Abstract

The invention provides a starch-filled PLA / PBAT full-biodegradable composite material and a preparation method thereof, and belongs to the field of high polymer materials. A purpose of the invention is to solve the problems of poor toughness, brittleness and easy breaking of polylactic acid and the technical problems of difficult processing of starch, poor compatibility with PLA / PBAT resins and the like. The starch-filled PLA / PBAT full-biodegradable composite material comprises, by weight, 5-90 parts of polylactic acid, 10-90 parts of polyadipic acid / butylene terephthalate, 10-50 parts of starch, 2-15 parts of a plasticizer, 0.1-5 parts of a coupling agent, 0.1-0.5 part of a dispersing agent, 0.1-1 part of a compatibilizer and 0.1-0.5 part of an antioxidant. According to the invention, thepreparation method can be applied to preparation of starch-filled PLA / PBAT full-biodegradable composite materials.

Description

technical field

[0001] The invention belongs to the field of polymer materials, in particular to a starch-filled PLA / PBAT fully biodegradable composite material and a preparation method thereof. Background technique

[0002] At present, the production development and demand scale of polymer materials are growing rapidly, and the consumption field is expanding. Plastics are gradually replacing various materials and playing an important role in all aspects of our lives. "Replacing steel with plastic and wood with plastic" is more It is a big trend. Therefore, the development and manufacture of environmentally friendly fully biodegradable polymer materials has considerable economic and environmental value in today's global warming and reduction of oil resource reserves.

[0003] Polylactic acid (PLA) is a lactic acid monomer formed by microbial fermentation of biomass raw materials. It is a polymer material formed by condensation polymerization or ring-opening polymerization o...
