Abstract

The invention discloses a biodegradable and toughened composite material and a preparation method thereof, belonging to the field of material technology, and comprises modified carbon nanotubes, polylactic acid, polyadipate / butylene terephthalate and di-( tert-butylperoxycumyl) benzene is used as a raw material, and the biodegradable toughened composite material is obtained through extrusion injection molding. Among them, the acidified carbon nanotubes are treated with a silane coupling agent to improve the dispersion of conventional carbon nanotubes and the bonding with the matrix, and the use of di-(tert-butylperoxyisopropyl)benzene can improve Compatibility of polylactic acid and polybutylene adipate / terephthalate. The preparation method of the biodegradable toughened composite material of the present invention is simple, the toughness is greatly improved, and can be applied to the fields of automobiles, packaging, electronics, aerospace and the like.

Description

technical field

[0001] The invention belongs to the technical field of materials, and in particular relates to a biodegradable toughened composite material and a preparation method thereof. Background technique

[0002] Polylactic acid (PLA) is a biodegradable and environmentally friendly material derived from starch extracted from plants (corn, cassava, sugar beet, etc.). Polylactic acid can be degraded in a humid environment or in a microbial environment, and produces water and carbon dioxide that are not harmful to the environment. However, polylactic acid has poor toughness, plasticity and heat resistance, which limits its application in many aspects.

[0003] Polybutylene adipate / terephthalate (PBAT) is a biodegradable material synthesized from petrochemical products. It has good ductility, heat resistance, and toughness, but low strength and low modulus. The mechanical properties of polylactic acid and polyadipate / terephthalic acid diester are completely opposite, so...
