Abstract

The invention discloses a chitin reinforced PGA-PLA composite material with a controllable degradation period as well as a preparation method and application thereof. The composite material comprises the following components in parts by weight: 10-50 parts of polyglycolic acid (PGA), 50-90 parts of polylactic acid (PLA), 2-15 parts of a toughening agent, 0-1 part of a hydrolysis-resistant agent and 10-40 parts of carapace powder. The composite material disclosed by the invention not only has excellent processability and mechanical property, but also has a controllable degradation period, so that the composite material can be used in fields with corresponding requirements on the degradation period.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and specifically relates to a chitin-reinforced PGA-PLA composite material with a controllable degradation period, a preparation method and an application thereof. Background technique [0002] Biodegradable plastics, also known as biodegradable plastics, refer to the action of microorganisms existing in nature under natural conditions such as soil and / or sandy soil, and / or under specific conditions such as composting conditions or anaerobic digestion conditions or in aqueous culture fluids. cause degradation, and eventually complete degradation into carbon dioxide (CO 2 ) or / and methane (CH 4 ), water (H 2 O) and mineralized inorganic salts of the elements it contains and plastics from new biomass. Among them, the degradable materials used include PGA, PLA and PLGA. [0003] PGA (polyglycolic acid), a green and environmentally friendly material with excellent biodegradability and a...
