Abstract

The invention discloses a white copper-based antibacterial master batch for fibers, and a preparation method thereof. The antibacterial master batch comprises 0.4-15% of a white copper-based alloy nano-powder antibacterial agent, 0.2-1.5% of a lubricant, 0.2-1.5% of an antioxidant, 0.2-1.5% of a dispersant, and the balance of matrix resin, and the average particle size of the white copper-based alloy nano-powder antibacterial agent is 200-700 nm. The white copper-based antibacterial master batch for fibers provided by the invention has the characteristics of good antibacterial broad spectrum, good color uniformity and consistency, wide dyeing range, low color matching difficulty and low cost, and the preparation process equipment is simple, convenient, efficient, high in repeatability and wide in application prospect.

Description

technical field [0001] The invention belongs to the field of composite material engineering, and in particular relates to a white copper-based antibacterial masterbatch for fibers and a preparation method thereof. Background technique [0002] Antibacterial fibers have high application value in the preparation of functional antibacterial textiles, functional medical dressings and other fields. Copper can inhibit the growth of bacteria, viruses and fungi at the same time, and has good antibacterial broad-spectrum; at the same time, copper is also one of the trace elements needed by the human body, safe, non-toxic, and environmentally friendly. Copper-based antibacterial fibers can increase the added value of textiles and meet people's needs for safety, health, and environmental protection. Therefore, they have attracted more and more attention and have huge market potential. [0003] At present, the copper-based antibacterial masterbatches for fibers that exist on the market...
