Abstract

The invention discloses a rush medulla junci modification-based 3D printer base material and a preparation method thereof. The preparation method comprises the following steps: (1) performing fixation and smashing on rush medulla junci, then mixing rush medulla junci powder with bamboo charcoal powder and soaking into a mixed solution of 1-naphthylamine and hydrochloric acid, and then filtering to take a filter cake to prepare a modified composition; (2) mixing expanded polystyrene, the modified composition, polyacrylonitrile, polychloro trifluoroethylene, silica, 2-sulfhydryl phenylthiazole, dilauryl thiodipropionate, steel fibers, mica powder, dioctyl adipate and zinc borate, and then fusing, cooling and pelleting to prepare the 3D printer base material. The 3D printer base material prepared through the method has excellent shock resistance and ageing resistance.

Description

technical field [0001] The invention relates to a base material for a 3D printer, in particular to a modified rush-based base material for a 3D printer and a preparation method thereof. Background technique [0002] The 3D printer base is one of the more important components in the 3D printer. The 3D printer base only needs to play the role of support and load-bearing. In actual production, the requirement for the 3D printer base is to have excellent stability and mechanical properties. [0003] At present, the 3D printer base can be divided into metal base and polymer base according to the material. Although the metal base has strong mechanical properties, the cost of the metal base is high. Although the cost of the polymer base is relatively cheap, the mechanical properties and anti-aging aspects of the polymer base are poor, which greatly affects the application of the polymer base in 3D printers. Contents of the invention [0004] The purpose of the present inventio...
