Title:
MICRO-NANO LIGNOCELLULOSE, PREPARATION METHOD THEREOF AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/141140
Kind Code:
A1
Abstract:
The present invention discloses a micro-nano lignocellulose, a preparation method thereof and an application thereof. The micro-nano lignocellulose comprises a lignin structure, in which the lignin is combined with cellulose in the form of a hydrogen bond and a chemical bond. The preparation method of the micro-nano lignocellulose is as follows. A lignin-containing cellulose raw material is dispersed in an organic solvent, a hot urea aqueous solution, or water at a temperature of at least 50 °C, so as to obtain a cellulose raw material dispersion liquid. Peeling and grinding are performed by means of mechanical pretreatment to obtain a pretreated product. The pretreated product is subjected to high-pressure homogenization by using a high-pressure homogenizer, thereby obtaining a micro-nano lignocellulose dispersion liquid.
