Abstract
La présente invention concerne un matériau de PGA modifié hautement cristallin ainsi qu'un procédé de préparation associé. Le matériau de PGA modifié est préparé à partir des matières premières suivantes, en parties en poids : de 70 à 80 parties d'une résine d'acide polyglycolique, de 5 à 15 parties d'une charge, de 4 à 25 parties d'un plastifiant et de 0,5 à 1 partie d'un agent de nucléation ; le plastifiant est un mélange d'alcool polyvinylique et de glycérol qui ont un rapport en masse de 1/1,8-2,3, le poids moléculaire de l'alcool polyvinylique étant de 300 à 500 g/mol, et le degré d'alcoolyse étant supérieur ou égal à 98 % ; l'agent de nucléation est sélectionné parmi une ou plusieurs de la poudre de talc, de l'inositol et d'un diméthylphényl hydrazide d'acide sébacique ; et la charge est sélectionné parmi une ou plusieurs de la nano-montmorillonite, du nanocarbonate de calcium, et d'un amidon comestible. En modifiant la résine d'acide polyglycolique à l'aide du plastifiant, de l'agent de nucléation et de la charge desdits types, le matériau de PGA modifié a une performance cristalline relativement élevée et peut être utilisé pour préparer un produit à haute résistance à la chaleur. La température de ramollissement Vicat est de 205 à 210 °C ; le temps de semi-cristallisation est de 5 à 15 s ; et la cristallinité relative est de 45 à 47 %.
