Description
Technical field
The present invention relates to technical field of polymer materials, particularly a kind of rubber combination that is applicable to tubeless tyre air retaining wall.The invention belongs to rubber industry and tire manufacturing technology field.
Background technology
Tubeless meridian tire has excellent high speed, comfortableness, security and economy, is applied to nearly all radial from tyres for passenger cars to off-the-road tyre in Europe.Tubeless meridian tire has been cancelled the inner tube of a tyre and rim strip, wheel total quality reduces, air retaining wall is a TR thin rubber layer of tubeless meridian inside tires, as keeping the required parts of the high inflation pressure of tire, stop gas and moisture to spread in carcass, thereby reduce carcass internal pressure, improve tire dynamic durability.
Air retaining wall is except requiring good resistance to air loss and ageing resistance, and require has good binding property and the inter-vulcanizability with other glue kinds simultaneously, and therefore halogenated butyl rubber is favored.The principal item of halogenated butyl rubber has chlorinated butyl rubber and brominated butyl rubber, and because its price is higher, tyre production enterprise faces larger cost pressure.
While making tire liner with halogenated butyl rubber, one of its basic demand will have good resistance to fatigue exactly, is easy to processing, has good resistance to air loss, and heat-dissipating is low, has good binding property between air retaining wall and cord body simultaneously.The viscosity that increases air retaining wall sizing material, is conducive to prevent cause air retaining wall joint cracking because viscosity is poor after moulding, and then causes the passive stretching of carcass ply, causes steel wire cord spacing to change.
Patent CN2827758Y(Granted publication day: on October 18th, 2006) a kind of novel engineering tyre with inner tube disclosed, between in air retaining wall and tire, increase the air retaining wall of one deck chlorinated butyl rubber and inner layer of tire rubber blending, both can improve in tire and the bond properties of former air retaining wall, and can further prevent from having a flat tire again.Patent CN202345294U(Granted publication day: on July 25th, 2012) a kind of engineering tyre that there will not be the delamination of air retaining wall tympanites, longer service life disclosed, between in air retaining wall and tire, increase one deck bonding air retaining wall, improve in tire the bond properties with air retaining wall, prevent from having a flat tire, improved the work-ing life of tire.But the method for this increase one deck air retaining wall can consume more starting material, not only tire weight increases, and manufacturing cost also can increase.
The present invention does not increase the quantity of air retaining wall, just improves for former air retaining wall sizing material.The invention provides a kind of rubber combination that is applicable to tubeless tyre air retaining wall, said composition forms body material by halogenated butyl rubber and natural rubber blend, carbon black and mineral filler are filled jointly, be aided with the Synergist S-421 95 such as vulcanizing agent, promotor, have the advantages that heat-dissipating is low, autohension is good, have good resistance to air loss and resistance to fatigue, strength and extension property and ageing-resistant performance are also better simultaneously.
Summary of the invention
1, goal of the invention:
