Abstract
The invention belongs to the technical field of metal surface treatment, and discloses a magnesium alloy sealing reinforcing agent and a sealing reinforcing treatment process, wherein the magnesium alloy sealing reinforcing agent comprises the following components: 1-50 g/L of fatty acid, 2-100 g/L of alcohol, 5-100 g/L of organic amine, 0.1-5 g/L of complexing agent, 0.5-10 g/L of inorganic base and 0.2-10 g/L of vanadium salt. Under the synergistic effect of the components, the corrosion resistance of the magnesium alloy workpiece, the resistance stability of the surface of the magnesium alloy workpiece and the adhesion stability of the coating or auxiliary materials on the surface of the magnesium alloy can be obviously enhanced after the magnesium alloy workpiece is treated by the sealing reinforcing agent.
Description
Technical Field
The invention relates to the technical field of metal surface treatment, in particular to a magnesium alloy sealing reinforcing agent and a sealing reinforcing treatment process.

TABLE 1 Effect of various treatment groups on the Performance of magnesium alloy conversion coatings
As can be seen from the test results in Table 1, the experimental results: in the same salt spray (24h) test conditions, the combined effects of the salt spray corrosion resistance effect, the surface white point, the surface resistance after salt spray, the 36# dyne pen test and the paint adhesion stability test of example 1 are the best, and are the best example 1 of the present invention; examples 2-5 formula proportions and treatment parameters of the magnesium alloy reinforcing treatment agent are correspondingly adjusted compared with example 1, and it is found that a few white spots or salt spray corrosion resistance is slightly reduced after salt spray, surface resistance and dyne test are not changed greatly, and coating adhesion stability is not changed greatly; comparative example 1 is a blank comparative item which is not treated by a sealing reinforcing agent, salt spray corrosion resistance effect is passed, but a large number of white dots are generated on the surface of a workpiece after salt spray, the surface resistance of the workpiece after salt spray is unstable, most of the dots are larger than 5 omega, the white dot part resistance is larger, and the 36# before salt spray begins to diffuse after 10s of pen test, which shows that after the magnesium alloy sealing reinforcing agent is carried out, various physical properties of the magnesium alloy workpiece can be obviously enhanced; the comparative example 2 shows that the sealing reinforcing agent is not added with vanadium salt, the salt mist corrosion resistant effect of the sealing reinforcing agent is passed, the surface of a workpiece generates more white spots after salt mist, the surface resistance of the workpiece is unstable, most spots are larger than 5 omega, the resistance of white spot parts is larger, and 36# dyne pen tests and paint adhesion stability tests pass, which indicate that the sealing reinforcing agent for the magnesium alloy disclosed by the invention is a multi-component synergistic effect, and particularly, the salt mist resistance and the resistance stability of the surface of the magnesium alloy workpiece can be further enhanced by the mutual matching of the vanadium salt and the fatty acid.
As can be seen from fig. 1, fig. 1A, 1B, 1C, and 1D are the appearance images of the magnesium alloy workpieces of example 1, example 2, example 3, and comparative example 1 after 24h salt spray test, respectively, and it is apparent that comparative example 1 without the magnesium alloy strengthening treatment process generates a large number of white spots.

The surface tension is large due to the fact that the pen test scratches appear in 10s and are diffused or shrunk, the adhesive effect of the auxiliary materials is influenced, and the auxiliary materials are not firm to adhere and are easy to warp edges or fall off; the scratch 10s is unchanged in the pen test, so that the surface tension is small, and the auxiliary materials are firmly adhered and are not easy to fall off.
As can be seen from fig. 4, fig. 4A and 4B are the effects of surface white spots of comparative example 2 and example 1 after the 12-h salt spray test, respectively, and it is clearly seen that example 1 has no white spots, while comparative example 2 has a small amount of white spots.
As can be seen from fig. 5, fig. 5A and 5B show the effect of surface white spots (using another magnesium alloy workpiece) after 24h salt spray test of example 1 and comparative example 1, respectively, and it is obvious that the surface of example 1 is uniform and has no white spots, while the surface of the un-nucleated reduced workpiece of comparative example 1 is significantly mottled and has more white spots.
As can be seen from fig. 6, fig. 6A and 6B respectively show the paint adhesion test effects of comparative example 1 and example 1, and it is obvious that the paint-dropping phenomenon does not occur when the magnesium alloy paint of example 1 is sprayed after the sealing and reinforcing treatment, and the paint-dropping phenomenon occurs to different degrees at the edge of the test knife-edge after the magnesium alloy paint of comparative example 1 is sprayed.
The above embodiments are the best mode for carrying out the present invention, but the embodiments of the present invention are not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be regarded as equivalent substitutions and are included in the scope of the present invention.
