one of the most severe natural environments, and therefore, the corrosion and protection of steel materials in the marine environment are important problems which plague the development activities of the human ocean.
At present, in the marine atmosphere environment, the conventional protection means are generally coating layers, margarine and other protection means, but long-term practice shows that the conventional means cannot provide good protection due to the high corrosiveness of the marine atmosphere, so that the anti-corrosion paste material applied to the marine atmosphere environment has been developed, and the corrosion resistance is improved to a certain extent compared with the coating layers and margarine technology, but the anti-corrosion paste material is still far from adequate protection to the severe marine atmosphere environment. Therefore, in view of the above problems, there is an urgent need for a polymer anticorrosive paste having high corrosion resistance and rust conversion properties.

TABLE 1
As shown in Table 1, the epoxy modified high-temperature petrolatum anticorrosion paste has comprehensive performance improving effect by additionally introducing raw materials such as polyisobutene, epoxy resin, the proportion of each component of the modifier, N, N, N ', N' -tetra (2-hydroxyethyl) adipamide and the like. Through analysis, the epoxy resin possibly participates in the restraint of intermolecular van der Waals force in the petrolatum corrosion inhibitor, and simultaneously acts together with N, N, N ', N' -tetra (2-hydroxyethyl) adipamide to improve the crosslinking density, so that the contact angle is increased, and the corrosion phenomenon can be reduced by using petrolatum.
The invention and its embodiments have been described above by way of illustration and not limitation, and the actual construction is not limited to this. Therefore, if one of ordinary skill in the art is informed by this disclosure, the structural mode and the embodiments similar to the technical scheme are not creatively designed without departing from the gist of the present invention.
