Microcapsule starch-based bioplastic and preparation method

Abstract

Belonging to the technical field of bioplastics, the invention relates to a microcapsule starch-based bioplastic and a preparation method. Technically, the invention aims to provide a microcapsule starch-based bioplastic and a preparation method. The method utilizes the characteristic that the capsule wall material and matrix resin have good compatibility, bonds polyvinyl alcohol and starch as thecore, employs polytetrafluoroethylene as the capsule wall material to coat starch so as to obtain microcapsules, and disperses the microcapsules in resin to obtain masterbatch, thus improving the compatibility of starch and resin, and enhancing the mechanical properties of the film. Also compared with the conventional modification treatment process of starch biomass materials, microencapsulationtreatment solves the problem of tedious steps and broadens the application fields.

Description

technical field

[0001] The invention relates to a microcapsule starch-based bioplastic and a preparation method thereof, belonging to the technical field of bioplastics. Background technique

[0002] With the increasing energy crisis caused by oil shortage and the "white pollution" caused by waste plastics, bioplastics have attracted widespread attention from researchers due to their natural, environmentally friendly and renewable properties. Bioplastics refer to plastics prepared on the basis of natural biomass materials such as starch. They are high-molecular substances that have excellent performance during use and can be rapidly decomposed by enzymes or microorganisms after use. Bioplastics developed from starch not only effectively control "white pollution", but also can replace petroleum-based plastics, and the cost is only 1 / 5 of that of petroleum-based plastics. Developed countries such as Germany, Austria, the Netherlands, the United States, Italy, and Japan have l...
