Abstract
A method of increasing the wear resistance of a vulcanized elastomeric body having a surface region exposed to load, for instance a tire, cone or V-belt, conveyor belt, hose, resilient element, floor covering or the like, by changing its tensile stress state, wherein the elastomeric body is at least partially treated, including the surface region exposed to load, with a swelling agent constituting a medium which is soluble in the elastomer.
Claims25
A method of increasing the wear resistance of a vulcanized elastomeric body having a surface region exposed to load containing at least one reinforcement element, for instance, a tire, V-belt, conveyor belt, hose, resilient element, floor covering or the like, by changing its stress state, comprising the steps of:
- providing an elastomeric body with at least one reinforcement element;
- treating only the surface region exposed to load of the elastomeric body by impregnating said elastomeric body with a swelling agent comprising a medium which is soluble in the elastomer of the elastomeric body in an amount effective for swelling said treated portion,
- the distribution of the swelling agent diminishing from the region of said treated region of the elastomeric body towards the reinforcement element.
A method of increasing the wear resistance of a vulcanized elastomeric body having a surface region exposed to load, for instance a tire, V-belt, conveyor belt, hose, resilient element, floor covering or the like by changing its stress state, comprising the steps of:
- providing an elastomeric body;
- treating only the surface region exposed to load of the elastomeric body by impregnating said elastomeric body with a polymerizable swelling agent comprising a medium which is soluble in the elastomer of the elastomeric body in an amount effective for swelling said treated portion;
- swelling only part of the elastomeric body with the swelling agent;
- and
- following the swelling step polymerizing the swelling agent.
