Agricultural 3D printing material

Abstract

The invention provides an agricultural 3D printing material. The agricultural 3D printing material is prepared from raw materials in percentage by weight as follows: 40%-50% of modified polylactic acid, 0.1%-1% of nitrile rubber, 0.1%-3% of an ethylene-vinyl acetate copolymer, 0.1%-3% of ethylene acrylic acid grafted maleic anhydride, 0.1%-3% of a surfactant and 40%-60% of phenolic resin. The agricultural 3D printing material has the characteristics of good toughness, high hardness and long service life.

Description

technical field [0001] The invention belongs to the technical field of material science, and in particular relates to an agricultural 3D printing material. Background technique [0002] Three-dimensional printing technology is an emerging manufacturing technology that developed rapidly at the beginning of this century, and it is called "manufacturing technology with industrial revolution significance". This technology is a kind of material rapid prototyping technology, also known as additive manufacturing. 3D printing technology can be summarized as: cut the 3D model made by software design or instrument scanning into infinite multi-layer sections according to a certain coordinate axis, and then use a 3D printer to print out layer by layer materials, and press the original Positions are stacked together to form a 3D entity. 3D printing technology has been widely used in product prototypes, mold manufacturing, artistic creation, jewelry making, bioengineering and medicine, ...

AI Technical Summary

Problems solved by technology

However, the mechanical properties of pure polylactic acid cannot meet the needs of use, and the polylactic acid used in printing materials needs to be strengthened and modified. Therefore, it is urgent to design a 3D printing material with excellent toughness and hardness for agriculture to solve the problem. Problems in the prior art
