Abstract

The invention discloses a production method of a high-tenacity 3D printing material, and belongs to the technical field of environment-friendly novel materials. According to the production method of the high-tenacity 3D printing material, konjaku flour and sodium carboxymethylcellulose components are compounded, N-methyl pyrrolidone with a cross-linking effect is added to improve the dispersion performance of graphene, the mechanical performance of the obtained material can be supplemented and improved, the tensile property is improved, and the tenacity of the material is ensured, so that theevenness and the tenacity of the 3D printing material are improved. According to the production method of the high-tenacity 3D printing material, modification treatment is conducted on sepiolite, sulfhydryl groups are grafted onto the surfaces of the sepiolite, by means of the character of the sepiolite that the sepiolite is soft in the presence of water and dry without water, the uniformity of the material can be improved, and by controlling large adding amount, application effects of the material can be stably improved. By adopting size compounding and cross-linking modification of components of the graphene and the like, the dispersion performance and the tenacity of the material are stably improved, and group modification is conducted on the sepiolite, so that the application effects of the material are further improved. By means of the production method of the high-tenacity 3D printing material, the problem that currently, common 3D printing materials are poor in evenness and tenacity is solved.

Description

technical field [0001] The invention belongs to the technical field of environmentally friendly new materials, and in particular relates to a preparation method of a high-toughness 3D printing material. Background technique [0002] 3D printing is a technology that is quite different from traditional manufacturing technologies such as subtractive manufacturing and equal material manufacturing. Based on the three-dimensional data of the model, the material is extruded through the printer nozzle, and the material is added layer by layer to generate a 3D entity. Therefore, Also known as additive manufacturing (additive manufacturing), it includes many cutting-edge technologies, such as: modeling technology, electromechanical control technology, information technology, material science, etc. 3D printing, also known as additive manufacturing, is a systematic and comprehensive emerging technology that combines computer software, materials, machinery and other fields. entity.
