Title
(EN) EPOXIDE MICROCAPSULES WITH PICKERING EMULSIFIERS
(FR) MICROCAPSULES D'ÉPOXYDE AVEC ÉMULSIFIANTS DE PICKERING
Abstract
(EN)
Particles of encapsulated first epoxy resin (microcapsules) comprise: a) a core of first epoxy resin, within b) a shell comprising an organic polymer, and c) a layer of oil-in-water Pickering emulsifier particles borne on an outer surface of the shell. These particles may be used in liquid adhesive compositions, solid adhesive compositions such as tapes, or in other applications. In various embodiments, the oil-in-water Pickering emulsifier particles comprise materials selected from the group consisting of silica, fumed silica, calcium carbonate, barium sulfate, clay, carbon black, iron oxide, carbon nanotubes, latex, block copolymer micelles, polystyrene, poly(methyl methacrylate), any of the preceding materials which additionally are surface-modified, and combinations thereof. Particles of encapsulated epoxy resin may have an average diameter of 0.1-1000 micrometers, or in some embodiments 30-300 micrometers. The oil-in-water Pickering emulsifier particles may have an average diameter of 5-1000 nanometers, 5-100 nanometers, or in some embodiments 5-50 nanometers.

Des particules de première résine époxy encapsulée (microcapsules) comprennent : a) un noyau de première résine époxy, à l'intérieur de b) une enveloppe comprenant un polymère organique, et c) une couche de particules d'émulsifiant de Pickering huile dans l'eau portées sur une surface externe de l'enveloppe. Ces particules peuvent être utilisées dans des compositions adhésives liquides, des compositions adhésives solides telles que des bandes, ou dans d'autres applications. Dans divers modes de réalisation, les particules d'émulsifiant de Pickering huile-dans-l'eau comprennent des matériaux choisis dans le groupe constitué par la silice, la silice fumée, le carbonate de calcium, le sulfate de baryum, l'argile, le noir de carbone, l'oxyde de fer, les nanotubes de carbone, le latex, les micelles de copolymère séquencé, le polystyrène, le poly (méthacrylate de méthyle), l'un quelconque des matériaux précédents qui sont en outre modifiés en surface, et des combinaisons de ceux-ci. Les particules de résine époxy encapsulée peuvent avoir un diamètre moyen de 0,1 à 1000 micromètres, ou dans certains modes de réalisation de 30 à 300 micromètres. Les particules d'émulsifiant de Pickering huile-dans-l'eau peuvent avoir un diamètre moyen de 5 à 1000 nanomètres, 5 à 100 nanomètres, ou dans certains modes de réalisation de 5 à 50 nanomètres.
