摘要： Tyres for vehicle wheels having reduced environmental impact and the components thereof, in particular reinforcing structural elements such as carcass structures, belt structures, flippers and chafers, include elongated reinforcing elements treated with resorcinol and formaldehyde-free cross-linkable adhesive compositions. The adhesive compositions include at least a) a rubber latex, at least b) an epoxide and at least c) a polyamine with molecular weight higher than 190 Daltons, including at least two amino groups selected from primary —NH2 and secondary —NH— amino groups. In the structural element, these compositions confer an adhesion between cords and compounds that is comparable to, if not better than, the traditional RFL system in use in this sector. Furthermore, by suitably modifying the compound compositions in the reinforced structural elements and, possibly, also in the other elastomeric components of the tyre, it is possible to manufacture tyres while avoiding the use of toxic chemicals, such, as resorcinol and formaldehyde.

摘要： The aqueous adhesive composition comprises: - a phenol-aldehyde resin based: - on an aromatic polyaldehyde bearing at least two aldehyde functions, comprising at least one aromatic nucleus, and - on a polyphenol, comprising one or more aromatic nuclei with: in the case of a single aromatic nucleus, the latter bears two or three hydroxyl functions in the meta position in relation to one another, the rest of aromatic nucleus being unsubstituted, in the case of a plurality of aromatic nuclei, at least two thereof each bear two or three hydroxyl functions in the meta position in relation to one another, it being understood that the two positions ortho to at least one of these hydroxyl functions are unsubstituted, - less than 16% by weight of unsaturated diene elastomer latex.
