Problems solved by technology

[0003] In recent years, before the season of receiving corn, people have deeply felt the impact of smog, which has brought inconvenience to our daily life and travel.
my country is a large agricultural country, the price of corn production is relatively high, and corn stalks are rich in resources. However, corn stalks are incinerated in many areas, which not only pollutes the environment, but also causes a huge waste of resources.

Abstract

The invention discloses a preparation method of a 3D printing material containing corn straws, and relates to the field of novel materials. The preparation method of the 3D printing material containing corn straws comprises the steps of pretreatment of the corn straws, raw material mixing, extrusion and granulating, 3D printing and the like. According to the preparation method, the corn straws aresubjected to surface modification treatment, the compactness and stability of a middle material are improved, granules are dried, and then are smashed into fine granules for 3D printing, smoothness of the surface of the material is ensured, and the prepared material has good corrosion resistance, dimension stability and mechanical property.

Description

technical field [0001] The invention relates to the field of new materials, in particular to a method for preparing a 3D printing material containing corn stalks. Background technique [0002] In recent years, 3D printing, with its special additive manufacturing method, has developed rapidly in the fields of product prototyping, jewelry making, bioengineering and architectural engineering. The difference between 3D printing and traditional manufacturing methods is that it mainly uses computers to construct three-dimensional structure models and controls materials to form objects layer by layer under the instructions of computer codes to achieve additive manufacturing. [0003] In recent years, before the season of receiving corn, people have deeply felt the impact of smog, which has brought inconvenience to our normal life and travel. my country is a big agricultural country, the price of corn production is relatively high, and corn stalks are rich in resources. However, co...
