Description

technical field [0001] The invention relates to the technical field of 3D printing materials, in particular to a 3D printing material for agricultural pesticide coating with high slow-release properties. Background technique [0002] 3D printing materials are an important material basis for the development of 3D printing technology. To a certain extent, the development of materials determines whether 3D printing can be used more widely. At present, 3D printing materials mainly include engineering plastics, photosensitive resins, and rubber materials. , metal materials and ceramic materials. 3D printing materials are widely used, and are also used in coated fertilizers and coated pesticides in agriculture. However, the slow-release performance of 3D printed materials for agricultural pesticide coatings in the prior art cannot meet the needs of the actual planting process. Therefore, There is an urgent need to develop a 3D printing material for agriculture with high sustained...
