Problems solved by technology

[0004] The existing solid tire composition makes the cost of producing solid tires low, and the prepared solid tires are of good quality, but because the tread of solid tires is wider and the bearing surface is wider, more air will be displaced and more tires will be pushed. The air mass of the solid tire makes the shock absorption ability of the solid tire poor. At the same time, because of the heavy weight and high hardness of the solid tire, the tire noise during the driving process of the solid tire is relatively large.

Abstract

The invention discloses a noise-reducing and shock-absorbing solid tire and a preparation method thereof. Noise-reducing and shock-absorbing solid tires include a tire liner and tread rubber located on the outer circumference of the tire liner; the tire liner includes the following components: waste rubber, vulcanized reclaimed rubber, zinc oxide, stearic acid, accelerators, adhesives , shock-absorbing material; tread rubber includes the following components: waste rubber, zinc oxide, stearic acid, anti-aging agent, anti-fogging agent, Coumarone, noise-reducing material; the mass ratio of shock-absorbing material is 1:0.6‑0.9 : 0.3‑0.6 polyamide thermoplastic elastomer, SEBS thermoplastic elastomer and EPDM rubber; noise reduction materials include the following components: glass fiber, silicon carbide fiber, activated carbon fiber, expanded perlite, attapulgite and Acrylate emulsion; the noise-reducing and shock-absorbing solid tire of the present invention has an excellent shock-absorbing and noise-reducing effect, reduces the bumpy feeling and noise in the process of uneven ground formation, and enhances the advantages of user comfort.

Description

technical field [0001] The invention relates to the technical field of solid tires, in particular to a noise-reducing and shock-absorbing solid tire and a preparation method thereof. Background technique [0002] As we all know, solid tires have bearing capacity and cushioning capacity, and are widely used in vehicles such as large forklift trucks, engineering vehicles, and agricultural machinery. However, solid tires are generally made of rubber materials such as natural rubber or styrene-butadiene rubber. Since such tires are generally used under greater friction, the service life is short and problems such as cracking are prone to occur. On the other hand, with the soaring price of crude oil, 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 Southeast Asia and other countries. During the production of tires and conveyor belts, a large amount of leftover...
