CA 2644674

The present invention relates to biodegradable protein based thermoset compositions formulated from a powder of a dry and finely ground protein material, from which the water has been thoroughly removed, an anhydrous and liquid alcohol and other optional additives. The inventions also relates to the method for obtaining these compositions in which the components are homogeneously mixed, under controlled conditions of temperature and moisture, to obtain a homogenous and shelf-cohesive mass, that can be shaped in any predetermined form by diverse molding methods, being readily set through the application of a certain amount of heat during a short period of time, which enables it to turn into a solid shaped body or article through a very simple process.

La présente invention concerne des compositions thermodurcissables à base de protéines biodégradables formulées à partir d'une poudre de matériau protéinique sec et finement broyé, duquel l'eau a été soigneusement éliminée, d'un alcool anhydre et liquide et d'autres additifs éventuels. L'invention concerne également le procédé d'obtention de ces compositions, selon lequel les composants sont mélangés de manière homogène, dans des conditions contrôlées de température et d'humidité, afin d'obtenir une masse homogène et cohésive pouvant être mise sous toute forme prédéterminée par divers procédés de moulage, pouvant facilement être durcie par application d'une certaine quantité de chaleur pendant une courte période de temps, ce qui permet de la transformer en un corps ou un article moulé solide par un procédé très simple.
