Problems solved by technology

The balance film glue used in the past cannot easily correct the static unbalance difference value caused by process fluctuations in the production process of aviation tires, and cannot meet the requirements for tire static balance during tire use, resulting in static unbalanced In addition, due to the weak combination of the balance film and the inner surface of the tire, there will be falling off, falling blocks or other quality problems, which will affect the safety of the aircraft

Embodiment Construction

[0022] Through the specific embodiments of the present invention given below, the present invention can be further understood, but it is not a limitation of the present invention.

[0023] Weigh 1 # Smoke sheet glue 1000Kg, pine tar 80kg, high wear-resistant carbon black 250Kg, lead tetroxide 2500Kg, ketone amine antioxidant 20Kg, sulfur 30Kg, sulfenamide accelerator 10kg, zinc oxide 50Kg, stearic acid 20Kg , The balance film rubber for aviation tires is made through an internal mixer.

[0024] The balance film glue is discharged with an open mill with a roller distance of 3-4mm, and then according to the measured static balance difference value, a certain weight of film is cut out, and a 0.5-1mm thick high-strength rubber material is covered and put in Pre-vulcanization is performed in the vulcanization mold to obtain a balanced film.

[0025] The bonding method when using the balance film: first grind the surface of the balance film and the adhered part of the tire, clean the gr...

Abstract

The present invention discloses a balanced film rubber and a balanced film of aviation tyre. The balanced film rubber is mixed and refined according to a certain proportion of natural rubber which is used as the main material, lead orthoplumbate, high-abrasion carbon black, pine tar, ketoamine type anti-aging agent, sulfur and sulfenamide type accelerator which are used as the main auxiliary materials; the balanced film rubber is used to manufacture the balanced film. The external layer of the balanced film rubber is coated with a thin layer of high-strength sizing material so as to manufacture the balanced film through prevulcanization. The balanced film rubber has the characteristics of large specific gravity and good adhesive performance with the sizing material on the surface of the internal cavity of the tyre. Static unbalanced sticking patch used for aviation tyre can repair the static disbalance of aviation tyre well, meet the static balance requirement of tyre and prolong the service life of tyre.

Description

Technical field: [0001] The invention relates to a rubber for aviation tires, in particular to a balance film rubber and a balance film for aviation tires. Background technique: [0002] Aviation tires require high tire balance under high-speed and high-load conditions. The balance film rubber used in the past cannot easily correct the difference in static imbalance caused by process fluctuations in the production process of aviation tires, and cannot meet the requirements for static balance of tires during the use of tires, resulting in static imbalances. Bumps and jumps. In addition, because the balance film is not firmly bonded to the inner surface of the tire, it will fall off, fall off, or other quality problems, which will affect the safety of the aircraft. Summary of the invention: [0003] The purpose of the present invention is to disclose a balance film glue and a balance film for aviation tires that have a high specific gravity and good adhesion to the tire inner cavi...
