Abstract
The invention provides a preparation process of a cellulose packaging film. The packaging film is mainly made from cellulose which can be completely biodegraded and is non-toxic. The degradable cellulose packaging film replaces a synthesized plastic film, recovery and treatment procedures are simplified, and the cellulose packaging film contributes to environmental protection. According to the preparation process of the cellulose packaging film, the processing steps are simple, and the prepared cellulose packaging film has high mechanical strength and is easy to degrade.
Description
Technical field
The present invention relates to a kind of packing film preparation technology, particularly relate to a kind of Mierocrystalline cellulose packing film preparation technology.
Background technology
Cellulose resource is enriched, and is environment-friendly material, and cellulose and its derivates has quite long history as masking starting material, has been widely used in the fields such as plastics, weaving, papermaking, food, daily use chemicals, medicine, building and biology.Play a part very important in film producing industry.Particularly recent years, various high-performance, functional fiber element film emerges in an endless stream, and is a focus in Cellulose Science research.Modal cellulose and its derivates film has the ester class film of the cruel class film of Mierocrystalline cellulose, Mierocrystalline cellulose acids film and ether of cellulose.
Summary of the invention
The invention provides a kind of Mierocrystalline cellulose packing film preparation technology, it is characterized in that, described processing step is:
(1) preparation of ionic liquid: n-propylcarbinyl chloride and N-Methylimidazole are mixed with the ratio of 2:1 row, put into ultrasonic wave afterwards to vibrate 15-20min, after completing, its temperature is risen to 90-95 DEG C and is aided with stirring and condensing reflux by heating in water bath, until no longer dropping liquid, reaction completes, for subsequent use;
(2) ionic liquid pin slurries and step (1) prepared is according to the ratio row mixing of 2:3, swelling at 70-80 DEG C after mixing, afterwards temperature is risen to 90-95 DEG C, obtain cellulose gel, by cellulose gel striking film forming on a glass, put into precipitation bath to be separated, obtain cellulose membrane packing film.
Preferably, the frequency control of the middle sonic oscillation of described step (1) is at 100-120Hz.
Preferably, in described step (2), swelling time controls at 8-10h.
Beneficial effect: the invention provides a kind of Mierocrystalline cellulose packing film preparation technology; the main raw material of this packing film is Mierocrystalline cellulose; Mierocrystalline cellulose fully biodegradable, nontoxic; synthetic plastic film is replaced to use with Mierocrystalline cellulose degradable film for package; simplify recovery and handling procedure, for contribution has been made in environment protection.Mierocrystalline cellulose packing film preparation technology provided by the invention, its processing step is simple, and the Mierocrystalline cellulose packing film physical strength simultaneously produced is high, easily degrade.
