Problems solved by technology

However, this post-processing method has a complicated process and limited functional effects
[0011]If conventional functional fillers are directly added to 3D printing materials, although the functional effect can be improved to a certain extent, there will be slurry settlement and 3D printing parts transparent. Problems such as poor luminosity

Embodiment 1

[0091] This example prepares a conductive 3D printing material. The specific raw material composition is shown in Table 1. The specific steps are as follows:

[0092] S1. After mixing the acrylic active diluent and dispersant, add the nano conductive filler three times (firstly mix the two nano conductive fillers evenly, and add the same mass each time), and grind; the grinding speed is 1000r / min, add the first time Grind for 20 minutes after the nano-conductive filler is added, grind for 40 minutes after adding the nano-conductive filler for the second time, and grind for 60 minutes after adding the nano-conductive filler for the third time. After the grinding is completed, the mixed solution A is obtained;

[0093] S2. Transfer the mixed liquid A to a double planetary stirring tank, add acrylate resin, and stir and mix for 30 minutes. During the stirring process, the shear speed is 4m / s, and the revolution speed is 0.3m / s. After the stirring is completed, the mixed liquid is ...

Abstract

The invention provides a conductive 3D printing material, and a preparation method and application thereof. The conductive 3D printing material is prepared from the following components in parts by mass: 60 to 90 parts of acrylate resin, 5 to 20 parts of an acrylic reactive diluent, 0.5 to 5 parts of a photoinitiator, 0.5 to 20 parts of a nanometer conductive filler and 0.5 to 2 parts of a dispersing agent. As needed, the conductive 3D printing material may also comprises 0-0.2 part of a fluorescent whitening agent and 0-2 parts of a pigment and other second fillers. The conductive filler adopted by the conductive 3D printing material is nano-sized, so the problem of sedimentation of the conductive filler in the storage and application processes of the conductive 3D printing material is relieved, and the problem of low light transmittance of a 3D part printed by the conductive 3D printing material is also relieved. The conductive filler is in a rod shape, a point shape, a sheet shape and the like, so a net-shaped conductive system with high conductivity can be formed, cost is finally reduced, conductivity is improved, and the sedimentation problem of the conductive filler is relieved.

Description

technical field [0001] The invention belongs to the field of 3D printing, and specifically relates to a conductive 3D printing material, a preparation method and an application. Background technique [0002] 3D printing, also known as additive manufacturing, is a type of rapid prototyping technology and is known as the core technology of the third industrial revolution. Materials are the foundation of 3D printing, and they are also the bottleneck restricting the development of 3D printing. 3D printing materials are specially developed for 3D printing equipment and processes. They are different from ordinary plastics, gypsum, resins, etc., and their forms generally include powder, filament, layer, and liquid. [0003] At present, 3D printing materials mainly include engineering plastics, photosensitive resins, rubber materials, metal materials and ceramic materials. In addition, food materials such as colored gypsum materials, artificial bone powder, cell biological materia...
