3D printing material with mosquito repellent photosensitive effect and its preparation method and application

Abstract

The invention discloses a 3D (Three-Dimensional) printing material with a mosquito-repelling light-sensitive effect as well as a preparation method and application thereof. The 3D printing material is prepared from the following components in parts by weight: 110-145 parts of PLA (Poly Lactic Acid), 10-20 parts of mosquito repellent, 2-10 parts of sensitization color-variable toner, 2-8 parts of light diffusant, 10-20 parts of cross-linking agent, 2-5 parts of coupling agent, 10-30 parts of sodium lignin sulfonate, 2-8 parts of nanometer antimicrobial and 0.1-0.5 part of auxiliary. According to the preparation method, the network structure of the material is greatly enhanced, the tenacity of the 3D printing product is enhanced, the degradation rate is high, the antibacterial effect is good, and the 3D printing material is light-sensitive and light-variable and has a favorable mosquito-repelling efficacy. Most importantly, the mint flavonoid extract, rosemary extract and the like in the mosquito repellent have a mosquito-repelling effect, and have synergetic effects with other components, so that the oxidation resistance, sterilization and anti-bacteria performance and network structure of the 3D printing material are improved, and the 3D printing material are high in interestingness and practicability and remarkable in significance.

Description

Technical field [0001] The invention belongs to the field of 3D printing, and specifically relates to a material for 3D printing 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] Polylactic acid (PLA) is a new type of biodegradable material, made from starch raw materials proposed by renewable plant resources (such as corn). Good mechanical and physical properties. Polylactic acid is suitabl...

Problems solved by technology

[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
