AI Technical Summary

Problems solved by technology

At present, the air-free tires on the market are solid tires, that is, the whole tire is directly made of the same material regardless of the tread and the heart. However, problems such as heavy volume, low elasticity, and high power consumption have been difficult to overcome, and the material of this type of solid tire is mainly made of recycled rubber, and the indicators such as wear resistance, cushioning, and aging resistance cannot meet market needs. It is necessary for tires of tool carts or other vehicles (bicycles, tricycles, handcarts, running cars)

Abstract

A high-elasticity tyre and its manufacture are disclosed. The tyre is characterized by heat seal fixed connecting tread with fetal from vulcanizing mould, plastic smelting from natural rubber auxiliary materials, mixed smelting, fining smelting, warm gluing and adhesive bar shaping. Its advantages include less weight, good elasticity, better vibration-resistant, shock-proof, loading, buffering and abrasive-resistance performances.

Description

[0001] Field [0002] The invention belongs to the field of tires, in particular to a high-elasticity tire and a preparation method. Background technique [0003] In view of the fact that pneumatic tires have various defects such as fear of sticking, air leakage, bursting, etc., air-free tires have emerged. At present, the non-pneumatic tires on the market are solid tires, that is, the entire tire is directly made of the same material regardless of its tread and tire core. Although it overcomes some of the defects of pneumatic tires, this type of tire is solid. However, there are problems that are difficult to overcome, such as heavy volume, low elasticity, and high power consumption. The material of this type of solid tire is mainly made of recycled rubber, and the indicators of wear resistance, cushioning, and aging resistance cannot meet the needs of the market, especially It is the need for tires of tool carts or other vehicles (bicycles, tricycles, trolleys, and mobile carts)....
