Experiment 1
The abrasion resistance of the test specimen prepared from the abrasion resistant coating for labels of each example and comparative example was measured according to GB/T1768-2006 method for measuring abrasion resistance of colored paint and varnish by rotary rubber grinding wheel. The number of revolutions for the abrasion test was 30000 revolutions.
The preparation method of the sample to be tested comprises the following steps:
And (3) smearing the wear-resistant coating for the label on a plastic plate, baking for 10min at 125 ℃, and curing and forming to obtain a sample to be tested.

TABLE 1
| Mass fray (mg) | |
| Example 1 | 76 |
| Example 2 | 71 |
| Example 3 | 73 |
| Example 4 | 98 |
| Comparative example 1 | 156 |
| Comparative example 2 | 151 |

| Comparative example 4 | 147 |
| Comparative example 5 | 166 |
According to the comparison of the data in the table 1, the wear-resistant coating for the label prepared by each embodiment has significantly higher wear resistance after curing than that of each comparative example, and it can be seen that by adding the composite additive compounded by ammonium polyphosphate, fatty alcohol-polyoxyethylene ether, calcium superphosphate and sodium tetraborate into the coating, each embodiment can achieve good modification effect under the mutual coordination of ammonium polyphosphate, fatty alcohol-polyoxyethylene ether, calcium superphosphate and sodium tetraborate, so that the wear resistance of the coating after curing is significantly improved.
While each comparative example is added with an auxiliary agent for improving the wear resistance of the coating after curing, the effect of mutually coordinated and matched components in the composite auxiliary agent in the examples is lacking, so that the effect of improving the wear resistance of the aqueous acrylic emulsion is far less than that of each example.
The wear resistance of the coating of examples 1-3 after curing is higher than that of example 4, and it can be seen that the xenon is introduced in the process of preparing the wear-resistant coating for the label to play a certain role in catalysis, so that the modification effect of the composite additive on the aqueous acrylic emulsion is better, and the wear resistance of the coating after curing is further improved.
