Abstract

The invention relates to a nano zinc oxide / artemisia annua volatile oil / epoxy resin high-performance antibacterial material and a preparation method thereof. The antibacterial material comprises the following components in parts by weight: 10-55 parts of a curing agent; 44-89.6 parts of epoxy resin; 0.2-0.45 parts of artemisia scoparia volatile oil; 0.2-0.45 parts of nano zinc oxide; 0-0.5 parts of an accelerant; wherein the nano-zinc oxide is nano-zinc oxide subjected to surface treatment. On one hand, through the synergistic effect of the two antibacterial agents, the antibacterial activityis enhanced, and the addition amount of the antibacterial agents is reduced; on the other hand, the compatibility of the nano zinc oxide and the epoxy resin is improved, and the mechanical property ofthe composite material is improved. Meanwhile, the process is simple and environmentally friendly, only a common epoxy resin forming method needs to be adopted, special equipment is not needed, the cost is low, and large-scale production is facilitated.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a high-performance antibacterial material and a preparation method thereof, in particular to a nanometer zinc oxide / artemisia volatile oil / epoxy resin high-performance antibacterial material and a preparation method thereof. Background technique [0002] Due to its excellent mechanical properties, electrical insulation properties, processing properties, dimensional stability, and heat and weather resistance, epoxy resins have been widely used in the fields of electronics, aerospace, and coatings. However, the cured epoxy resin has a certain free volume in its cross-linked structure, which makes it vulnerable to moisture intrusion, leading to bacterial growth, shortening its service life, and limiting its application fields. Therefore, the research on antibacterial epoxy resin is of great significance and complies with the concept of sustainable development. [0003] In order to ...
