Insecticidal and antibacterial microporous 3D printing product, and preparation method and application thereof

Abstract

The invention discloses an insecticidal and antibacterial microporous 3D printing product and its preparation method and application. The 3D printing material comprises the following components in parts by weight: 120-140 parts of ABS; 2-8 parts of light diffusing agent 2-8 parts of initiator; 10-20 parts of cross-linking agent; 10-20 parts of coupling agent; 10-30 parts of oyster shell powder; 2-8 parts of bentonite; 1-4 parts of walnut shell superfine powder; ~6 parts; antibacterial agent 4~20 parts; auxiliary agent 0.2~0.4 parts. The invention provides a new variety of 3D printing products for users to choose and use according to their needs. From the perspective of 3D printing, it greatly expands the application and development space of 3D printing products with ABS as the main raw material, which is of great significance.

Description

Technical field [0001] The invention belongs to the field of 3D printing, and specifically relates to a 3D printing product and a preparation method and application thereof. Background technique [0002] With the rapid development of 3D printing technology, the concept of 3D printing has gradually become known to the public. FDM technology uses ABS, polycarbonate (PC), polyphenylsulfone (PPSF), PLA and other thermoplastic materials to be heated and extruded into a semi-molten filament, which is directly constructed from 3D CAD data by depositing on the basis of layers. prototype. This technology is usually used in shaping, assembly, functional testing and conceptual design. In addition, FDM technology can be applied to proofing and rapid manufacturing. [0003] ABS material, ABS, formerly known as acrylonitrile-butadiene-styrene copolymer, is the main core of household fused deposition (FDM) type wire. From the nature of the material, from the point of view of the hot end, ABS ...

Problems solved by technology

However, on the one hand, the smell of this material is very uncomfortable when printing. On the other hand, the printed products have limited functions and cannot meet the diverse needs of the market.

[0004] With the development of science and technology and social progress, 3D printing products are not limited to industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, guns and other fields, but also It has begun to enter people's daily life to make some living utensils or decorations, but the current application in life is still reflected in the use of the shape of the printed product, as well as the artistic design formed by its color and shape, etc. , there is still a lot of room for the application and development of 3D printing, and at the same time, the degradability, toughness and strength need to be further improved
