Abstract

The invention discloses a polyglycerol-fatty-acid-ester-containing antifogging degradable plastic film composite material and a preparation method thereof. The invention is characterized in that the composite material is prepared from starch, polyvinyl alcohol, urea, glycerol, L-proline, NaOH, nano TiO2, manganese stearate, kaolin, chitosan, sodium carboxymethyl cellulose, attapulgite, graphene oxide, polyethyleneimine, vinyl acetate, acrylic acid, hydroxyethyl methacrylate, polyglycerol fatty acid ester and the like. Proline sodium is utilized to modify the nano TiO2 to prepare the composite catalyst; the kaolin is used as a bioactivator; and the manganese stearate is used as a degradation accelerator, thereby preparing the biodegradable composite film. The sodium carboxymethyl cellulose is added and blended with the attapulgite and chitosan to prepare the composite material. The vinyl acetate is utilized to modify the starch, and electrostatic bonding force exists between the graphene oxide and polyethyleneimine, thereby enhancing the barrier property of the composite film, and lowering the oxygen permeability.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to an anti-fog degradable plastic film composite material containing polyglycerol fatty acid ester, and a preparation process thereof. Background technique [0002] In order to protect the environment and alleviate the shortage of petroleum resources, the use of petroleum-based plastic materials should be reduced, and bio-based degradable and environmentally friendly plastic materials should be developed and utilized. Biodegradable materials have excellent biocompatibility and environmental friendliness, and become The focus of research in the field of packaging materials. [0003] Cong Hongjie used starch (St) and polyvinyl alcohol (PVA) as the main raw materials in his master's degree thesis "Preparation and Thermal Decomposition Kinetics of Degradable Plastic Films", adding urea (crosslinking agent), glycerin Alcohol (plasticizer), the St / PVA completely biodegradable plastic f...
