Title:
POLYURETHANE PNEUMATIC TIRE AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2021/036327
Kind Code:
A1
Abstract:
Disclosed are a polyurethane pneumatic tire and a method for manufacturing same. The tire comprises a polyurethane tread (1), a polyurethane belt ply (3), a polyurethane tire sidewall (4), a polyurethane tire body (8), a polyurethane soft bead filler (5), a polyurethane stiff bead filler (6), a steel bead wire (7) and a seam abrasion-resistant filler (9) which are sequentially arranged from outside to inside. A polyurethane material is used to replace a rubber material, such that the tire performance is excellent, and the service life is greatly prolonged. Meanwhile, compared with a natural rubber material, the polyurethane material has a more comprehensive performance, and the polyurethane pneumatic tire is simpler in structure compared with a rubber tire.
