Abstract

The invention belongs to the field of a biodegradable high polymer material and particularly relates to a reinforcing, toughening and permeability-increasing master batch special for an ultrathin full biodegrade film. The master batch is prepared by taking poly-adipic acid / polybutylene terephthalate and a reinforcing, toughening and permeability-increasing agent as the main raw materials, is capable of keeping the processing smoothness of the ultrathin full biodegrade film, also is capable of guaranteeing the mechanical and optical properties and use stability of the ultrathin full biodegrade film product and is capable of greatly reducing the cost of the raw materials. The production process of the master batch is simple and is easily mastered; the acquired master batch is stable in property, is free from water, is capable of fully degrading and is high in dispersity; a ultrathin full biodegrade film being 4-6 microns can be blown in the manner of adding few master batches provided by the invention, so that a film sheet is easy to open in the blowing process of the ultrathin film and the processing stability is promoted.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a plastic masterbatch, in particular to a special reinforcement, toughening and anti-permeability masterbatch for an ultra-thin fully biodegradable film and a preparation method thereof. Background technique [0002] Plastic films play a huge role in daily life and industrial and agricultural production. However, most of the plastic films currently used are polyolefin films that are difficult to degrade in a short period of time or incompletely degradable polyolefin films that are added with starch and photodegradants. . The use of these film materials has caused "white pollution" of the environment and brought safety hazards to the sustainable development of human beings. Fully biodegradable film is made of completely biodegradable plastics through blow molding, casting or calendering. It can be completely decomposed by microorganisms. The final products of its degradation ...
