Abstract

Ces dispersions aqueuses contiennent 20 à 60 % en poids d'un polyamidimide ayant un diamètre de particules inférieur à 5 micros et 1 à 6 % en poids d'un colloïde protecteur susceptible d'être dilué à l'eau, et le polyamidimide est un produit de condensation de : a. 35-45 % en poids d'au moins une diamine aromatique, b. 10-60 % en poids d'au moins un anhydride d'acide triacarboxylique aromatique ou de ses dérivés, c. 5-45 % en poids d'acide hexane-, pentane- et/ou butane-tétracarboxylique ou de leurs dérivés et d. 0-20 % en poids d'acide tétracarboxylique aromatique ou de ses dérivés; pour les préparer, le polyamidimide est tout d'abord séché, puis broyé finement à l'état humide, à l'aide de broyeurs de mise en dispersion qui présentent une forte densité d'énergie locale. Ces dispersions aqueuses de polyamidimides conviennent comme vernis d'émaillage pour fils, ainsi que pour la fabrication de produits d'imprégnation et de collage résistants à la température.These aqueous dispersions contain 20 to 60% by weight of a polyamidimide having a particle diameter of less than 5 microns and 1 to 6% by weight of a protective colloid capable of being diluted with water, and the polyamidimide is a condensation product of: a. 35-45% by weight of at least one aromatic diamine, b. 10-60% by weight of at least one aromatic triacarboxylic acid anhydride or its derivatives, c. 5-45% by weight of hexane-, pentane- and / or butane-tetracarboxylic acid or their derivatives and d. 0-20% by weight of aromatic tetracarboxylic acid or its derivatives; to prepare them, the polyamidimide is first of all dried, then finely ground in the wet state, with the aid of dispersing mills which have a high local energy density. These aqueous dispersions of polyamidimides are suitable as enamelling varnishes for threads, as well as for the production of temperature-resistant impregnation and bonding products.
