Problems solved by technology

But this technology has the following disadvantages: 1. As a means of transportation, especially shared bicycles, the general riding speed is about 8-12 km / h, and the speed of electric bicycles will reach 25 km / h, or even higher , while mopeds and electric tricycles can reach a speed of 50 km / h
Therefore, the material produced by this technology cannot meet the requirements of electric vehicle tire compression deformation
[0006] In order to develop tire materials with better quality, whether it is pneumatic or non-pneumatic tire materials, R&D personnel have conducted a lot of research. At present, domestic tire materials still have complex production processes, low fatigue resistance, poor wear resistance, and recycling. Therefore, it is urgent to provide a tire material with simple production method, wear resistance, weather resistance, high toughness, high elasticity and long service life and its preparation method.
