Abstract

L'invention concerne un mélange thermoplastique à base d'amidon servant à produire des corps moulés biodégradables présentant des propriétés de préférence mécaniques, améliorées, pouvant être obtenu par préparation et mélange de A) 100 parties en poids d'un amidon quelconque, corrigé par un calcul de façon à présenter une teneur en eau égale à 0 %, naturel, modifié chimiquement, produit par fermentation, recombinaison et/ou biotransformation, et/ou les dérivés dudit amidon; B) éventuellement jusqu'à 100 parties en poids d'un matériau polymère différent de A), biodégradable, présentant une innocuité physiologique et pouvant être transformé par voie thermoplastique; C) 1 à 100 parties en poids d'eau; D) au moins un plastifiant dans une proportion comprise entre 10 parties en poids et la moitié de la somme des parties en poids A) et B); E) au moins un phosphate, de préférence un sel d'acide phosphorique, dans une proportion comprise entre 0,01 partie en poids et (A)+ B))/10 parties en poids; F) éventuellement jusqu'à (A)+B)) d'autres additifs usuels. Au moins le mélange des composants E) et des composants A) s'effectue par introduction d'énergie thermique et mécanique dans le mélange thermoplastique, de préférence à une température élevée et par application simultanée de forces de cisaillement audit mélange.
