Synthesis process of degradable biopolymer material

Abstract

The invention discloses a synthesis process of a degradable biopolymer material, and relates to the technical field of synthesis of degradable biopolymer materials, in particular to a synthesis process of a degradable biopolymer material. The degradable biopolymer material is prepared from the following components in parts by weight: 40-50 parts of degradable macromolecules, 30-40 parts of epoxy resin, 10-20 parts of unitary phthalamide resin, 15-25 parts of lactide, 10-20 parts of lactic acid, 6-10 parts of talcum powder, 4-8 parts of a coalescing agent, 3-5 parts of a catalyst, 1-3 parts ofa modifier, 2-5 parts of a thickener, 1-2 parts of a compatilizer, 3-5 parts of a coupling agent, 2-3 parts of a flexibilizer and 1-5 parts of a bactericide. According to the synthesis process of thedegradable biopolymer material, the coalescing agent can promote plastic flow and elastic deformation of a polymer compound, improve coalescence performance, form a film in a wide construction temperature range, the catalyst can effectively promote the mixing efficiency of raw materials, and the thickener can effectively increase the mixing concentration of the raw materials; and the raw materialmixing uniformity is improved.

Description

technical field [0001] The invention relates to the technical field of synthesis of degradable biopolymer materials, in particular to a synthesis process of degradable biopolymer materials. Background technique [0002] People have deeply studied the biodegradability of different biodegradable polymer materials, and found that it has a great relationship with its structure, including chemical structure, physical structure, surface structure and so on. The chemical structure of polymer materials directly affects the strength of biodegradability, in general: aliphatic ester bond, peptide bond > carbamate > aliphatic ether bond > methylene. When the solid state structure of the same material is different, the degradation speed of different aggregation states is in the following order: rubber state > glass state > crystalline state. Generally, polymer materials with high polarity can adhere to the enzyme phase and have a good affinity. The way microorganisms adhe...
