Abstract
The rubber material for retreading tyre facing is compounded with the material including natural rubber, zinc oxide, stearic acid, carbon black, white carbon black, Si-69, antiager A, antiager 4010NA, antiager H, dimorphiline disulfide, N-cyclohexyl-2-benzothiazole sulfenamide, sulfur powder, oil insoluble sulfur, modified alkylphenol resin, N-cyclohexyl thiophthalimide and aromatic oil. The retreaded tyre with the said rubber material has better cutting and pricking resistance.
Description
Technical field
The present invention relates to a kind of new tyre facing rubber material for retreading tyre of giant mining engineering machinery, this tread mix is used for the tyre surface of renovated tyre, and the tyre surface when being mainly used in the 3600R51 tyre rebuilding is handled.
Background technology
The continuous increase of modern bargh traffic capacity, impel the mine carrier vehicle to develop to the direction that maximizes, the vehicle load tonnage is increasing, and the road conditions in mine is more abominable, thereby the tyre surface position of tire very easily is subjected to cutting and puncture and cause heel and toe wear to damage, and has higher requirement with regard to the tread mix of giving this tire for this reason.Chinese patent ZL01104025.4 discloses a kind of high trans-1, the high-speed and energy-saving tire tread compound of 4-polyisoprene and high vinyl polybutadiene and usefulness, it is characterized in that, in the tread mix prescription, used high trans-1 simultaneously, 4-polyisoprene (being called for short TPI) and high vinyl polybutadiene (being called for short HVBR), and with other tire rubber commonly used such as natural rubber (NR); styrene-butadiene rubber(SBR) (SBR; comprise the poly-butadiene-styrene rubber ESBR of breast; solution polymerized butylbenzene glue SSBR and oil-filled butadiene-styrene rubber etc.); cis-1,4-polybutadiene rubber at least a blend such as (BR); covulcanization; what make both has low-rolling-resistance and low dynamic heat build up, a rubber tyre that has high wet road-traction (high wet-sliding resistant performance) again.Cooperate the preparation of blend covulcanization with other conventional rubber.For example, the natural gum of prescription employing 20-25 mass parts TPI and 20-25 mass parts HVBR replacement equivalent or butadiene-styrene rubber or cis-butadiene cement etc. are as the sizing material of tyre surface, can reduce tire drag 15-20%, save fuel oil about 2.5%, be a kind of more satisfactory tread mix.But this tread mix lacks higher wear resistance and anti-puncture, therefore, needs to propose a kind of the have excellent anti-cutting and the tread mix of anti-puncture performance.
Summary of the invention
The new tyre facing rubber material for retreading tyre that the purpose of this invention is to provide a kind of giant mining engineering machinery, this tread mix can further improve the anti-cutting and the anti-puncture performance of tread rubber under the prerequisite that satisfies tire use over-all properties.
