Abstract

The invention belongs to the technical field of polymer material processing and preparation, and in particular relates to a high-performance PBS composite material and a preparation method thereof. The composition comprises the following components by weight: 100 parts of PBS, 1-15 parts of organic salt microspheres, and 0.02-0.30 parts of anti-hydrolysis agent. The particle size of the organic salt microspheres adopted in the present invention is controllable and uniformly dispersed in PBS, and can increase the heat distortion temperature of PBS and reduce the glass transition temperature of PBS; the PBS composite material prepared by the present invention belongs to a fully biodegradable material, And the raw material comes from biomass resources, which fundamentally solves the problems of resource shortage and white pollution; the PBS composite material prepared by the present invention only needs simple physical blending, its preparation process is simple, equipment investment is small, and the operation process is easy to implement .

Description

technical field [0001] The invention belongs to the technical field of polymer material processing and preparation, and in particular relates to a high-performance PBS composite material and a preparation method thereof. Background technique [0002] Polybutylene succinate (PBS) is obtained by condensation polymerization of succinic acid and butanediol. PBS resin is milky white, odorless and tasteless, and is easily metabolized by various microorganisms in nature or enzymes in animals and plants. , decomposed into carbon dioxide and water, is a typical fully biodegradable material, which can solve the environmental pollution caused by traditional plastics; at the same time, PBS has good biocompatibility and bioabsorbability, so it is widely used in medical materials, drug carriers and other fields. It also has a good application prospect. [0003] However, PBS has poor notched impact strength, slow crystallization rate, highly hydrophobic chain structure, lack of active sit...
