Abstract

"PROCESSO DE FABRICAçãO DE UM MATERIAL COM MUDANçA DE FASE, QUASE INCOMPRESSìVEL, FLUIDIFICADO SOB CISALHAMENTO E DE BAIXA CONDUTIVIDADE TéRMICA". A presente invenção refere-se a um processo, que comporta a combinação com um material de mudança de fase no estado líquido (PCM), de um agente texturizador escolhido para reduzir muito a convecção térmica e cuja viscosidade é diminuída de forma reversível, sob cisalhamento. O material formado tem uma consistência gelificada no repouso, e fluidificada sob cisalhamento. O PCM é constituído em uma mistura de compostos químicos da família dos alcanos: parafinas, ceras, álcoois graxos, ácidos graxos, etc. e o agente texturizador é um polímero de forte massa (polímeros hidrocarbonados, polímeros de ésteres ou de éteres, polímeros mistos ésteres-hidrocarbonetos), um polímero ionómero ou um copolímero estirênico di, tri ou multiblocos (SBS: estireno-butadieno-estireno, SEBS: estireno-etilenobutadieno-estireno). Aplicações para o isolamento térmico de recipientes ou de condutor, e notadamente para o isolamento de condutos de transporte de hidrocarbonetos.
