[0103] The slope of the stress-strain curve increases slightly with the addition of a small amount of HXNBR. For example, adding 2phr HXNBR (Example 2), M300 / M100 increased from 3.1 to 3.3.

[0104] DIN wear data is the most important sign to illustrate the reinforcement effect of HXNBR. As can be seen in Table 2, the DIN volumetric abrasion loss of the compounds with HXNBR content of 2 or 5 phr (Examples 2 and 3) is significantly lower than that of the control compound (Example 1). Moreover, the hardness of the compound increases with the increase of HXNBR content.

[0105] The stress-strain data and DIN volumetric wear losses suggest that adding small amounts of HXNBR to BIIR-containing tread compounds can improve the reinforcement of the physical properties of the resulting compounds. It appears that when HXNBR is below 5 phr, the degree of reinforcement will increase with increasing HXNBR content in the tread compound.

[0106] Although the hardness a...

Abstract

The present invention relates to a method of improving the hardness and abrasion resistance while maintaining the useful dynamic properties inherent to butyl based tire tread compounds by adding HXNBR to a rubber composition comprising at least one butyl elastomer for a tire tread, in particular a tire tread suitable for a pneumatic tire.

Description

technical field [0001] The present invention relates to a method for increasing the hardness and hardness of butyl-based tire tread compounds by adding HXNBR to a rubber composition comprising at least one butyl elastomer for the manufacture of tire treads, especially suitable for the manufacture of pneumatic tire treads wear resistance while maintaining its inherent beneficial dynamic properties. Background technique [0002] Tire tread development efforts have focused on optimizing various important physical properties, of which rolling resistance, wet traction and wear resistance are considered to be the most important properties. It has long been known that the addition of butyl elastomers to tread compounds has a positive effect on tread properties due to the unusual dynamic properties of butyl elastomers. Adding BIIR (brominated butyl elastomer) to the tread, for example, has been shown in laboratory tests to improve wet traction and rolling resistance. These two imp...
