Abstract

The invention relates to a polymer material used for 3D printing. The polymer material comprises polyurethane acrylate, epoxy resin, ethyl cellulose, polyethylene wax, wollastonite powder, hydrogenated abietinol, epoxy acrylate, 2-hydroxy-4-methoxybenzophenone, trioctyl trimellitate, dipropylene glycol diacrylate, benzidine, polyoxyethylene laurate, nano-nickel oxide, poly(butyl acrylate), trimesic acid, isodecyl acrylate, barium stearate and calcium stearate. The prepared material has higher tensile strength and tensile modulus, retains good toughness, has good performance indexes, such as elongation at break and impact strength, not only has rather high toughness but also has higher heat resistance and good usability.

Description

technical field [0001] The invention relates to a polymer material for 3D printing and a preparation method thereof, belonging to the technical field of 3D printing materials. Background technique [0002] As an important structural material, some polymer materials (polyether ether ketone, polyimide, etc.) have the advantages of high strength, high hardness, wear resistance, and corrosion resistance. It has a wide range of applications in many fields. However, for polymer parts with complex shapes, complex molds are required to shape them. However, complex molds require high manufacturing costs and a long manufacturing cycle. At the same time, once the mold is manufactured, the size, shape and other parameters of the polymer product cannot be modified, which restricts the prototype and Production of small batches of polymer parts. In today's increasingly fierce market competition and faster product updates, this production situation has become increasingly unable to meet ...
