A kind of nano-cellulose base pen core ink and preparation method thereofTechnical field
The invention belongs to pen core inks fields, more particularly to a kind of nano-cellulose base pen core ink and preparation method thereof.
Background technique
It is environmentally protective reproducible both to have possessed fiber as a kind of novel biomass based high molecular material for nano-celluloseFeature, while but also with many other excellent performances such as nano material scale effect, special rheological characteristic, good dispersibilities.It is widely studied and is applied in various fields such as biologic medical, food safety, fine chemistry industry and composite materials.And in pen row processedIn industry, because of the complicated ingredients such as pigment, dispersing agent, viscosity modifier in pen core ink containing Nano grade, these are organicThe potential interaction of reagent keeps ink system unstable, causes the research and development of the especially colored pen core ink of pen core ink difficult,Preparation process is complicated.If nano-cellulose is applied in the preparation of pen core ink, because itself just has good streamDenaturation and dispersibility can then reduce even without using organic dispersing agent, viscosity modifier etc., can substantially reduce inkPreparation difficulty, and because nano-cellulose green renewable performance, the ink prepared have the good feature of environmental protection.
