Abstract

The invention discloses a mosquito-repelling 3D (three-dimensional) printing material and application thereof. The mosquito-repelling 3D printing material comprises, by weight, 110-145 parts of PLA (poly lactic acid), 10-20 parts of anophelifuge, 10-20 parts of cross-linking agent, 2-5 parts of coupling agent, 10-30 parts of sodium lignin sulfonate, 2-20 parts of nano antibacterial agent and 0.1-0.5 part of assistant. The mosquito-repelling 3D printing material and application thereof have the advantages that the network structure of the material is enhanced remarkably, toughness of 3D printing products made of the material is improved effectively, degradation rate is high, antibacterial effect is good, mosquito repelling effect is excellent, and cleanliness is high; more importantly, mint flavone extracts, rosemary extracts and the like in the anophelifuge have mosquito repelling and anti-oxidation effects, and further improves anti-oxidation, sterilization and bacteria inhibition performance and the network structure of the mosquito-repelling 3D printing material as cooperating with other components, thereby having a great significance.

Description

technical field [0001] The invention belongs to the field of 3D printing, and in particular relates to a material for 3D printing and its application. Background technique [0002] With the rapid development of 3D printing technology, the concept of 3D printing is gradually known to the public. FDM technology uses ABS, polycarbonate (PC), polyphenylsulfone (PPSF), PLA and other thermoplastic materials to be heated and extruded into semi-molten filaments, which are deposited on a layer-by-layer basis and constructed directly from 3D CAD data prototype. This technique is commonly used in prototyping, assembly, functional testing and conceptual design. In addition, FDM technology can be applied to proofing and rapid manufacturing. [0003] PLA is a new type of biodegradable material made from starch raw materials proposed from renewable plant resources such as corn. Good mechanical and physical properties, suitable for various processing methods such as blow molding and...
