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 power vehicle (bicycle, tricycle, cart, driving car) tire

Abstract

The present invention belongs to a hand cart type with high elastic force and its preparation method. It is technically characterized by that it is made up by using tyre surface and tyre core, utilizing vulcanization mould and adopting thermo-bonding and fixedly connecting process, and the tyre surface and tyre core are made up by using various auxiliary materials prepared with natural rubber trough the processes of plastication, mixing, finely-mixing warming glue and rubber rod forming. Said invention hand cart type can be used as a substitute for inflation-free tyre.

Description

[0001] Field [0002] The invention belongs to the field of tires, in particular to a high-elasticity vehicle tire and a preparation method thereof. Background technique [0003] In view of the fact that pneumatic tires have various defects such as fear of puncture, air leakage, and bursting, non-inflatable tires have emerged as the times require. 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 power vehicle (bicycle, tricycle, handcart, driving car) tire. Contents of the invention [0004] The purpose of the present invention is to overcome the de...
