Problems solved by technology

However, the current research has not yet solved the following problems: (1) The existing processes and technologies cannot realize the homogeneous composite of cellulose and polylactic acid (uniformly mixed in a molecular state), and the polylactic acid and cellulose in the composite material are in a phase-separated state ( Mixed in a solid state, the two are mixed unevenly), resulting in very limited performance improvement of the composite material, or even performance degradation (for example, material curling deformation, uncontrollable shape, tensile strength reduction, etc.); (2) cellulose / The amount of polylactic acid in polylactic acid composite materials is too high, some are as high as 90-95%, and the cost is still high. Compared with petrochemical-based plastics, it is far from being competitive, and its large-scale application is still limited

Abstract

The invention relates to the technical field of high molecular materials, in particular to tetrabutylammonium methoxyacetate, a cellulose / polylactic acid composite material and the application thereof. The tetrabutylammonium methoxyacetate adopts a structural formula shown as a formula I. The tetrabutylammonium methoxyacetate is obtained by dropwise adding methoxyacetic acid into an aqueous tetrabutylammonium hydroxide solution, then reacting while stirring, and removing impurities; through compounding of the tetrabutylammonium methoxyacetate and an aprotic solvent DMF, cellulose and polylactic acid can be uniformly mixed in a molecular state to obtain the cellulose / polylactic acid composite material; in the cellulose / polylactic acid composite material, the cellulose and the polylactic acid are uniformly mixed in the molecular state, so that the performance, including the tensile strength and the biodegradability, of the composite material is significantly improved; a practicable technical route is provided for preparation of environment-friendly and biodegradable plastic products, fiber, medical supplies and the like.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to tetrabutylammonium methoxyacetate, cellulose / polylactic acid composite material and its application. Background technique [0002] In the process of the development of human society, fossil energy has created a splendid modern civilization, but in terms of deteriorating the earth's environment and putting human beings in danger of survival, fossil energy and its derivatives are the chief culprits. Therefore, the Chinese government proposes the goal of replacing fossil energy with non-fossil energy by the end of this century. There are two main ways to achieve this goal. One is to replace fossil energy with renewable energy; the other is to replace fossil energy derivatives represented by plastics and fibers with green and environmentally friendly products. According to the current status, among various biodegradable polymer raw materials, cellulose and polylactic acid ...
