dc.descriptionNine formulations of a flame retardant masterbatch with low environmental impact were developed, and the influence of their incorporation into a linear low-density polyethylene, grafted with a vinyltrimethoxysilane crosslinking agent, was evaluated for further crosslinking in order to obtain a cross-linked polyethylene with flame retardancy. The MBFRs were prepared using N, N-ethylene bis (tetrabromophthalamide) blended with antimony trioxide, zinc borate, linear low-density polyethylene, dispersing agent, and polyethylene wax, varying the N, N-ethylene bis (tetrabromophthalamide) (36, 42, and 45 %) and the dispersing agent (0.50, 1.25, and 2.00 %), while the rest of the components were kept constant. Subsequently, the nine developed flame retardant masterbatch were blended with the grafted linear low-density polyethylene to produce nine flame retardant cross-linked polyethylene compounds that were later shaped into plates and 14 AWG cable insulation for physicochemical characterization. The level used in both the fillers (N, N-ethylene bis-tetrabromophthalamide, antimony trioxide and zinc borate) and the dispersion agent conditioned the level of crosslinking estimated from the gel content, the flow performance, and the flame behavior of the material; the first two properties were favored by the increase in the dispersing agent, while the latter was improved with the increase in the proportion of fillers in the mixture. Likewise, the evaluation of the flame retardant cross-linked polyethylene compound manufactured with a commercial MBFRC, taken as a reference, showed that some of the formulations analyzed in this study can be used for electric cable insulation.en-US
dc.descriptionSe desarrollaron nueve formulaciones de un masterbatch retardante a la llama de bajo impacto medioambiental y se evaluó la influencia de su incorporación en un polietileno lineal de baja densidad, injertado con un agente de entrecruzamiento viniltrimetoxisilano, para su posterior reticulación con el fin de obtener un polietileno entrecruzado con retardancia a la llama. Los masterbatch retardantes a la llama se prepararon a partir del uso de N, N-etilen bis(tetrabromoftalamida), mezclado con: trióxido de antimonio, borato de zinc, polietileno lineal de baja densidad, agente de dispersión y cera polietilenica, variando el N,N-etilen bis(tetrabromoftalamida) (36, 42 y 45 %) y el agente de dispersión (0.50, 1.25 y 2.00 %), mientras se mantuvo constante el resto de componentes. Posteriormente, los nueve masterbatch desarrollados se mezclaron con el polietileno lineal de baja densidad injertado para la producción de nueve compuestos de polietileno entrecruzado retardante de lama que luego se conformaron en forma de placas y aislamiento de cable 14 AWG para su caracterización fisicoquímica. Se encontró que el nivel empleado tanto en las cargas (N,N-etilen bis-tetrabromoftalamida, trióxido de antimonio y borato de zinc) como en el agente de dispersión condicionaron el nivel de entrecruzamiento estimado a partir del contenido de gel, las características de flujo y el comportamiento frente a la llama del material; siendo favorecidas las primeras dos propiedades con el incremento del agente de dispersión, en tanto que la última se vio mejorada con el aumento en la proporción de las cargas usadas. De igual manera, la evaluación de un compuesto de polietileno entrecruzado retardante a la llama fabricado con un masterbatch retardante a la llama comercial, tomado como referencia, evidenció que algunas de las formulaciones trabajadas en esta investigación son susceptibles de ser empleadas para el aislamiento de cables eléctricos.es-ES
