Abstract

The present invention discloses a 3D printer base material based on phyllostachys heteroclada oliver modification, and a preparation method thereof. The preparation method comprises: 1) deactivating phyllostachys heteroclada oliver, grinding, mixing the phyllostachys heteroclada oliver powder and bamboo charcoal powder, soaking the obtained mixture in a morpholine and hydrochloric acid mixing solution, and filtering to obtain filter cake so as to prepare a modified composition; and mixing polyisobutylene, the modified composition, polyacrylonitrile, polybutadiene, titania, isobutyl triethoxy silicon, tetramethylthiuram disulfide, steel fibers, sepiolite powder, dioctyl adipate and zinc borate, melting, cooling, and granulating to prepare the 3D printer base material. According to the present invention, the 3D printer base material prepared through the method has excellent impact resistance and excellent aging resistance.

Description

technical field [0001] The invention relates to a 3D printer base material, in particular to a water bamboo-based modified 3D printer base material 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 object of the present invention is ...
