RUBBER/CORD COMPOSITE AND PNEUMATIC TIRE USING THE SAME |
摘要 |
<p>A rubber-cord complex 9 having an improved wet heat adhesive property between a rubber and a cord comprising a drawn plated wire, and including a cord 10 comprising a drawn plated wire 17 prepared by providing a brass plated layer 16E on the surface of an element wire 15 and drawing the resulting plated wire, and a rubber 12 vulcanized and bonded to the cord 10, wherein the rubber-cord complex 9 has an adhesion reaction layer 25 formed by a cross-linking reaction of sulfur and copper, between the rubber 12 and the brass plated layer 16E, and in a wet heat deterioration state after being subjected to the vulcanization to bond the rubber 12 thereto and further held under an atmosphere having a temperature of 50 to 100°C and a humidity of 60 to 100% for one hour to 20 days, the adhesion reaction layer 25 has an average thickness of 50 to 1,000 nm, and the interface S between the adhesion reaction layer 25 and the rubber has a fractal dimension of 1.001 to 1.300.</p> |
