A comparison of the initial 190 ℃ melt index and the initial YI value for each antioxidant composition of the examples and comparative examples is shown in fig. 1. In the upper graph, the abscissa indicates the MFI value of the melt index, and the ordinate indicates Huang Zhi YI value.

TABLE 2
From the above data, the samples of the blank and 1425+168 groups were waxy after 120 hours. In addition, the 1076+ pentaerythritol, 1076+ gms90,1076+ dpe,1076+ tpe antioxidant compositions corresponding to examples 1 to 4 showed the best color protection to polypropylene and the lowest YI after 120 hours.
TABLE 3 Table 3
As a judgment index of melt stability, the change condition of melt index after 48 hours (the melt index is normally reduced because the peroxide is partially crosslinked in the first 48 hours), and the experimental results show that in comparative examples 2,4, 5, 9 and 11, particularly in comparative example 2, when 1425+168 is used as an antioxidant, the polypropylene melt is waxy after 120 hours, and the antioxidant capacity is insufficient. The melt index of the remaining experimental groups remained relatively stable at 48 hours. The antioxidant composition provided by the embodiment of the invention is applied to polypropylene melt, and the melt index change is small after 48 hours.
Taken together, the above data indicate that the antioxidant compositions of examples 1-4 perform best in combination with respect to initial color, initial melt index, color protection, and melt index stability after application to polypropylene resins.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art.
