As can be seen from Table 5, the mixed acid, mixed alkali, brine, mixed solvent, and thermal shock cycle resistance and high temperature and high pressure resistance of the coatings obtained in the examples are better than those of comparative examples 1 and 2. The examples 1 and 2 are slightly foamed after resisting the medium 120d, the paint film is intact after resisting the inorganic medium 120d in the examples 3-20, and more foams are generated after resisting the inorganic medium 120d in the comparison examples 1 and 2; the paint film is good after the hot and cold shock resistant cycle of the examples 1 and 2 is carried out for 30 times and the high temperature and high pressure resistant cycle of the examples 7d, the paint film is good after the hot and cold shock resistant cycle of the examples 3-20 and the high temperature and high pressure resistant cycle of the examples 7d, and more foams after the hot and cold shock resistant cycle of the examples 1 and 2 is carried out for 30 times and the high temperature and high pressure resistant cycle of the examples 7 d.
As can be seen from tables 4 and 5, the physical mechanical properties and the medium resistance of examples 7, 8, 19 and 20 are better, particularly the performances of examples 8 and 19 are optimal, so that the catalytic effect of the quaternary ammonium salt modified montmorillonite on the system is most obvious, particularly the long-carbon-chain quaternary ammonium salt modified montmorillonite catalytic system generates higher crosslinking density, and the physical mechanical strength and the medium resistance of the system are remarkably improved. As can be seen from comparative examples 8 and 19, the addition of the metal salt is beneficial to the crosslinking of the catalytic system, so that the system generates higher crosslinking density, and the physical mechanical strength and the medium resistance of the system are obviously improved. The comparison of the adhesion of the embodiment and the comparative sample shows that the addition of the modified montmorillonite greatly reduces the cohesion of the system, so that the adhesion of the coating on the steel substrate and the concrete substrate is greatly improved, and the adhesion is improved to 15MPa from 5-6 MPa.
As shown in Table 6, the aqueous nano heavy-duty anticorrosive coating is environment-friendly and pollution-free in the construction process and the paint film drying process, the thickness of the construction coating is low, the construction method is convenient and fast, the selectivity is high, the construction scheme can be changed according to actual conditions, and the construction performance of the coating is superior to that of polyurea elastomers and epoxy glass fiber reinforced plastics.
