Formula according to embodiments of the invention 3 is made tire by commercially available conventional tyre as a control group 1 by inventor
Wear-resistant tyre behind face as invention group, will not contain in the first tread rubber in phenolic resin and the second tread rubber without styrene-
Butadiene-styrene block copolymer, polyethylene, polrvinyl chloride and epoxy resin, remaining is matched somebody with somebody with embodiments of the invention 3
The tire as a control group 2 of side and manufacturing conditions all same, above-mentioned three groups of Tire testing correlation performance parameters are as shown in table 1 below,
By matched group 1 and invention group in 100 DEG C of aging 48h, it is aging before and it is aging after data it is as shown in table 2.
1 tire correlation performance parameters of table
| Detection project | Matched group 1 | Invention group | Matched group 2 |
| 60 DEG C of Tan δ@(rolling resistance) | 0.313 | 0.151 | 0.292 |
| 0 DEG C of Tan δ@(wet earth-grasping force) | 0.357 | 0.465 | 0.364 |
| Abrasion performance index | 100 | 118 | 102 |
2 tire aging performance parameter of table
As can be seen from Table 1, matched group 1 and matched group 2 are compared using the invention group of wear-resistant tyre of the present invention, with compared with
Good wet earth-grasping force, improves wetland driving safety coefficient, improves the water-proof skid-proof performance of tire, while having good wear-resisting
The s-B-S added in consumption energy, the phenolic resin added in showing the first tread rubber and the second tread rubber
Block copolymer, polyethylene, polrvinyl chloride and epoxy resin make tire have more preferable wearability and non-skid property.
As can be seen from Table 2, the conventional tyre in matched group 1 is compared using the invention group of the wear-resistant tyre of the present invention, is sent out
In bright group it is aging before and after the change for determining stretch, breaking tenacity, percentage elongation and tearing strength much smaller than aging in matched group 1
Change in front and back, so as to the resistance to ag(e)ing for showing the wear-resistant tyre of the present invention is better than conventional tyre.
Although embodiment of the present invention is disclosed as above, which is not restricted to listed by description and embodiment
With, it can be applied to various suitable the field of the invention completely, for those skilled in the art, can be easily
Other modification is realized, therefore under the general concept limited without departing substantially from claim and equivalency range, the present invention is not limited
In specific details and shown here as the legend with description.
