Abstract

L'invention concerne un filtre de cigarette biodégradable. Le filtre est préparé en utilisant la matière première de la fibre biodégradable pour cigarette. Le matériau comprend 90-100 % en poids de polybutylène succinate et 0-10 % en poids de stabilisants. Le polybutylène succinate est un type de polymère et la quantité de chaînes de butylène succinate dans la chaîne de molécule polymère est supérieure à 70 % des chaînes totales. Le polymère a un poids moléculaire moyen de 50 000-350 000 et un indice de dispersion de 1,2-3,0. La fibre pour cigarette est préparée par la technologie de filage à l'état fondu en utilisant la matière première. L'invention concerne un procédé de préparation du filtre de cigarette biodégradable au moyen de la fibre pour cigarette avec une forme fixe et un produit pour cigarette fourni avec le filtre. Le filtre de cigarette présente les mêmes performances que les filtres de cigarette communs. Le filtre de cigarette jeté par un fumeur se décompose en peu de temps dans l'environnement naturel. Le filtre de cigarette peut répondre aux besoins de fabrication de cigarettes tout en résolvant le problème de pollution environnementale causé par les déchets de cigarettes.
