Embodiment 1
[0019] The specific preparation process of the antioxidant is as follows: ①Add 10g of mercaptosuccinic acid into 100mL of water and stir to dissolve, then add 16.7g of thionyl chloride solution to it, raise the temperature to 70-80°C for reflux reaction for 10-12h, and then dissolve the obtained product The solution was evaporated at 90°C. At this time, the unreacted thionyl chloride solution decomposed, and the solvent water evaporated at the same time to obtain mercaptosuccinyl chloride; ②Add 1.68g of mercaptosuccinyl chloride prepared in step ① and 50mL of water into the reaction vessel, stir to dissolve , and then add 2.88g of 1-piperidinethiocarbonylamine to it, raise the temperature to 60-65°C for reflux reaction for 15-16h, and then obtain the antioxidant through vacuum distillation.
Embodiment 2
[0021] The high-strength hydrophobic film is made by adding high-density polyethylene, low-density polyethylene, the antioxidant, dispersant, and surfactant prepared in Example 1 according to the mass ratio of 100:12.3:0.73:2.16:0.86 after extrusion Casting to obtain a high-strength hydrophobic film.
Embodiment 3
[0023] The preparation method of the high-strength hydrophobic film is the same as in Example 2, and the antioxidant prepared in Example 1 used in Example 2 is replaced by 1-piperidinethiocarbonylamine.
