TABLE 1
As can be seen from Table 1, the tributyl citrate can be compounded and modified by adding the maleic anhydride and the amino silicone oil, so that the mechanical property and the heat resistance of the plasticizer can be improved. The maleic anhydride added in the embodiment of the invention can be subjected to acylation reaction with amino silicone oil to obtain siloxane containing carboxyl, and then tributyl citrate can be modified through the siloxane containing carboxyl, so that the carboxyl in the siloxane containing carboxyl reacts with hydroxyl of the tributyl citrate to introduce a high-functional siloxane bond and a flexible group, and the mechanical property and the heat resistance of the plasticizer can be improved.
In addition, the embodiment of the invention can generate a synergistic effect by adding the castor oil and the soybean oil so as to further improve the mechanical property and the heat resistance of the plasticizer.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
