Problems solved by technology

[0003] Due to fluctuations in the quality of natural rubber from different origins, problems such as belt sticking to rollers, skipping wires, and rough surface of the belt layer will occur during the calendering process of tire manufacturing. Although the survival can be maintained by reducing the calendering speed, the production efficiency is reduced. The quality of semi-finished products has declined

Abstract

The invention relates to a tire belt ply calendering process. The tire belt ply calendering process comprises the step of laminating rubber-rubbed steel wires by using a four-roller calender, whereinthe rubber supply temperature is 95-105 DEG C, the temperature of an upper roller of the four-roller calender is 60-70 DEG C, the temperature of a middle roller is 60-70 DEG C, the temperature of a side roller is 85-95 DEG C, the temperature of a lower roller is 85-95 DEG C, and the temperature of a belt ply is kept at 80 DEG C. The process provided by the invention overcomes the defects of the calendering process in the prior art, and provides the tire belt ply calendering process; and the calendered belt ply is uniform in thickness, smooth in surface and free from pleating, and the problem of roller sticking is solved. The production efficiency is increased by 50%.

Description

technical field [0001] The invention relates to a tire belt calendering process, which belongs to the technical field of tire production. Background technique [0002] Tires are circular elastic rubber products that are rolled on the ground and rolled on various vehicles or machinery. Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperature effects during driving, so they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, it is also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. Half of the world's rubber consumption is used for tire production, which shows the ability of tires to consume rubber. [0003] Due to fluctuations in the quality of natural rubber from different origins, problems such as belt sticking to rollers, skipping wires, and rough surface of ...
