specific Embodiment approach 1

[0030] Specific implementation mode 1: This implementation mode is a kind of green environmental protection 3D printing wire rod, which consists of 40-60 parts of hemp stem particles, 20-35 parts of polylactic acid, 5-9 parts of shrub branch particles, 5 parts- It is prepared by 8 parts of quick-drying green leaves, 0.5-2 parts of maleic anhydride, 0.5-2 parts of antioxidant, 0.5-1.5 parts of plasticizer and 0.5-2 parts of other additives.

[0031] The advantage of this implementation mode:

[0032] 1. The green and environmentally friendly 3D printing wire prepared in this embodiment is a composite 3D printing wire, which makes full use of fast-growing herbaceous plants, as well as shrubs and some leaves that are not mature. Polylactic acid is also one of its components The core component, which is a degradable material;

[0033] 2. The proportion of degradable components of the green and environmentally friendly 3D printing wire prepared in this embodiment has reached more ...

specific Embodiment approach 2

[0037] Specific embodiment two: the differences between this embodiment and specific embodiment one are: the particle diameter of the hemp stem particles is 1 mm to 10 mm; the water content of the hemp stem particles is less than 8%; the hemp stem particles The granules are one of ramie stem granules, velvetleaf stalk granules and flax stem granules or a mixture of several of them. Others are the same as the first embodiment.

specific Embodiment approach 3

[0038] Specific embodiment three: the differences between this embodiment and specific embodiment one or two are: the particle diameter of the shrub branch particles is 1 mm to 10 mm; the water content of the shrub branch particles is less than 10%; The shrub branch particles are shrub branch particles with a lignocellulose content of more than 40%; the shrub branch particles with a lignocellulose content of more than 40% are one of holly branch particles, boxwood branch particles and fufangteng branch particles or a mixture of several of them. Others are the same as those in Embodiment 1 or 2.

Abstract

The invention relates to a printing wire, particularly a green environment-friendly 3D printing wire and a preparation method thereof. The invention aims to solve the problems of high manufacturing cost and environmental pollution since the existing 3D printing material is a nondegradable material. The green environment-friendly 3D printing wire is prepared from the following components in parts by weight: 40-60 parts of straw granule, 20-35 parts of polylactic acid, 5-9 parts of shrub branch granule, 5-8 parts of quick-drying green leaf, 0.5-2 parts of maleic anhydride, 0.5-2 parts of antioxidant, 0.5-1.5 parts of plasticizer and 0.5-2 parts of other assistants. The preparation method comprises the following steps: 1. weighing; 2. grinding and screening; 3. drying; 4. mixing; 5. granulating; 6. extruding; and 7. rolling and bundling to obtain the green environment-friendly 3D printing wire. The green environment-friendly 3D printing wire has the advantage of low cost, and achieves the goals of greenness, low carbon and environment friendliness. The invention can obtain a green environment-friendly 3D printing wire.

Description

technical field [0001] The invention relates to a printing wire material and a preparation method thereof. Background technique [0002] With the increasing demand for 3D printing, the types of materials available are gradually increasing, expanding from the initial resin and plastic to metal and ceramics. At present, 3D printing materials mainly include engineering plastics, photosensitive resins, rubber materials, metal materials and ceramic materials. Although there are many types of 3D printing consumables, most of them use high molecular polymers as the main raw materials, such as ABS, PE, PC, etc. These materials are non-degradable materials. It has a certain influence, and the production cost is relatively high. [0003] Patent 201410587283.4 discloses a wooden 3D printing consumable and its preparation method, its components and mass percentages are: wood powder 60%-90%, ABS plastic 3%-15%, PLA 4%-15%, PHA 2% ~10%, PP1% `2% and compatibilizer 1% ~ 2%.
