Method for preventing aerotyre of small dimension generating naked wire at aerotyre sidewall

Abstract

The invention discloses a method which prevents an exposed stitching of the side wall of an aerotire with small size and comprises the following techniques: (1) the exhaust aperture on a tyre mold is reduced; (2) sidewall rubber is thickened; (3) before optimum cure, the time of collecting inner-pressure heat water and the outer temperature warming are shortened; (4) the sizing pressure is reduced and the time of sizing is prolonged. The invention has the advantages that by adopting technique, the problem of the exposed stitching of the side wall of the aerotire is solved, and the production qualification rate is increased.

Description

technical field [0001] The invention relates to small-sized aviation tires, in particular to a method for preventing sidewall exposure of small-sized aviation tires. Background technique [0002] Small size aviation tires mainly refer to 6 For the following aircraft tires, due to the characteristics of the specifications, the number of carcass plies is less, generally only 2-4 layers, and the sidewall is thinner, generally 0.5-1.0mm, so the vulcanization process is difficult to control. The process stability is poor, and the problem of sidewall exposed lines is very likely to occur after vulcanization, resulting in a decline in the product qualification rate, and the qualification rate is even less than 50% in severe cases. Contents of the invention [0003] The purpose of the invention is to disclose a method for preventing sidewall exposure of small-size aviation tires. [0004] The technology that realizes the purpose of the invention taken is: [0005] 1. Reduce th...
