Effect of Anion in Cobalt Promoters on the Adhesion between Steel Cord and Rubber Compound

There is widespread use of two main groups of adhesion promoters, the SRH-system and an organic cobalt salt. They are used either jointly or individually in the rubber compound for promotion and maintenance of good adhesion of rubber to brass-coated steel cord in radial tyres.

This paper describes the influence of anions associated with cobalt promoters on the adhesion energy and the pull-out force between brass-coated steel cord and rubber and their relationship to other relevant physical properties, under the influence of various environments which simulate tyre service conditions.

It is observed that incorporation of a cobalt promoter greatly enhances the adhesion energy and influences the Young's modulus and crosslink density of the rubber compound in a similar fashion. The study establishes the supremacy of boroacylate among the anions considering its overall good performance and the protection offered against various hostile environments. However, the benefits of the cobalt promoter is not realised with stearate ion. The results are explained on the basis of chemical stability of the promoter and the properties of the interfacial film and the compounds.     

Adhesion Between Rubber Compound and Copper-Film-Plated Steel Cord

Four copper-film-plated steel cords (abbreviated hereafter as copper-plated cord) with different thickness of copper film from 32 to 90 nm were prepared and their adhesion properties with rubber compound were investigated. Adhesion properties improved with the decrease in the thickness of the copper film. Unaged pull-out force and rubber coverage of copper-plated cords were inferior to those of brass-plated cord, but adhesion degradation was significantly slower on copper-plated cords resulting in better adhesion after humidity aging of 15 days and salt solution aging of 5 days. The excellent adhesion stability of copper-plated cords can be explained by the suppression of the excessive growth of copper sulfide and the inhibition of dezincification due to the small amount of copper plating and the lack of metallic zinc at the outer surface.

Effect of Tetrachlorobenzoquinone on the Adhesion between Rubber Compound and Brass-plated Steel Cord

The adhesion between tetrachlorobenzoquinone (TCBQ)-loaded rubber compound and brass-plated steel cord was studied to understand the role of TCBQ as an adhesion promoter. With loading of TCBQ in the rubber compound the cure rate became slow, but the change in physical properties was not significant. An improvement of the adhesion was obvious with low loading of TCBQ at the range of 0.5 phr while an adverse effect was observed with high loading at 2 phr. The addition of TCBQ for the improvement of adhesion has a greater effect before aging because TCBQ contributes to form a large surface area of copper sulfide via accelerated copper diffusion into the rubber bulk. However, higher TCBQ loading as well as longer aging time leads to a great extent of copper migration into the rubber and excess growth of zinc oxide layer, resulting in decreased adhesion. The adhesion interphase before aging, between a thin brass film and a rubber compound, investigated using AES showed no difference except that sulfur increased with increasing TCBQ loading. On the other hand, the adhesion inter-phase was changed after humidity aging. The copper content decreased at the adhesion interphase while it increased in the rubber layer with increasing addition of TCBQ.
