And (3) performance testing:
the coatings of examples 4 to 6 and comparative examples 1 to 6 were formed into coating films according to the national Standard "GB/T1727 general paint film preparation method", and the coating films formed from the coatings of examples 4 to 6 and comparative examples 1 to 6 were subjected to the performance test using the following standards, and the test results are shown in Table 1.
Wear resistance: the measurement is carried out by referring to a rotating rubber grinding wheel method for measuring the abrasion resistance of GB/T1768-2006 color paint and varnish.
Moisture and heat resistance: the determination is carried out by referring to the humidity and heat resistance determination method of GB/T1740-2007 paint film.
Alkali resistance: the determination is carried out by referring to a GB/T1763-1979 paint film chemical reagent resistance determination method.
Ultraviolet resistance: the determination is made with reference to the weathering exposure of GB/T23987-.
TABLE 1 results of the performance test of the coating films obtained in examples 4 to 6 and comparative examples 1 to 6.
As can be seen from table 1, the weather-resistant self-repairing coating prepared in examples 4 to 6 has a stimulus responsiveness and a slow release performance to pH, when the pH of the corrosion inhibitor molecule is greater than 8, the corrosion inhibitor molecule is automatically released from the coated polymer, migrates the surface of the coating, realizes the controllable release of the corrosion inhibitor, and the released corrosion inhibitor is adsorbed to the surface of the substrate to form a film, so as to generate protection, so that the slow release effect has responsiveness, and the corrosion prevention time of the coating is greatly delayed; when the coating is not corroded, the polymer does not release the corrosion inhibitor, so that the long-term use of the corrosion inhibitor is ensured. In addition, the resin containing the crosslinked network structure in the coating film improves the weather resistance, wear resistance and wet and heat resistance of the coating. Comparative example 1 the coating made of the ordinary polypropylene resin has no stimulation responsiveness and slow release performance to pH, has poor compatibility with the corrosion inhibitor, and the prepared coating film has poor weather resistance, wear resistance and humidity resistance. Comparative example 2 the coating material made of the resin containing no pyridyl group had no stimulus response to pH, and the resin could not form a coordinate bond with the corrosion inhibitor, and the weather resistance, wear resistance and wet heat resistance of the resulting coating film were reduced. Comparative example 3 the coating made of the resin without beta-cyclodextrin has no slow release effect on the corrosion inhibitor, and the resins can not form a cross-linked network structure, so that the weather resistance, wear resistance and damp-heat resistance of the prepared coating film are reduced. In comparative examples 4, 5 and 6, one of the corrosion inhibitors is absent, and the resulting coating films are reduced in weather resistance, abrasion resistance and wet heat resistance.
Finally, it should be noted that the above-mentioned embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same, and although the present invention is described in detail with reference to the above-mentioned embodiments, it should be understood by those skilled in the art that the modifications and equivalents of the specific embodiments of the present invention can be made by those skilled in the art after reading the present specification, but these modifications and variations do not depart from the scope of the claims of the present application.
