Embodiment Construction
[0016] The invention provides a modification method for improving the shape memory performance of eucommia gum, and the specific implementation steps are as follows:
[0017] (1) Start the Brabender plasticizing internal mixer, and preheat it for 2 minutes, preheat the temperature of the feeding port and the mixing head to 70°C, and set the roller shaft speed to 50r / min;
[0018] (2) Add a certain amount of bulk Eucommia gum in batches, after the Eucommia gum is heated and softened and mixed evenly, add a certain amount of zinc oxide powder, stearic acid and anti-aging agent 4010NA, and knead at 70°C for 7 minutes;
[0019] (3) Add a certain amount of N-cyclohexyl-2-benzothiazole sulfenamide and different amounts of dibenzoyl peroxide into the Brabender plasticizing internal mixer, and set the roller shaft speed to 80r / min, mixing for 15min;
[0020] (4) Peel off the eucommia gum after the full reaction, place it on a molding machine, set the temperature at 160°C, the pressu...
