Problems solved by technology

During the preparation process, the metal powder in the components will be oxidized and blackened or yellowed under high temperature environment twice, and lose the original metallic luster. Therefore, polishing and polishing technology is required to remove the surface oxidation and blackening The metal on the surface of the product will be complex and time-consuming, and the heat generated during the grinding process will also aggravate the oxidation of the surface metal. As time goes on, the contact time between the surface metal and air will prolong, and the metal on the surface of the product will oxidize and blacken again, making The product can only maintain the brightness for a period of time

Embodiment 1

[0027] This embodiment provides a 3D printing material with diamond light sensitivity, including the following components by mass: plastic raw materials: 50 parts of PLA (polylactic acid) and 30 parts of PBS (polybutylene succinate); 15 parts of glass-coated silver powder: toughening agent: 5 parts of polyadipate / butylene terephthalate; nucleating agent: 3 parts of montmorillonite; compatibilizer: maleic anhydride grafted compatibilizer PE-g - 3 parts ST, 1 part Diffuser Oil.

[0028] This embodiment also provides the preparation method of the 3D printing material, specifically:

[0029](1) Preparation of glass-coated silver powder: take 800g of glass particles with an average particle size of 10-200μm as the base material, put them into 2L of industrial deionized water and stir, heat up to 70-80°C, and then add 50mL of 1mol silver powder within 10 minutes / L tin tetrachloride solution to modify the glass surface to facilitate subsequent silver coating; after filtering, add t...

Embodiment 2

[0033] The difference between this example and Example 1 is that the 3D printing material components in this example do not contain nucleating agent: montmorillonite.

Embodiment 3

[0035] The difference between this embodiment and Example 1 is that the 3D printing material of this embodiment includes the following components in parts by mass: plastic raw material: PETG (polyethylene terephthalate-1,4-cyclohexyl 60 parts of alkanedimethanol ester) and 15 parts of TPU (thermoplastic polyurethane elastomer); 10 parts of glass-coated silver powder: toughening agent: 2 parts of polysuccinic acid / butylene terephthalate; nucleating agent: talcum powder 2 parts; compatibilizer: 2 parts of silane coupling agent KH-5500, 0.1 part of diffusing oil.

Abstract

The invention discloses a 3D printing material with diamond light sensation and a preparation method of the 3D printing material. The 3D printing material comprises the following components in parts by mass: 75-99 parts of a plastic raw material, 10-20 parts of glass-coated silver powder, 2-10 parts of a toughening agent, 2-5 parts of a compatilizer and 0.1-2 parts of diffusion oil. According to the invention, the glass-coated silver powder is added into the components, the gloss of the silver powder is close to that of diamond and is not easy to oxidize, and meanwhile, the glass is used as abase material, so that distortion and shearing of the glass in the subsequent process can be avoided, and the complete mirror surface effect of the surface of the 3D printing material in the preparation process is ensured, meanwhile, the preparation process of the glass silver-coated powder is optimized, and the gloss and the mechanical property of the material are remarkably improved, so that theprepared 3D printing material suitable for FDM desktop level has diamond light sensation, is not easy to oxidize and blacken, and is excellent in mechanical property, smooth in printing process, freeof warping, free of fracture and free of wiredrawing.

Description

technical field [0001] The invention belongs to the technical field of 3D printing consumables, and in particular relates to a 3D printing material with diamond light sensitivity and a preparation method thereof. Background technique [0002] 3D printing technology, a type of rapid prototyping technology, also known as additive manufacturing technology, is a method based on digital model files, using bondable materials such as metal, resin or plastic to construct objects by layer-by-layer printing. Technology. [0003] 3D printing is usually achieved using digital technology material printers. It is often used to make models in the fields of mold manufacturing and industrial design, and is gradually used in the direct manufacture of some products. There are already parts printed using this technology. The technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industrie...
