| titleOfInvention | A kind of method of modifying of plant fiber |
| abstract | The present invention relates to the preparation methods of a kind of polymer graft modification plant fiber and/or nano-cellulose, use the aqueous solution of plant fiber magma, and/or person's nano-cellulose for dispersion liquid；Ethyl alcohol, sodium hydroxide are added into dispersion liquid, makes fiber surface part that quaternization occur；It is reacted monochloroacetic acid is added in the plant fiber and/or nano-cellulose of above-mentioned surface portion basification, obtained fiber surface contains the plant fiber or nano-cellulose of carboxymethyl；The carboxymethylated plant fiber in above-mentioned part is subjected to graft reaction by grafting agent and water-soluble polymer, water-soluble polymer modified plant fibers or nano-cellulose is made.Grafting water polymer and oil-soluble polymers are carried out to fiber surface, while not changing plant fiber and cellulose crystallite fascicular texture, different types of polymer of grafting assigns modified plant fibers and the good dispersibility of cellulose and cementability, expands plant fiber and nano-cellulose multiple use. |
