Abstract

The invention provides poly(phenylene sulfone) composition for 3D printing. The poly(phenylene sulfone) composition is characterized in that the poly(phenylene sulfone) composition is graphite and silicone powder modified powder and comprises components in parts by weight as follows: 100 parts of poly(phenylene sulfone) resin, 10-20 parts of a solid flowable agent, 2-10 parts of a surfactant, 1-10 parts of a reinforcing agent, 1-5 parts of inorganic filler and 0.1-1 part of a leveling agent. Materials are dried by a vacuum drying box, solids and a liquid in a container are mixed and stirred and mixed uniformly at a high speed, and the powdery poly(phenylene sulfone) composition with uniform granularity, good flowability and excellent mechanical performance is obtained after centrifugal drying and has wide prospect in the field of 3D printing materials.

Description

technical field [0001] The invention relates to the field of 3D printing technology polymer materials, in particular to a polyphenylsulfone composition for 3D printing and a preparation method thereof. Background technique [0002] Three-dimensional (3D) printing, which emerged in the mid-1990s, is actually the latest rapid prototyping device utilizing technologies such as light curing and paper lamination. 3D printing technology is also known as additive manufacturing technology. The basic principle is stacked manufacturing, which is a technology that increases materials layer by layer to generate three-dimensional entities. It is actually an emerging technology in the field of rapid prototyping. It is a digital model file-based , the technology of constructing objects by layer-by-layer printing using bondable materials such as powdered metal or plastic. At present, 3D printing technology is mainly used in product prototyping, mold manufacturing, artistic creation, jewelry...
