3D printing silk material and preparation method thereof

The present invention relates to the blend 3D printing silk material of a kind of thermoplastic cellulose, Microbe synthesis polyester, reactive monomer and initiator, it is high mainly to solve thermoplastic cellulose low temperature process process medium viscosity in the prior art, product poor toughness, and make it be difficult to apply the technical problem in 3D printing field.The present invention is by using 3D printing silk material, and thermoplastic cellulose and Microbe synthesis polyester blend containing graft modification, in terms of mass fraction, thermoplastic cellulose and the Microbe synthesis polyester blend of the graft modification include following components：1) 20 to 80 parts of thermoplastic cellulose；2) 80 to 20 parts of Microbe synthesis polyester；3) 0.1 to 10 part of reactive monomer；It is characterized in that reactive monomer is at least grafted to thermoplastic cellulose and the technical solution on Microbe synthesis polyester one in the blend, preferably solves the problems, such as this, in the industrial production available for biodegradable 3D printing silk material.
