Abstract
The invention discloses a trend rubber for helicopter tires. The rubber is made from natural rubber as the main material, and 3-polybutadiene rubber, intermediate super abrasion resistant carbon black and anti-vulcanization reducer as auxiliary materials which are mixed in certain proportions. By adding the 3-polybutadiene rubber, and intermediate super abrasion resistant carbon black, the trend rubber can be resulted to have appropriate dampness and favorable abrasion resistance; by adding the anti-vulcanization reducer, the rubber material can be resulted to have favorable thermal stability. Compared with the prior art, the trend rubber for helicopter tires of the invention has the advantages of high tensile strength, favorable flex cracking resistance, favorable thermal stability and higher dampness. The helicopter tires using the trend rubber have favorable damping performance and increases the riding comfort when the helicopter lands on the ground.
Description
Technical field
The present invention relates to aviation tire tread glue, be specifically related to trend rubber for helicopter tires.
Background technology
The vibrations of generation when vertiplane when landing mainly reduces to land with tire by the damping device of vertiplane jointly, at present the used aviation tire tread glue of vertiplane is to improve wear resistance and thermotolerance, because its damping capacity is not high, the vibrations that make vertiplane produce when landing can not be alleviated preferably.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of trend rubber for helicopter tires.This tread rubber has higher damping capacity when possessing good thermotolerance and fatigue performance.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
The vertiplane aviation tire tread glue is made of following component by weight:
