▎ 摘　　要

NOVELTY - Lightweight wear-resistant puncture-resistant automatic leakage-stopping five-layer polyurethane rim inner tube comprises 5-10 wt.% high-strength modified powder graphene added to the outermost layer, and then blended with TPU, and granulated by blending and granulation, 95-98 wt% TPU and 3-5 wt%. water. The water-absorbing resin is added to a second layer and a third layer, mixed and stirred. The fourth layer and the fifth layer are 100-100 wt of TPU. The opening agent is used for mixing and stirring. USE - Light weight wear-resistant puncture-resistant automatic leakage-stopping five-layer polyurethane rim inner tube for tire. ADVANTAGE - The light weight wear-resistant puncture-resistant automatic leakage-stopping five-layer polyurethane rim inner tube has excellent wear resistance, wear resistance and automatic plugging property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a forming technique of light weight wear-resistant puncture-resistant automatic leakage-stopping five-layer polyurethane rim tire.
