Abstract

The invention discloses a high-strength regenerated nanocellulose mixed film production method. The method is characterized by including steps of preparation of dissolving pulp, preparation of high-concentration nano mixed dissolving pulp, preparation of nano mixed dissolving pulp, preparation of a regenerated nanocellulose mixed film and preparation of a finished product. The method is a novel high-strength regenerated nanocellulose mixed film production method in which NMMO hydrate serves as a solvent, and problems of fibrillation, high defects, instable product quality and the like of cellulose films prepared according to an NMMO method are solved while appearance, strength and performances are all optimized.

Description

technical field [0001] The invention relates to the technical field of production and preparation of mixed membranes, in particular to a production method of high-strength regenerated nanocellulose mixed membranes. Background technique [0002] Cellulose comes from plants and is the most abundant renewable resource on earth. Making full use of cellulose can not only protect the environment, but also save limited petroleum resources. The existing methods of manufacturing cellulose film are mainly viscose method and solvent method. Among them, a large amount of carbon disulfide will be produced in the manufacturing process of the viscose method to cause environmental pollution, and the residual sulfur content of the cellulose film of the viscose method is relatively high, so it is not suitable for food packaging materials that are required to be completely non-toxic to the human body, especially in In the state of high temperature heating. [0003] The solvent method is that...
