Abstract RU 2261257 C1

FIELD: rubber industry.

SUBSTANCE: invention relates to manufacture of rubber-metal articles, in particular rubber-metal-cord tires and aims at providing metal-adhesion promoter for isoprene rubber in the form of fine iron compound powder. As iron compounds, ferrites, in particular iron oxide complexes with other metals being constituents of galvanic sludge, are used and composed of, wt %: Fe₂O₃ 30-80, CaO 0-16, BaO 0-16, ZnO 2-20, Cr₂O₃ 2-20, NiO 0-6, and CuO 0-8.

EFFECT: strengthened rubber-to-iron bond, reduced manufacture expenses, and utilized noxious galvanic sludge.
