Embodiment 1
[0019] The preparation method of above-mentioned aircraft tire comprises the following steps:
[0020] Step 1, prepare the crown layer: add 40 parts by weight of natural rubber and 10 parts by weight of natural Eucommia gum to the open mill, and after masticating for 2 minutes to 4 minutes at 55 ° C ~ 65 ° C, add 5 parts by weight of graphene , continue to knead for 2min~5min and then release the glue, extrude it through a calender, place it on a nylon mesh, and cut it at equal intervals to obtain a number of crown layers with an axial width of L1 for use;
[0021] Step 2, prepare tire teeth: Prepare steel cables by winding several steel wires, bend the steel cables into rings, heat the ring-shaped steel cables, wrap molten rubber on the surface of the ring-shaped steel cables, cool and cut them to obtain The cross-section is fan-shaped fetal teeth.
[0022] Step 3, preparing the fetal capsule: send the mixed rubber containing 50 parts by weight of natural rubber and 40 parts...
Embodiment 2
[0031] In step 1, natural rubber is 20 parts by weight, and natural eucommia gum is 20 parts by weight, and graphene is 10 parts by weight; in step 3, natural rubber is 75 parts by weight, and natural eucommia gum is 20 parts by weight; in step 4, natural rubber is 50 parts by weight Parts by weight, natural eucommia gum is 40 parts by weight, DZ is 0.5 parts by weight, 4010NA is 10 parts by weight, graphene 10 parts by weight, sulfur 2 parts by weight; natural rubber is 50 parts by weight in step 5, and natural eucommia gum is 40 parts by weight part, DZ is 0.5 parts by weight, 4010NA is 4 parts by weight, Graphene 10 parts by weight, sulfur 2 parts by weight; all the other conditions are the same as embodiment 1.
[0032] The order of steps 1 to 5 in the above examples can be freely reversed, and the ratio of ingredients in each step is limited to the corresponding step, not relative to the amount of ingredients in other steps.
