Title:
SPECIAL BIOMASS COLOR MASTERBATCH FOR DEGRADABLE PLASTIC AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/103116
Kind Code:
A1
Abstract:
A special biomass color masterbatch for a degradable plastic and a preparation method therefor. The special biomass color masterbatch is prepared from the following components: a plant coloring agent, cyclodextrin, a flame retardant, a modified polylactic acid, a plasticizer, an ultraviolet light absorber, an anti-aging agent, an inorganic filler and sodium stearate. As the color masterbatch, which is prepared by means of the modification treatment of a polylactic acid and cooperation between the modified polylactic acid and other components, is introduced into a degradable plastic, the comprehensive performances of the degradable plastic can be greatly improved, in particular, the tensile strength and the flame retardant property are obviously improved; moreover, the degradation performance of the degradable plastic is not influenced.
