The invention provides an additive manufacturing rapid prototyping furan resin and a preparation method thereof, belonging to the field of polymer materials, and aims to provide a resin with uniform molecular weight distribution, low moisture, moderate viscosity, low electrical conductivity, fast curing and forming, and high strength The preparation method of the furan resin is used to meet the current stage of 3D printing inkjet resin modeling. By mass fraction of 95-97% paraformaldehyde 5-8%, resorcinol 5-10%, tert-butylphenol 1-5%, bisphenol A 5-10%, furfuryl alcohol A30-50%, furfuryl alcohol B10 ～30%, furfuryl alcohol C10～30%, 5-hydroxymethyl furfural or 5-acetoxymethyl furfural 1～5%, 2,5-furandimethanol 1～5% and other components are modified and prepared to obtain Each performance is superior to the resin materials of 3D printing technology currently available on the market, realizing the substitution of imported resins. |
