From the test results of table 1 above, it is clear that the color road surface protective agents prepared in examples 1 to 9 have good compressive strength, toughness, slip resistance, wear resistance, and long-lasting color freshness after curing, and good low temperature resistance. From the comparison between examples 1 to 3, the product of example 1 was more excellent in performance, and the difference in the internal proportions of the A component and the B component was a difference in the color road surface protective agent. From a comparison of examples 1 and examples 4 to 5, it is understood that the products of examples 4 to 5 have higher compressive strength, and the difference is that the types of curing agents used in the products of examples 4 to 5 are different from those of example 1.

Comparative example 1 has significantly reduced test performance compared to example 1 in the absence of the starting material methyl 3- (4-benzonitrile) acrylate.
Comparative example 2 shows a significant decrease in various test properties compared to example 1 in the absence of the starting methoxypolyethylene glycol-enoate.
