Abstract

The invention discloses modified polyphenylene sulfide resin suitable for 3D printing. The modified polyphenylene sulfide resin is a combination of the following components in parts by weight: 65-85 parts of polyphenylene sulfide resin, 0.05-0.6 part of a chain extender, 0.5-1 part of an end capping agent, 0.1-0.7 part of a crosslinking agent, 3-20 parts of low-molecular-weight polymer, 2-10 parts of a toughening agent, 1-5 parts of a reinforcing agent, 1-6 parts of a lubricating agent and 0.1-0.7 part of a heat stabilizer. The polyphenylene sulfide resin is modified by adopting the simple processes of mixing materials and extruding, and the processing temperature of the modified polyphenylene sulfide resin is reduced greatly. The melting temperature of the device formed by printing by adopting the modified polyphenylene sulfide resin is not reduced significantly, and the toughness is improved, and thus the polyphenylene sulfide resin can be widely applied to the field of 3D printing.

Description

technical field [0001] The invention relates to a material suitable for 3D printing and its preparation method and application, in particular to a modified polyphenylene sulfide resin material suitable for 3D printing and its preparation method and application. Background technique [0002] 3D printing technology, also known as additive manufacturing technology, is actually an emerging technology in the field of rapid prototyping. It is based on digital model files and uses bondable materials such as powdered metal or plastic. A technique for constructing objects in a manner. The basic principle is additive manufacturing, the technique of adding material layer by layer to generate a three-dimensional solid. At present, 3D printing technology is mainly used in product prototyping, mold manufacturing, art creation, jewelry making and other fields, replacing these traditional fine processing techniques. In addition, 3D printing technology is gradually applied in fields such a...
