Aramid fiber composite material, composite material for preparing solid tyre and manufacturing methods of two

Abstract

The invention discloses an aramid fiber composite material solid tyre, a tread rubber layer composite material for preparing the solid tyre, a tread base rubber composite material and manufacturing methods of the tyre-surface rubber-layer composite material and the tread base rubber composite material. The solid tyre comprises a tread layer, a buffer layer, a tread base layer and a tyre internal steel ring; the tread layer is attached to the buffer layer, the buffer layer is attached to the tread base layer, and the tyre internal steel ring is embedded in the tread base layer; and the tread layer employs the tread rubber layer composite material, and the tread base layer employs the tread base rubber composite material. Aramid fiber possesses characteristics of high strength, good wear resistance, good temperature resistance and impact resistance, basalt fiber possesses high-temperature resistance characteristic, rubber possesses extremely good buffering performances, the above three materials are combined and the characteristics of the three materials are provided, and the solid tyre prepared from the composite material can be used on a high-temperature pavement or tropical region for a long time, is guaranteed to be uneasy to age, and is prolonged in service life.

Description

technical field [0001] The invention relates to a solid tire made of aramid fiber composite material and a preparation method thereof, in particular to a solid tire made of aramid fiber composite material used for transport vehicles such as forklifts and loading and unloading machines, and a tread rubber layer composite material for making solid tires , Tire base rubber composite material and manufacturing method thereof. Background technique [0002] With the rapid development of global logistics, construction machinery and mining machinery, higher requirements are placed on the quality of solid tires. High-performance tire products with high wear resistance and fatigue life have become a hot spot in the industrialization of tire products. On the other hand, under the current background of energy conservation and emission reduction, such as the logistics industry, construction machinery, and mining machinery, the use of solid tires is huge. Improving the service life of sol...

AI Technical Summary

Problems solved by technology

However, solid tires are generally made of natural rubber and styrene-butadiene rubber. Since such tires are generally used in a relatively large friction environment, their service life is short, and they are prone to heating, puncture, cracking, and fast wear. question

On the other hand, with the increase of crude oil price, the price of synthetic rubber has also risen further, and there is still a large gap in natural rubber in my country, which needs to be imported in large quantities from abroad.

Tires and conveyor belts produce a lot of leftovers in the production process and have not been well utilized
