Abstract

BThe invention relates to the field of biodegradable polymer materials, and in particular relates to a biodegradable polymer alloy compatilizer and a preparation method thereof; and the compatilizer comprises the following raw materials in parts by weight: 25-90 parts of polyhydroxyalkanoate, 25-80 parts of polylactic acid, 5-50 parts of poly butylene succinate, 0.1-3 parts of a lubricant and 0.1-5 parts of an active substance. The biodegradable polymer alloy compatilizer disclosed by the invention ensures the dispersion and reaction of reaction active substances, continuous increase the volume of a blended polymer by the compatilizer can be ensured in the using process of the compatilizer in the low-temperature processing process, the size of a dispersed phase is reduced, and the processing and using performances of a biodegradable polymer alloy are improved; and the strength, the toughness and the material transparency and the like of a melt of an incompatible biodegradable alloy system can be improved; and use of a biodegradable polymer alloy material in injection molding, film blowing, casting, extrusion, foaming and other processing fields can be expanded, the biological degradation characteristic of the material can be kept, and the biodegradable polymer alloy material has important practical application value.

Description

technical field [0001] The invention relates to the field of biodegradable polymer materials, in particular to a biodegradable polymer alloy compatibilizer and a preparation method thereof. Background technique [0002] While traditional plastics bring convenience to people's lives, they also cause serious environmental problems. The use of biodegradable materials provides a new solution for waste plastics. A single biodegradable polymer often cannot meet the use of conventional products. For example, films made of PBAT and PPC resins are soft and lack stiffness. High brittleness, it is necessary to add tough materials such as PBS, PCL, etc. to improve toughness. At the same time, due to the poor compatibility between the commonly used biodegradable materials, the mechanical properties of the materials are deteriorated and cannot meet the requirements of use, such as PLA is incompatible with PBAT, PCL, PBS, etc., thermoplastic starch TPS and PLA, PBAT, Resins such as PBS h...
