The invention relates to a method of promoting the adhesion of textiles to rubber compounds through a vinyl compound plasma pre-treatment procedure and a subsequent aplication of resorcinal-formaldehyde latex (RFL) to the textile surface. The inventive method encompasses a process through which free radicals of compounds comprising strong carbon-carbon bonds form a film over textile films and then covalently bonded to the resin component of the RFL. Such a method thus produces an extremely strong and versatile adhesive that facilitates adhesion between rubber compounds and heretofore unusable or difficult-to-use textiles. The resultant textile/rubber composites are utilized as reinforcements within such materials as automobile tires, fan belts, conveyor belts, and the like. Such materials and composites are also contemplated within this invention.
L'invention concerne un procédé favorisant l'adhésion de textiles à des composés caoutchoutés par une procédure de traitement au plasma de composé vinylique et l'application ultérieure de latex de résorcinol-formaldéhyde (RFL) sur la surface du textile. Le procédé de l'invention consiste en un processus dans lequel des radicaux libres de composés comprenant des liaisons carbone-carbone forment un film sur des films de textile et sont ensuite liés de manière covalente au composant résineux de RFL. Ledit procédé permet la production d'un adhésif polyvalent très puissant qui facilite l'adhésion entre des composés caoutchoutés et des textiles inutilisables ou difficiles à utiliser jusqu'à maintenant. Les composites de textile/caoutchouc résultants sont utilisés en tant que renforts dans des produits, tels que des pneumatiques d'automobile, des courroies de ventilateur, des bandes transporteuses et similaire. Lesdits produits et composites sont également décrits.
