Embodiment 1
[0029] Preparation of corn husk reinforced polypropylene composites
[0030] (1) Place about 10 grams of polypropylene resin particles between two layers of polyimide film. Then they were placed on a flat vulcanizer, and the parameters of the flat vulcanizer were set as follows: temperature 200° C., pressure 5 MPa, action time 100 seconds. Preheat for 60 seconds first, then heat press for 40 seconds. After hot pressing, it is cooled at room temperature under the action of 2MPa. A polypropylene resin film with a thickness of about 0.1 mm was obtained.
[0031] (2) After cleaning and sorting the corn husks just peeled off from the corn, bake them in an oven at 60°C for 8 hours. Then cut off its head and tail, and flatten it under the action of 0.1MPa.
[0032] (3) Lay the PP film and the corn husks alternately, fix them with a mold and place them between two layers of polyimide films with a thickness of 1 mm and a length and width of 30 cm, which are resistant to high temper...

[0034] Preparation of corn husk reinforced polylactic acid resin composites
[0035] (1) Place 10g of polylactic acid resin particles between two layers of polyimide film. Then they were placed on a flat vulcanizer, and the parameters of the flat vulcanizer were set as follows: temperature 200° C., pressure 5 MPa, action time 100 seconds. Preheat for 60 seconds first, then heat press for 40 seconds. After hot pressing, it is cooled at room temperature under the action of 2 MPa. A polylactic acid resin film with a thickness of about 0.1 mm was obtained.
[0036] (2) After cleaning and sorting the corn husks just peeled off from the corn, bake them in an oven at 60°C for 8 hours. Then its head and tail were cut off, and it was flattened under the action of 0.1 gram.
[0037] (3) Lay the PLA film and the corn husk alternately on top of each other, fix them with a mold, and place them between two layers of polyimide films with a thickness of 1 mm and a length and width of 30 c...

[0039] Preparation of polybutylene succinate composite material reinforced with corn husk
[0040] (1) 10 g of polybutylene succinate resin particles were placed between two layers of polyimide films. Then they were placed on a flat vulcanizer, and the parameters of the flat vulcanizer were set as follows: temperature 130° C., pressure 5 MPa, action time 100 seconds. Preheat for 60 seconds first, then heat press for 40 seconds. After hot pressing, it is cooled at room temperature under the action of 2 MPa. A polybutylene succinate resin film with a thickness of about 0.1 mm was obtained.
[0041] (2) After cleaning and sorting the corn husks just peeled off from the corn, bake them in an oven at 60°C for 8 hours. Then cut off its head and tail, and flatten it under the action of 0.1MPa.
[0042] (3) Lay the PBS film and the corn bracts in alternate layers, fix them with a mold, and place them between two layers of polyimide films with a thickness of 1 mm and a length and w...
