Embodiment 1

[0022] In the present embodiment, the method for preventing carcass ply cracks during the formation of radial aviation tires specifically includes the following steps:

[0023] First, the vulcanization characteristics are similar to those of the inner layer of radial aviation tires. The Shore A hardness is 65 degrees. After being heated on the tablet press, a film with a width of 50 mm and a thickness of 0.6 mm is extruded.

[0024] Second, when fitting the tire carcass cord, cut the film made by the above method into a length of 400mm, and the specific length depends on the size of the tire and the width of the cord.

[0025] Third, stick the film under the joint of the second layer of cord, and between the first layer of cord and the second layer of cord, symmetrically fit, and the joint is in the middle of the film; both sides of the film are as wide as the edge of the cord. Tape under each second ply ply joint.

[0026] Fourth, the implemented radial aircraft tire carcass...

Abstract

The invention discloses a method for preventing carcass ply cracks during the molding of radial aviation tires, and relates to the technical field of radial aviation tires. , a film with a thickness of 0.5-1mm; Step 2, cut the length of the film in Step 1 to 200-700mm, and prepare to fit the tire carcass cord; Step 3, Lay the film in Step 2 symmetrically on the tire Under the joints of the inner carcass ply except the first layer; the bonding position is that the two sides of the film are the same width from the edge of the ply; Step 4, the film is tightly adhered to remove air bubbles. The method for preventing carcass ply cracks during the molding of radial aviation tires provided by the invention improves the qualified rate of products, improves the quality of radial aviation tires, and ensures the use strength and airtightness thereof.

Description

technical field [0001] The present invention relates to the technical field of radial aviation tires, in particular to a method for preventing carcass ply cracks during forming of radial aviation tires. Background technique [0002] Compared with the biased aviation tire, the radial aviation tire can achieve greater load capacity, higher take-off speed and lighter weight design. Therefore, the radial design of aviation tires has become the development trend of modern aviation tire technology. In recent years, the demand and output of radial aviation tires have been on the rise. [0003] With the increase of production volume, various quality problems have arisen in the production process of radial aviation tires. Among them, the quality problem of carcass ply cracks during the formation of radial aviation tires is more prominent. Analysis of the causes of the cracks in the carcass cord: 1. When the radial aircraft tire carcass is formed, it is necessary to inflate the tire...
