Embodiment 1

[0025] 160g of microcrystalline cellulose wet cake with a particle size of 30-50nm was placed in a mixer with 15g of medium-viscosity carboxymethyl cellulose after ultrasonic treatment at 200 watts for 12 minutes. The proportion of solids forming the mixture is: 50 parts by weight of nanocrystalline cellulose, and 15 parts by weight of carboxymethyl cellulose. Turn on the mixer until the composition is homogeneously mixed. Then dry and crush to get the finished product.

Embodiment 2

[0027] 150g of microcrystalline cellulose wet cake with an average particle size of 55nm was placed in a mixer with 72.5g of KAPPA type I carrageenan after ultrasonic treatment at a power of 200 watts for 10 minutes. The solid proportion of the mixture is: 50 parts by weight of nano-microcrystalline cellulose, and 72.5 parts by weight of KAPPA type I carrageenan. Turn on the mixer until the composition is evenly mixed. Then dry and crush to get the finished product.

Embodiment 3

[0029] 100g of microcrystalline cellulose wet cake with an average particle size of 65nm was placed in a mixer with a mixture of 15g of carboxymethyl cellulose and hydroxypropyl starch after ultrasonic treatment of 200 watts of power for 8 minutes. The solid ratio of the mixture is: 50 parts by weight of nanocrystalline cellulose, 7 parts by weight of carboxymethyl cellulose, and 8 parts by weight of hydroxypropyl starch. Turn on the mixer until the composition is evenly mixed. Then dry and crush to get the finished product.

Abstract

The nanometer microcrystal cellulose powder is surface modified nanometer microcrystal cellulose with added hydrophilic colloid in the amount of 5-150 wt% of nanometer microcrystal cellulose and has grain size of 6.3-100 nanometers. During its preparation, hydrophilic colloid is dispersed homogeneously into water dispersed medium of surface modified nanometer microcrystal cellulose and the mixture is then dried and crushed. The nanometer microcrystal cellulose is easy to be water dispersed to form colloid, which is homogeneous and high in gluing strength and has the small size of microcrystal cellulose maintained, so that it has wide and unique application foreground in food production, medicine, papermaking, textile, new material preparation and other fields.

Description

technical field [0001] The invention relates to an easily water-dispersible nano-microcrystalline cellulose powder, a preparation method thereof and a colloid formed from it. technical background [0002] Cellulose is the most extensive, inexhaustible and inexhaustible renewable resource that exists in nature. After the crisis of non-renewable energy sources such as petroleum on the earth, degrading and further processing cellulose to obtain chemical raw materials and intermediates has always been a research hotspot in various countries. [0003] Ultrafine and nano cellulose crystals have a wide range of uses, and can be used as additives and fillers in the fields of food and medicine, and can also be used as raw materials in the preparation of new materials. [0004] In the Chinese invention patent application (application number 00117261.1, application number 01107523.6), it has been disclosed that natural cellulose is used to prepare nanocellulose crystals with cellulose...
