Enhanced fully biodegradable material and preparation method thereof

Abstract

The invention relates to an enhanced fully biodegradable material and a preparation method thereof. The enhanced fully biodegradable material is prepared from the following raw materials in parts by weight: 61-69.5 parts of polyhexamethylene terephthalate, 27-30 polylactic acid, 0.5-1 part of a carbon nano tube and 2-8 parts of a coupling reagent. According to the fully biodegradable material, through adding a proper amount of the carbon nano tube, a prepared fully biodegradable material has excellent mechanical properties, and is good in film-forming property; a prepared film has high tensile strength and high elongation rate; compared with a film prepared from a common fully biodegradable material, the tensile strength and the elongation rate of the film prepared from the fully biodegradable material provided by the invention can be improved by over 50%. In addition, the fully biodegradable material can be quickly degraded into carbon dioxide, water, humus and the like, and does not cause pollution to the environment.

Description

technical field [0001] The invention relates to the technical field of degradable materials, in particular to an enhanced fully biodegradable material and a preparation method thereof. Background technique [0002] As a cheap and high-quality material, plastic is widely used in packaging materials and disposable products. However, the long-term use of plastic products in large quantities has seriously polluted the environment and caused severe white pollution. As we all know, the ecological disaster caused by white pollution has become one of the major problems plaguing the survival and development of human beings in the 21st century. [0003] In order to reduce white pollution and protect the ecological environment, the research, development and use of degradable materials are particularly important. At present, the commonly used biodegradable plastics are polylactic acid, polybutylene succinate, polybutylene adipate terephthalate, polybutylene adipate succinate, polycapr...

AI Technical Summary

Problems solved by technology

However, although this type of biodegradable has good physical and mechanical properties, compared with films made of ordinary polyethylene materials of the same thickness, its tensile strength and elongation are relatively small; in order to meet different actual needs, people The method of increasing the thickness of degradable materials is generally used to improve its mechanical properties
