Abstract
This invention relates to rubber reinforcing material with reduced weight, a method for preparing the same, and a tire including the same. According to this invention, there is provided a rubber reinforcing material that has a thin thickness and a light weight, and yet has excellent durability. The reinforcing material not only reduces the weight of a tire, but also enables realization of improved rolling resistance.
Claims15
A rubber reinforcing material comprising:
- a fiber base;
- an adhesive layer placed on the fiber base;
- and
- a rubber compound layer placed on the adhesive layer,
- wherein the rubber compound layer has a thickness of 2 to 200 , a t50 value of 150 to 220 seconds, and a t90 value of 300 to 350 seconds
- (wherein, the t50 value is a time (seconds) required to reach 50% of the maximum crosslinking density of the rubber compound layer, measured by a rheometer according to the ASTM D2084 standard test method, and the t90 value is a time (seconds) required to reach 90% of the maximum crosslinking density).
