Resin-based biodegradable 3D printing material and preparation method thereof

Abstract

The invention discloses a resin-based degradable 3D printing material. The 3D printing material is prepared from the following components by weight: 40-50 parts of epoxy resin, 30-40 parts of hydroxyl acrylic resin, 12-18 parts of phenolic resin, 10-20 parts of bamboo-fiber-containing polylactate, 16-20 parts of microcrystalline wax, 6-8 parts of silk fibroin, 12-16 parts of filling fines, 6-10 parts of polyacrylamide, 0.6-1 part of a photoinitiator, 2-6 parts of a cross-linking agent and 0.2-0.4 parts of an auxiliary agent. With adoption of the technical scheme, the printing material based on the epoxy resin, the hydroxyl acrylic resin, the phenolic resin and bamboo-fiber-containing polylactate can be naturally degraded without environmental pollution, the biodegradation rate and photodegradation rate of the material are increased according to tests, and tensile strength and bending strength of the 3D printing material are also enhanced correspondingly.

Description

technical field [0001] The invention relates to the technical field of 3D printing materials and preparation methods thereof, in particular to a resin-based degradable 3D printing material and a preparation method thereof. Background technique [0002] 3D printing is a rapid prototyping technology, known as the core technology of the "third industrial revolution". The complex forging process can get the final product, which can realize structural optimization, material saving and energy saving in production. [0003] Materials are the material basis of 3D printing, and they are also the bottleneck restricting the development of 3D printing. At present, the materials used in 3D printing are all from industrial synthetic materials. After the printed products are discarded, the industrial chemically synthesized materials are difficult to photodegrade or biodegrade.

[0003] Materials are the material basis of 3D printing, and they are also the bottleneck restricting the development of 3D printing. At present, the materials used in 3D printing are all from industrial synthetic materials. After the printed products are discarded, the industrial chemically synthesized materials are difficult to photodegrade or biodegrade. The environment has caused a lot of pressure, making the development of 3D printing technology encounter a bottleneck. Therefore, we propose a resin-based degradable 3D printing material and its preparation method
