Kudzu root nanocellulose fiber-polylactic acid plastic film and preparation method thereof

Abstract

The invention discloses a kudzu root nanocellulose fiber-polylactic acid full-degradable plastic film. The kudzu root nanocellulose fiber-polylactic acid full-degradable plastic film is prepared from raw materials in parts by weight as follows: 0.01-2 parts of kudzu root nanocellulose fibers, 0.01-0.5 parts of polyethylene glycol, 0.01-1 part of a plasticizer, 1-3 parts of polylactic acid, 30-40 parts of an organic solvent, 0.01-2 parts of nano-titania, 0.01-2 parts of nanometer mullite powder and 0.005-0.1 parts of a coupling agent. Environment-friendly polylactic acid is taken as a matrix, and nanocrystal cellulose fibers prepared from kudzu root residues are taken as a reinforcing material of the polylactic acid full-degradable plastic film, so that the strength, the modulus, the barrier property and the like of the film can be improved; organic combination for a nanocrystal cellulose fiber, inorganic material and polylactic acid ternary system is realized technologically, and the multifunctional polylactic acid full-degradable plastic film material is prepared.

Description

technical field [0001] The invention belongs to the field of plastic product preparation, in particular to the preparation of a kudzu root nanocellulose fiber-polylactic acid fully degradable plastic film. Background technique [0002] With the continuous development of society and economy, plastics have become an indispensable material in people's lives. There are a wide variety of plastic products, which have indeed brought a lot of convenience to people's lives, but the "white" caused by the refractory plastic waste "Pollution" is becoming more and more serious, which poses a threat to the living environment of human beings and has aroused widespread concern around the world. Various countries have formulated corresponding laws and regulations to prohibit or restrict the use of non-degradable plastic products and packaging materials. In addition, the raw material for the preparation of traditional plastics is petroleum, which is a non-renewable resource and will eventuall...
