Abstract
Partial epoxidation of natural rubber has been carried out in order to assess its effect on rubber-to-brass adhesion performance. Rubbers, with extents of epoxidation up to 60% of the double bonds presents, have been prepared. The adhesion performance of epoxidized rubbers to brass has been assessed using a peel adhesion test. The adhesion performance is improved for epoxidized rubbers compared with natural rubber. The adhesion performance of vulcanized samples of (a) epoxidized natural rubbers and (b) blends of natural rubber and expoxidized natural rubber, to brass-coated steel tyre cords has been measured by a standard (A.S.T.M.) method. Significant improvement of the initial (unaged) adhesion performance is achieved for the epoxidized rubbers and the rubbers blends, and this improved adhesion performance is maintained after heat ageing in air for the rubbers with an epoxide content of ca 10% or in the case of the rubber blends an equivalent (overall) epoxide content of ca 10%. This improvement in adhesion performance is achieved without sacrificing desirable physical properties of the rubber.
