Abstract

The invention provides a novel visible light-initiated photoinitiator composition for a 3D printing technology. The visible light-initiated photoinitiator composition comprises a main photoinitiator and an assistant photoinitiator, wherein the weight ratio of the main photoinitiator to the assistant photoinitiator is 1:(0.1-10), preferably 1:(0.2-2), the main photoinitiator is an iodonium salt compound or a sulfonium salt compound or an arbitrary mixture of the iodonium salt compound and the sulfonium salt compound; the assistant photoinitiator has a structural formula shown in a formula (I),wherein in the formula (I), R is one or more selected from H, Cl, Br, I and NO2, and M is one or more selected from H, Na, K, Li and NH4. The photoinitiator composition is applicable to a photo-curingmaterial in a photo-curing 3D printing forming technology, rapid curing molding of the material can be initiated through excitation of a visible light source, and the photoinitiator composition has the advantages of high initiation efficiency, good stability, high safety performance and the like.

Description

technical field [0001] The invention relates to the technical field of material engineering, in particular to a photoinitiator composition initiated by visible light for 3D printing technology and its application. Background technique [0002] 3D (three-dimensional) printing technology, as an emerging technology in the field of rapid prototyping, is called "manufacturing technology with industrial revolution significance". The main process of using this technology for production is: first use computer software to design a three-dimensional processing pattern, and then use specific molding equipment (commonly known as "3D printer") to add materials layer by layer with liquefied, powdered, etc. solid materials to generate product. It is different from the traditional material removal processing technology, so it is also called additive manufacturing, also known as additive manufacturing or incremental manufacturing. [0003] The 3D printing manufacturing process is short, fu...
