Abstract

"EMULSõES PARA PRODUTOS DE LIGNOCELULOSE, MéTODOS DE SUA FABRICAçãO, PRODUTOS DE LIGNOCELULOSE MELHORADOS E MéTODOS PARA SUA FABRICAçãO". São providas emulsões as quais são úteis na impressão de resistência à água a produtos de lignocelulose. Em uma modalidade, as emulsões contêm uma cera não saponificável, uma cera saponificada, um componente de alquil fenol, um dispersante / tensoativo, tal como um sal de ácido polinaftalenossulfónico, e carboximetilcelulose. Tais emulsões podem ser adicionadas à água quente, mesmo fervendo, sem a emulsão se separar ou talhar. Várias modalidades são estáveis por períodos estendidos de tempo, quando armazenadas à temperatura ambiente, não requerem a adição de um biocida conservante para se evitar contribuir para a biodegradação em um produto de lignocelulose. As emulsões são liquidos vazáveis à temperatura ambiente. Opcionalmente, as emulsões podem ser adicionadas a produtos de lignocelulose com um conservante, para se evitar que o conservante seja lixiviado.
