Embodiment 1
[0020] The formula of TPU particles is shown in Table 1:
[0021] Table 1
[0022]
[0023] (1) Fully mix the macromolecular glycol, antioxidant, lubricant, light stabilizer, and organotin catalyst according to the mass ratio, and heat to 120°C;
[0024] (2) Heating the diisocyanate to 60°C in another reaction kettle;
[0025] (3) Heat the chain extender to 60°C; inject the three components into the sprue of the twin-screw extruder according to the above-mentioned mass ratio setting flow rate, fully mix and completely react in the twin-screw extruder, and set the screw temperature to 130-240°C;
[0026] (4) Organic montmorillonite nanoparticles are added to the material at the twin-screw exhaust port through a side feeder, and are evenly mixed with the material in the screw;
[0027] (5) Cut the particles under water and dry at 80-110°C to obtain TPU particles with a Shore hardness of 75D;
[0028] (6) Take 60 parts of dried TPU particles and 10 parts of compatibilizer,...
