AI Technical Summary

Problems solved by technology

For example, the "low hysteresis" requirement requires a rubber compound with low filling and high crosslinking, but this leads to poor electrical conductivity and low structural durability

Abstract

The invention relates to a rubber blend, in particular for vehicle tyres and various types of belts and hoses. Said rubber blend is characterised by the following composition: 60 to 85 phr of at least one natural or synthetic polyisoprene; 15 to 40 phr of at least one butadiene rubber and / or of at least one styrene butadiene rubber which is solution-polymerised and has a glass transition temperature of less than or equal to -55C; 5 to 15 phr of at least one process oil; 15 to 75 phr of at least one silicic acid; 2 to 10 phr of at least one adhesive resin and; other additives.

Description

technical field [0001] The invention relates to a rubber compound, in particular for pneumatic tires and for belts, drive belts and hoses. Background technique [0002] The rubber composition of the tread determines to a large extent the running characteristics of a tire, especially a pneumatic tire. Similarly, the rubber compounds used in drive belts, hoses and other belts, especially where they are subjected to high mechanical loads, are essentially responsible for the stability and longevity of these rubber items. Therefore, the requirements imposed on these rubber compounds for pneumatic tires as well as for belts, drive belts and hoses are very stringent. [0003] In order to improve the running characteristics, the tread, for example, of a pneumatic tire, is often divided into two parts: an upper tread part, which is in direct contact with the road and is called the cap, And the second is the lower tread portion below, also known as the base. [0004] Here the base ...
