(FR) PROCEDE DE PREPARATION DE MELANGES DE LATEX CHIMIQUEMENT ET PHYSIQUEMENT STABLES JUSQU'A LA FORMATION DE FILMS
Abstract:
(EN) This invention provides the composition, preparation, and end-use of waterborne cross-linking technology based compositions prepared from water-based latexes. The invention provides a water-based latex comprising dispersed, waterborne amino-functional polymer particles; dispersed, waterborne pendant-functional polymer particles; and water. The waterborne pendant-functional polymer comprises at least one pendant amine reactive functional moiety selected from the group consisting of carbonate, epoxide, isocyanate, isopropenyl, carboxylic acid, and allyl groups. In a preferred embodiment, a latex of the invention comprises dispersed, waterborne polymeric (polyamino)enamine (PPAE) particles; dispersed, waterborne pendant-functional polymer particles; and water. The PPAE is the reaction product of a surfactant-stabilized acetoacetoxy-functional polymer (SAAP) and a poly(alkylenimine). The water-based latexes of the invention provide stable emulsions containing a blend of waterborne polymer particles which undergo cross-linking upon film formation. The latex films or coatings may be cured at ambient temperatures or may be thermally cured. The latex is useful in variety of coating compositions such as, for example, paints, inks, sealants, and adhesives.
(FR) L'invention porte sur la composition, la préparation, et l'utilisation finale de compositions aqueuses faisant appel aux techniques de réticulation préparées à partir de latex à base aqueuse, et sur un latex à base aqueuse constitué: de particules de polymère à fonction amino en dispersion aqueuse, de particules de polymère à fonction pendante en dispersion aqueuse, et d'eau. Le polymère à fonction pendante en dispersion aqueuse comporte au moins un fragment à fonction amine réactive pendante sélectionnée parmi carbonate, époxyde, isocyanate, isopropényle, acide carboxylique et des groupes allyle. Dans la réalisation préférée, le latex de l'invention comprend en dispersion aqueuse des particules polymériques de (polyamino)énamine (PPAE), des particules de polymère à fonction pendante en dispersion aqueuse, et de l'eau. Le PPAE est le produit de réaction d'un polymère à fonction acétoxy stabilisé par tensio-actif (SAAP) et d'une poly(alkylénime). Les latex à base aqueuse de l'invention sont des émulsions stables contenant un mélange de particules de polymères dans l'eau qui se réticulent lors de la formation du film. Les films ou revêtements de latex durcissent à la température ambiante ou à la chaleur. Ces latex peuvent entrer dans différentes compositions pour revêtements telles que par exemple des peintures, des encres, des mastics ou des adhésifs.
