Example 5
This example differs from example 4 in that during the aqueous gloss oil modification treatment, no polyvinylidene fluoride is added and the balance is made up with an ethylene/methyl acrylate/cycloalkenyl acrylate terpolymer.
Example 6
This example differs from example 4 in that during the aqueous gloss oil modification treatment no ethylene/methyl acrylate/cycloalkenyl acrylate terpolymer was added and the balance was made up with polyvinylidene fluoride.
Example 7
This example differs from example 4 in that the ethylene/methyl acrylate/cycloalkenyl acrylate terpolymer was replaced with the same amount of methyl acrylate.
Example 8
This example differs from example 4 in that the polyvinylidene fluoride is replaced by an equal amount of polytetrafluoroethylene.

Performance detection test method
The quality of the aluminum-plated drawn wires produced in examples 1 to 10 was evaluated, and the details are shown in the following table.
TABLE 1 quality evaluation Table
From table 1, the results of quality evaluation in examples 1 to 3 show that the aluminized cords produced in the present application have excellent overall properties, but the surface of the water-based varnish printed layer is sticky to some extent.
Combining the quality evaluation results of example 1 and example 4, the addition of the ethylene/methyl acrylate/cycloalkenyl acrylate terpolymer and the polyvinylidene fluoride can effectively improve the image-text clarity and effectively improve the problem of stickiness on the surface of the aqueous gloss oil printing layer. The reason for analyzing the method is probably that the addition of the ethylene/methyl acrylate/acrylic acid cycloalkenyl terpolymer and the polyvinylidene fluoride can effectively improve the alkali resistance of the water-based varnish printing layer, and the protection effect on the pictures and texts is better; meanwhile, oxygen can be effectively combined, and the bad phenomenon that the surface of the aqueous gloss oil printing layer is sticky due to the contact of the surface of the aqueous gloss oil printing layer and the oxygen is reduced. From the quality evaluation results, the ethylene/methyl acrylate/cycloalkenyl acrylate terpolymer and the polyvinylidene fluoride have a certain degree of synergistic coordination relationship.
And the practical effect is better when the ethylene/methyl acrylate/acrylic acid cycloalkenyl terpolymer and the polyvinylidene fluoride are modified by the titanate coupling agent in advance according to the quality evaluation result of the embodiment 9.
The specific embodiments are only for explaining the present application and are not limiting to the present application, and those skilled in the art can make modifications to the embodiments without inventive contribution as required after reading the present specification, but all the embodiments are protected by patent law within the scope of the claims of the present application.
