Performance testing
Test results, test methods are given in Table 1 below
TABLE 1
Through the tests, the compound use of the trihydric alcohol and the dihydric alcohol is found, and meanwhile, under the action of the maleic anhydride, the tetrahydrophthalic anhydride and preferably the air-drying monomer trimethylolpropane diallyl ether, the better flexibility and adhesive force can be shown, and the application performance on high-speed rails is improved.
More specifically, the linoleic acid has air-drying property, and the trimethylolpropane diallyl ether also has air-drying property, and the combination of the linoleic acid and the trimethylolpropane diallyl ether can improve the air-drying speed, the coating flexibility and the adhesion of the whole formula.
Linoleic acid is polyunsaturated fatty acid, and can improve the shock resistance by being matched with the myristic acid, which is a saturated fatty acid.
The contribution of phthalic acid to impact resistance is limited and the improvement in the overall performance of terephthalic acid is detrimental.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof.
