Abstract
Official abstract text for this publication.
A tire rubber compound having at least one cross-linkable, unsaturated-chain polymer base, and a curing system of at least sulphur, stearic acid, zinc oxide, and a chelating agent for complexing the zinc ion.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing a tyre rubber compound comprising a mixing step wherein a curing system is added and mixed to a compound being produced; said curing system comprising at least sulphur, stearic acid, and zinc oxide; said method being characterized in that a chelating agent for complexing zinc ion is added and mixed to the compound being produced together with said curing system in said mixing step; said chelating agent being EDTA or a chemical derived from EDTA, and said chelating agent chelates with zinc ions in said mixing step. 2. A method as claimed in claim 1 , characterized by comprising 0.1 to 5 phr of said chelating agent. 3. A method as claimed in claim 1 , characterized by comprising 0.1 to 10 phr of stearic acid, and 0.1 to 20 phr of zinc oxide. 4. A tyre rubber compound made according to the method as claimed in claim 1 .
