Abstract

The invention discloses a deodorizing and antibacterial 3D (three-dimensional) printing reed fiber composite material and a preparation method and application thereof. The deodorizing and antibacterial 3D printing reed fiber composite material is prepared from the following components in parts by weight: 50 to 95 parts of macromolecular polymer, 5 to 30 parts of reed fiber, 0.01 to 0.2 part of coupling agent, 1 to 10 parts of toughener, 1 to 30 parts of activated carbon, and 0.1 to 5 parts of antibacterial agent. The deodorizing and antibacterial 3D printing reed fiber composite material has the advantages that on the basis of maintaining the original property of the macromolecular material polymer, the self antibacterial and mildew-proof abilities are improved, and the deodorizing function is improved.

Description

technical field [0001] The invention belongs to the field of polymer composite materials, and in particular relates to a deodorizing and antibacterial 3D printed reed fiber composite material. [0002] technical background [0003] 3D printing technology is a rapid prototyping manufacturing technology that is gradually developing. This is an environmentally friendly and personalized rapid prototyping technology. It has high degree of personalization, small molding volume, low cost, low pollution, and convenient use. advantage. Its basic principle is mainly based on polymer materials, using fused deposition modeling technology, and completing the structure and formation of objects by layer-by-layer printing and accumulation. [0004] The growth of reeds can be seen everywhere in rivers, lakes, ponds, wetlands and ditches with sufficient water all year round. The number is very large, and the collection is convenient and easy, the cost is low, and the performance of reed fiber...
